Introduction to the topic

This online publication provides results of a survey we conducted with public sector authorities (authorities) and which forms part of the evidence base of the NAO’s report on Managing PFI assets and services as contracts end.

This report provides information on how public authorities manage public finance initiative (PFI) contracts as they come to an end and considers whether government is making appropriate preparations to manage the expiry of PFI contracts.

We conducted this survey in 2019 and targeted English authorities with PFI contracts which have ended or will come to an end over the next seven years.

We have identified these authorities from HM Treasury’s 2018 PFI database which is produced by the Infrastructure Projects Authority. The total survey population includes 107 out of the 571 English PFI contracts, and of the 107 contracts surveyed, 89 PFI contracts were still operational at the time the survey was conducted, and 18 had expired. We received 75 out of 107 responses.

The survey population is predominantly made up of public sector infrastructure and capital equipment projects, such as roads, hospitals and schools.

The survey questions focus on the following areas:

  • The authorities’ current and intended future use of the assets and services
  • The authorities’ knowledge of the asset and their ongoing monitoring activities
  • The authorities’ resources and capability
  • Contractual provisions in relation to the hand back process


  • We split the survey questions into 8 categories (e.g. Use of Assets, Disputes, …) which are displayed in the menu bar below.
  • Select a category and the corresponding survey responses will be displayed in the area below the menu bar
  • The footnote to each survey question provides additional details on the responses as well as a the reference used in the our report on ‘Managing PFI assets and services as contracts end’ (e.g. Survey Question X.)
