Applications to the UK Civil Service AI & Data Challenge jumped 160% year over year, with 252 ideas submitted versus 97 last time. DSIT, the Cabinet Office, and NTT DATA UK&I run the program, which invites staff to propose AI and data uses to improve services, then builds cross‑department teams to pitch to departmental CIOs. The winner receives £50,000 of development support. DWP led submissions, with HMRC and Defra tied for second. A record 339 civil servants volunteered to join project teams. Judges will pick eight ideas to advance in the new year. Past winners include AI4Peat, which mapped UK peatland drainage at national scale, and Project Constellation, which created a real‑time view of prison accommodation to save officers’ time.
