The Whitehall agency is already making almost ubiquitous use of some generic assistance and LLM tools, while plans are afoot to increase rollouts for use cases including analysis and policymaking
HM Treasury claims that, during the 2025/26 year, the department’s deployments of artificial intelligence technology progressed “from early experimentation to organisation-wide use”.
The finance department has already put in place general productivity tools – including its own in-house technology – and plans to continue growing its use cases, by deploying AI for new and more specialised purposes, including policymaking.
In its recently published annual report and accounts, the Treasury says that its senior management team supported the creation of a new “a centralised orchestration model, [while] establishing a single Digital and Data function, a Digital, Data & AI Board, and an AI Champions group to prioritise high-value use cases and scale solutions”.
And, following the conclusion of FY26, the finance department deployed Microsoft 365 Copilot to all its 2,000-plus staff “after a successful trial” of the system.
The rollout has already been “adding to productivity gains seen with HMT-GPT – our internal tool giving staff access to cutting edge large language models”, the report says.

The document adds: “Around 1,000 staff have attended ‘Introduction to AI’ training sessions to build capability, supported by a Prompt Guide, Use Case Library, Community of Practice and AI Portal to signpost tools and guidance. Beyond general productivity tools, structured deep dives are mapping AI opportunities across policy teams and targeted AI and automation work is driving efficiencies across operations including correspondence triage and drafting, delivery assurance in NISTA (the National Infrastructure and Service Transformation Authority), case management in OFSI (the Office of Financial Sanctions Implementation), and corporate processes like handling HR queries and onboarding.”
The Treasury intends to continue to accelerate the use of new technology during the ongoing 2027 fiscal year, including efforts “to target and embed the use of AI, further building capability, trialling new tools and continue be rolling out agentic AI to support coding and analysis, policy development and key processes across HM Treasury”.
The department’s training unit has also “developed a central AI and digital offer, with opportunities and resources aiming at different levels of expertise”. The aim of courses included in these offerings is “to help colleagues become more confident and skilled using AI tools to support them to be more effective and impactful in their roles”, according to the report.
Other tech developments during FY26 include the implementation of a new “digital assistant to streamline access to HR support” for Treasury employees.
The department’s Data Hub also undertook efforts dedicated to “strengthening data quality and analytical capability across HM Treasury”.
The report says: “Hawkeye, our core economic data platform, now covers over 80 live pages while a Power BI training programme has been delivered to over 100 colleagues to democratise analysis. In support of the Autumn Budget, two new digital tools were launched: the Fiscal Events Database for tracking development of policy measures and the Digital Scorecard for real-time visibility of budget package impacts.”
