Conclusion (the committee's words)
The Treasury told us that the proportion of major projects that have been evaluated has improved since the NAO’s evaluation report. After our evidence session, the Treasury wrote to us and stated that 68% of infrastructure and construction of major projects have a high-quality evaluation plan. Across all major projects, 63% have at least some form of evaluation plan – but only 34% were deemed high quality. This leaves 37% of all major projects with no evaluation plan.24 The Treasury told us that to address some of these issues, the Evaluation Task Force published an action plan to keep improving evaluation across the major projects portfolio.25

Treasury minutes: Government response to the Committee of Public Accounts on the Thirty-ninth report from Session 2024-26
Published 15 October 2025.
Summary written by Accountability Index from the government's response. It is not the government's own words.The government states that it "agrees with the Committee's recommendation" in each of the recommendations set out in the response, describing some as implemented and others as having target implementation dates between October 2026 and May 2027.
- On the pipeline, the government says the recommendation is implemented, citing the Infrastructure Pipeline published by NISTA in July 2025, with updates "every 6 months", and NISTA has written to the Committee alongside the Treasury Minute.
- On financing models, the government agrees but says the preferred model is "the one that offers the best value for money", appraised "on a case-by-case basis" using the Green Book.
- On a central database, the government agrees with a target implementation date of May 2027. It will expand the Pipeline over time and "explore whether" the additional information sits best there or in a parallel product; the Pipeline would not include legacy PFI or commercially sensitive information.
- On risk allocation, the government agrees with a target date of May 2026, saying the Treasury and NISTA "will set out further guidance by May 2026" on contract and performance management and on resetting infrastructure projects.
