The UK’s FCA has launched live testing of artificial intelligence across financial services, signalling a significant move toward supervised innovation in retail banking.
Major firms including NatWest, Santander and Monzo are among the first participants in the regulator’s AI Live Testing initiative, reflecting its growing role in shaping responsible technology deployment in finance, claims Finextra.
First proposed in April, the initiative is designed to give selected firms hands-on regulatory and technical guidance as they trial AI in actual market environments. The FCA will work closely with Advai, its specialist technical partner, to help institutions develop, assess and implement AI systems with a focus on safety and accountability.
The first testing cohort includes Gain Credit, Homeprotect part of the Avantia Group, NatWest, Monzo, Santander, Scottish Widows part of Lloyds Banking Group, and Snorkl. Their projects focus largely on consumer-facing applications, emphasising the regulator’s interest in how automated decision-making may affect customer outcomes.
AI concepts being trialled include digital tools for debt resolution, financial advisory functions, smarter customer engagement capabilities and automation for complaints handling. Other use cases aim to help customers improve money management behaviours by supporting spending and saving decisions, pointing to emerging links between AI innovation and household financial resilience.
The FCA highlighted its intention to act as an enabler rather than a barrier, giving firms a controlled environment to test new capabilities without risking customer harm. FCA chief data, information and intelligence officer Jessica Rusu said, “Our new AI Live Testing service helps firms who are ready to use AI in live markets. By working closely with firms and our technical partner Advai, we’re helping to make sure that AI is developed and deployed safely and responsibly in UK financial markets.”
With momentum building, the regulator has confirmed that applications for the second testing group will open in January 2026, with live experimentation set to begin in April. This suggests that AI oversight and innovation support could become embedded features of the FCA’s supervisory model as financial institutions accelerate their digital transformation.
