Gilson Gray has been officially recognised as the fastest-growing law firm in the UK, according to the latest UK Fast Growth Index.
The full-service firm ranked as the 15th fastest-growing professional services business overall, securing the highest position of any legal sector organisation.
Gilson Gray reported revenues of more than £32million for its 2023-2024 financial year. Between 2024 and 2025, the firm has delivered £40million of turnover (a 25% year on year increase), and based on the first half of the 2025-26 financial year, expectation is to break £50million in revenue (a further 20% growth year on year), consolidating the law firm's position as a leading light in UK legal sector growth.
The achievement follows a string of significant industry accolades, including Law Firm of the Year at The Herald Law Awards of Scotland 2025, Leading Firm - Legal 500, managing partner of the year, shortlisted CEO of the year and several more.

The firm’s momentum is being fuelled by a series of strategic senior appointments across its London and Lincoln offices. Recent hires include Jeremy Davy, who joined as partner and head of residential conveyancing for England and Wales, and Steven Eckett, who becomes head of employment for England.
Now employing close to 500 people and operating from offices in London, Edinburgh, Glasgow, Dundee, East Lothian, Aberdeen, Lincoln, and Angus, Gilson Gray continues its nationwide expansion while retaining the agility, culture, and client-first approach that define the firm.
Glen Gilson, chairman and managing partner at Gilson Gray, said: “We are immensely proud to be recognised as the fastest-growing law firm in the UK. This ranking reflects the talent, drive, and dedication of our people, as well as the continued trust of our clients. Our integrated model enables us to deliver exceptional legal, property, and financial services under one roof, and this national recognition reinforces the success of that strategy as we continue our growth across the UK.”
