BDW Trading Limited v Ardmore Construction Limited

In BDW Trading Ltd v Ardmore Construction Ltd (Technology and Construction Court, 2024–2025), a historic fire safety defect dispute over a residential development in Basingstoke resulted in an adjudicator’s award of approximately £14.5 million, which was subsequently upheld and enforced by the High Court. The case marks a major real-world example of how retrospective regulatory changes under the Building Safety Act 2022 (BSA) — particularly the extension of limitation periods for safety defect claims — have translated directly into significant financial consequences for a contractor decades after original practical completion. Background

• Project: Residential development known as Crown Heights in Basingstoke, Hampshire, constructed in 2002–2004.

Parties: BDW Trading Ltd (assignee of the original employer’s rights) and Ardmore Construction Ltd (original contractor).
Defects: Multiple fire safety defects were identified many years after practical completion, including issues with cladding and fire cavities.
Regulatory Change: The Building Safety Act 2022 retrospectively extended the limitation period for claims under the Defective Premises Act 1972 (DPA) from six to 30 years, enabling BDW to pursue a claim nearly two decades after construction.
Legal Proceedings and Award

• BDW issued an adjudication in 2024 based on both contractual breach and statutory duties under the DPA 1972, relying on the extended limitation period provided by the BSA.

The adjudicator found in BDW’s favour and awarded approximately £14.5 million in damages, holding Ardmore liable for fire safety defects.
Ardmore contested the enforcement, challenging matters including jurisdiction and crystallisation of the dispute. However, the Technology and Construction Court upheld the adjudicator’s decision, granting summary judgment to enforce the award against Ardmore.
Financial Impact

• The adjudicator’s award of £14,454,914.45 in damages — later paid by Ardmore — represents a measurable financial impact directly arising from regulatory reform enabling long-latent defect claims.
• The case illustrates how historic safety defects, long past standard limitation periods, can be litigated under modern regulatory regimes and yield multi-million-pound recoveries decades after construction.

Regulatory and Industry Significance

• This decision is one of the first adjudication awards enforced based on the retrospective limitation period introduced by the Building Safety Act 2022, signalling how regulatory reform is reshaping liability exposure for contractors.

It demonstrates that historic fire safety defects can have real, enforceable financial outcomes under contemporary safety law, influencing how parties manage long-term risk and documentation.

• The case has broader implications for contractors and developers regarding record-keeping, latent defect risk, and financial planning for safety compliance liabilities.

ConclusionBDW Trading Ltd v Ardmore Construction Ltd stands as a significant real-world example of regulatory compliance (via the Building Safety Act’s extended limitation periods) driving quantifiable financial liability. The adjudicator’s £14.5 million award reflects both the cost of remediating historic construction defects and the power of modern safety legislation to revive long-dormant claims with substantial economic consequences.
