UK Regulators Launch AI Live Testing Service to Support Financial Firms’ Consumer Applications
The FCA will launch a live AI testing service for financial firms to trial AI models in real market settings by September 2025. Selected firms receive expert support to manage risks and ensure compliance.

UK Financial Services Set to Trial Live AI Testing with FCA Support
The UK Financial Conduct Authority (FCA) has unveiled plans for a new live testing service allowing financial firms to trial AI models in real market environments. This initiative, operating through the FCA’s AI Lab, aims to support firms implementing consumer-facing AI technologies while ensuring regulatory oversight.
Open for consultation until 10 June 2025, the service is expected to launch by September. It targets firms that have moved beyond initial proofs of concept and are ready to deploy AI tools in controlled live settings interacting with consumers.
Who Can Participate and What to Expect
Access to this live testing service will be selective. The FCA clarified it is not intended for firms still in early development stages or those making operational tweaks that don’t require regulatory input. Instead, it focuses on firms demonstrating effective pre-deployment testing and readiness for real-world application.
Participants will receive support from AI and regulatory experts. The FCA intends to help firms identify risks and implement safeguards to address potential harms. The service is exploratory and will not cover AI auditing, certification, or broader compliance and governance matters.
Regulatory Support and Insights
Similar to the FCA’s existing regulatory sandbox, the live testing environment may offer tailored regulatory comfort such as individual guidance or waivers where appropriate. Additionally, insights from these tests could inform future regulatory approaches and guidance for the wider industry.
The FCA plans to share non-confidential findings publicly, focusing on key questions such as:
- How to validate AI outputs meet regulatory standards
- Assessing AI model robustness
- Measuring and mitigating bias in AI models
- Managing unintended or poor AI outcomes
Expert Views on the Initiative
The initiative has been described as both pioneering and ambitious. One notable example mentioned involves AI applications in credit and loss provisioning by lenders, affecting financial resource requirements. However, the FCA is also interested in consumer-facing AI applications and how their operation can be transparently communicated to assist other market players.
Some firms may hesitate to deploy AI externally due to the FCA’s outcomes-based regulatory approach, which has been notably applied through the Consumer Duty framework. Nonetheless, the FCA’s plan to publish best practices and guidance based on live testing insights offers a pathway for building confidence in AI adoption.
Broader Context and Duration
The AI live testing service will initially run for 12 months before undergoing evaluation. This aligns with the UK government’s growth agenda and AI opportunities plan. It also reflects similar efforts by regulators in the US and Singapore to support AI integration in business.
This new service complements existing FCA initiatives, such as the regulatory sandbox, which already assist firms trialling innovative technologies.
