United Kingdom listed companies.

1,517 publicly traded British companies, organised by sector and exchange. Each company links into its filings history, KPIs and reporting metadata.

Public-company filings in United Kingdom are supervised by Financial Conduct Authority (FCA). Reporting follows UK-adopted IAS / IFRS (listed); UK GAAP / FRS 102 (others). Filings are most commonly published in English. Major issuers are listed on FTSE 100, FTSE 250 and FTSE 350. Mixed — calendar, March, and April year-ends common.

The UK listed-company universe — Main Market and AIM

The UK is the deepest equity market in Europe by listed count: roughly 1,800 companies trade on the London Stock Exchange across the regulated Main Market (Premium and Standard segments) and the SME-focused AIM growth segment. The headline indices — FTSE 100, FTSE 250, FTSE 350, FTSE SmallCap, and the AIM-tilted FTSE AIM 100 — segment the universe by free-float market cap and venue.

The FTSE 100 is global by revenue mix: roughly 75% of constituent revenue is earned outside the UK, with energy supermajors (Shell, BP), pharma (AstraZeneca, GSK), financials (HSBC, Barclays, Lloyds, Standard Chartered), consumer staples (Unilever, Reckitt, Diageo), miners (Rio Tinto, Glencore, Anglo American), and tech (Sage, RELX) anchoring the index. The FTSE 250 is more domestically tilted and more diverse, with strong representation in financials, real estate, industrials, and consumer-cyclicals. AIM hosts a long tail of growth-stage issuers in technology, biotech, and natural resources, with lighter listing requirements but full RNS / DTR disclosure obligations.

FinancialReports tracks every Main Market and AIM-listed issuer, classified by FRCF / ISIC sector, industry group, and listing segment. Sector composition skews toward Financials (~20%), Energy and Materials (high relative to European peers due to the FTSE 100 mega-caps), Consumer Staples, Healthcare, and Industrials. Each company page surfaces complete filings history, ISINs, multiple ticker / SEDOL codes, dual-listings (most prominently on US exchanges), and IR metadata, refreshed daily.

The UK universe also captures one of the highest IPO and de-listing throughputs in Europe, which the platform handles natively — new admissions appear with their first RNS already indexed, de-listings preserve the historical archive for backtesting, and segment migrations (AIM-to-Main, Premium-to-Standard) flow through the same ingestion pipeline.
