UK Ministry of Justice to Give 2,500 Civil Servants ChatGPT Enterprise

The UK Ministry of Justice will roll out ChatGPT Enterprise to 2,500 civil servants under a new agreement with OpenAI, announced at the OpenAI Frontiers event in London. The deal, unveiled with Deputy Prime Minister and Lord Chancellor David Lammy in attendance, also introduces UK data residency for OpenAI customers starting Friday, October 24.

The announcement extends an MOU OpenAI signed with the UK Government earlier this year to support the UK AI Action Plan, and it signals how quickly sovereign AI arrangements—where models and data stay within national borders—are becoming a competitive frontier for US AI companies courting European governments.

What does the Ministry of Justice agreement cover?

The agreement provides 2,500 Ministry of Justice employees with access to ChatGPT Enterprise. OpenAI says the deployment aims to help civil servants save time, work more efficiently, and deliver better public services. The deal supports the department's published AI Action Plan for Justice.

It follows a pilot that OpenAI says demonstrated time-saving benefits across routine tasks, including:

• writing support
• compliance and legal work
• data and research processes
• document analysis

OpenAI technology already powers tools elsewhere in the UK Government. One is 'Humphrey', Whitehall's AI assistant built to ease the administrative burden on civil servants. Another is 'Consult', which supports policymaking by automatically sorting public consultation responses—a task that typically takes officials weeks but can now be completed in minutes, while leaving important decisions to experts.

What did the Deputy Prime Minister and Sam Altman say?

Deputy Prime Minister and Lord Chancellor David Lammy framed the partnership as a matter of national positioning. "Our partnership with OpenAI places Britain firmly in the driving seat of the global tech revolution—leading the world in innovation and using technology to deliver fairness and opportunity for every corner of the United Kingdom," Lammy said.

OpenAI CEO Sam Altman pointed to usage growth inside the UK. "The number of people using our products in the UK has increased fourfold in the past year. It's exciting to see them using AI to save time, increase productivity, and get more done. Civil servants are using ChatGPT to improve public services and established firms are reimagining operations. We're proud to continue supporting the UK and the Government's AI plan," Altman said.

What is UK data residency and when does it start?

UK data residency goes live on Friday, October 24. The option gives British customers and developers the ability to store their data in the UK, helping them meet local data protection preferences or requirements. The offering applies to customers using OpenAI's API Platform, ChatGPT Enterprise, and ChatGPT Edu.

The Ministry of Justice will be the first organization to benefit from the data residency offer as part of the new agreement.

The move is separate from but complementary to Stargate UK, the AI infrastructure partnership OpenAI previously announced with NVIDIA and Nscale. Stargate UK is designed to deliver OpenAI's models on local computing power, particularly for specialist use cases where jurisdiction matters. Together, the two initiatives form the infrastructure and compliance backbone of OpenAI's sovereign AI offering in Britain.

Why does the UK matter to OpenAI?

The UK is a top-five market globally for OpenAI paid subscribers and API developers. Every day, according to OpenAI, people, developers, institutions, start-ups and leading British businesses use its tools—from NatWest and Virgin Atlantic to the home-grown unicorn Synthesia and Oxford University.

Altman's fourfold usage growth figure underscores why OpenAI is investing in UK-specific infrastructure and government relationships. For UK policymakers, the arrangements address two pressures at once: accelerating AI adoption across the public and private sectors to drive growth, and meeting data protection expectations that have made data locality a sticking point for public sector deployments in Europe.

What happens next?

OpenAI says that with UK data residency, the new public sector partnerships, and ongoing work under the MOU, it is helping lay the foundation for trusted and secure AI adoption in the UK. The company says it will keep working with the Government to help more British people, businesses and institutions benefit from AI, with the Ministry of Justice deployment serving as what Lammy described at the Frontiers event as a new standard for public sector AI adoption.
