National law firm TLT grew revenue 7.5% in the past financial year to £187m, the latest UK firm to report record results so far this reporting season.
Growth during the year to 31 March 2025 marked a slowdown on the previous year’s 12% gain but nonetheless means TLT has added more than £75m to its topline over the past four years. The firm does not disclose profits or profit per equity partner.
John Wood, TLT’s managing partner, said: “Reaching £187m in revenue reflects the extraordinary commitment, talent and ambition of our people, and the trust our clients place in us. We continue to grow and make significant investments to deliver a long-term growth strategy, whilst also staying true to our values, whether that’s leading the way in future energy, driving innovation through technology or playing a central part in building a more inclusive and sustainable legal sector.”
The firm attributed that performance to making significant partner hires and expanding its national office footprint, including moving into a new office in Edinburgh that doubled its space in the city.
It has now grown its total headcount to more than 1,800, with 12 partner additions during that period, including eight partners that joined from BDB Pitmans alongside 21 associates to create one of the largest future energy, infrastructure and planning practices. The firm said it now had more than 150 specialists in this space, positioning it as one of the leading legal advisers within the UK’s energy transition.
In March, TLT promoted three female lawyers to partner in a seven-strong round and launched a new target for women to hold half of all partner positions by 2029, having hit its target to reach 33% representation two years ahead of schedule.
In addition to its gender equality plans, TLT has also been seeking to improve the proportion of lawyers from under-represented groups by teaming up with organisations including My Big Career in London and Ablaze in Bristol. Last year the firm set a target to achieve 35% ethnic minority representation across its early career roles by October 2030, increasing the proportion from one in five to one in three. TLT was ranked 39th on the 2024 Social Mobility Index, up from 47th place in 2023.
The revenue jump was also attributed to its project work for central and local government and advice on energy initiatives. Standout client work included acting for the UK government in the recent UK India free trade deal and settling a phone hacking claim against MGN Limited.
The firm also won a place on BT Group’s legal panel and was reappointed to the National Legal Services Framework, while on the energy side TLT advised on the completion of 40 renewable energy projects, including acting for Thrive Renewables on its acquisition of the 57MW Whitelaw Brae windfarm.
Wood added: “As we look ahead, we remain focused on creating meaningful growth opportunities for our clients, whilst delivering a progressive workplace with a market-leading culture, underpinned by sustainability.”
