In July 1999 the first edition of Standardisation of PFI Contracts was published. The aim was to provide guidance on the key issues that arise in PFI/PPP projects and to outline to public sector procurers a framework to meet their requirements and deliver best value for money. Second and third editions followed. This Version 4 updates the guidance to take into account new legislation and developments in the PFI/PPP market as of 2007.
