THE PFI RECKONING · ARTICLE 11 OF 12
Insurance, Latent Defects, and Residual Liability After Handback
When a PFI contract expires, the building transfers to the authority. So does the liability for anything that goes wrong afterwards. Latent defects that were not visible during the condition survey. Insurance gaps between the SPV’s cover and the authority’s post handback arrangements. Parent Company Guarantees that expired or cannot be enforced because the guarantor no longer exists. This article examines the residual liability risks that survive handback, what the Limitation Act means for construction defects, and what authorities need to have in place before they accept the keys.
The liabilities that survive handback
Handback is not a clean break. When the SPV hands over the building and the contract ends, several categories of liability continue. Some sit with the authority permanently. Some sit with the SPV or its parent for a defined period. Some fall into a gap where neither party has clear responsibility.
The most significant residual liabilities are latent defects in the original construction or subsequent lifecycle works, insurance gaps during the transition period, and the enforceability of Parent Company Guarantees and collateral warranties from parties that may no longer exist.
Authorities that do not map these liabilities before handback will discover them afterwards, when the cost of addressing them is higher and the options for recovery are narrower.

Handback is not a clean break. Latent defects, insurance gaps, and expired guarantees are liabilities that survive the contract. An authority that does not map them before handback will discover them afterwards. |
Latent defects and the limitation clock
A latent defect is a defect in design, construction, or workmanship that was not apparent at the time of completion or during routine inspection but which becomes apparent later, sometimes years or decades later. In the PFI context, latent defects may arise from the original construction, from lifecycle replacement works carried out during the contract term, or from modifications and variations over 25 years.
Under the Limitation Act 1980, claims for breach of contract must be brought within 6 years of the breach (or 12 years if the contract was executed as a deed, which most PFI project agreements are). Claims in tort for negligence must be brought within 6 years of the date the damage occurred, or 3 years from the date it was discovered (subject to a longstop of 15 years under the Latent Damage Act 1986).
For a PFI contract signed in 2001 with practical completion of the building in 2003, the 12 year limitation period for contractual claims against the construction subcontractor expired in 2015. If a latent defect is discovered at handback in 2028, the authority may have no contractual remedy against the builder. The claim may be time barred.
12 yrs limitation period for contractual claims under deed. For a building completed in 2003, the clock expired in 2015. Defects discovered at handback in 2028 may be time-barred. |
The practical consequence is that on many PFI contracts the construction limitation period has already expired before handback occurs. The authority inherits a building where the original construction defects, if any, are no longer recoverable from the contractor through the project agreement.
Claims in tort: a longer but harder route
Claims in tort for negligent design or construction have a different limitation profile. The 3 year discovery period under the Latent Damage Act means a claim can potentially be brought later, provided the defect was not discoverable earlier with reasonable diligence. But the 15 year longstop from the date of the negligent act still applies. For practical completion in 2003, the longstop expired in 2018. The tortious route is likely closed for the original construction on most PFI contracts approaching expiry in 2026 to 2030.
Three cases together set the framework for how latent defects, limitation, and handback disputes play out in PFI. St James’s Oncology SPC Ltd v Lendlease Construction (Europe) Ltd [2022] EWHC 2504 (TCC), Mrs Justice Joanna Smith DBE, is the most cited. The PFI Project Agreement (October 2004, Leeds Teaching Hospitals NHS Trust, base contract over £173m, practical completion December 2007) required compliance with HTM 81 (then the applicable fire-precautions standard for new hospitals, since superseded by HTM 05-02). Fire safety design defects emerged 2014-17. Proceedings were issued on 11 December 2019 shortly before the twelve-year limitation period expired. The TCC found Plant Room 2 did not satisfy HTM 81; Lendlease’s revised fire strategy was held not to amount to a justified fire-engineering derogation; the Fire Strategy Defence was rejected; total quantum awarded was over £5m. The case demonstrates the importance of identifying latent defects early enough to bring claims within the limitation window, the provenance of fire-strategy documentation, and the courts’ willingness to reject a contractor’s reliance on derogated revisions to an agreed strategy. Sector context for the case is examined in Article 7 of this series.
Children’s Ark Partnerships Ltd v Kajima Construction (Europe) (UK) Ltd [2022] EWHC 1595 (TCC), affirmed on appeal as Kajima v Children’s Ark Partnership [2023] EWCA Civ 292 (Coulson LJ, 17 March 2023), concerned the PFI for the redevelopment of the Royal Alexandra Hospital for Sick Children in Brighton (Brighton and Sussex University Hospital NHS Trust, Project Agreement 10 June 2004). Cladding and fire-stopping defects emerged in 2018 in the wake of the Grenfell tragedy. The Trust applied service-failure deductions to the Project Company, which in turn sought reimbursement from Kajima under the Construction Contract. Proceedings were issued on 21 December 2021 to protect against limitation expiry. Kajima applied to strike out on the basis that the contractual Dispute Resolution Procedure (referral to a Liaison Committee, on which Kajima had no representation) had not been complied with. Both the TCC and Court of Appeal held the DRP was insufficiently clear and certain to be enforceable as a condition precedent. The case extends the St James lessons in two ways: dispute-resolution clauses must be drafted with operational clarity if they are to operate as precedents to litigation, and standstill agreements with protective claim issuance are now an established practical technique in fire-safety PFI claims approaching limitation. Lancashire Schools SPC v Lendlease [2024] EWHC 37 (TCC) reinforces both points in the schools-PFI context.
Consort Healthcare (Tameside) Plc v Tameside and Glossop Integrated Care NHS Foundation Trust [2024] EWHC 1702 (Ch), Mr Justice Richards, 3 July 2024, is the live precedent for distressed-PFI mechanics. The PFI Project Agreement was executed in 2007 with a 34-year term for a hospital project of just over £100m at Tameside. Disputes between the Trust and the Project Company over alleged service failures (including fire safety defects) led to adjudication. The adjudication award handed down on 19 January 2024 was £8,835,494 payable by Consort to the Trust. The Trust subsequently asserted entitlement to a further c.£20m of deductions for the period January-October 2022. Consort proposed a restructuring plan under Part 26A of the Companies Act 2006, the first PFI restructuring plan in the UK, to compromise current and future liabilities and avoid administration. The Trust opposed the plan; the other two creditor classes (Ambac Assurance UK Limited as senior-debt guarantor and Consort Healthcare (Tameside) Intermediate Limited as subordinated-debt holder) supported it. The convening hearing approved meetings of the three creditor classes. The High Court judgment on 3 July 2024 dealt with the Trust’s application for security for costs. A settlement was subsequently reached and confirmed in Consort’s regulatory announcement of 10 December 2024, a sculpted reduction in monthly service payments for the remainder of the term, a Trust waiver of accrued service-failure deductions and points up to settlement date, agreed rectification works (lift shafts, passive fire protection, fire doors, smoke detectors, cavity barriers, render, grounds and gardens), and a Centre of Best Practice (COBP) survey commitment. The case demonstrates that distressed PFI mechanics now run through Companies Act 2006 Part 26A as well as through the contract dispute mechanisms; that adjudication awards on service-failure deductions can drive the SPV towards insolvency in the final years; and that settlement structures with sculpted UC reductions and rectification works packages are emerging as a benchmark alternative to termination. For authorities at handback, the Consort lessons are about how late-stage disputes resolve when termination would trigger compensation payments larger than either party can defensibly fund.
Lifecycle works: the second limitation window
Latent defects do not only arise from original construction. Lifecycle replacement works carried out during the contract term, such as roof replacements, boiler installations, lift modernisations, and cladding renewals, create their own limitation periods. If a roof was replaced in 2018 under the lifecycle programme and the replacement was defective, the 12 year limitation period for a claim against the subcontractor under deed runs until 2030. If a boiler was replaced in 2022, the limitation period runs until 2034.
This creates a more favourable position for the authority on recent lifecycle works. But only if the authority knows what was replaced, when, by whom, and under what contractual terms. Without a complete lifecycle replacement record, the authority cannot identify which works may still be within limitation and which subcontractors may still be liable.
The completeness of lifecycle replacement records is examined in Article 6 of this series. The lifecycle fund reconciliation that establishes what was actually replaced is examined in Article 2.
Lifecycle replacement works carried out during the contract term create their own limitation periods. A roof replaced in 2018 under deed is still within the 12 year window until 2030. But only if the authority has the records to prove what was done, when, and by whom. |
Parent Company Guarantees: the paper protection
Many PFI project agreements include a Parent Company Guarantee (PCG) from the equity investor’s parent or from the FM provider’s parent company. The PCG is supposed to provide the authority with recourse if the SPV or the FM subcontractor cannot meet its obligations, including at handback.
Why PCGs frequently fail in practice
On early PFI deals, PCGs were often weakly drafted. Some are time limited and may have expired before handback. Some were given by parent companies that have since been restructured, merged, or become insolvent. Carillion, Interserve, and ISG are the most prominent examples. Where the guarantor has collapsed, the PCG is unenforceable regardless of its terms.
Even where the guarantor still exists and the PCG is still in force, enforcement can be difficult. PCGs typically require formal notice and a defined process for making a claim. If the authority does not follow the process precisely, the guarantee may not be triggered. The guarantor will defend aggressively because the sums involved at handback can be substantial.
What the authority should check before handback
Identify every PCG and collateral warranty in the project agreement and its schedules. Confirm the current status of each guarantor: are they still solvent, still trading, still the same legal entity? Confirm the remaining duration of each guarantee: has it expired, and if not, when does it expire relative to the handback date? Confirm the claims notification requirements: what notice must be given, in what form, within what timeframe? A PCG that exists on paper but cannot be enforced in practice is not a protection. It is a false comfort.

Insurance gaps at handback
During the PFI contract, the SPV maintains insurance cover for the building and the FM operations. At handback, that cover ends. The authority must have its own insurance arrangements in place from day one. The transition creates several specific risks.
The gap between SPV cover ending and authority cover starting
If the handback date is contested or delayed, there may be a period where neither party’s insurance clearly covers the building. Both policies may contain exclusions for the transition period. The authority should confirm with its insurers that cover commences at handback and that there is no gap, even if the handback date shifts.
Claims notification windows
The SPV’s insurance policies will typically operate on a claims made or claims notified basis. If a latent defect is discovered after handback but relates to an event during the contract period, the claim may need to be notified under the SPV’s policy within a defined window. If the SPV has wound down and the notification window has closed, the claim may be uninsurable. The authority should establish what claims notification obligations exist, what windows apply, and ensure any known or suspected issues are notified before the SPV’s policies lapse.
What a missed notification window costs
To make the notification-window argument concrete, consider an anonymised composite drawn from a recurring pattern across PFI insurance audits. The contract was a healthcare PFI approaching expiry where the SPV’s construction-period and operational insurance policies operated on a claims-made basis with a 90-day notification window from the date of discovery. At year 23, fire-stopping and compartmentation defects emerged in routine intrusive surveys triggered by post-Grenfell wider-estate inspection programmes. The remedial cost was estimated at £3.2m. The authority’s expiry team identified the defects in March, formally notified the SPV under the contract dispute mechanism in April, and assumed the SPV would in turn notify its insurer. The SPV did not. By the time the authority discovered the missed notification (at year 24, during the formal handback survey reconciliation), the 90-day window from original discovery had closed. The SPV’s insurer declined cover on the basis of late notification. The SPV’s residual capital was insufficient to fund the remediation directly, and the parent company guarantee, which the authority had not stress-tested at year five, turned out to be time-limited and had expired six years previously. The £3.2m liability fell to the authority on day one of post-handback operation. The structural lesson is that authorities cannot rely on the SPV to manage its own insurance position in the final years. Notification windows are short, the SPV’s incentive to engage with them in the run-up to handback is weak, and once a window closes, the cover is gone. Authorities approaching expiry should require evidence of notification at the point the defect is identified, not at the point the dispute is escalated, and should hold their own running record of notifications made and acknowledged.
Latent defects insurance
NISTA’s Insurance guidance (March 2025) recommends that authorities consider Latent Defects Insurance (LDI), also known as inherent defects insurance or structural defects insurance. LDI provides cover for the cost of remedying latent defects in the building’s structure and waterproof envelope, typically for a period of 10 to 12 years from practical completion. Where the original construction is outside limitation, LDI may be the only remaining route to recover remediation costs. The availability, cost, and terms of LDI at the point of handback will depend on the age and condition of the building.
Professional indemnity and contractor insolvency
Where the authority intends to pursue claims against designers, engineers, or specialist subcontractors for latent defects, those parties must still carry professional indemnity insurance. PI policies are typically renewed annually. If the party has ceased trading or allowed its PI cover to lapse, recovery is not possible even if the limitation period has not expired. The authority should identify all potential respondents for latent defect claims and confirm that PI cover remains in force before issuing proceedings.
What the authority should have in place at year five
The Senior Responsible Owner (SRO) for PFI expiry should treat insurance and residual liability mapping as a programme level workstream, initiated at the seven year mark and completed by year five before expiry. The following should be in place:
Limitation period register
A register of every contract, subcontract, collateral warranty, and PCG in the project agreement with its limitation expiry date. This register identifies which parties are still within limitation and which claims are time barred. It should be maintained by the authority’s legal advisers and updated as handback approaches.
PCG and warranty audit
A confirmed status of every guarantee and warranty: guarantor identity, solvency, remaining duration, notification requirements. Where guarantees have expired or guarantors have collapsed, the authority should understand the exposure and factor it into the post handback capital plan.
Insurance transition plan
Confirmation that the authority’s own insurance cover commences at handback with no gap. Identification of all claims notification obligations under the SPV’s policies. Consideration of LDI where original construction is outside limitation. Confirmation that potential respondents for latent defect claims still carry PI cover.
Known issues register
A register of all known or suspected defects, compliance issues, and potential claims identified during the condition survey, lifecycle fund audit, and data stocktake. All known issues should be formally notified to the SPV and its insurers before handback to preserve the authority’s position.
Insurance and residual liability are not afterthoughts. They are the mechanism by which the authority protects itself against problems that become visible after handback when the SPV has wound down and the contract no longer governs the relationship. An authority that accepts handback without mapping these liabilities is accepting risk it has not quantified and may not be able to recover.
