Recommendation (the committee's words)
Government transformation and efficiency efforts are increasingly reliant on newer technologies such as artificial intelligence (AI).47 Legacy systems and poor-quality data remain a major barrier to reaping the full benefits.48 We heard that addressing data and legacy issues requires sustained effort and resilience and remain concerned that the pace of addressing the challenge is not keeping up with what is needed in today’s world and that despite this, departments are already experimenting with AI.49

Government response
The government responded to the whole report on 1 April 2026 (deadline 12 February 2026).
Summary written by Accountability Index from the government's response. It is not the government's own words.The government agrees with the Committee's recommendations on cost ownership, costing guidance, single service owners and data leadership, and disagrees with one on prioritising legacy systems for further investigation.
- On accountability for costs, the government agrees and sets a target date of July 2026: the Treasury will issue an updated Dear Accounting Officer letter setting expectations that senior leaders identify, use and improve service-level cost information.
- On the six-month request to prioritise legacy systems for investigation, the government disagrees, stating it "does not agree that this recommendation should be an immediate priority of the next 6 months" given work already in progress.
- On the baselined list of legacy systems, the government agrees and will share "the available data" with the Committee chair by March 2026, but does not intend to make the list publicly available because of cyber-attack concerns.
- On Senior Service Owners, the government agrees with a target of March 2027: it will issue a letter encouraging Permanent Secretaries to assess gaps within 6 months and appoint SSOs within 12 months, with the timescale "accelerated if possible".
