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.
A few UK-based law firms have merged with another entity which may be located outside of the UK. For example, Allen & Overy (London) merged with Shearman (New York) in May 2024; the result of this is the removal of the US revenue and number of lawyers from the list to account for its UK operations. 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 January 2025. + Largest United Kingdom–based law firms Firm Revenue (US$) Number of practising Lawyers Revenue per Lawyer Headquartered Clifford Chance $2.810 billion 3,319 $846,641 London, England Linklaters $2.730 billion 3,075 $887,805 London, England Allen & Overy $2.690 billion 3,358 $801,073 London, England Freshfields Bruckhaus Deringer $2.550 billion 2,038 $1,251,227 London, England Herbert Smith Freehills Kramer $1.594 billion 2,299 $693,345 London, England Ashurst LLP $1.173 billion 1,719 $682,373 London, England Clyde & Co $1.043 billion 2,138 $487,839 London, England Eversheds Sutherland $0.915 billion 2,616 $349,770 London, England Bryan Cave Leighton Paisner $0.840 billion 1,275 $658,824 London, England Slaughter and May $0.805 billion 594 $1,355,219 London, England Pinsent Masons $0.793 billion 2,330 $340,343 London, England Simmons & Simmons $0.701 billion 974 $719,713 London, England Bird & Bird $0.665 billion 1,600 $415,625 London, England Addleshaw Goddard $0.606 billion 1,197 $506,267 London, England Taylor Wessing $0.587 billion 1,179 $497,880 London, EnglandOsborne Clarke$0.543 billion1,205$450,622London, England DWF $0.531 billion 1,100 $482,727 Manchester, England
