London’s financial technology sector attracted a record £8.4 billion in venture capital and growth equity investment during 2025, cementing the UK capital’s position as Europe’s leading fintech hub and the third largest globally after New York and San Francisco, according to the annual State of UK Fintech report published by industry body Innovate Finance on Monday. The figure represents a 23% increase from 2024, reversing the decline seen in 2023 when rising interest rates and a broader tech funding downturn had squeezed valuations and reduced deal activity.
The resurgence was driven by a combination of factors: improving macroeconomic conditions, a new wave of artificial intelligence-enabled financial services products attracting investor attention, and a series of high-profile fundraisings by late-stage companies preparing for potential public listings. The largest single deal of the year was a £1.2 billion Series E round raised by payments infrastructure company Volt, which is positioning itself for a possible IPO on the London Stock Exchange in the second half of 2026.
Innovate Finance chief executive Janine Hirt said the results demonstrated that London retained “an unparalleled ecosystem for building globally significant financial services companies.” She pointed to the concentration of talent from both the financial services and technology sectors, the proximity to major institutional investors and corporate clients, and the supportive regulatory environment created by the Financial Conduct Authority’s innovation-friendly approach as key competitive advantages.
Artificial intelligence applications dominated the deal flow in 2025, with AI-powered compliance and risk management tools, AI-driven wealth management platforms and AI-enabled credit assessment systems accounting for approximately 35% of total fintech investment by value. Several London-based AI fintech companies, including Quantexa, Thought Machine and Yapily, raised significant growth rounds during the year, and investor appetite for the sector shows no signs of waning in 2026.
Open banking and embedded finance — technologies that allow non-financial companies to offer banking and payments services within their own products — continued to attract strong investment. The UK’s open banking framework, which has over 10 million active users and processes over 1 billion API calls per month, is widely regarded as the most mature in the world and provides a competitive advantage for UK-based companies building products on top of it.
The regulatory environment in London remains a key attraction for international fintech companies. The FCA’s regulatory sandbox, which allows companies to test innovative products in a controlled environment, celebrated its tenth anniversary in 2026 and has now supported over 1,000 companies. The government’s recently announced Fintech Growth Fund, a £500 million initiative to support scale-up companies, is expected to provide additional momentum to the sector in 2026 and beyond.
