This is a list of the world's largest United Kingdom-based law firms by revenue in the financial year 2024. This data is based on the law firms official financial report for the 2023/24 financial year running from 1 April 2023 to 31 March 2024. The list contains the 17 law firms which generated over half a billion US dollars in this period. 16 of which are London-based and 1 headquarter in Manchester.
Note: A few UK based law firms have merged with another entity which may be located outside of the UK for example London's Allen & Overy merged with New York's Shearman in May of 2024, the result of this is the removal of the US revenue and number of lawyers from the list to just account for its UK operations. As well as this some data from the number of lawyers at the firms are from the 2022/23 financial year as the firms have not updated as of 12/01/25.
