Conclusion (the committee's words)
The Treasury publishes data on the number of active PFI contracts, which includes information on: the capital value of assets; when contracts are due to expire; and the remaining unitary charges.32 As of 31 March 2024, there were 665 PFI contracts with a capital value of £50 billion – 79% of the value relating to social infrastructure and the remaining 21% to economic infrastructure.33 The NAO has previously reported that there was a lack of systems to collect comparable data for similar projects using different procurement routes, and the previous Public Accounts Committee also highlighted that there was a lack of data available to assess the actual efficiency of PFI projects.34 In June 2018, the then Committee recommended that the Treasury and IPA publish data on the benefits of PFI and set out an approach to evaluating the value for money of operational PFI projects.35 Doing so would allow for lessons learned from the evaluation to be applied to other projects, including on construction or delivery, future expiries, and contract management.36

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.
