Private Finance Initiative (PFI)

The Private Finance Initiative (PFI) was a distinctly British approach to procuring public infrastructure using private finance. Under PFI, a private sector consortium formed a special purpose vehicle (SPV) to design, build, finance, and operate a public facility over a 25 to 35 year contract period. The public authority paid an annual availability-based "unitary charge" rather than upfront capital expenditure, spreading the cost across the lifetime of the asset.

What is the Private Finance Initiative (PFI)?

PFI was introduced by the UK government in 1992 and became the dominant mechanism for public sector capital investment through the 1990s and 2000s. At its peak, PFI was used to procure hospitals, schools, prisons, courts, government offices, road improvements, and a wide range of other public infrastructure. By 2018, when the government announced it would no longer use PFI or its successor PF2 for new projects, the UK had over 700 operational PFI contracts with a combined capital value exceeding GBP 60 billion.

The core structure of a PFI contract:

• A project company (SPV) borrows from banks or bond markets to fund construction, secured against the availability payment stream
• Construction is subcontracted to a main contractor (often an equity investor in the SPV)
• Facilities management is subcontracted to a specialist FM company (often also an equity investor)
• The public authority pays a unitary charge monthly or quarterly from the point the facility is available for use
• Deductions are applied to the unitary charge if the facility is unavailable or fails performance standards defined in a service level agreement
• At the end of the contract period, the asset transfers to the public sector

PFI was criticised for the high cost of private finance relative to public borrowing, for inflexibility in the face of changing service requirements, and for the complexity of the contractual structures involved. A 2018 National Audit Office report found that the total lifetime payments on existing PFI contracts would exceed GBP 200 billion, substantially higher than the capital value of the assets procured.

Despite the end of new PFI contracts, existing PFI contracts remain active and will continue generating procurement activity (variations, lifecycle works, FM sub-contracts) well into the 2040s and 2050s.

Why it matters for bidders

PFI is no longer an active procurement vehicle for new UK contracts, but hundreds of existing contracts continue. Suppliers involved in lifecycle replacement works, FM variations, and contract modifications on live PFI contracts must understand the contractual architecture: the SPV structure, the deduction mechanism, and the hard-wired payment flows that govern how change is managed.

For non-UK European markets, PFI's structure and lessons remain relevant as a reference model for national PPP programmes.

Example

A National Health Service trust procured a new district general hospital under PFI in 2001. The SPV financed construction of the GBP 180 million hospital, which opened in 2004. The trust pays an annual unitary charge of approximately GBP 17 million (covering debt service, maintenance, and FM services) until 2039, when the hospital transfers to the NHS. Availability deductions apply if operating theatre availability falls below agreed thresholds.

Frequently Asked Questions

Can new PFI contracts be signed in the UK?

No. The UK government announced in October 2018 (Autumn Budget) that it would not sign any new PFI or PF2 contracts. Existing contracts continue unaffected. Some local authorities have sought alternative financing structures for infrastructure, but no central government successor model has been formally adopted.

What is the difference between PFI and PF2?

PF2 was introduced in 2012 as a reformed version of PFI, intended to address specific criticisms including excessive equity returns and poor transparency. PF2 included a public equity stake in SPVs, reduced the scope of services within the unitary charge, and required greater transparency on costs. In practice, very few PF2 contracts were signed before the model was discontinued alongside PFI in 2018.

Are other European countries running PFI-equivalent programmes?

Yes. France, Spain, Germany, the Netherlands, Portugal, Ireland, and Poland all operate national PPP programmes with similar structural features: private finance, long-term concessions, availability payments, and lifecycle maintenance responsibilities. These are regulated under the EU Concessions Directive 2014/23/EU where they carry concession characteristics.
