Navigating PFI hand-back

A Private Finance Initiative (“PFI”) contract is a form of public-private partnership introduced in the early 1990s to use private-sector finance and expertise to deliver public services. Typically, a special purpose vehicle, referred to as Project Co, finances, designs, builds and operates a public facility under a long-term contract, with the public sector making regular payments over the contract term.

Over the next decade, hundreds of PFI and Private Finance 2 (“PF2”) projects across the UK, including hospitals, schools, roads, prisons and government accommodation, will reach the end of their concession periods. For public bodies due to receive these assets back, hand-back is one of the most important and complex stages of the project lifecycle. However, the National Audit Office (“NAO”) has warned for some time that public bodies may not fully appreciate the time, resources and complexity involved in navigating the expiry of these PFI contracts, and the transfer of rights and obligations that follow. (National Audit Office, Managing PFI assets and services as contracts end (HC 369, May 2020). Government guidance also recommends to start preparing for expiry at least seven years before. 'Preparing for PFI Contract Expiry' previously published by the Infrastructure and Projects Authority (which merged into the National Infrastructure and Service Transformation Authority ("NISTA") in 2025)

“Hand-back” is the process by which PFI assets and operations transition from the private sector back to public sector control. However, it is not simply a matter of handing over the keys. It is a structured, contractually governed process that demands careful planning, rigorous legal analysis, and proactive engagement between the public body and Project Co. Those who leave it too late risk significant financial exposure, protracted disputes, and potentially receiving an asset that is not in the condition required by the contract.

Where the risks lie

The legal challenges associated with PFI hand-back are numerous, and many legacy PFI contracts contain hand-back provisions that lack detail and practical considerations. We have highlighted several issues: 

Asset condition and lifecycle obligations - the project agreement will typically require the asset to be handed back in a defined condition, often linked to a lifecycle fund (set aside to meet the cost of maintaining/replacing elements of the asset) and maintenance regime. Disagreements over the precise requirements of the defined condition, whether those obligations have been met, and what remedial work is required to meet the standard, can be substantial.

Interaction with new climate and energy policies – the effect of legislation such as the Heat Networks (Market Framework) (Great Britain) Regulations 2025 and Net Zero policies need to be considered, as the underlying standards are likely to have changed since the PFI asset was commissioned. Public bodies should bear in mind that hand-back obligations are often tied to the output specification as it stood at financial close, rather than to current law, so the contractual hand-back condition may fall short of what is now required.

Latent defects and residual liability - defects that are not apparent at the point of hand-back can surface months or years later, and the allocation of responsibility for those defects is frequently contested. The position under the project agreement, the building contract, and any collateral warranties all need careful review to understand the options available to the public body.

Condition surveys and assessments – these are a common flashpoint. The methodology, timing, and findings of pre-hand-back surveys often become the battleground on which hand-back disputes are fought. Getting the survey process right, and understanding how to challenge or defend survey outcomes, is critical.

Employment and TUPE – such considerations should not be overlooked. Where operational staff are employed by Project Co or its subcontractors, the Transfer of Undertakings (Protection of Employment) Regulations 2006 will likely apply, requiring careful management of workforce transfers back to the public sector or to a successor operator. Issues to consider are likely to include pensions and inherited liabilities. This is crucial to achieving the goal of a smooth operational transfer.

Documentation, records management, and data transfer – these obligations can be deceptively onerous. Public bodies will require comprehensive asset information, maintenance records, and operational data to satisfy themselves that they have the right information to move forward and take proper control of the asset on expiry of the PFI contract. This should include statutory documents such as the health and safety file, the asbestos register and any fire risk assessments, as well as arrangements for the change of “responsible person” under fire safety legislation and, for higher-risk buildings, compliance with the golden thread information duties under the Building Safety Act 2022.

Property, IP, contracts and data protection – these matters should be addressed early. Public bodies should address property issues such as how any lease or licence granted to Project Co will be surrendered or terminated, how any registered interests in land will be dealt with, and who owns the plant, equipment and spare parts on site. Intellectual property rights in design documents and building management software should be assigned or licensed in order to maintain access. Key subcontracts, maintenance and utility contracts, warranties, insurances and consents should be reviewed to decide which will be novated, replaced, terminated or allowed to lapse. Any transfer of personal data, including employee and occupant information, must comply with UK General Data Protection Regulations (UK GDPR).

Procurement of replacement services – where the public body intends to put replacement FM or other service contracts in place, it will need to run a compliant procurement under the Procurement Act 2023, which takes time and should be built into the hand-back programme. Varying or extending the existing project agreement to bridge a gap, or simply to maintain the status quo, will also require compliance with the relevant procurement regulations in place when the contract was awarded. In some cases, a voluntary termination or early negotiated exit may benefit both parties and be a better alternative to waiting for expiry.

Practical Steps

Our advice to those due to receive hand-back of a PFI asset is straightforward: start early and be methodical. Government guidance suggests that public bodies should begin reviewing hand-back provisions around five years before expiry. Here are the key steps we recommend.

Review your project agreement thoroughly. Understand precisely what the hand-back provisions require, identify any ambiguities, and take legal advice on how gaps or uncertainties are likely to be resolved. Many legacy contracts were drafted when hand-back felt a lifetime away, and the drafting often reflects that. Seeking advice can provide valuable insight into how the market and indeed the courts are interpreting obligations in the contractual documents. 

Commission an independent condition assessment early. Understanding the current state of the asset (including how it interacts with new climate-related obligations), and the gap between that state and the contractual hand-back condition, gives you time to plan and budget for remedial works rather than facing them under time pressure. Existing government guidance provides helpful, practical frameworks that aim to eliminate unnecessary duplication of surveys and reduce the risk of disputes arising between the parties. Published by NISTA and also the Asset Condition Playbook released in March 2025.

Engage with Project Co proactively. A collaborative approach to hand-back planning is almost always preferable to an adversarial one. Early dialogue on survey methodology, programme, and expectations can prevent disputes from crystallising.

Audit the records and data prior to hand-back. Ensure that maintenance logs, lifecycle records, warranties, and operational documentation are complete and accessible, and that you understand how the asset functions. Gaps in the documentary record can create practical problems further down the line when the opportunity to address this issue with Project Co has already passed.

Take advice on workforce and TUPE implications. Work with Project Co and the FM provider to identify affected employees early and plan the consultation and transfer process in good time. This will help ensure a smooth operational transfer.

Map property interests, IP and third-party contracts. Identify any leases, licences or registered interests granted to Project Co and agree how they will be surrendered or terminated, and confirm ownership of plant, equipment and spare parts on site. Ensure the public body will have the necessary rights to use design documents and building management software after expiry. Schedule the key subcontracts, maintenance and utility contracts, warranties, insurances and consents, and decide which should be novated, replaced or allowed to lapse, leaving enough time for counterparties to consent. 

Have a plan for how the asset will be controlled post hand-back. Understand the new operational requirements and pressures that will now be the responsibility of the public body once the asset is transferred.

Conclusion

The most common mistakes that we see public bodies make during, and in preparation for, the hand-back process are:

• leaving it too late to start liaising with Project Co, meaning unnecessary pressure is added to the hand-back process given the impending expiry date;
• not properly understanding the condition that the asset needs to meet at hand-back stage, such that opportunities are being missed to request necessary rectification works;
• not utilising the range of rights available under the project agreement to help drive the hand-back process forward, such as: a requirement for a joint survey, a hand-back retention or deduction from the final unitary charge payment, a hand-back bond or other security, or the right to carry out rectification work and recover the cost; and
• failing to consider how the public body will run the asset operationally once it is handed back. Having not been responsible for the day-to-day running of the asset for the duration of the PFI contract, public bodies need to be properly prepared for the increase in financial commitment and operational workload that will arrive once the asset is transferred.
