Pinsent Masons has unveiled a £100,000 jump in profits per equity partner (PEP) as the top 20 UK law firm becomes the latest to reveal its financial results for the 2009-10 financial year.

Pinsents' profits increased by 32% to £410,000 over the last financial year, up from £310,000 during the 2008-09.

Meanwhile turnover dipped 4% from £215m in 2008-09 to £206m for the last financial year.

International arbitration; restructuring; pensions and outsourcing; and technology & commercial were all high-performing areas. The firm also pointed to its operations in the Gulf as a strong performer.

Pinsents managing partner David Ryan commented: "Our results reflect a spirited and determined performance by everyone in the business. In a tough climate, we not only made real progress but also made some important, strategic investments – particularly in life sciences and Islamic finance – which augur well for this year."

He added: "We are confident that there is more progress to be made this year, along with sizeable investment in our major new London HQ."

The announcement comes after a number of national firms posted their financial results last week, with Weightmans and HBJ Gateley Wareing both seeing increases in revenues for the year, with the former announcing an 8.1% rise in turnover to £56.2m while the latter saw fee income increase by 5.3% to £49.6m.
