9. There are 400 PFI contracts currently in force committing departments to future expenditure of around £100 billion.10 But we have seen no rigorous assessment of value for money on PFI contracts in force, or empirical evidence as to whether they are good value for money or not. Every pre-contract appraisal of any substance should indicate how the proposals concerned will be evaluated after completion and how the results of the evaluation will be disseminated.11 While overall responsibility for looking at individual projects rested with the relevant departmental accounting officers, OGC was obtaining feedback from a number of sources: the post-contract stage of its Gateway Review process, Partnerships UK, reports from the National Audit Office and other parties on individual projects and the OGC's networking with departmental private finance units.12
