What TLT does

TLT LLP is a UK national law firm structured as a limited liability partnership, headquartered in London and operating from seven UK offices — Bristol, Belfast, Birmingham, Edinburgh, Glasgow, London, and Manchester — with an international affiliate in Piraeus, Greece. The firm is organised around eight sector verticals (Digital, Financial Services, Future Energy, Government & Public Services, Infrastructure, Leisure/Food & Drink, Real Estate, and Retail & Consumer Goods) and a broad set of legal practices including Corporate, Banking & Finance, Employment, Data Privacy & Cybersecurity, Dispute Resolution, Planning, Intellectual Property, Restructuring & Insolvency, Tax, and Public Inquiries & Public Law. Revenue is generated through partner-led professional legal services on billable-hour, fixed-fee, and project-based pricing structures across enterprise and public-sector clients.

The firm differentiates through sector specialisation, claiming the UK's largest public law, infrastructure planning, and future energy legal team, and through its FutureLaw initiative, which encompasses TLT Intelligence (an AI-focused platform to accelerate enterprise AI adoption), managed legal services, legal project management, and contract automation (e.g., a documented 75% contract drafting-time reduction for waste-management client Biffa, in partnership with Clarilis). TLT also maintains an active thought-leadership engine producing publications such as Retail Risk Outlook, ESG in Action, Disputes Outlook, Financial Horizons, Energise2030, and the Future Energy M&A Market Monitor.

TLT's go-to-market is a traditional sales-led, partner-led model serving large corporate, financial-services, energy, infrastructure, retail, and public-sector clients. Notable client relationships include a 25-year partnership with the UK Government Legal Department (GLD), and recent enterprise mandates include Dalmore Capital (£44.1m hydropower portfolio acquisition), AGR Renewables (310 MW solar / 250 MW battery financing with Bayerische Landesbank), Chint Solar (50 MW Burcot solar acquisition), Biffa (Eco-Power Green Energy acquisition plus contract automation), Low Carbon (500MW Gate Burton disposal), BOOM Power (530MW East Yorkshire solar disposal to Ampyr Solar Europe), Eku Energy (1GW+ battery storage acquisition), L&Q (Build London Partnership), and a global glassfibre-reinforced concrete equipment manufacturer transitioning to employee ownership. Headcount is stated as 1,001–5,000 employees, and the firm was ranked second globally for M&A deal volume in Clean Energy Pipeline's 2025/2026 Clean Energy Legal League Table (82 clean energy transactions advised in 2025) and fourth-consecutive-year inclusion in The Times Top 50 for Gender Equality.
