New Developments for AI in UK Financial Services
As 2026 unfolds, the UK’s financial services sector is witnessing significant developments regarding the impact of artificial intelligence (AI). One of the notable initiatives is the launch of the Mills Review by the Financial Conduct Authority (FCA), aimed at assessing the long-term implications of AI on retail financial services.
This article outlines the primary developments and AI-related issues expected to draw particular interest throughout the year.
Main Developments
- The FCA’s Mills Review focused on the long-term effects of AI on retail financial services.
- House of Commons Treasury Committee published a report on “Artificial Intelligence in Financial Services.”
- Appointment of two “AI Champions” by the UK government.
- Launch of a consultation by the UK Jurisdiction Taskforce.
While not specific to financial services, the UK Information Commissioner’s Office (ICO) released a report on agentic AI, addressing data protection and privacy risks associated with the technology.
The Mills Review
On 27 January 2026, the FCA initiated the Mills Review to explore how advancements in AI could transform retail financial services. The review process began with a Call for Input Engagement Paper that outlines four interrelated themes:
- Future evolution of AI technology – Investigating potential developments in AI, including more powerful and autonomous systems.
- Future impact of AI on markets and firms – Assessing how these advancements could modify competition and market structures.
- Future consumer trends – Evaluating how AI might enhance consumer outcomes and alter demand for financial services.
- Future regulatory approach – Considering how regulators may need to adapt to ensure effective market functionality.
The Engagement Paper highlights several potential impacts of AI:
- Market power could shift from financial services firms to AI firms controlling consumer interfaces and data.
- Consumers may increasingly interact with financial services through AI-mediated interfaces, altering competition dynamics.
- New risks, including sophisticated financial crimes, could emerge, posing challenges for detection and prevention.
- Improved data presentation by firms could enable quicker regulatory responses.
While the FCA does not intend to introduce AI-specific regulations, it will rely on its existing principles-based regulatory framework while adapting to AI integration in financial services.
Feedback and Future Steps
The deadline for comments on the Engagement Paper is 24 February 2026. Insights gathered will inform recommendations presented to the FCA Board in summer 2026.
Treasury Committee Report
On 20 January 2026, the Treasury Committee published a report examining the opportunities and risks posed by AI within the financial services sector. The Committee concluded that while AI presents significant benefits, authorities are not adequately managing the associated risks.
Key recommendations include:
- The FCA should produce comprehensive guidance on the application of existing consumer protection rules to AI.
- The Bank of England and the FCA must conduct AI-specific stress testing to prepare for market shocks.
- HM Treasury should designate major AI and cloud providers as critical third parties.
AI Champions Initiative
The UK government has appointed two industry figures as AI Champions to promote safe and scalable AI growth in financial services. Their responsibilities encompass identifying innovation opportunities and addressing barriers to AI adoption.
UK Jurisdiction Taskforce Consultation
The UK Jurisdiction Taskforce has launched a public consultation regarding liability for AI harms. It seeks input on various legal questions concerning AI, including definitions, responsibility, and professional liability.
Conclusion
As AI continues to evolve, it will remain a focal point for policymakers and regulators in the UK throughout 2026. The FCA’s clear articulation of AI-related issues will guide the financial services sector as it navigates the complexities of integrating this transformative technology.
