Conclusion (the committee's words)
Using private financing requires skills and capabilities from public and private sector partners including, financial, commercial, construction, project and contract management abilities.44 The lack of a stable and consistent pipeline has contributed to the private sector not investing as much as it might have, while long contracts make it difficult to retain staff with particular knowledge and expertise for the full duration. Skills also diminish where departments have few projects.45 NISTA reported that part of the desire to improve the availability of expertise and capability within public authorities was to help reduce the number of costly legal disputes. NISTA told us it has been running several programmes to train contract managers within the public sector, that it has issued guidance and toolkits, and published an asset condition playbook to help contract managers manage their underlying contracts. NISTA also told us that its most “influential” programme is the associate pool of 60 experts from multiple fields who provide advice and support to public authorities.46

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.
