The Construction Act 1996: Stage Payments, Pay Less Notices, and Adjudication Rights

The Housing Grants, Construction and Regeneration Act 1996 — often called the Construction Act or HGCRA — is the cornerstone of payment rights in the UK construction industry. Despite being nearly thirty years old, it remains the primary legislation protecting subcontractors and main contractors alike from the withholding of money and the delays in payment that have historically plagued the sector. The Local Democracy, Economic Development and Construction Act 2009 introduced important amendments, but the core framework remains the 1996 Act.

The Right to Stage Payments

Section 109 of the Construction Act provides that a party to a construction contract has the right to payment by instalments, stage payments, or other periodic payments for any work under the contract that is intended to last more than forty-five days. Where the parties have not agreed on an adequate mechanism for stage payments, the Scheme for Construction Contracts applies as a default — a statutory instrument that imposes standard payment terms. For trade contractors this means that on any job lasting more than six weeks, you are entitled to demand stage payments even if the client has not proposed them and even if your original quote did not explicitly address payment milestones. The right cannot be excluded by contract. A contractor who is owed money for work already completed has a statutory right to be paid for that completed work even if the overall contract is still ongoing, and a client cannot simply hold all payment until practical completion unless the contract expressly and lawfully provides for that and the statutory minimums are met.

Payment Notices

The Act requires that the payer issue a payment notice within five days of the payment due date, stating the sum that it considers to be due and the basis on which that sum is calculated. If the payer does not issue a payment notice, the payee may issue a default payment notice setting out the sum it considers due. The payer is then obliged to pay that sum unless they issue a pay less notice in time. This process gives the payee certainty about what they will receive before payment falls due, replacing the old practice of simply waiting to see what arrived in the bank account. If no payment notice is issued by anyone, the sum named in the contractor's application or invoice becomes the notified sum and is payable in full unless a valid pay less notice is served.

Pay Less Notices and Withholding

A pay less notice is the mechanism by which a payer can legitimately withhold all or part of a payment that would otherwise be due. The payer must serve the pay less notice before the prescribed period ends — generally not less than five days before the payment due date, though the contract may specify a longer period. The pay less notice must state the sum the payer considers to be due and the grounds for any deduction or withholding. Common grounds include set-off for defective work, damages for delay, or counterclaims. If no pay less notice is served in time, the payer must pay the full notified sum, even if they believe they have a genuine claim against the contractor. Their remedy for that claim is a separate dispute process, not unilateral withholding. This anti-withholding mechanism was one of the most significant reforms introduced by the 1996 Act, since withholding was previously endemic in the construction industry.

Adjudication: The Right to a Quick Decision

The Construction Act introduced a statutory right to adjudication that applies to virtually all construction contracts in England, Wales, and Scotland. Either party to a construction contract can refer any dispute arising under it to an adjudicator at any time, and the adjudicator must reach a decision within twenty-eight days of the referral notice (or longer if both parties agree). The adjudicator's decision is binding and must be honoured immediately, even if the losing party intends to challenge it in arbitration or litigation. Courts have consistently enforced adjudicators' decisions swiftly, recognising that the purpose of adjudication is to preserve cash flow during the project rather than to produce the final resolution of all disputes. An adjudicator's decision can be reopened in arbitration or court, but in the meantime it must be paid. For subcontractors facing a main contractor who is withholding payment without a valid pay less notice, adjudication provides a fast and relatively cheap route to enforcement.

Contracts the Act Does Not Cover

The Construction Act applies to construction contracts as defined in section 104, which is broadly but not exhaustively defined. It does not apply to contracts with residential occupiers — that is, where one of the parties is a householder contracting directly for work on their own home. This carve-out is significant for sole traders working primarily in the domestic market: the statutory payment notice, pay less notice, and adjudication rights do not apply in those circumstances, and the parties must rely on the general law of contract, the Consumer Rights Act 2015 (where applicable), and the Late Payment of Commercial Debts Act for commercial B2B work. It also does not apply to contracts for certain professional services or to supply-only contracts where no installation is involved. The Act applies to oral contracts as well as written ones, though the evidential difficulties of relying on an oral contract in a dispute are obvious.

Practical Importance for Trade Contractors

For electricians, plumbers, roofers, and other trade contractors who regularly work as subcontractors on larger sites, understanding the Construction Act is directly relevant to getting paid. Knowing that you have a right to stage payments on long jobs, that the main contractor cannot withhold money without a valid pay less notice, and that adjudication is available as a fast dispute resolution mechanism gives you leverage in payment negotiations that you would not otherwise have. Many contractors do not know these rights exist, and main contractors sometimes exploit that ignorance. Keeping proper records of work completed at each payment application stage, sending payment applications in writing with the date clearly stated, and following up immediately when a payment notice is not received are all practical steps that position you to enforce your rights under the Act if necessary.

How QuotCraft Supports Construction Act Compliance

QuotCraft's milestone payment tools are designed to reflect the Construction Act's framework. When setting up a project, you can define payment stages linked to completion milestones, and the platform sends payment applications automatically on the dates you specify, with the net sum due and a description of the work completed. The timestamped record of every payment application and the communication log showing when it was sent provides contemporaneous evidence of compliance with the Act's payment notice requirements. If you need to issue a default payment notice or follow up on an unanswered application, QuotCraft's document library holds the relevant records. For contractors who work across both domestic and commercial sites, QuotCraft makes it straightforward to apply different payment structures to different contract types, ensuring that the correct terms are applied in every case.
