Conclusion (the committee's words)
There is no comprehensive framework for considering risk allocation between the public and private sector when working in partnership. Risks should be borne by those who are best able to manage them and should be priced appropriately. Not all risks can or should be transferred to the private sector because the cost of inappropriate transfer of certain project risks to the private sector could be disproportionately high, as ultimately, the government may have to pick up those risks, including the completion of projects if the private sector partner fails or is unable to deliver to the requirement. The lack of guidance in quantifying risk as seen for PFI contracts helped to fuel some misalignment between the additional costs of PFI, private sector return on investment (which was considered 5 disproportionately high) and the actual level of risk incurred. The Treasury says that the benefit of private finance includes the incentive for more risk management within the private sector. However, we heard that sometimes there is a misplaced belief that risk transfer to the private sector equates to risk management by the private sector, and therefore there is a false assurance that the problem lies elsewhere. This is not always the case, as ultimately the government may need to step in if a major supplier of critical infrastructure were to fail, as was the case for Carillion. recommendation The Treasury should develop a specific infrastructure financing toolkit to support public bodies in quantifying, allocating, monitoring, and managing risks for infrastructure projects. This should include the consideration of contingencies for supplier failure.

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.
