This list comprises banks operating in the United Kingdom that are authorised and prudentially regulated by the Prudential Regulation Authority (PRA), a part of the Bank of England. The PRA is responsible for the prudential supervision of financial firms that manage significant risks on their balance sheets, including banks, building societies, credit unions, and insurers. Its primary objective is to promote the safety and soundness of these institutions, thereby contributing to the financial stability of the UK.
The banks on this list include both UK-incorporated banks (often referred to as 'local' banks) and non-UK banks that have established a presence in the UK.
Banks UK banks According to data from the UK Prudential Regulation Authority (PRA), as of July 2025, there are 150 locally incorporated banks in the UK, with several banking groups holding multiple banking licences.
Total assets This table ranks banking entities registered in the United Kingdom based on their consolidated total assets as of the latest available financial data from 2024 through Q1 2025. The rankings are based solely on the size of UK-registered bank entities and may include the asset contributions of overseas branches that form part of the same UK-registered legal entity.
+ Regulated UK-banks ranked by consolidated total assets (2024 - 2025 Q1)Notes:‡: The registered banking entity holds multiple domestic and international legal entities with substantial assets. Accordingly, its financial statements reflect the full consolidation of controlled subsidiaries—typically defined as those where the bank holds more than 50% of voting rights—in compliance with International Financial Reporting Standard 10 (IFRS 10): Consolidated Financial Statements.§: The reported figures are based on combined estimates for the local bank under the same holding group; these data are intended for indicative comparison purposes only.RankBank nameTotal assets (£m)1Barclays§1,518,202Barclays Bank‡1,218,524Barclays Bank UK303,1792HSBC§1,068,207HSBC Bank‡727,330HSBC Innovation Bank9,635HSBC UK Bank‡340,877HSBC Private Bank (UK)7.135Marks & Spencer Financial Services4,710.133Lloyds§906,697Lloyds Bank611,213Bank of Scotland331,084Lloyds Bank Corporate Markets‡94,9724NatWest§707,985National Westminster Bank424,309The Royal Bank of Scotland90,476Coutts & Company62,860NatWest Markets‡183,1665J.P.
