The legal arm of Deloitte has boosted its revenue in the U.K. by over a fifth, according to people with knowledge of the professional services firm.

In its U.K. firmwide results announced last week, revenue for Deloitte’s wider tax and legal business was given as £1.21 billion in the 12 months to May 2023—which represents growth of 9% on last year. However, Deloitte Legal has seen revenue growth of over twice this percentage, at a rate that is higher than the vast majority of U.K. Top 50 firms in the last financial year.
