CEO review

Mike Regnier, Chief Executive Officer, commented

"We remain focused on supporting our customers and delivering products and services that help them make the most of their money. Our expanded digital offer including OneApp, our new mobile banking app which has new functionality for an improved customer experience - is making it easier to use our services. We're also offering competitive savings rates and improved access to mortgage financing.

We've seen an increase in customers choosing our products with more businesses using Banco Santander's global network to trade abroad and continued success with our Edge current account. We will continue to leverage the scale and expertise of Banco Santander to ensure we're offering customers innovative and sustainable products. Looking ahead, we remain well positioned to support our retail and business customers as they benefit from the fall in inflation and improving economic picture.

Our first half financial results were in line with our expectations, with a more positive trajectory reflecting improvements in the second quarter. Our continued prudent approach to risk and balance sheet management means we remain well capitalised with a CET1 capital ratio of 15.4% after dividends and we expect the impact of our pricing actions and the increasing yield from the structural hedge to provide tailwinds in H224."

H124 Financial and Business highlights

We continued to help and support our customers

  • Delivered our new mobile banking app to six million UK customers, following introduction across Spain, Portugal and Poland.
  • Working towards completion of Consumer Duty Phase 2 by 31 July 2024, to ensure continued delivery of good customer outcomes.
  • Grew our CCB business with 320 new clients, providing connections to our global network to support their UK and overseas growth.

Half yearly profit before tax of £813m (H123: £1,122m)

  • Net interest income down 11%, largely due to higher customer deposit costs.
  • Operating expenses up 5%, following further investment in efficiency and customer experience and two years of high inflation.
  • Credit impairment charges down 42%, given the improved economic outlook.
  • Stage 3 ratio1 of 1.59%, up 8bps from 2023, due to a smaller mortgage book and additional single name cases in CCB.

Customer loans and deposits reduced following further disciplined pricing actions

  • While H124 mortgage loans reduced by £4.3bn, we saw improved new business margins and gross lending in the second quarter.
  • Customer deposits reduced by £6.2bn in H124, following savings outflows due to repricing actions taken in Q224.

Strong liquidity, capital and funding

  • RFB DolSub LCR of 140% reducing following TFSME repayments (2023: 157%) with liquidity pool of £45.7bn (2023: £48.3bn).
  • In June 2024 we paid £554bn in interim dividends.
  • CET1 capital ratio of 15.4% (2023: 15.4%), well above minimum requirements.
  • Stable and diversified wholesale funding programmes.

Looking ahead

  • We intend to continue to prioritise profitability, capital generation and our core banking franchise in 2024, through planned balance sheet optimisation, resulting in lower mortgage lending and customer deposits.
  • Pricing actions taken and increasing yield from the structural hedge positively impacted our net interest margin towards the end of Q224, providing a tailwind into H224.

Retail & Business Banking

– Profitability decreased with higher costs of deposits seen across the market. Pricing actions on deposits started to impact margins in the second quarter and will provide a tailwind in H224.

Consumer Finance

– Lower lending than H123, as a decision was made to focus on value and capital generation.

Corporate and Commercial Banking

– Profitability decreased in line with the factors described above that led to the decrease in profit before tax on a consolidated basis. Growth from high value new to bank clients and balance sheet management. Focus on clients' international needs, connecting 1,500 companies to our global network to support their international growth in 2024.

Principal risks and uncertainties

A description of our principal risks and uncertainties for the remaining six months of the financial year is set out in the Risk governance section of the Risk review, mainly in Top risks and Emerging risks as well as a discussion of how the relevant risks and uncertainties have changed since our 2023 Annual Report was published.

Alternative Performance Measures (APMs)

In addition to the financial information prepared under IFRS, this half yearly Financial Report contains non-IFRS financial measures that constitute APMs, as defined in ESMA guidelines.

Risk governance

INTRODUCTION

As a financial services provider, managing risk is a core part of our day-to-day activities. To be able to manage our business effectively, it is critical that we understand and control risk in everything we do. We aim to use a prudent approach, underpinned by advanced risk management techniques to help us deliver robust financial performance, withstand stresses, and build sustainable value for our stakeholders. We aim to keep a predictable medium-low risk profile, consistent with our business model. This is key to achieving our strategic objectives.

RISK FRAMEWORK

How we define risk

Key risk types

Our key risk types help us define the risks to which we are exposed. For definitions of our key risk types, see 'How we define risk' in the 2023 Annual Report.

30 June 2024 compared to 31 December 2023

In H124, our key risk types remained as described in the 2023 Annual report, except for that Operational risk and resilience is now referred to as Operational risk.

Top and emerging risks

Several of our risk types also have top and/or emerging risks associated with them. For more, see 'Top and emerging risks' in the 2023 Annual Report.

30 June 2024 compared to 31 December 2023

In H124, there were no significant changes in our risk governance and our top and emerging risks, as described in the 2023 Annual Report, except as follows:

Top risks

In H124, our focus shifted away from Inflationary and Supply Chain pressures to Margin Compression risk. UK headline inflation reduced towards the 2% UK government target and markets indicated a peak in the bank rate. Our Asset & Liability Committee approved and implemented a strategy to manage and mitigate the risks of margin compression. We also introduced Resiliency, Payments Transformation and Artificial Intelligence (AI) / Machine Learning risks as new specific top risks, although these were already monitored within the existing risk types and through our Emerging Risks assessment. We removed People risk as a top risk, though this continues to be monitored as part of our strategic transformation programme.

Other Top risk profile movements

We continued maturing our Financial Crime (FC) oversight capabilities and our Centre of Excellence operations to further integrate FC risk management across the business. We continued to review our operations and processes to maintain an appropriate response to the fluidity and complexity of global sanctions regimes and deploying supplemental technology in our screening processes. Enhancements in fraud prevention, delivered by our Fraud Transformation Programme, led to a reduction in fraud losses in H124 compared to the same period in 2023. Our planning is progressing well to meet the Payment Systems Regulator (PSR) new mandatory reimbursement requirement implementation date of 7 October 2024.

We continued to focus on Conduct and Regulatory risk matters, with significant regulatory engagement across a number of areas. These include FC, Technology, Regulatory models, Outsourcing and Third-Party Risk Management, Data Privacy, and Operational Resiliency. We maintained our focus and attention on the Consumer Duty, with a significant number of enhancements realised for on-sale and off-sale products and services across business and support areas, aligned to the requirements of the Duty. Additionally, we enhanced and implemented processes and tools to evolve our monitoring and delivery of good customer outcomes.

Technology remains at the centre of our non financial risk activities, and we continued to progress our bank-wide programme to address key risks in our IT estate, including platform obsolescence. The programme continues to deliver risk reduction, with improvements being monitored closely through our risk governance framework. There was elevated media coverage relating to a Banco Santander Group cybersecurity incident, including access of certain information. Updates on root cause analysis are being finalised with the PRA and FCA. The incident did not have a material effect on Santander UK. The cybersecurity threat remains elevated given heightened geopolitical tensions, with additional risks presented by advances in technology (including AI).

Risks associated with our strategic transformation plans include execution risks, funding prioritisation, and risks from ongoing cost reduction and efficiency focused initiatives. We have robust governance oversight and continuous change portfolio reviews to ensure appropriate strategic and risk-based prioritisation whilst ensuring that we have the capacity and sequencing in place to deliver.

In H124 we introduced three new specific top risks. Resiliency risk reflects the importance of complying with operational resiliency requirements by the regulatory deadline of March 2025. Payment Transformation risk addresses the rapidly-evolving payments industry landscape with new regulatory requirements and scheme changes and adoption of new technology and standards. Thirdly, AI / Machine Learning risk considers our preparedness to safely manage and respond to AI developments given the pace and scale of change anticipated in this space.

Emerging risks

Macroeconomic and geopolitical risks remain in our top areas of focus with the potential to reignite inflationary pressures and impact the UK economy and the financial services industry. Geopolitical tensions could also escalate further and increase operational resilience risks via cybersecurity attacks. We continued to enhance our threat prevention controls and test our business area recovery plans against a range of scenarios. In the UK, political risks to the banking sector are in focus, driven by potential risks from changes in government policy following the 2024 General Election, which could impact our business plans. We monitor the political landscape closely, and our Public Affairs team gives specialist insights and analysis which we use to assess potential impacts to Santander UK.

Other Emerging risk profile movements

Complex regulatory agenda and fast technological change remain our other top ranked emerging risks. In H124 the Bank of England and HM Treasury published their response to the Digital Pound consultation. We monitor progress related to this initiative via our Regulatory Liaison team and will review the potential impacts on us and the wider industry, such as risks of loss of customer deposits and higher wholesale funding costs.

Our risk culture programme

In H124, we enhanced our approach to how we think about risk by formally introducing Risk Pro. Risk Pro is how we think and behave when it comes to risk, and builds on the focus on processes and risk management of I AM Risk. Risk Pro will help build our risk-related skills and capabilities, so everyone has the bravery and belief in their ability to do the right thing, using our TEAMS behaviours as described in the 2023 Annual Report. Risk Pro also aligns our approach more closely with the wider Banco Santander group. To help develop a Risk Pro mindset, we re-designed our risk mandatory training to focus on the risk mindset and behaviours.

Credit risk

Overview

Credit risk is the risk of financial loss due to the default or credit quality deterioration of a customer or counterparty to which we provided credit, or for whom we assumed a financial obligation.

Credit risk management

In H124, there were no significant changes in the way we manage credit risk as described in the 2023 Annual Report except for the new impairment models for Retail Mortgages and CCB, and updates to our Significant Increase In Credit Risk (SICR) rules. These are explained below.

Credit risk review

In this section, we analyse our key credit risk metrics.

Introduction

We manage credit risk across all our business segments in line with the credit risk lifecycle. We tailor the way we manage risk across the lifecycle to the type of customer. There have been no significant changes in the way we manage credit risk as described in the 2023 Annual Report except for:

  • We implemented new impairment models for Retail Mortgages and CCB to embed long standing JAs into the model, update the model's calibration and refine the methodology for Loss Given Default (LGD) and increase the speed of production.
  • We also took the opportunity to update our Stage 2 SICR criteria to enhance and improve consistency across portfolios.
  • The changes from SICR and model changes increased Stage 2 exposures by £0.7bn across all portfolios with only a modest impact on ECL of £30m. The implementation of the second generation models for Retail mortgages and CCB resulted in a £23m release.

Recognising ECL

The ECL approach estimates the credit losses arising from defaults in the next 12 months on qualifying exposures, or defaults over the lifetime of the exposure where there is evidence of a SICR since the origination date. The ECL approach takes into account forward-looking data, including a range of possible outcomes, which should be unbiased and probability-weighted to reflect the risk of a loss being incurred even when it is unlikely.

Multiple economic scenarios and probability weights

For all our portfolios we use five forward-looking economic scenarios. At 30 June 2024, they consisted of a central base case, one upside scenario and three downside scenarios. We use five scenarios to reflect a wide range of possible outcomes for the UK economy.

Our forecasting approach

In H124, there were no significant changes in our forecasting approach as described in the 2023 Annual Report.

Base case

We review the scenarios and associated weights every quarter to ensure they appropriately reflect the current economic circumstances, and UK Government policy which is subject to change in this fluid environment.

In summary, the outlook for the UK economy in 2024 sees GDP recovering after two years of trivial growth, inflation remaining slightly above the 2% target and bank rate falling further. Geopolitical events may create the potential for further inflationary episodes and with productivity growth expected to remain weak, this will limit medium-term prospects. In addition, robust wage growth remains a key risk to inflation remaining at the 2% target.

Base case key macroeconomic assumptions

  • House price growth: The sharp rise in mortgage rates triggered a slowdown in house price growth in recent months, with survey indicators pointing to a slump in buyer demand as confidence is hit by a squeeze on affordability. However, once the bank rate starts to fall in H224, this should result in a modest recovery in house price growth. We forecast a 2.5% year-on-year rise in house prices by the end of 2024, with a further increase of 3% by the end of 2025. In the medium term, annual property price increases are projected to remain broadly in line with average household disposable income growth of c.3-4%.
  • GDP: GDP rebounded in Q124 ending the mild technical recession at the end of 2023. PMI data suggests that positive growth was maintained in Q224, albeit at a weaker pace than Q124's 0.7% expansion. Zero growth in April and 0.4% expansion in May means that even if output flatlines in June, activity in Q2 will be similar to Q1. With business and consumer confidence improving in response to lower inflation and interest rates, these factors are expected to support a consumer-led recovery in GDP with growth averaging 1.3% per annum over the forecast period. The main headwind to economic growth is weak productivity. The evolution of AI and other government policies may allow the UK's services-orientated economy to exploit new technologies to improve efficiency.
  • Unemployment rate: Unemployment rose to 4.4% in the three months to May 2024, up from 4.2% in January 2024 and 3.9% at the end of 2023. Job vacancies fell to 889k in the three months to June 2024, 151k lower than a year earlier but still 93k above pre-pandemic levels. With companies under pressure from rising debt servicing costs and higher wages, it is likely that some will become insolvent, although we do not envisage a large rise in unemployment. The jobless rate peaks at 4.4% by the end of 2024, in part impacted by the ongoing return of previously inactive workers to the labour force.
  • Bank Rate: The Monetary Policy Committee (MPC) cut the Bank rate by 0.25% to 5.00% at the August 2024 meeting. Our base case had assumed a 25bps cut in August 2024 followed by a further reduction in November 2024, taking the bank rate to 4.75% by the end of 2024. Four cuts are projected in 2025 to leave the bank rate at 3.75%, followed by another 75bps of loosening through the rest of the five-year forecast period taking the terminal rate to 3.00%.
  • CRE price growth: CRE is assumed to have reached its trough in 2024 with growth rates improving for the rest of the five-year forecast period. However, the bounce back in growth remains relatively muted as although the bank rate is cut, it is not to a level that would help create stronger growth. The issue of fully utilised office space and the effect this has on price growth remains, due to the shift to working from home.

In the medium-term, the projections assume that current demographic and productivity trends will continue, limiting scope for an improvement in the UK's growth potential. For instance, it is likely that the reduction in the UK workforce continues and that this will have a knock-on impact for the economy, particularly if there are shortages of skilled workers in particular sectors. This is reflected in an average annual growth expectation of 1.3%, below the OBR's latest estimate of the UK's long run average growth rate. CPI inflation is forecast to remain above the 2% target rate for most of the initial five-year forecast period.

Key changes to our base case in H124

Our base case has been updated to reflect stronger growth seen in H124. We now forecast two bank rate cuts rather than three later in 2024, this contributes to a slower rise in house price growth.

For our base case, we expect the economy to recover gradually following the mild technical recession in H223. Headwinds include weak productivity growth, an unstable geopolitical environment.

The key changes to our base case assumptions in H124 were: (i) the 2024 GDP growth forecast was revised up in response to stronger growth momentum and the improvement in business and consumer confidence indicators; (ii) the strength of services inflation (linked to robust wage growth) means headline CPI remains above the 2% target for most of the forecast period; (iii) a shallower bank rate profile, with cuts starting in H224; and (iv) house prices are 2.5% higher by the end of 2024 with a further increase of 3% by the end of 2025.

Other scenarios

Based on this revised base case, we have reviewed our suite of scenarios to ensure that they capture the wide range of potential outcomes for the UK economy. These include (i) reflecting persistent above target inflation over the forecast period; (ii) a slower recovery that is more akin to the 'U' shape of past recessions; (iii) labour market frictions due to skills mismatches and a shrinking workforce as some discouraged workers leave altogether (for example older UK-born workers retiring early and longer term sickness levels remaining above pre-pandemic levels); and (iv) the global economy recovering more swiftly from higher inflation.

To reflect these potential outcomes, we decided to continue to use the base case and four additional scenarios, which we consider provides a range wide enough to reflect all the above potential outcomes. With risks still skewed to the downside we concluded that only one upside scenario was needed to reflect the upside risks to the base case.

The four other scenarios are:

One upside scenario

This scenario has a quicker recovery in growth than the Baseline and is a bull case to the base forecasts. It assumes that inflation falls slightly below target at the start of the forecast period helped by lower wage growth, and rises back above 2% over the period. This allows the Bank of England to cut rates earlier, bringing them back towards what might be considered the neutral rate, earlier than the base case. This results in higher consumer and business confidence enabling higher levels of spending and investment, with savings rates returning to levels consistent with economic growth as real earnings growth returns. GDP remains stronger than the base case, with house prices remaining relatively stable despite a modest increase in unemployment and inflation falling back to target and remaining there over the forecast horizon.

Three downside scenarios

Downside 1 - This scenario is a bear case to the baseline. In this scenario, consumers opt to save more rather than spend, as consumer confidence remains low, partly reflecting concerns about the unstable geopolitical environment. House prices fall as more households look to downsize to lower their mortgage repayments in case of unemployment or a squeeze on incomes due to the higher tax burden. With inflation remaining above target, the bank rate remains in restrictive territory as core inflation stays above the baseline view, before cuts start as inflation falls back.

Stubborn inflation - The scenario considers the effect on the UK economy of a persistent inflationary environment. Here inflation fluctuates but remains above the Bank of England target for the entire forecast period due to both UK specific issues such as higher wage growth but also due to external factors such as geopolitical instability. Although inflation does not rise to the peak seen in 2022, it remains stubbornly above the 2% inflation target throughout the five-year forecast period. This causes a peak to trough fall in GDP of c-2.5% and a much higher bank rate profile with a peak of 6% to combat persistently higher inflation. House prices fall c.20% which is similar to the Global Financial Crisis (GFC).

Downside 2 - This scenario is similar in severity to a typical stress test scenario. It shows a marked fall in GDP, with unemployment rising to levels consistent with the GFC and house prices falling by almost a third. The scenario also reflects ongoing strike action by various unions pushing for stronger pay growth, alongside the increase in geopolitical risk which affects market sentiment and causes further fragmentation of the global economy. It also assumes that major risk events continue to occur, exposing countries' fiscal vulnerabilities and their ability to respond to such events. For this scenario, an overlay to the UK unemployment rate was also made to the model output from the OGEM. This was to account for the possibility of a recession of similar size to that of 2008/09 where the unemployment rate peaked at 8.5%.

Key changes to our alternative scenarios in H124

The downside scenarios capture a range of risks, including further escalation of geopolitical events, continuing weaker investment; reflecting the unstable environment; a continuing and significant mismatch between job vacancies and skills, as well as a smaller labour force; and political uncertainty due to a change of government following the July 2024 general election.

In H124, there were no significant changes in our alternative scenarios as described in the 2023 Annual Report.

Scenario weights

Each quarter, we undertake a full review of the scenario weights we apply. We consider the weighting of the economic scenarios as a whole, while ensuring that the scenarios capture the non-linear distribution of losses across a reasonable range. To support our initial assessment of the weighting of a scenario, we undertake a Monte Carlo analysis to find out the likelihood of a five-year average GDP forecast growth rate occurring based on the long run historically observed average. Creating a standard distribution bell curve around this long run average provides an estimate of the probability of a given GDP scenario occurring based on past experience and therefore assign a provisional weight to that scenario.

The scenario weights we applied for 30 June 2024 and 31 December 2023 were:

Upside Base case Downside 1 Stubborn
Inflation
Downside 2 Weighted
Scenario weights % % % % % %
30 June 2024 10 50 20 10 10 100
31 December 2023 10 50 10 20 10 100

30 June 2024 compared to 31 December 2023

Now that the effects of the pandemic in terms of large GDP growth swings have passed, the Monte Carlo analysis returns to being based on data in the post GFC period from 2009 onwards in line with how it was being used pre-pandemic. For H124, all downside scenarios sit between the 60th and 80th percentiles suggesting a lower weight than the base case remains appropriate.

We also need to consider the UK's economic and political environment when applying the weights. With risks still heavily skewed to the downside we believe it is appropriate to weigh the scenarios to reflect this. These risks include: the ongoing cost of living challenges for households given the c.25% rise in prices since the start of the pandemic; a further escalation in geopolitical tensions creating extra challenges for economies globally including the UK; a continuation of upside inflation surprises causing inflation to stay above target for longer; continuing weak investment reflecting the uncertain economic environment, and a continuing and significant mismatch between vacancies and skills alongside a smaller labour force.

In H124, we increased the weight on the Downside 1 scenario by 10% with a corresponding decrease in our Stubborn Inflation scenario to rebalance the overall weighted ECL and to reflect the fact that the economic growth outlook has improved since the end of 2023.

Significant Increase in Credit Risk (SICR)

Loans which have suffered a SICR since origination are subject to a lifetime ECL assessment which extends to a maximum of the contractual term of the loan, or the behavioural term for a revolving facility. Loans which have not experienced a SICR are subject to 12-month ECL. We assess the credit risk profile of each facility to determine which of three stages to allocate them to:

  • – Stage 1: when there has been no SICR since initial recognition. We apply a loss allowance equal to a 12-month ECL i.e. the proportion of lifetime expected losses that relate to that default event expected in the next 12 months
  • – Stage 2: when there has been a SICR since initial recognition, but the exposure is not considered credit impaired. We apply a loss allowance equal to the lifetime ECL i.e. the expected loss resulting from all possible defaults throughout the residual life of a facility
  • Stage 3: when the exposure is considered credit impaired. We apply a loss allowance equal to the lifetime ECL. Objective evidence of credit impairment is needed. For more, see the section 'Definition of default (Credit impaired)' in the 'Credit risk' section of the Risk review in the 2023 Annual Report.

We use quantitative, qualitative and backstop criteria to identify exposures that suffer a SICR. The Credit Risk Provisions Forum (CRPF) reviews and approves our SICR thresholds periodically. The Board Audit Committee reviews and challenges their appropriateness each year, or more often if we change them.

Key changes in H124

In H124, alongside our new ECL models, we updated our SICR criteria to enhance and improve consistency across portfolios. As a result, we now treat the following accounts as Stage 2:

– Quantitative:

  • Accounts with a 12-month PD between 30bps (0.3%) and 2000bps (20%) where the annualised lifetime PD has doubled from origination.
  • PD threshold: Accounts where the annualised lifetime PD has increased above 2000bps (20%).
  • Low Credit Risk Exemption (LCRE): we introduced an LCRE where, if the 12-month PD is less than 30bps, we retain the account in Stage 1, unless the qualitative or backstop criteria are met.

These changes increased the number of accounts in Stage 2 for Credit Cards and Overdrafts mainly due to the lower absolute PD thresholds with no material increase in ECL.

– Qualitative:

  • For Mortgages, over-indebted customers and Interest-only accounts 24 months pre-maturity.
  • For CCB, customers operating in a high-risk sector.
  • These enhancements enabled us to retire related JAs.

Quantitative criteria

We use quantitative criteria to identify where an exposure has increased in credit risk. We base our criteria on whether any increase in the lifetime PD since origination exceeds a threshold in relative and absolute terms. We base the value anticipated at origination on similar assumptions and data to the ones we use at the reporting date, adjusted to reflect the account surviving to that date. The comparison uses either an annualised lifetime PD, where the lifetime PD is divided by the forecast period, or the absolute change in lifetime PD since origination.

The criteria for H124 and 2023 were: accounts above the lower absolute PD thresholds below, where the PD has doubled since origination, are treated as Stage 2. At 30 June 2024, any account above the upper threshold (i.e. 20%) is also treated as Stage 2:

31 December 2023 30bps 30bps 340bps 260bps 300bps 30bps Internal rating method

(1) For larger business banking customers, we apply the same criteria as we use for CCB. Credit cards and Overdrafts lower PD thresholds aligned with the rest of Everyday Banking at 30 June 2024 for consistency. (2) Consumer Finance use the comparison of lifetime PDs to determine Stage allocation, unlike other products which first turn the lifetime PD into an average yearly PD (annualised) and then do the comparison. In addition, Consumer Finance does not apply the upper absolute PD threshold criteria.

Qualitative criteria

We also use qualitative criteria to identify where an exposure has increased in credit risk, independent of changes in PD. The criteria forH124 and 2023 were:

(1) For larger business banking customers, we apply the same criteria that we use for Corporate & Commercial Banking.

If needed, we apply additional qualitative assessment as part of Judgemental Adjustments in response to situations where known or expected risk factors and information are not considered in the modelling process. See 'Judgemental Adjustments (JAs)' below for more on this.

Backstop criteria

As a backstop, we classify all exposures more than 30 or 90 DPD in at least Stage 2 or in Stage 3, respectively. This means that we do not rebut the backstop presumptions in IFRS 9 (i.e. credit risk has significantly increased if contractual payments are more than 30 DPD) relating to either a SICR or default.

Improvement in credit risk or cure

We transfer Stage 3 exposures to Stage 2 or Stage 1 when we no longer consider them to be credit impaired. We transfer Stage 2 exposures to Stage 1 when we no longer consider them to have suffered a SICR. Where we identified a SICR using quantitative criteria, we transfer the exposures to Stage 1 when they no longer meet the original PD-based transfer criteria. Where we identified a SICR using qualitative criteria, the issues that led to the transfer must be cured before we transfer the exposure to Stage 1. For a loan to exit forbearance, it must meet the conditions set out in the section 'Forbearance' in the 'Credit risk' section of the Risk review in the 2023 Annual Report.

30 June 2024 compared to 31 December 2023

In H124, we implemented new Retail Mortgages and CCB impairment models, which now embed Long-term underlying arrears, 12+months arrears, Model Underestimation, and Mortgages Secured Affordability JAs. The new CCB model also captures the risks associated with Corporate customers operating within higher risk sectors reducing the level of CCB JAs.

In response to the improved economic data, specifically inflation, we re-assessed the need for cost of living JAs and retired the Secured and Unsecured Affordability JAs.

In H124, we introduced a new Mortgage LGD JA which adjusts the historically observed experience for Stage 3 accounts due to specific factors which have temporarily suppressed possession and litigation activity.

As a result, JAs reduced from £184m to £94m. The proportion of JAs to total ECL decreased from 19% to 10%.

Sensitivity of ECL allowance

The ECL allowance is sensitive to the methods, assumptions and estimates underlying its calculation. For example, management could have applied different probability weights to the economic scenarios. In addition, the ECL for residential mortgages is significantly affected by the HPI assumptions which determine the valuation of collateral used in the calculations.

Had management used different assumptions on probability weights and HPI, a larger or smaller ECL charge would have resulted that could have had a material impact on the ECL allowance and profit before tax. We have incorporated JAs into the sensitivity analysis, and these assumptions are set out below.

Scenario sensitivity

The tables below show the ECL allowances that would have arisen had management applied a 100% weight to each economic scenario. The allowances were calculated using a stage allocation appropriate to each scenario and differs from the probability-weighted stage allocation used to determine the ECL allowance shown above. For exposures subject to individual assessment, the distribution of ECL which could reasonably be expected has also been considered, assuming no change in the number of cases subject to individual assessment, and within the context of a potential best to worst case outcome.

30 June 2024 compared to 31 December 2023

ECL reduced by £34m since 31 December 2023. Mortgages, CCB and EDB - Other all decreased due to an improved economic outlook driving ECL model releases. The ECL on Credit Cards increased due to updated SICR rules. The value of JAs decreased in H124 due to the implementation of new impairment models for Mortgages and CCB, as well as the release of the cost of living JAs on the Unsecured portfolio.

30 June 2024 compared to 31 December 2023

Mortgage assets continued to fall following further disciplined pricing actions to optimise the balance sheet given higher funding costs continuing to contribute to a reduction in mortgage lending. In H124, early and late arrears remained at low levels despite a slight increase across the portfolio over the period.

Loans in Stage 2 and 3 remain low compared to historic trends although, as expected we saw an increase in arrears in H124. While underlying asset quality remains good, we saw an impact from changes to our SICR criteria. These were updated in H124 and increased Stage 2 loans for mortgages and credit cards.

30 June 2024 compared to 31 December 2023

The ECL provision at 30 June 2024 decreased by £34m to £958m (2023: £992m) with a £37m release of JAs related to cost of living and a change in our economic assumptions and weightings.

Total coverage 0.1 2.0 11.8 0.3

6-month gross write-off utilisation of £98m (H123: £97m) largely driven by unsecured retail.

Key movements in exposures and ECL in H124 by Stage were:

  • Stage 1 exposures reduced mainly due to lower mortgage new business, slowing of the housing market and customers reducing debt in response to continued higher interest. Stage 1 ECL also reduced due to the reduction in mortgage assets and the economic assumption updates.
  • Stage 2 exposures also reduced during the period driven by Corporate and Commercial Banking assets moving from Stage 1 to Stage 2 following the implementation of new impairment models. Stage 2 ECL reduced primarily due to the update of economic assumptions and the implementation of new impairment models.
  • Stage 3 exposures increased in H124 primarily due to the deterioration of single name cases in Corporate and Commercial Banking. This also drove an increase in ECL for Corporate and Commercial Banking, however Mortgages ECL reduced following the implementation of new impairment models.

Reconciliation of exposures, loss allowance and net carrying amounts

The table below shows the relationships between disclosures in this Credit risk review section which refer to drawn exposures and the associated ECL, and the total assets as presented in the Consolidated Balance Sheet. The Credit risk review disclosures exclude Joint ventures, as they carry low credit risk and therefore have an immaterial ECL, and Other items, mainly accrued interest that we have not yet charged to the customer's account and cash collateral.

(1) Exposures that have attracted an ECL, and as reported in the Credit Quality table above.

(2) Changes to assumptions in the period. Isolates the impact on ECL from changes to the economic variables for each scenario, the scenarios themselves, and the probability weights from all other movements. Also includes the impact of quarterly revaluation of collateral. The impact of changes in economics on exposure Stage allocations are shown in Transfers of financial instruments.

(3) Total impact of facilities that moved Stage(s) in the period. This means, for example, that where risk parameter changes (model inputs) or model changes (methodology) result in a facility moving Stage, the full impact is reflected here (rather than in Other). Stage flow analysis only applies to facilities that existed at both the start and end of the period. Transfers between Stages are based on opening balances and ECL at the start of the period.

(4) Relates to the revaluation of ECL following the transfer of an exposure from one Stage to another.

(5) Exposures and ECL of facilities that did not exist at the start of the period but did at the end. Amounts in Stage 2 and 3 represent assets which deteriorated in the period after origination in Stage 1. (6) Residual movements on existing facilities that did not change Stage in the period, and which were not acquired in the period. Includes the net increase or decrease in the period of the mortgage pipeline, cash at

central banks, the impact of changes in risk parameters in the period, unwind of discount rates and increases in ECL requirements of accounts which ultimately were written off in the period. (7) Exposures and ECL for facilities that existed at the start of the period but not at the end.

(1) 'Home movers' include both existing customers moving house and taking out a new mortgage with us, and customers who switch their mortgage to us when they move house.

(2) 'Remortgagers are new customers who are taking a new mortgage with us.

As well as the new business in the table above, there were £18.1bn (H123: £15.4bn) of remortgages where we moved our customers with maturing mortgages onto new ones. We also provided £0.4bn (H123: £0.4bn) of further advances and flexible mortgage drawdowns. 77% (2023: 77%) of customers with a maturing mortgage were retained, which applied to mortgages three months post maturity, based on a 12-month average of retention rates to March 2024.

30 June 2024 compared to 31 December 2023

In H124, mortgage asset stock decreased across all sectors, with the stock borrower profile unchanged. Our new business increased year-on-year in all sectors due to increased lending appetite as economic pressures continued to ease, allowing for improved lending margins. However, this increase in new business lending has not offset repayments and redemptions in the period, so the book continued to deleverage. In H124, we helped first-time buyers buy their new home with £1.8bn of gross lending (H123: £1.0bn).

Interest rate profile

The interest rate profile of our maturing mortgage asset stock was:

30 June 2024 compared to 31 December 2023

In H124, we continued to see customers refinance from SVR and FoR to fixed rate products influenced by continued higher interest rates, with a slight increase in demand for variable rate products tracking the Bank of England base rate. We continued to see more customers choosing shorter-term fixed rate products in H124.

Loan-to-value analysis

This table shows the LTV distribution for the gross carrying amount and the related ECL of our total mortgage portfolio and Stage 3 mortgages, and new business. We also show the collateral value and average LTV. We use our estimate of the property value at the balance sheet date and include fees that have been added to the loan. For flexible products, we only include the drawn amount, not undrawn limits.

(1) Collateral value is limited to the balance of each loan and excludes the impact of any over-collateralisation. Includes collateral against loans in negative equity of £355m (2023: £389m). (2) Balance weighted LTV = (Loan 1 balance x (Loan 1 Balance/Loan 1 latest property valuation) + (Loan 2 balance x (Loan 2 balance/Loan 2 latest property valuation) + ...) /(Loan 1 balance + Loan 2 balance+...).

At 30 June 2024, the parts of loans in negative equity which were effectively uncollateralised before deducting loss allowances was £52m (2023: £56m). The balance weighted average LTV of new business in the period in London was 64% (2023: 65%). £70.5bn of new business and internal transfers were priced in 2023 and H124, and by the end of the year a further £17bn will reach the end of the incentive period. Arrears from recent internal transfers remain low, with less than 1% of customers entering arrears within 12 months.

30 June 2024 compared to 31 December 2023

There were no significant changes in collateral quality in H124. Balance weighted average LTVs of stock and new business were broadly flat as economic pressures eased and mortgage market trends remain steady. We monitor the profile of new lending and take action as needed to ensure the LTV mix of completions is in line with our risk appetite.

30 June 2024 compared to 31 December 2023

In H124, the combined total proportion of interest-only loans, part interest-only, part repayment loans and flexible loans was broadly stable at 32.2% (2023: 32.9%).

BTL mortgage balances decreased £0.5bn to £15.1bn (2023: £15.6bn) driven by our strategy to deleverage our mortgage portfolio and changes in market dynamics. In H124, the balance weighted average LTV of mortgage total new BTL lending was 56% (2023: 58%).

Business Banking assets continued to reduce primarily due to the pay down of the BBLs portfolio. Total Stage 2 assets also reduced driven by Personal Loans and Overdrafts, due to the release of the cost of living JAs. However, Credit Cards saw an increase due to the updated SICR rules. 57% (2023: 55%) of credit card customers repay their balance in full each month and UPL average customer balances remained unchanged at £6,000.

In H124, we maintained our prudent Consumer (auto) finance underwriting criteria. The product mix was broadly unchanged, with wholesale balances decreasing slightly.

Lower lending in H124 than H123, as a decision was made to focus on value and capital generation. At 30 June 2024, Consumer (auto) finance gross lending (new business) was £752m (H123: £1,114m). Wholesale loans (Stock finance) to car dealerships at 30 June 2024 were approximately 8.6% (2023: 9.9%) of the Consumer loan book. At 30 June 2024, the average Consumer (auto) finance loan size was £15,484 (2023: £17,308).

The risk profile was stable in terms of our credit scoring acceptance policies. The overall risk performance was good with the vast majority of customers paying.

CORPORATE CENTRE – CREDIT RISK REVIEW

Committed exposures

Rating distribution

Corporate Centre committed exposures mainly comprise Sovereign exposures and Structured Products (High Quality Liquid Assets, mainly Asset Backed Securities and covered bonds) managed as part of our Eligible Liquidity Pool. These are low risk, high quality, investment grade exposures with a credit rating of 8 or 9 according to our internal rating scale (see the 'Santander UK group level – credit risk review' section).

Geographical distribution

We typically classify geographical location according to the counterparty's country of domicile unless a full risk transfer guarantee is in place, in which case we use the guarantor's country of domicile instead. At 30 June 2024 and 31 December 2023 this is mainly focused in the UK.

Credit performance

We monitor exposures that show potentially higher risk characteristics using our Watchlist process. In Corporate Centre, committed exposures were all fully performing at 30 June 2024 and 31 December 2023.

Liquidity risk

Overview

Liquidity risk is the risk that, while still being solvent, we do not have the liquid financial resources to meet our obligations when they fall due, or we can only get them at high cost.

Liquidity risk management

In H124, there were no significant changes in the way we manage liquidity risk as described in the 2023 Annual Report.

Liquidity risk review

In this section, we analyse our key liquidity metrics and our wholesale funding. We also provide information on asset encumbrance.

30 June 2024 compared to 31 December 2023

We remained in a strong liquidity position. We held sufficient liquid resources and had adequate governance and controls in place to manage the liquidity risks arising from our business and strategy. At 30 June 2024 and 31 December 2023, the LCR and NSFR significantly exceeded regulatory requirements.

In H124, Santander UK purchased UK Gilts on a 'Hold-To-Collect-Cash-flows' basis. The notional value at 30 June 2024 was £1.5bn (2023: £nil).This means that there is an increased allocation of liquid assets to longer-dated UK sovereign bonds to support ongoing HQLA requirements. In line with the rest of the LCR eligible liquidity pool, term duration is hedged with swaps to offset mark to market movements from interest rate changes.

FUNDING RISK REVIEW

Our funding strategy continues to be based on maintaining a conservatively structured balance sheet and diverse sources of funding to meet the needs of our business strategy and plans. The CFO Division maintains a funding plan that complies with our LRA and regulatory liquidity and capital requirements.

Maturity profile of wholesale funding

This table shows our main sources of wholesale funding. It does not include securities finance agreements. The table is based on exchange rates at issue and scheduled repayments and call dates. It does not reflect the final contractual maturity of the funding.

Encumbrance

Encumbrance of customer loans and advances

We issued securitised products to a diverse investor base through our prime mortgage-backed and other asset-backed funding programmes. We raised funding with mortgage-backed notes, both issued to third parties and retained – the latter being central bank eligible collateral for funding purposes in other Bank of England facilities. We also have a covered bond programme, under which we issue securities to investors secured by a pool of residential mortgages. For more on these programmes, see Notes 14 and 26 to the Consolidated Financial Statements in the 2023 Annual Report.

30 June 2024 compared to 31 December 2023

Our level of encumbrance from external and internal issuance of securitisations and covered bonds increased in H124 to £33.2bn (2023: £27.9bn).

Capital risk

Overview

Capital risk is the risk that we do not have an adequate amount or quality of capital to meet our internal business needs, regulatory requirements and market expectations.

Capital risk management

In H124, there were no significant changes in the way we manage capital risk as described in the 2023 Annual Report.

Capital risk review

In this section, we analyse our capital resources and key capital ratios.

CAPITAL RISK REVIEW

Meeting evolving capital requirements

We target a CET1 management buffer of sufficient size to absorb volatility in CET1 deductions, capital supply and capital demand whilst remaining above the current and expected future regulatory CET1 requirement. Distribution restrictions would be expected to be applied if we were unable to meet both our minimum requirement, which consists of the Pillar 1 minimum plus Pillar 2A, the CRD IV buffers consisting of the Capital Conservation Buffer (CCB), the Countercyclical Capital Buffer (CCyB), and the Other Systemically Important Institutions Buffer (O-SII).

(1) Based on modelling assumptions of repricing behaviour.

30 June 2024 compared to 31 December 2023

In H124, we continued to actively manage the structural position in line with non-rate sensitive liabilities in order to manage interest rate risk.

NII sensitivity is adversely exposed to down shock-scenarios driven by margin compression of core liabilities, offset by the structural position. EVE sensitivity is adversely exposed to rising interest rate scenarios. In H124 EVE sensitivity increased and NII sensitivity decreased mainly reflecting the overall increase in the structural position relative to non-rate sensitive liabilities.

TRADED MARKET RISK REVIEW

30 June 2024 compared to 31 December 2023

In H124, there were no significant changes to our traded market risk exposures. The Internal VaR for exposure to traded market risk at 30 June 2024 was less than £1m (2023: less than £1m).

Key metrics

Net Interest Income (NII) sensitivity to +100bps was £119m and to ‑100bps was £(119)m (2023: £220m and £(220)m).

Economic Value of Equity (EVE) sensitivity to +100bps was £(621)m and to ‑100bps was £599m (2023: £(299)m and £265m).

Pension risk

Overview

Pension risk is the risk caused by our statutory contractual or other liabilities with respect to a pension scheme (whether set up for our employees or those of a related company or otherwise). It also refers to the risk that we will need to make payments or other contributions with respect to a pension scheme due to some other reason.

Pension risk management

In H124, there were no significant changes in the way we manage pension risk as described in the 2023 Annual Report.

Pension risk review

In this section, we give an update on key movements in pension risk profile in H124.

PENSION RISK REVIEW

30 June 2024 compared to 31 December 2023

The underlying level of risk in the Scheme reduced during H124, primarily driven by increased interest and inflation hedging and the continuing disposals of illiquid assets, including the sale of some private equity assets.

Risk monitoring and measurement

Our main focus is to ensure the Scheme achieves the right balance between risk and reward whilst minimising the impact on our capital and financial position. At 30 June 2024, the Funding Deficit at Risk decreased to £860m (2023: £980m), mainly due to the hedging noted above with the interest rate hedge ratio at 98% (2023: 89%) and the inflation hedge ratio at 97% (2023: 82%) on a funding basis.

The impact from variations in the IAS 19 position on CET1 capital was not significant in H124. For more on the impact of our defined benefit schemes on capital, see the 'Capital risk' section.

In H124, we adopted a new version of the model that we use to set the IAS19 discount rate. The updated model is based on an expanded data set which is expected to improve the stability of the model. We also updated the mortality improvement assumption we use to value the floating leg of the longevity swap following a mortality basis review carried out by the insurer and the Trustee.

Accounting position

The accounting position deteriorated in H124. The Scheme sections in surplus had an aggregate surplus of £622m at 30 June 2024 (2023: £723m) while there was one section which had a deficit of £6m (2023: £41m). The overall funded position was a £616m surplus (2023: £682m surplus). We reported unfunded liabilities of £24m at 30 June 2024 (2023: £25m). A number of factors caused the position to deteriorate over H124, with notable drivers being rises in gilt yields reducing the value of the assets; a reduction in the value of the longevity swap following a change in the mortality assumption used to value the floating leg; some decreases in return seeking asset values; and deterioration caused by pension increases being higher than expected based on our assumptions. These factors were partially offset by a fall in the liability value, driven by the rise in the gilt yields and an increase in credit spreads, deficit contributions paid over the period, and a change in Scheme actuarial factors following a review by the Trustee. There remains considerable market uncertainty and our position could change materially over a short period.

For more on our pension schemes, including the asset allocation and our accounting assumptions, see Note 23 to the Condensed Consolidated Interim Financial Statements.

Funding Deficit at Risk was £860m (2023: £980m)

Strategic and business risk

Overview

Strategic and business risk is the risk of significant loss or underperformance against planned objectives; damage arising from strategic decisions or their poor implementation; an inability to adapt to external developments that impact the long-term interests of our key stakeholders.

STRATEGIC AND BUSINESS RISK REVIEW

30 June 2024 compared to 31 December 2023

We are in a constantly changing environment, and this impacts the way we do business. The geopolitical uncertainty continued due to the ongoing conflicts in Ukraine and in the Middle East, as well as the outcomes of significant elections around the world. This slowed the pace of economic recovery. We managed our balance sheet in a higher for longer interest rate environment and continued to simplify our operating model, which supports the transformation of our organisation. We proactively reached out to our customers and gave them financial support where needed. We also helped our customers manage their finances by providing them with multiple planning tools and financial health checks.

Our business model is focused on building customer loyalty, through being digital first with a human touch. We made progress in executing our transformation programme with a key focus on improving customer experience, simplifying our products, digitalisation, automation and consolidation of platforms by leveraging the Group's common platforms. We continued to prioritise our customers' needs, underlining our commitment to Consumer Duty.

Our climate ambitions and commitment to managing climate-related impacts are strategically important to our business. So far, we raised and facilitated £15bn of Green Finance against our 2025 target of £20bn. Aligned to our commitment to support our customers, we launched three test and learn propositions. These are a smart heating controls partnership with Tado, a solar partnership with Octopus and an enhanced EPC offering with Vibrant to support our mortgage customers to decarbonise their homes.

Competitive pressures continued in H124, and we saw a renewed focus on Mergers and Acquisition activity with several relevant transactions in the UK banking market in recent months. We remained competitive by launching new products such as our Edge Credit Card which offers cashback, 95% loan to value mortgages for new builds and an improved mobile app for all our retail customers. We grew our business and corporate customers and gave them connections to our global network to support their ambitions of overseas expansion. We continued to invest in our technology to provide a high-quality customer experience.

Overall, we remain focused on securing good customer outcomes, improving efficiency, and building a responsible and sustainable business, while continuing to progress with our agenda to tackle climate change. This will allow us to meet the changing needs of our customers and deliver improved returns over the longterm.

Reputational risk

Overview

Reputational risk is the risk of damage to the way our reputation and brand are perceived by the public, clients, government, colleagues, investors, or any other interested party.

Reputational risk management

In H124, there were no significant changes in the way we manage reputational risk as described in the 2023 Annual Report.

Reputational risk review

In this section, we provide an update on key movements in reputational risk in H124.

REPUTATIONAL RISK REVIEW

30 June 2024 compared to 31 December 2023

In H124, our key reputational risks arose from prolonged cost of living pressures and a changing political landscape. To manage this, we regularly and proactively shared information with key external stakeholders on the actions we took to support customers, colleagues and communities. Particular areas of external focus included our support for customers facing financial difficulties and for mortgage holders.

We also faced significant scrutiny from the UK media on financial crime. To manage this, we responded promptly to enquiries and increased our engagement with key journalists to proactively set our position.

We faced significant reputational risks arising from the Santander global data breach, even though the breach had no material effect on Santander UK. To manage this, we worked closely with colleagues across the Group to develop communications for both external and internal audiences in order to mitigate risks.

In H124, there were no significant changes in the way we manage operational risk as described in the 2023 Annual Report.

Operational risk review

In this section, we give an update on key movements in operational risk in H124.

OPERATIONAL RISK REVIEW

30 June 2024 compared to 31 December 2023

Operational risk event losses

H124 losses remained within our risk appetite. We did not experience any material (greater than £10m) operational risk losses, with the exception of overall fraud losses. We continued to maintain provisions to cover customer remediation programmes and their associated costs.

Business disruption

We continued to address the vulnerabilities identified as part of complying with the Operational Resilience regulatory requirements by March 2025, as described in the 2023 Annual Report. This included embedding resilience through our business disruption response, including communication to our customers and stakeholders. We continued acting on lessons learned from the analysis of live events and severe but plausible scenario tests. We progressed implementation of a target operating model to support operational resilience. The Board approved our last annual operational resilience self-assessment in March 2024 and regularly monitors our progress on enhancing all our operational resilience capabilities.

Cybersecurity

Information and cybersecurity remain a key focus. In H124 we experienced a reportable data breach at one of our suppliers affecting staff personal information. We also responded to a number of other third-party incidents that did not result in notable impacts. We continued to enhance our threat prevention controls and test our business area recovery plans against a range of scenarios. We continued to see increasing ransomware attacks across all sectors, driven by compromises in supply chain tools, and we expect this trend to remain. We continued to invest in the right skills and resources to manage data and cyber risks, and constantly monitor cyber threats, including those from the geopolitical environment.

Data management

In H124, we continued to monitor and mitigate data risk through enhanced governance structures and processes. The key focus is on continuing to build a strong data foundation for the future by prioritising the critical data universe, supported by a new operating model including business process ownership with enhanced focus on end-to-end controls. Our multiyear data programme is delivering in line with the data strategy driven by the Chief Data Officer, with a renewed focus on improving the quality and architecture of the key data underpinning our critical business and regulatory processes.

Fraud

Fraud risk losses remain a material driver of our operational risk loss position, in line with the wider UK financial services industry. Social engineering techniques used by fraudsters are a significant threat to customers and are outside of our controls. Authorised Push Payment (APP) fraud is our largest fraud type, and we focus on preventative measures in response to increasing fraud attacks. In H124, we continued to enhance our preventative capabilities and our controls, including further changes to our dynamic 'scam warnings' in our online banking payment process. We continued to focus on customer education, and a key part of our strategy is presenting customers with tailored questions and warnings specific to their payment journey. We also played a collaborative role in fraud management with industry partners, through UK Finance and Stop Scams UK, alongside our customer awareness campaigns on the most common fraud scams.

IT

The importance of IT remains at the centre of our activities and we continued to progress a bank-wide programme to address key risks in our IT estate, including increasing obsolescence, partly due to the fast pace of technological evolution. We expect the programme to deliver risk reduction over a two-year period and we closely monitor improvements.

Legal

Our legal risk profile remained heightened but broadly stable in H124, reflecting the number and value of legal risks that we continue to manage. We continued to evaluate and respond to the evolving legal and regulatory environment, including the implementation of the Consumer Duty in relation to off-sale products, the introduction of the access to cash regime and APP fraud mandatory reimbursement regime under the Financial Services and Markets Act 2023 and the Digital Markets, Competition and Consumer Act 2024. We expect the new government will introduce new legislation that is likely to impact the Santander UK group's business. We made substantial progress to align material third party contracts to PRA Supervisory Statement 2/21 and to enable international data transfers in line with the Schrems II judgement. While litigated PPI claim volumes remained stable, we continued to prepare for the trial in March 2025 of the on-going large scale complex PPI related litigation brought by AXA and to respond to initiatives by claimant law firms to re-open cases subject to the FCA redress regime for PPI complaints. Litigation, FOS complaints and the FCA review relating to historical motor finance discretionary commission arrangements remained an area of focus. There were no material developments in H124 in relation to the German criminal and tax investigation relating to historical dividend tax arbitrage transactions. We continued to manage our legal risk in relation to thematic Court actions and FOS complaints related to fraud, mortgages and unaffordable lending. For more, see Note 24 to the Condensed Consolidated Interim Financial Statements.

People

People risk continues to be affected by changes in our operating models and the execution of our strategies. We continued to adapt and respond to these risks; in particular, the risks associated with the phased relocation of our Head Office to Unity Place in Milton Keynes, which are under close monitoring and management. H124 continued to show lower levels of wellbeing-related absence. Attrition rates stabilised after periods of successive rises in 2022 reflecting the buoyant job market. We continued to advocate hybrid working and encourage colleagues to attend our offices regularly. We also give support in response to the impact of external economic factors on some colleagues.

Key metrics

Operational risk losses (over £10,000) reduced by 45% compared to H123.

Outsourcing and third party supplier

We continued to rely extensively on third parties for a range of goods and services, provided by both Banco Santander and external suppliers. In H124, we reassessed our major suppliers against a revised set of controls and implemented new metrics to manage our risk exposure.

Transformation and change

We continued our transformation to simplify, digitise processes and customer journeys, reduce costs, extend internal capabilities and ensure a resilient operating model. This includes delivery against a broad transformation agenda with focus on cloud migration, further digitalisation and managing obsolescence. We are also focusing on ensuring transformation and change is safely and sustainably transitioned into business as usual without unacceptable impact on our risk profile underpinning strategic decisions.

FINANCIAL CRIME RISK REVIEW

30 June 2024 compared to 31 December 2023

We take our financial crime responsibilities extremely seriously. Protecting the communities we serve from the social and economic impacts of financial crime remains a top priority. The financial crime landscape continues to be complex, with evolving regulatory and legal requirements, geo-political factors and everchanging criminal methods influencing the risks we face. In H124, we:

  • Continued maturing our financial crime oversight capabilities and our FC Centre of Excellence operations, to further integrate financial crime risk management operations across the business.
  • Maintained Board and Senior management focus on the management of financial crime risk as one of our top priorities, including through the Executive Economic Crime Committee.
  • Updated our financial crime policies and standards to reflect the latest external requirements and best practice, and to align with Banco Santander policy requirements. We supported business areas with implementation guidance.
  • Continuously reviewed our operations and processes to maintain appropriate responses to the fluidity and complexity of global sanctions regimes, deploying supplemental technology in our screening processes.
  • Continued efforts to simplify and digitise customer due diligence processes for new and existing customers.
  • Introduced additional Transaction Monitoring Technology to increase the tools available to us to fight against modern slavery and human trafficking.
  • Improved the data we hold for our customers through our remediation programme.
  • Continued working with the Banco Santander Group to collaborate in sharing best practice and exploring opportunities to leverage its platforms and technologies.
  • Continued to play an active role across the public-private partnerships, working closely with government, trade bodies and industry on issues that may impact our Financial Crime Compliance capabilities. This included extensive work across the sanctions portfolio, such as raising awareness across the Santander UK group and joint work with the UK Government on identifying new risks and sanctions evasion methodologies. It also included horizon scanning and engagement on ongoing and forthcoming legislation and on emerging jurisdictional and sectoral risks we face.
  • Took part in external engagements and responded to key consultations, such as the HM Treasury AML Supervisory Reform and the Money Laundering Regulations, and various Financial Action Task Force consultations.
  • Continued engaging externally on critical strategic public sector documents, such as the implementation of the Economic Crime Plan 2 and Fraud Strategy, forthcoming publications including the new UK National Risk Assessment, and ongoing work on system prioritisation within the economic crime ecosystem.

Model risk

Overview

Model risk is the risk that the predictions from models may be inaccurate, causing sub-optimal decisions to be made; or that a model may be used inappropriately. These potential adverse consequences can lead to reputational damage, regulatory non-compliance, a deterioration in prudential position, or financial losses.

Model risk management

In H124, there were no significant changes in the way we manage model risk as described in the 2023 Annual Report.

Model risk review

In this section, we give an update on key developments in model risk in H124.

MODEL RISK REVIEW

30 June 2024 compared to 31 December 2023

We maintain a risk-based approach to management and control, focusing on model monitoring and independent model reviews of our more material models, such as those for credit losses and those with defined regulatory standards.

We continued work to fully embed requirements relating to the regulations introduced by the PRA in 2023 (Supervisory Statement SS1/23) that increased focus on model risk management across the industry. We carried on developing our regulatory model suite in line with supervisory expectations, focusing on capital adequacy. In H124, we implemented new impairment models for Retail Mortgages and CCB to embed long standing JAs into the models.

As part of our ESG commitment and the overall industry focus, we continued to develop our internal risk models that consider climate change risk factors with longer forecast horizons. We intend to increase internal climate change risk expertise to reduce reliance on our external providers and to continue evolving the models. This allows us to future proof capabilities for future regulation.

As the use of AI tools is increasing within the industry, we continued to develop a robust control environment to support these tools.

CONDUCT AND REGULATORY RISK REVIEW

30 June 2024 compared to 31 December 2023

The Conduct and Regulatory environment continues to see a demanding agenda. To fully consider customer and conduct impacts across our business, our customers remain at the centre of our culture and purpose. We monitor and regularly review our customers' experiences and take action to ensure they receive good outcomes.

As part of this, we:

  • Continued to proactively contact customers who may be at risk of experiencing early signs of financial stress, to try and help them avoid longer term financial difficulty by referring them to internal and external sources of assistance alongside ongoing customer engagement and support plans.
  • Continued to focus on providing financial support for business customers. We continued to further evolve our Financial Support team and support to SMEs, with increased investment in people and IT to ensure we continue to drive good outcomes for customers and can tailor help to our customers, whilst managing the increased inflow of customers affected by cost of living pressures.
  • Delivered a significant number of enhancements of our products and services across the business and support areas to align to the Consumer Duty requirements. These include improving the clarity and understanding of communications, simplifying and digitising customer journeys, and adjusting fees and charges in light of the new fair value requirements. In addition, we have designed, enhanced and implemented the necessary capabilities, processes and tools to further evolve our monitoring and delivery of good customer outcomes.
  • Continued to actively participate in schemes to ensure the long-term future of access to cash, including supporting the set-up of shared banking hubs and wider engagement with LINK and industry partners.
  • Assessed ongoing and new policy areas in the FCA's 2024/25 Business Plan. The FCA's key focus continues to be on reducing and preventing serious consumer harm; setting and testing higher standards; and promoting competition and positive change. We continued to address these in our controls, product and service processes and frameworks, to adapt in line with the evolution of a digital economy.
  • Actively worked with the PSR, UK Finance, Pay.UK and other industry partners, on the PSR's upcoming Mandatory Reimbursement regulations which comes into force in October 2024. Our focus is ensuring consistent standards can be agreed across the industry whilst also ensuring our operational environment will be ready for the implementation date and we are able to meet our obligations.

Like all UK banks, we continued to see a demanding regulatory agenda focused on consumer outcomes and customer vulnerability, including Consumer Duty. We continued to evaluate the evolving regulatory environment, particularly given the Financial Services and Markets Act. Conduct risks will likely continue to rise in the near and medium-term, as banks deal with increasing numbers of personal and business borrowers who are impacted by the rising cost of living under the Consumer Duty framework.

When we implement change, we focus on ensuring that our strategy, leadership, governance arrangements, and approach to managing and rewarding staff does not lead to a detrimental impact on our customers, competition, or to market integrity.

We also remain committed to protecting the personal data we collect and use, and respecting the data protection rights of our customers, our people and others associated with us. Our data protection policy and processes reflect current data protection laws and regulations, and all employees, businesses and third-party suppliers are required to comply with them.

We have reviewed Santander UK plc's condensed consolidated interim financial statements (the "interim financial statements") in the Half Yearly Financial Report of Santander UK plc for the 6 month period ended 30 June 2024 (the "period").

Based on our review, nothing has come to our attention that causes us to believe that the interim financial statements are not prepared, in all material respects, in accordance with UK adopted International Accounting Standard 34, 'Interim Financial Reporting', IAS 34 'Interim Financial Reporting' as issued by the International Accounting Standards Board (IASB) and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority.

The interim financial statements comprise:

  • the Condensed Consolidated Balance Sheet as at 30 June 2024;
  • the Condensed Consolidated Income Statement and the Condensed Consolidated Statement of Comprehensive Income for the period then ended;
  • the Condensed Consolidated Cash Flow Statement for the period then ended;
  • the Condensed Consolidated Statement of Changes in Equity for the period then ended; and
  • the explanatory notes to the interim financial statements.

The interim financial statements included in the Half Yearly Financial Report of Santander UK plc have been prepared in accordance with UK adopted International Accounting Standard 34, 'Interim Financial Reporting', IAS 34 'Interim Financial Reporting' as issued by the International Accounting Standards Board (IASB) and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority.

Basis for conclusion

We conducted our review in accordance with International Standard on Review Engagements (UK) 2410, 'Review of Interim Financial Information Performed by the Independent Auditor of the Entity' issued by the Financial Reporting Council for use in the United Kingdom ("ISRE (UK) 2410"). A review of interim financial information consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures.

A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK) and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

We have read the other information contained in the Half Yearly Financial Report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the interim financial statements.

Conclusions relating to going concern

Based on our review procedures, which are less extensive than those performed in an audit as described in the Basis for conclusion section of this report, nothing has come to our attention to suggest that the directors have inappropriately adopted the going concern basis of accounting or that the directors have identified material uncertainties relating to going concern that are not appropriately disclosed. This conclusion is based on the review procedures performed in accordance with ISRE (UK) 2410. However, future events or conditions may cause the group to cease to continue as a going concern.

Responsibilities for the interim financial statements and the review

Our responsibilities and those of the directors

The Half Yearly Financial Report, including the interim financial statements, is the responsibility of, and has been approved by the directors. The directors are responsible for preparing the Half Yearly Financial Report in accordance with the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority. In preparing the Half Yearly Financial Report, including the interim financial statements, the directors are responsible for assessing the group's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the group or to cease operations, or have no realistic alternative but to do so.

Our responsibility is to express a conclusion on the interim financial statements in the Half Yearly Financial Report based on our review. Our conclusion, including our Conclusions relating to going concern, is based on procedures that are less extensive than audit procedures, as described in the Basis for conclusion paragraph of this report. This report, including the conclusion, has been prepared for and only for the group for the purpose of complying with the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority and for no other purpose. We do not, in giving this conclusion, accept or assume responsibility for any other purpose or to any other person to whom this report is shown or into whose hands it may come save where expressly agreed by our prior consent in writing.

1. ACCOUNTING POLICIES

The financial information in these Condensed Consolidated Interim Financial Statements is unaudited and does not constitute statutory accounts as defined in section 434 of the UK Companies Act 2006. Statutory accounts for the year ended 31 December 2023 have been delivered to the Registrar of Companies.

The Condensed Consolidated Interim Financial Statements reflect all adjustments that, in the opinion of management, are necessary for a fair statement of the results of operations for the interim period. All such adjustments to the financial information are of a normal, recurring nature. Because the results from common banking activities are so closely related and responsive to changes in market conditions, the results for any interim period are not necessarily indicative of the results that can be expected for the year.

The Condensed Consolidated Interim Financial Statements have been prepared in accordance with International Accounting Standard IAS 34 'Interim Financial Reporting', as issued by the International Accounting Standards Board (IASB) and adopted in the UK, and the Disclosure Guidance and Transparency Rules sourcebook of the UK's Financial Conduct Authority (FCA). They do not include all the information and disclosures normally required for full annual financial statements and should be read in conjunction with the Consolidated Financial Statements of Santander UK plc (the Company) and its subsidiaries (collectively Santander UK or the Santander UK group) for the year ended 31 December 2023 which were prepared in accordance with UK-adopted International Accounting Standards (IAS). Those consolidated financial statements were also prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the IASB, including interpretations issued by the IFRS Interpretations Committee, as there were no applicable differences from IFRS as issued by the IASB for the periods presented.

The same accounting policies, presentation and methods of computation are followed in these Condensed Consolidated Interim Financial Statements as were applied in the presentation of the Santander UK group's 2023 Annual Report.

Future accounting developments

The IASB issued the following new/amended accounting standards which are not yet effective and have not been endorsed for use in the UK:

  • Effective 1 January 2026: 'Amendments to the Classification and Measurement of Financial Instruments' (Amendments to IFRS 9 'Financial Instruments' and IFRS 7 'Financial Instruments: Disclosures') - the amendments set out changes to settling financial liabilities using an electronic payment system, assessing contractual cash flow characteristics of financial assets including those with environmental, social and governance (ESG)-linked features and requiring additional disclosures for certain financial instruments.
  • Effective 1 January 2027: IFRS 18 'Presentation and Disclosure in Financial Statements' the new standard will replace IAS 1 'Presentation of Financial Statements' and introduces changes to the categories for classifying income and expenses and subtotals presented in the income statement and new or amended disclosures in respect of management-defined performance measures and specified expenses by nature.

The Santander UK group is assessing these new/amended accounting standards to determine the potential impacts on the financial statements when they become effective or if they are otherwise earlier adopted when available.

Going concern

In light of geopolitical and economic uncertainty, the Directors updated their going concern assessment in preparing these Condensed Consolidated Interim Financial Statements. In making their going concern assessment, the Directors considered a wide range of information that included Santander UK's long term business and strategic plans, forecasts and projections, estimated capital, funding and liquidity requirements, contingent liabilities and the reasonably possible changes in trading performance arising from potential economic, market and product developments.

After making enquiries, the Directors have a reasonable expectation that Santander UK has adequate resources to continue in operational existence for at least twelve months from the date of this report and, therefore, having reassessed the principal risks and uncertainties, the Directors consider it appropriate for the Condensed Consolidated Interim Financial Statements to be prepared on a going concern basis.

Critical judgements and accounting estimates

The preparation of Santander UK's condensed consolidated financial statements in accordance with IFRS requires management to make judgements and assumptions in applying the accounting policies that affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based on amounts which differ from those estimates. Estimates, judgements and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

There has been no change in the inherent sensitivity of the areas of judgement in the period. Management have considered the impact of developments in principal risks and uncertainties, as set out in the Risk review, on critical judgements and accounting estimates.

The significant judgements, apart from those involving estimation, made by management in applying Santander UK's accounting policies in these financial statements (key judgements) and the key sources of estimation uncertainty that may have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities within the next financial year (key estimates), which together are considered critical to Santander UK's results and financial position, are as follows:

a) Credit impairment allowance

Key judgements – Determining an appropriate definition of default
– Establishing the criteria for a significant increase in credit risk (SICR) and, for corporate borrowers, internal credit risk rating
– Determining the need for any judgemental adjustments
– Determining the need to assess corporate Stage 3 exposures individually
Key estimates – Forward-looking multiple economic scenario assumptions
– Probability weights assigned to multiple economic scenarios

For more on each of these key judgements and estimates, see 'Critical judgements and accounting estimates applied in calculating ECL' in the 'Credit risk – credit risk management' section of the Risk review in the 2023 Annual Report.

Sensitivity of ECL allowance

For detailed disclosures, see 'Sensitivity of ECL allowance' in the 'Credit risk – credit risk management' section of the Risk review.

Directors Financial Shareholder
CEO review Financial overview responsibilities Risk review statements information

b) Provisions and contingent liabilities

Key judgements – Determining whether a present obligation exists
– Determining the likely outcome of future legal decisions
Key estimates – Probability, timing, nature and amount of any outflows that may arise from past events

Included in Litigation and other regulatory provisions in Note 22 are amounts in respect of management's best estimates of liability relating to a legal dispute regarding allocation of responsibility for a specific PPI portfolio of complaints, and Plevin related litigation. Note 24 provides disclosure relating to ongoing factual issues and reviews that could impact the timing and amount of any outflows. It includes disclosure relating to an investigation in relation to the historical involvement of Santander UK plc, Santander Financial Services plc and Cater Allen International Limited (all subsidiaries of Santander UK Group Holdings plc) in German dividend tax arbitrage transactions. It also includes disclosure relating to the historical use of discretionary commission arrangements by Santander Consumer (UK) plc.

These judgements are based on the specific facts available and often require specialist professional advice. There can be a wide range of possible outcomes and uncertainties, particularly in relation to legal actions, and regulatory and consumer credit matters. As a result, it is often not possible to make reliable estimates of the likelihood and amount of any potential outflows, or to calculate any resulting sensitivities. For more on each of these key judgements and estimates, see Notes 22 and 24.

c) Retirement benefit plans

– Setting the criteria for constructing the corporate bond yield curve used to determine the discount rate
– Determining the methodology for setting the inflation assumption
– Discount rate applied to future cash flows
– Rate of price inflation
– Expected lifetime of the schemes' members
– Valuation of pension fund assets whose values are not based on market observable data

For more on each of these key judgements and estimates, see Note 23.

Sensitivity of defined benefit pension scheme estimates

For detailed disclosures, see 'Actuarial assumption sensitivities' in Note 23.

The Scheme is invested in certain assets whose values are not based on market observable data, such as investments in private equity funds and property. Due diligence has been conducted to support the values obtained in respect of these assets represent fair value. Given the nature of these investments, we are unable to prepare sensitivities on how their values could vary as market conditions or other variables change.

d) Goodwill

Key judgements: – Determining the basis of goodwill impairment testing methodology, including the need for planning assumptions and internal capital allocations
– Identifying the indicators of potential impairment
Key estimates: – Forecast cash flows for cash generating units, including estimated allocations of regulatory capital
– Growth rate beyond initial cash flow projections
– Discount rates which factor in risk-free rates and applicable risk premiums
All of these variables are subject to fluctuations in external market rates and economic conditions beyond management's control

For more on each of these key judgements and estimates, see Note 14.

Sensitivity of goodwill

For detailed disclosures, see 'Sensitivities of key assumptions in calculating VIU' in Note 20 to the Consolidated Financial Statements in the 2023 Annual Report.

2. SEGMENTS

Santander UK's principal activity is financial services, mainly in the UK. The business is managed and reported on the basis of four segments, which are strategic business units that offer different products and services, have different customers and require different technology and marketing strategies.

The table below shows the relationship between Customer assets and Loans and advances to customers as presented in the Condensed Consolidated Balance Sheet. Customer assets exclude Joint ventures, as they carry low credit risk and therefore have an immaterial ECL, and Other items, mainly accrued interest that we have not yet charged to the customer's account and cash collateral. It also shows the relationship between customer liabilities (see above) and Deposits by customers as presented in the Condensed Consolidated Balance Sheet.

Net provisions of £6m were recognised in H124 for customer remediations, relating to our mortgage book. The provisions remain subject to change as additional data becomes available and remediation boundaries are finalised.

Litigation and other regulatory provisions principally comprised amounts in respect of litigation and other regulatory charges, operational loss and operational risk provisions, and related expenses. A number of uncertainties exist with respect to these provisions given the uncertainties inherent in litigation and other regulatory matters, that affect the amount and timing of any potential outflows with respect to which provisions have been established. These provisions are reviewed at least quarterly.

In H124 there were charges of £4m for legal provisions. The balance also includes an amount in respect of our best estimate of liability relating to legal dispute regarding allocation of responsibility for a specific PPI portfolio of complaints, further described in Note 24. No further information on the best estimate is provided on the basis that it would be seriously prejudicial.

Regulatory levies and fees are payable to regulatory bodies such as the FCA, PRA and Bank of England in the ordinary course of business. In H124 there were charges of £37m relating to the new Bank of England levy.

In H124, other provisions included charges for operational risk provisions of £71m (H123: £87m), including fraud losses of £54m (H123: £75m).

a) Defined contribution pension plans

An expense of £40m (H123: £33m) was recognised for defined contribution plans in the period and is included in staff costs within operating expenses (see Note 3).

b) Defined benefit pension schemes

The total amount charged to the income statement was £6m (H123: charge of £16m).

The amounts recognised in other comprehensive income were as follows:

Actuarial assumptions

The principal actuarial assumptions used for the Scheme were:

30 June 2024 31 December 2023
% %
To determine benefit obligations(1)
:
– Discount rate for scheme liabilities 5.2 4.6
– General price inflation 3.1 3.0
– General salary increase 1 1.0
– Expected rate of pension increase 2.9 3.0
Years Years
Longevity at 60 for current pensioners, on the valuation date:
– Males 27.1 27.0
– Females 29.8 29.8
Longevity at 60 for future pensioners currently aged 40, on the valuation date:
– Males 28.7 28.6
– Females 31.4 31.3

(1) The discount rate and inflation related assumptions set out in the table above reflect the assumptions calculated based on the Scheme's duration and cash flow profile as a whole. The actual assumptions used were determined for each section independently based on each section's duration and cash flow profile.

The majority of the liability movement in H124 was due to increased fixed interest gilt yields.

In H124, we adopted a new version of the model that we currently use to set the discount rate. The updated model is based on an expanded data set which improves stability of the model.

Actuarial assumption sensitivities

The sensitivity analyses below have been determined based on reasonably possible changes of the respective assumptions occurring at the end of the reporting period, while holding all other assumptions constant.

(Decrease)/increase
30 June 2024 31 December 2023
Assumption Change in pension obligation at period end from £m £m

Other legal, regulatory or tax matters

Santander UK engages in discussion, and co-operates, with the FCA, PRA, CMA and other regulators and government agencies in various jurisdictions in their supervision and review of Santander UK including reviews exercised under statutory powers, regarding its interaction with past and present customers, both as part of general thematic work and in relation to specific products, services and activities. During the ordinary course of business, Santander UK is also subject to complaints and threatened legal proceedings brought by or on behalf of current or former employees, customers, investors or other third parties. In addition, Santander UK is subject to audits, reviews, challenges and tax, regulatory or law enforcement investigations or proceedings by relevant regulators or government agencies in various jurisdictions. All such matters are assessed periodically to determine the likelihood of Santander UK incurring a liability.

In those instances where it is concluded that it is not yet probable that a quantifiable payment will be made, for example because the facts are unclear or further time is required to fully assess the merits of the case or to reasonably quantify the expected payment, no provision is made. In addition, where it is not currently practicable to estimate the possible financial effect of these matters, no provision is made.

Payment Protection Insurance

AXA France IARD and AXA France Vie (former GE Capital Corporation Group entities (GE Capital), known as Financial Insurance Company Ltd (FICL) and Financial Assurance Company Ltd (FACL), acquired by AXA SA in 2015) (together, AXA France) have brought a claim for £552m (plus interest) against (i) Santander Cards UK Limited (former GE Capital entity known as GE Capital Bank Limited (GECB), which was acquired by Banco Santander SA in 2008 and subsequently transferred to Santander UK plc); and (ii) Santander Insurance Services UK Limited (a Banco Santander SA subsidiary) (together the Santander Entities). The claim relates to the allocation of liability for compensation and associated costs in respect of a large number of PPI policies distributed by GECB pre-2005, which were underwritten by FICL and FACL. AXA France reduced their claim from £670m (plus interest) to £552m (plus interest) in their Re-Re-Amended Particulars of Claim dated 29 June 2023. The Santander Entities strongly refute the claim. Trial has been fixed for six weeks, beginning on 3 March 2025.

There are ongoing factual issues to be resolved which may have legal consequences including in relation to liability. These issues create uncertainties which mean that it is difficult to reliably predict the outcome or the timing of the resolution of the matter. The litigation and other regulatory provision in Note 22 includes our best estimate of the Santander Entities' liability to the specific portfolio. Further information has not been provided on the basis that it would be seriously prejudicial to the Santander Entities' interests in connection with the dispute.

In addition, and in relation to PPI more generally, the PPI provision includes an amount relating to legal claims challenging the FCA's industry guidance on the treatment of Plevin / recurring non-disclosure assessments. This provision is based on current stock levels, future projected claims, and average redress. There remains a risk that volumes received in future may be higher than forecast. The provision in Note 22 includes our best estimate of Santander UK's liability for the specific issue. The actual cost of customer compensation could differ from the amount provided. It is not currently practicable to provide an estimate of the risk and amount of any further financial impact.

German dividend tax arbitrage transactions

In June 2018 the Cologne Criminal Prosecution Office and the German Federal Tax Office commenced an investigation in relation to the historical involvement of Santander UK plc, Santander Financial Services plc and Cater Allen International Limited (all subsidiaries of Santander UK Group Holdings plc) in German dividend tax arbitrage transactions (known as cum/ex transactions). These transactions allegedly exploited a loophole of a specific German settlement mechanism through short-selling and complex derivative structuring which resulted in the German government either refunding withholding tax where such tax had not been paid or refunding it more than once. The German authorities are investigating numerous institutions and individuals in connection with alleged transactions and practices which may be found to be illegal under German law.

During H124 we continued to cooperate with the German authorities and, with the assistance of external experts, to progress an internal investigation into the matters in question. From Santander UK plc's perspective, the investigation is focused principally on the period 2009-2011 and remains on-going. There remain factual issues to be resolved which may have legal consequences including potentially material financial penalties. These issues create uncertainties which mean that it is difficult to predict the resolution of the matter including timing or the significance of the possible impact. These uncertainties mean it is not currently practicable to make a reliable assessment of the size of any related potential liability. Any potential losses, claims or expenses suffered or incurred by Santander Financial Services plc in respect of these matters have been fully indemnified by Santander UK plc, as part of the ring-fencing transfer scheme between Santander UK plc, Santander Financial Services plc and Banco Santander SA.

SCUK - Motor Finance Broker Commissions

Following the FCA's Motor Market review in 2019 which resulted in a change in rules in January 2021, Santander Consumer (UK) plc (SCUK) has received a number of county court claims and complaints in respect of its historical use of discretionary commission arrangements (DCAs) prior to the 2021 rule changes. In the context of the complaints made to the Financial Ombudsman Service relating to such commission arrangements, the FCA commenced in January a review of the use of DCAs between lenders and credit brokers (the FCA review). A claim has also been issued against SCUK, Santander UK plc and others in the Competition Appeal Tribunal (CAT), alleging that SCUK's historical commission arrangements in respect of used car financing operated in breach of the Competition Act 1998. In July 2024, the FCA extended the timeline for its review to May 2025 and proposed an extension of the current pause on complaints handling related to discretionary commission arrangements from September 2024 to 4 December 2025. While it is possible that certain charges may be incurred in relation to the FCA's review or related existing or future county court claims, Financial Ombudsman Service (FOS) complaints and the Competition Appeal Tribunal (CAT) proceedings, it is not considered that a legal or constructive obligation has been incurred in relation to these matters that would require a provision to be recognised at this stage. The resolution of such matters is not possible to predict with any certainty and there remain significant inherent uncertainties regarding the existence, scope and timing of any possible outflow which make it impracticable to disclose the extent of any potential financial impact.

Other

On 2 November 2015, Visa Europe Ltd agreed to sell 100% of its share capital to Visa Inc. The deal closed on 21 June 2016. As a member and shareholder of Visa Europe Ltd, Santander UK received upfront consideration made up of cash and convertible preferred stock. Conversion of the preferred stock into Class A Common Stock of Visa Inc. depends on the outcome of litigation against Visa involving UK & Ireland multilateral interchange fees (UK&I MIFs). The convertible preferred stock is now held by Santander Equity Investments Limited (SEIL), outside the ring-fenced bank.

In addition, Santander UK plc and certain other UK&I banks have agreed to indemnify Visa Inc. in the event that the preferred stock is insufficient to meet the costs of this litigation. Visa Inc. has recourse to this indemnity once more than €1bn of losses relating to UK&I MIFs have arisen or once the total value of the preferred stock issued to UK&I banks on closing has been reduced to nil. Santander UK plc's liability under this indemnity is capped at €39.85m. At this stage, it is unclear whether the litigation will give rise to more than €1bn of losses relating to UK&I MIFs which means it is not practicable to predict the resolution of the matter including the timing or the significance of the possible impact.

As part of the sale of subsidiaries, businesses and other entities, and as is normal in such circumstances, entities within the Santander UK group have given warranties and/or indemnities to the purchasers.

Securitisations and covered bonds

As described in Note 14, to the Consolidated Financial Statements in the 2023 Annual Report, Santander UK plc and certain of its subsidiaries issue securitisations and covered bonds through or involving structured entities. At 30 June 2024, there were £33,189m (2023: £27,927m) of gross assets in these secured programmes and £1,637m (2023: £839m) of these related to internally retained issuances that were available for use as collateral for liquidity purposes in the future.

At 30 June 2024, £3,753m (2023: £2,928m) of notes issued under securitisation and covered bond programmes had been retained internally, a proportion of which had been used as collateral via third party bilateral secured funding transactions, which totalled £1,500m at 30 June 2024 (2023: £1,500m), or for use as collateral for liquidity purposes in the future.

27. RELATED PARTY DISCLOSURES

Related party transactions in the period were similar in nature to those in Note 38 to the Consolidated Financial Statements in the 2023 Annual Report. The financial position and performance of the Santander UK group were not materially affected in H124 by any related party transactions, or changes to related party transactions, other than as disclosed herein.

d) Valuation techniques

The main valuation techniques employed in internal models to measure the fair value of the financial instruments are disclosed in Note 39(b) to the Consolidated Financial Statements in the 2023 Annual Report.

e) Fair value adjustments

The internal models incorporate assumptions that Santander UK believes would be made by a market participant to establish fair value. Fair value adjustments are adopted when Santander UK considers that there are additional factors that would be considered by a market participant that are not incorporated in the valuation model.

Santander UK classifies fair value adjustments as either 'risk-related' or 'model-related'. The fair value adjustments form part of the portfolio fair value and are included in the balance sheet values of the product types to which they have been applied.

The fair value adjustments are set out in the following table:

30 June 2024 31 December 2023
£m £m
Risk-related:
- Bid-offer and trade specific adjustments 8 (6)
- Uncertainty 5 6
- Credit risk adjustment 1
- Funding fair value adjustment 1
13 2
Day One profit 1 1
14 3

Risk-related adjustments

Risk-related adjustments are driven, in part, by the magnitude of Santander UK's market or credit risk exposure, and by external market factors, such as the size of market spreads. For more details, see 'Risk-related adjustments' in Note 39(f) to the Consolidated Financial Statements in the 2023 Annual Report.

f) Internal models based on information other than market data (Level 3)

Valuation techniques

There have been no significant changes to the valuation techniques as set out in Note 39(g) to the Consolidated Financial Statements in the 2023 Annual Report.

Forward-looking statements

The Company and its subsidiaries (together Santander UK) may from time to time make written or oral forward-looking statements. The Company makes written forward-looking statements in this Half Yearly Financial Report and may also make forward-looking statements in its periodic reports to the SEC on Forms 20-F and 6-K, in its offering circulars and prospectuses, in press releases and other written materials and in oral statements made by its officers, directors or employees to third parties.

By their very nature, forward-looking statements are not statements of historical or current facts; they cannot be objectively verified, are speculative and involve inherent risks and uncertainties, both general and specific, and risks exist that the predictions, forecasts, projections and other forward-looking statements will not be achieved. Santander UK cautions readers that a number of important factors, could cause actual results to differ materially from the plans, objectives, expectations, estimates and intentions expressed in such forward-looking statements made by Santander UK or on its behalf. For more, see 'Forward-looking statements' in the Shareholder information section of the 2023 Annual Report.

Please also refer to our latest filings with the SEC (including, without limitation, our Annual Report on Form 20-F for the year ended 31 December 2023) for a discussion of certain risk factors and forward-looking statements. Undue reliance should not be placed on forward-looking statements when making decisions with respect to any Santander UK member and/or its securities. Investors and others should take into account the inherent risks and uncertainties of forwardlooking statements and should carefully consider the non-exhaustive list of important factors in the 2023 Annual Report, and how it could affect our operations and financial position. Forward-looking statements speak only as of the date on which they are made and are based on the knowledge, information available and views taken on the date on which they are made; such knowledge, information and views may change at any time. Santander UK does not undertake any obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.
