Treasury: Artificial Intelligence

Asked by Sir John HayesConservativeTreasuryTabled Answered 10 June 2026UIN 5858

The question

To ask the Chancellor of the Exchequer, whether her department permits (1) Ministers, (2) Special advisers and (3) officials to use (a) Chat GPT, (b) Google Gemini, (c) Claude, (d) Deepseek and (e) Grok as part of their official duties.

Answered by Rachel Blake

Ministers, special advisers, and officials in HM Treasury have access to HMT-GPT, our internal AI tool which is built on Claude and ChatGPT, and Copilot, which have been assured to the appropriate security standards and approved for official use.

The use of publicly available or consumer versions of generative AI tools, including those named in the Question, for official business is not permitted. Approved enterprise tools are configured so that departmental data is held securely and is not used to train publicly available AI models.
