The Notice Window: A Payment Discipline for UK Commercial Teams
Payment is a timetable before it is a negotiation
In UK construction, the payment provisions of the Housing Grants, Construction and Regeneration Act 1996, as amended by the Local Democracy, Economic Development and Construction Act 2009, do not reward the most persuasive argument. They reward the party that observes the timetable. The regime creates a chain of dates, and each date carries a consequence. Where a payer fails to issue the right notice at the right time, the amount stated in a compliant application can become the notified sum. From that point, the dispute is no longer about valuation. It is about payment.
For commercial teams, the practical lesson is uncomfortable but simple: a payment notice deserves a calendar entry, a named owner and an escalation route. It does not deserve to be remembered on the day, or reconstructed after the event.
The three dates that carry the risk
Every payment cycle under the Act turns on three moments. The due date is the point at which payment becomes due under the contract. The final date for payment is the last day on which payment must be made. Between them sit the notice deadlines.
The payer's payment notice must be given no later than five days after the due date. A pay-less notice, which sets out the sum the payer considers due and the basis on which it is calculated, must be given no later than the prescribed period before the final date for payment. That period is often seven days, but it is a contract-specific figure and should be checked, not assumed.
If no payment notice is issued, the sum in a compliant application becomes the notified sum. If a payment notice is issued but no pay-less notice follows, the sum in the payment notice becomes the notified sum. In either case, the commercial argument may still exist, but the payment obligation has already been fixed.
The two-week warning
A useful discipline is to treat the final date for payment as the centre of a two-week warning window. Fourteen days before that date, the contract manager should confirm whether the team intends to pay less than the notified sum. Ten days before, a draft pay-less notice should exist. Seven days before, or earlier if the contract requires, the notice should be signed and issued.
This is not bureaucracy for its own sake. It is the difference between a considered response and a scramble. The two-week warning gives delivery teams time to supply measurement evidence, finance time to check the arithmetic and commercial advisers time to review the wording. It also gives the payer a final opportunity to decide whether a dispute is worth having.
A calendar discipline in five steps
First, map the contract. Record the due date, the final date for payment, the payment notice deadline and the pay-less notice deadline in a single payment calendar. Do this once, at contract award, and check it against any amendment.
Second, name an owner. The calendar should belong to a named individual in finance or commercial management. A shared inbox is not an owner.
Third, set three alerts: ten working days before the due date, three working days after the due date, and fourteen days before the final date for payment. The first prompts the application review. The second confirms that the payment notice has been issued. The third triggers the pay-less notice decision.
Fourth, record issue. Keep a timestamped copy of every notice and the method of delivery permitted by the contract. A notice that cannot be proved to have been given is a notice that may as well not exist.
Fifth, review monthly. At each payment cycle close, ask whether every deadline was met and whether any notice was issued late. The answer belongs in the project commercial report, not in someone's memory.
The document checklist
A payment notice file should contain the contract payment terms, the compliant application for payment, the valuation breakdown, the signed payment notice, any pay-less notice with its calculation, the evidence supporting any reduction, and a record of issue. For pay-less notices, the basis of the sum must be clear. A figure without a calculation invites challenge.
Escalation triggers
Escalate immediately if no compliant application has been received by the due date, if the valuation is disputed by more than an agreed tolerance, if the payment notice has not been issued by the third working day after the due date, or if no draft pay-less notice exists ten days before the final date for payment. Escalate also if a verbal instruction or an email has changed the scope without a written variation. Informal approvals are not notices, and they do not stop the clock.
Roles and responsibilities
Finance should own the calendar and the issue log. Delivery should own the evidence: measurements, progress records, delivery notes and variation instructions. Contract management should own the notice content and sign-off. Where one person holds all three roles, the risk of a missed date increases, not decreases.
Conclusion
The payment regime is not designed to catch people out, but it does punish those who rely on memory. A payment notice is a commercial instrument with legal effect. It should be treated with the same discipline as a programme milestone or a cost report.
At SEH Ltd, we help commercial teams build payment calendars that survive contact with a busy project. If your current process depends on someone remembering, it is not a process. It is a hope.
