The UK's identity verification market has become one of the most fiercely contested segments of the fintech ecosystem, with Onfido and Jumio each claiming significant gains in market share during 2025. Onfido, now operating under the Entrust brand following its acquisition in late 2024, reported that it processed over 30 million identity checks for UK financial services clients in the first half of the year, a 22 per cent increase year-on-year. Jumio countered by announcing partnerships with three of the UK's top ten building societies and a renewed contract with a major high-street bank.

The competitive dynamic has been fuelled by tightening regulatory expectations. The FCA's updated guidance on digital identity verification, published in June 2025, raised the bar for document authenticity checks and liveness detection, effectively mandating the use of AI-powered verification tools for all regulated onboarding processes. "Manual document review is no longer sufficient to meet the standard the FCA expects," said Matthew Moynahan, chief executive of Onfido's parent company Entrust. Both firms have invested heavily in NFC chip reading technology, which extracts data directly from the chip embedded in modern passports and identity cards, providing a higher level of assurance.

Smaller challengers including Sumsub, Veriff, and iProov are also gaining traction, particularly among crypto exchanges and neobanks that value speed and developer-friendly integration. Industry analysts at Juniper Research estimate that the UK identity verification market will be worth £1.2 billion by 2027, more than triple its 2023 valuation. The sector's growth reflects a broader recognition that robust identity checks are not just a compliance requirement but a critical line of defence against financial crime.
