The danger of linking a final date for payment to the submission of an invoice


The recent case of Rochford v Kilhan [2020] highlights the importance of ensuring that the final date for payment stated in your construction contract is compliant with Housing, Grants, Construction And Regeneration Act 1996 (often referred to as the Construction Act) and is not in itself conditional on the provision of an invoice.

The facts

The facts of the case are fairly familiar in the industry – a contractor (Rochford) employed a groundworks subcontractor (Kilhan); works progressed but the parties fell out over a payment application; they ended up in adjudication arguing over whether or not a valid payment notice and/or pay less notice had been served. Kilhan were successful in the adjudication on the basis that Rochford did not serve a valid payment notice or pay less notice. Rochford disagreed with the adjudicator’s decision and the parties ended up before the Technology and Construction Court in London.

As commonly occurs in the industry, the contractual payment terms linked the final date for payment to the service of an invoice stating that the payment terms were “…thirty days from invoice”. The contract also made reference to a payment schedule but critically, the schedule itself was not included in the contact.


The judge found that:

“Pegging the final date [for payment] to service of an invoice, which is itself pegged to a payment certificate, is simply impractical”

i.e. it did not comply with the Construction Act. In the end, the judge went onto state that as a result:

“…the statutory Scheme comes into play as regards the final date for payment” and that “…while a due date can be fixed by reference to…an invoice or a notice, the final date [for payment] has to be pegged to the due date, and be a set period of time, and not an event or a mechanism.”

Practical tips

Whilst this part of the judge’s decision was obiter (i.e. outside the main decision of this case of whether or not Kilhan should repay the decided amount), employers, contractors and subcontractors would do well to take heed of the following:

  1. There is a substantial risk that linking final dates for payment to the submission of an invoice will be found to be non-compliant with the Construction Act and such linkage should be avoided;
  2. The provision of a payment schedule (or in this case the absence of one) is key if it is referred to in the contact. Its absence created ambiguity and substantially contributed to the parties’ dispute. This point perfectly illustrates our experience that all disputes can be traced back to the time of contract formation;
  3. The payment due date does not mean the date by when payment must be made, that is the final date for payment. The due date is a key date from which other things are assessed such as payment notices or in this case particularly, the final date for payment;
  4. On your applications and/or invoices, we recommend that you state ‘Final date for payment’ instead of ‘Payment due’ – this will avoid confusing the terms as noted above; and
  5. It is important to understand the relationship between the Construction Act and the Scheme and when the Scheme may apply instead of your contractually agreed terms.
