Late payments in construction
Updated 28 June 2026
Construction consistently ranks among the sectors worst affected by late payment. Long contractual chains, retentions and frequent disputes mean cash can sit unpaid for months, and the failure of a single party upstream can ripple downwards.
This guide explains why the sector is high-risk and what subcontractors and suppliers can do to protect themselves.
Why construction is high-risk
Payment passes through layers — client, main contractor, subcontractors, suppliers — so a delay or insolvency high in the chain affects everyone below it. Retentions hold back a percentage of each payment, sometimes for a year or more, and disputes over variations and quality are common.
Know your payment rights under the Construction Act
Most UK construction contracts are governed by the Housing Grants, Construction and Regeneration Act 1996 (the 'Construction Act'). It gives parties a right to stage payments, a structured payment-notice process, the right to adjudication to resolve disputes quickly, and — if a properly notified sum is not paid — a right to suspend performance.
Understanding these mechanisms, and serving the correct payment notices on time, is one of the strongest protections available in the sector.
Practical protections
Beyond your statutory rights, the same fundamentals apply with extra discipline:
- Use clear written contracts and applications for payment, and serve payment notices on time.
- Track retentions actively and chase their release on the due dates.
- Credit-check main contractors before taking on significant work.
- Avoid over-reliance on a single contractor or project.
- Claim statutory interest on overdue commercial debts where applicable.
