British governments have for many years sought to move activities from the public to the private sector. For the past decade, this has included the provision of public services not only operated but also financed by the private sector. In 2000, these private finance initiative (PFI) projects were incorporated into a wider programme of public–private partnerships (PPPs). Compared to conventionally financed procurement, the PFI approach has brought both benefits and costs. The balance of advantage is often unclear, and at the strategic level the main drivers appear still to be ideology and accounting. However in its practical application many useful lessons have been drawn and applied.
