More than 20,000 civil servants took part in a government-led trial using generative AI to support their daily work – with early results showing time savings equivalent to nearly 2 working weeks per person, per year
AI can significantly reduce time spent on government tasks – freeing up time, capacity and boosting productivity, with a landmark trial of 20,000 civil servants showing they could save nearly 2 weeks each annually by using the technology.

This is the equivalent of giving 1,130 people a full year back - every year - to focus on higher-value tasks, innovation or public service impact, rather than admin-based work - with the potential for this to rise significantly if used across the entire civil service, transforming productivity and public service delivery at scale.
The findings show the use of AI across the Civil Service will directly support the government’s Plan for Change by driving innovation, fostering economic growth, and modernising how public services operate.
The trial found that using generative AI such as Microsoft 365 Copilot to assist with everyday tasks – including drafting documents, summarising lengthy emails, updating records, and preparing reports – saved users an average of 26 minutes per day. That adds to nearly 2 weeks of time saved per year per person, delivering a significant productivity boost when scaled across the public workforce.

At Companies House, staff use Copilot to handle routine customer queries and speed up tasks like drafting responses and updating records. At the Department for Work and Pensions, work coaches are using it to personalise advice for jobseekers – helping them get faster, more tailored support.
Technology Secretary Peter Kyle highlighted the findings in a keynote discussion at SXSW London today, where he joined former Prime Minister Tony Blair to discuss reimagining government and public service delivery in the age of AI.

A DWP Work Coach involved in the trial said:
Complementing these findings, research from the Alan Turing Institute published today finds that AI could support up to 41% of tasks across the public sector, offering significant time savings. In schools, for example, teachers spend nearly 100 minutes a day on lesson planning – up to 75% of which could be supported by AI, freeing more time for the classroom. Civil servants spend around 30 minutes daily on emails, where AI could cut this effort by over 70%.

From drafting documents to updating records, the research shows AI is well-placed to handle routine admin – supporting public servants across departments.
This forms part of the government’s broader effort to modernise the state and achieve £45 billion in savings by making public services faster, simpler, and more accessible—across health, education, and beyond – while rolling out digital tools like the GOV.UK App, Chat, and Wallet, and tackling outdated legacy systems that currently cost billions in lost productivity.
