URS Corporation Ltd and BDW Trading Ltd

The UK Supreme Court delivered a landmark judgment in URS Corporation Ltd v BDW Trading Ltd [2025] UKSC 21, significantly clarifying the law on recovery of building remediation costs for developers and the scope of contribution claims under English law. The decision addresses whether developers can recover costs incurred to fix safety defects — even where those costs were voluntarily incurred and where the developer no longer owned the properties at the time — and confirms expanded duties under key statutes including the Building Safety Act 2022 (BSA) and the Defective Premises Act 1972 (DPA). Background of the Dispute

• Parties: BDW Trading Ltd (major UK property developer, including brands such as Barratt Homes and David Wilson Homes) engaged URS Corporation Ltd to provide structural design services for two high-rise residential developments.

Context: Following the Grenfell Tower disaster and government encouragement for safety reviews, BDW discovered design defects, undertook extensive remedial works in 2020–2021, and sought to recover the cost of those works from URS as a result of alleged negligent design.
At the time of remediation, BDW no longer owned the developments, and no third-party claims had been made by owners or occupiers.
Key Legal Issues Considered by the Supreme Court

1. Voluntary Remediation and Recoverability of Costs

• URS argued that remediation costs were incurred “voluntarily” and therefore outside the scope of its duty of care and too remote.
• The Supreme Court rejected any legal rule of “voluntariness” automatically barring recovery. Whether costs are recoverable depends on causation and mitigation principles, not on voluntary expenditure alone.

Extended Limitation Periods under the Building Safety Act 2022

• The Court confirmed that the 30-year retrospective limitation period introduced by section 135 of the BSA applies to claims brought under the DPA and to related negligence and contribution claims. Thus, historic defects discovered years after construction remain actionable.

Developer’s Rights under the Defective Premises Act 1972

• The DPA duty can extend to developers themselves; URS owed BDW a statutory duty of care even though BDW no longer owned the properties at the time of remediation.

Contribution Claims under the Civil Liability (Contribution) Act 1978

• The Supreme Court held that BDW could bring a contribution claim against URS without a prior judgment, settlement, or third-party claim. Undertaking remedial works can constitute payment for “compensation” under the Act, triggering contribution rights.

Implications for the Construction Industry

• For Developers: The ruling gives significant reassurance that developers can pursue upstream claims for remediation costs against negligent designers, consultants, or contractors even if they have divested property interests and have undertaken remedial works proactively. It removes a previous barrier to recovery based solely on voluntary expenditure.

For Contractors and Consultants: The decision heightens potential liability exposure, especially where design or professional negligence contributes to defective building performance or safety issues. Parties further down the supply chain may face more claims for contribution.
For Insurers: Professional indemnity and liability insurers will need to consider the broader scope of potential claims arising from voluntary remediation and extended limitation periods.
ConclusionThe Supreme Court’s judgment in URS v BDW Trading Ltd is a major development in construction law. It clarifies that developers can seek recovery of remediation costs and contribution from liable parties even in the absence of third-party claims or immediate legal compulsion to fix defects. By affirming the expanded liability framework under the Building Safety Act and Defective Premises Act, the decision strengthens developers’ ability to address historic safety defects with legal recourse — and signals broader accountability throughout the construction supply chain.
