FCA's September 2025 AI Regulatory Framework Update

Executive Summary

The Financial Conduct Authority has significantly expanded its AI regulatory approach with multiple initiatives launching in September 2025, marking a pivotal moment for UK financial services AI governance.

New FCA AI Approach Webpage

[cite author="FCA Official Statement" source="FCA.org.uk, Sept 9 2025"]On 9 September 2025, the Financial Conduct Authority (FCA) published a new webpage, 'AI and the FCA: our approach', marking a significant update to their regulatory stance on AI in financial services.[/cite]

This represents the FCA's commitment to maintaining a technology-neutral, principles-based approach while supporting innovation.

AI Live Testing Extension

[cite author="FCA Press Release" source="FCA.org.uk, Sept 2025"]The application window for the first cohort of AI Live Testing was extended until 15 September 2025, with the FCA starting to work with participating firms in the first cohort in October 2025.[/cite]

The program has received overwhelming interest with implications for financial services innovation:

[cite author="FCA Innovation Team" source="FCA AI Lab Update, Sept 2025"]51 applications had been received for the AI Live Testing program, with the proposed live testing service running for 12 to 18 months.[/cite]

Critical Third Party Regime Implementation

[cite author="FCA Regulatory Update" source="FCA Policy Statement, Sept 2025"]AI providers could be directly subject to UK financial services regulation in future, with the FCA confirming that AI providers could be designated as 'critical third parties' (CTPs) depending on how use of AI in UK financial services evolves.[/cite]

The CTP regime formally came into effect in UK law on 1 January 2025 but implementation details are still being finalized:

[cite author="HM Treasury Statement" source="UK Government, 2025"]A supplier can be designated as a critical third party (CTP) by HM Treasury if it believes that 'a failure in, or disruption to, the provision of those services could threaten the stability of, or confidence in, the UK financial system'.[/cite]

Industry Impact Analysis

The regulatory changes are already reshaping the UK financial services landscape:

[cite author="IFA Magazine Analysis" source="IFA Magazine, Sept 2025"]New analysis of FCA permissions data reveals a sharp contraction in UK financial services, with the steepest declines in Mortgage & Home Finance (-11.6% individuals) and Consumer Credit (-10.5% individuals), with FCA-registered individuals dropping -4.1% and firms falling -1.7% between Q1 and Q2 2025.[/cite]

FCA's Internal AI Adoption

[cite author="FCA Strategy Document" source="FCA 2025-2030 Strategy, Sept 2025"]Making the FCA a smarter regulator is a key pillar of their strategy for 2025 to 2030. The regulator is actively using AI internally, including predictive AI to assist agents with real-time knowledge and an AI voice bot to direct consumers to the correct organisation.[/cite]

NatWest-OpenAI Collaboration: UK Banking AI Revolution

Strategic Partnership Announcement

[cite author="NatWest Group Press Release" source="NatWest Group, March 2025"]NatWest Group has become the first UK-headquartered bank to work with OpenAI as part of a collaboration that supports its strategic focus on bank-wide simplification.[/cite]

This partnership represents a fundamental shift in UK banking AI adoption strategy.

Implementation Scale and Impact

The scale of NatWest's AI implementation is unprecedented for a UK bank:

[cite author="NatWest Innovation Team" source="NatWest AI Update, 2025"]With over 275 AI projects being explored and around 25 use cases in production, NatWest has already seen substantial improvements in how it operates and serves customers.[/cite]

Measurable Customer Experience Improvements

[cite author="NatWest Customer Experience Report" source="NatWest Group, 2025"]The GenAI functionality offered by Cora+ has shown a 150% improvement in customer satisfaction, while reducing the number of times a colleague needs to intervene.[/cite]

This dramatic improvement demonstrates the tangible value of AI implementation in customer service.

Strategic Transformation Approach

NatWest's approach has evolved significantly:

[cite author="NatWest Chief Data and Analytics Officer" source="NatWest Leadership Statement, 2025"]Until recently, NatWest Group was moving gradually with AI, measuring return on investment one use case at a time. The bank has made 'a pretty big shift in the last eight months to start to reimagine pieces that really looked at customer experiences, in particular, and how we might rebuild those entirely from front to back'.[/cite]

Comparative Industry Context

NatWest's aggressive AI adoption contrasts with other UK banks' approaches:

[cite author="Banking Industry Analysis" source="Evident Insights, 2025"]Adoption has picked up momentum over the last year, according to Evident Insights, which tracks 50 of the largest banks in North America, Europe and Asia.[/cite]
