TLT elects financial services head Andrew Lyon as senior partner

National law firm TLT has announced the election of Andrew Lyon, Partner and Head of Financial Services, as its next Senior Partner.

Lyon will begin his three-year term on 1 January 2026, taking over from Sasha Butterworth, who has held the role since 2022.

Lyon’s appointment comes at a time of continued expansion for the firm, with a clear mandate to support strategic growth while championing a culture rooted in values, accessibility, and opportunity. He brings with him more than 18 years of experience as a Partner at TLT and a decade of leadership as a member of the firm’s Executive Board.

Since joining TLT’s London office in 2007, Lyon has played a transformative role in shaping the firm’s Financial Services Disputes and Investigations team into one of the UK’s largest. He also served as Location Head for the London office for 12 years, helping to establish TLT’s presence in the City as a key player in financial services law.

In his current role leading TLT’s Financial Services Sector, Lyon advises some of the country’s foremost banks and financial institutions, earning a reputation for sharp strategic insight and client-first thinking. His promotion reflects both his individual leadership and the firm’s continued commitment to client excellence.

Commenting on his appointment, Lyon said: “I feel extremely proud to step into this role at such a pivotal time in the evolution of TLT. I am passionate about TLT and our potential, and it means a lot to be trusted to represent the firm in this way. For me, it’s about providing continuity at a time of significant growth and transformation, strengthening internal and external engagement through listening to and connecting our people and clients, and creating opportunities for the next generation and the businesses we advise.”

As Senior Partner, Lyon will work alongside Managing Partner John Wood and the wider leadership team to steer the firm through its next phase, with a focus on deepening client relationships and fostering an inclusive and empowering culture.

John Wood praised the appointment, saying: “Andrew’s sector expertise, strategic insight, and unwavering commitment to our clients and our people make him exceptionally well-placed to support TLT on this next phase of continued growth.

“Andrew and I have worked closely together on our Executive Board for many years, and we share an ambition, passion and confidence in the exciting future of this firm.”

Wood also paid tribute to outgoing Senior Partner Sasha Butterworth, who will continue her work as Head of the Pensions Team.

“In the last three years, Sasha has played an important role in driving our sustainability strategy, opening up the legal sector to all backgrounds and ensuring we continue to be seen as the firm of opportunity.”
