TLT breaks £200m revenue barrier

National law firm TLT has announced another record-breaking year of financial results, with the firm achieving 11% revenue growth and hitting £208m in 2025/26 – doubling revenue over the last five years.

The firm’s continued growth is driven by its commitment to creating opportunity, for its clients and people, through innovation, collaboration and shared values, which sees it consistently winning market share and panel positions.

TLT invested significantly in people and places over the last year, welcoming 22 new partners across the firm’s locations and eight core sectors, including eight partners in London as part of a 29 strong team – creating the largest legal practice dedicated to public law, infrastructure planning and future energy in the UK. The firm also promoted seven colleagues to partner in 2025.

Investment continued in the firm’s market leading FutureLaw team – dedicated to enhancing legal services through driving digital transformation – which also doubled in headcount. Trailblazers in innovation, TLT announced a partnership with and firmwide roll-out of legal AI workspace Legora, and launched a new business ready AI solution, TLT Intelligence, bringing together the best of the firm’s AI tools, AI expertise, and AI-powered legal services in three flexible ways to empower clients to accelerate their adoption of technology, creating real business value.  

TLT's substantial growth is steeped in advising clients on significant transactions, regulatory scrutiny, high profile investigations and complex litigation and in addition the firm won places on several high-profile panels across both public and private sector, among them: Government Commercial Agency’s Legal Panel for Government framework, National Grid, National Legal Services Framework, SSE and Transport for London.

The firm’s deeply embedded commitment to sustainability was evidenced through its standout Future Energy sector, future-proofed premises, and the launch of a carbon offsetting partnership with Belmont Estate. TLT achieved a transformative 93% reduction in Scope 1 and 2 (market-based) greenhouse gas emissions compared to a FY2019 baseline, surpassing its 2030 goal six years ahead of schedule. The firm was awarded B’ score for good environmental management for the fourth consecutive year, from CDP; and a Silver rating from EcoVadis. 

Other notable strategic, values-driven, partnership success included launching a new ‘Beyond Boundaries’ school leaver work experience programme in collaboration with The Black Apprentice Network and being among the first UK law firms to sign up to a new employer support programme spearheaded by leading Women's Health Charity‚ Wellbeing of Women.

John Wood, TLT Managing Partner, said: “We’re proud to deliver double digit growth, testament to the commitment, creativity and collaboration demonstrated by our people in a challenging market, innovating to unlock opportunities for our clients and organisation. 

"TLT is on an exciting growth trajectory, breaking through the £200m million mark is a significant milestone in our journey and we are confident we will exceed £300m by 2030. But that’s not the TLT2030 strategy, it’s the consequence of the strategy. What is a more interesting question for us and what we are focussing on is defining and delivering what a successful law firm looks like in 2040.

“Our ambition is not simply to be a bigger version of today’s TLT. It’s to build a firm that is recognised for combining legal expertise, technology, data and sector insight in ways that clients value whilst preserving and enhancing the culture we value so much. You get that right and the numbers take care of themselves.”
