The overall value and number of infrastructure projects delivered using private finance models other than PFI are significant. For example, on the Regulated Asset Base model, around £9 billion was invested – including for Thames Tideway Tunnel and Heathrow Terminal 5. In addition, the government has recently announced that it will invest £14.2 billion in the Sizewell C nuclear power station. In June 2018, the previous Public Accounts 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. In 2021, the IPA told the Committee that it was unable to conclude its evaluation, noting that this was because it was unable to make any meaningful conclusions from the data. NISTA, which has replaced the IPA, says it is now collecting more data on performance, asset condition, and PFI contract expiry so that it can learn the lessons. Unlike PFI, other financing models are not monitored by the Treasury or NISTA and there is still no information about how the relevant data will be collected and monitored centrally. recommendation The Treasury and NISTA should publish a central database covering private finance for public infrastructure. This should include (subject to commercial sensitivity), but not be limited to: • project synopsis; 4 • lead department and counterparties; • capital value; • finance type, including any government support packages; • contract length; • project business cases, including evaluation plans; and • forecast equity returns to investors.

The NAO has … Read more The government’s ambitions for infrastructure investment are at risk of not being achieved because of sector specific skills shortages. Using private finance to support investment requires public bodies to develop and maintain specialist commercial and financial skills. The NAO has previously reported that contracting authorities often had limited in- house skills available to make critical decisions on complex projects, which can place the public sector at a disadvantage. Building specialist skills takes time and the uncertain infrastructure environment in the UK has led to a weakening of the essential skills needed for successful project delivery. The Treasury recognises these challenges and in response has created functions and centres of expertise to support public bodies. NISTA says it is running a number of training programmes and has an associate pool of 60 experts in various fields providing advice and support to public bodies. The government has also announced that the 10-year infrastructure strategy will support Skills England in its assessment of where skill gaps exist that will need to be addressed to successfully deliver key infrastructure projects. recommendation The Treasury and NISTA should set out plans for building, attracting and retaining the necessary skills to support public sector infrastructure investment. This includes skills within both the public and private sectors. Show less

Poor contract management is impacting the quality and condition of PFI assets being handed back to the public sector. Public bodies are due to pay £136 billion in unitary charges up until 2052–53 for all 665 ongoing PFI contracts, with … Read more Poor contract management is impacting the quality and condition of PFI assets being handed back to the public sector. Public bodies are due to pay £136 billion in unitary charges up until 2052–53 for all 665 ongoing PFI contracts, with half of these contracts set to expire within the next decade. However, ongoing challenges around PFI asset condition—for example in schools—need careful management to ensure only quality assets are handed back. We were pleased to hear about the hard work that NISTA’s PFI centre of excellence is undertaking to manage these issues, including the use of toolkits and experts. We understand that some issues with contract management stem from the assumption that PFI would be self-monitoring, with private sector providers reviewing their own performance and reporting back to the public body on the other side of the contract. This rarely happened in practice and should not preclude public bodies from robust contract management to ensure that private sector providers comply with their contractual obligations. The Treasury and NISTA say that the earlier PFI contracts did not have clear provisions for the condition of assets on their return to the public sector at the end of the contract. To support public bodies in managing these contracts, NISTA has published an asset condition playbook, rolled out technology and other toolkits to support contract managers. The lessons here apply equally to any other infrastructure financing model. recommendation The Treasury should set out how it will improve central support for public bodies in assessing the state of their privately financed assets and enforcing contractual mechanisms to ensure that well-maintained assets are returned to the public sector. 6 1 Government’s infrastructure strategy Introduction Show less

The Treasury added that there are “living wills” in place within contracts which list all the services that are reliant on the supplier and how those services will continue in the event of insolvency. The Treasury also told us that all departments need contingency planning and to support this, it had published four playbooks by sector, 12 guidance notes, and a sourcing playbook which includes some of the resolution plans.

Around one-quarter of respondents from public bodies to a survey stated that contracts did not contain any information on how and in what condition assets should be returned. Poorly drafted clauses open to interpretation resulted in differing views between authorities and PFI providers.62 We asked the Treasury and NISTA whether they had learned the lessons from this issue.63 The Treasury told us that at the initiation of private finance there was talk about it being self-monitoring, but this had clearly proven not to be the case.
