Construction Act payment provisions

The Housing Grants, Construction and Regeneration Act 1996 was substantially amended with effect from October 2011. Soon afterwards, people started playing games with its provisions - some can be very expensive for the loser.

The typical contracts to which the Act applies are building and engineering contracts; the appointments of architects, engineers, and other construction professionals; and development agreements that do not also transfer a major interest in land.

The Act requires all such contracts to contain an 'adequate mechanism' to determine what payments become due and when. In a broad overview, the following provisions are included:

• There must be a 'due date' for each payment;

• There must be a 'final date' for each payment;

• The contract must require a 'payment notice' to be given within five days of the due date, stating what is to be paid and the basis on which it is calculated - this can be a duty of the payer or the payee;

• If the payer is to serve the payment notice and fails to do so, then the payee can serve a default payment notice, or if the payee's application for payment sets out the amount claimed and the basis on which it was calculated, then the payee's application for payment (e.g. an invoice) can automatically be deemed to be the default payment notice;

• If the payer changes their mind or disagrees with a payment notice, or a default payment notice served or deemed served by the payee, they must serve a 'pay less' notice, setting out what they propose to pay and the basis on which this is calculated, a given number of days before the final date for payment - if they fail to do so, then the sum stated in the payment notice is payable on the final date for payment;

• Payment cannot be made conditional on someone giving a notice to the payee about what payments are due (e.g. a certificate from the project manager, who will of course be working for the payer); and

• 'Pay when paid' clauses are generally banned.

If any notified sum passes its final date without
a pay less notice being served in respect of it,
in time, the payee can go to the courts for summary judgment and/or to adjudication to
get a decision within 28 days (which the court
will enforce summarily) for payment of the notified sum. The payee can also serve a seven-day notice and suspend all further work.

It's small wonder that some payers try to undermine the protections for payees, or that some payees try to exploit payer errors in order
to gain money they're not really entitled to. This article looks at some of the games being played, not all of which have yet been ruled on by the courts.

Due date and final date

The simplest game to play is to set out a list of invoice submission dates in a schedule to the contract, to say elsewhere in the contract that payments are 'due' 30 days after receipt of the invoice, and to say in yet another clause that the final date for payment is 30 days after the payment becomes due, thus giving a 60-day payment cycle which looks like a 30-day one.

This sort of thing fools a lot of non-lawyers and risks repudiatory breach of contract if the payee tries to exercise the right to suspend work on the ground of late payment based on the wrong date.

Specific invoicing requirements

It is common for contracts to say that the due date for payment (or sometimes the final date) does not occur until a valid VAT invoice has been received by the payer. Sometimes, particularly when the payer is a large organisation with its own accounts department operating formal internal payment processes, the payment clause sets out further and very specific requirements for the payee to comply with when applying for payment. A non-compliant application for payment will not be adequate to trigger the due date (or sometimes the final date). This is perfectly reasonable.

It becomes unreasonable when the contract sets up artificial hurdles that are deliberately made difficult to comply with before an application is considered valid to trigger the due date. Such wording is normally nothing to do with genuine payment processes but is intended as a safety net for a payer who has failed to serve a 'pay less' notice in time. Requirements for unreasonable and/or unclear levels of supporting information, or hard copy applications served on one specific date each month, are examples.

Disputed amounts

As mentioned above, each payment must have a due date and a final date, and a payment cannot be made dependent on the payee receiving a notice or certificate from anyone. However, this does not stop payers from drafting contracts that try to get around this. Payers want to try to ensure that they only have to pay sums they do not dispute. The following are a few examples to watch out for:

• The due date is tied to the payer's receipt of a valid invoice for the sum due. The contract also says that if any amount is disputed by the payer, the payee has to issue a credit note for the original invoice, which then ceases to be valid, and submit a revised invoice for the undisputed amount. The disputed amount may be invoiced following determination of the dispute. A disputed amount therefore never becomes due until it ceases to be disputed;

• The payee has to submit an application rather than an invoice, and only when the amount due is agreed can it be invoiced. Sums become due on receipt of a properly submitted invoice. A sum that is not 'agreed' therefore never becomes due; and

• The final date for payment is 30 days after the due date in respect of undisputed sums, but in the case of disputed sums the final date for payment is seven days after the determination or settlement of the dispute. Disputed sums therefore become due but don't have to be paid until they cease to be disputed.

Pay when paid

Such clauses are generally banned, but payers try to achieve a similar effect by saying that the final date for payment is seven days from the earlier of the date of the payer's receipt of funds from the client or the date of completion of all of the work under the contract. In other words, the final date for payment is extended to the end of the job, but can be 'accelerated' if the payer receives funds earlier - pay when paid by another name.

Inflated interim applications

This is the high-stakes game, played mainly by main contractors and developers. Winners can walk away with millions of pounds to which they are not entitled, and the losers are currently in a legal grey area regarding how, when, and possibly even whether they can recover their overpayments. It is no surprise that this game has made it to the Court of Appeal and the Technology and Construction Court on a number of occasions.

The underlying facts are simple. The contractor issues a payment application for more, sometimes far more, than they are entitled to receive (sometimes due to optimism, sometimes due to a genuine dispute, sometimes perhaps 'carelessly'). The employer fails to issue a pay less notice in time. The contractor goes to court for summary judgment, or to adjudication and then to court for enforcement of the adjudicator's award, on the ground that the notified sum has passed its final date for payment, no pay less notice has been received, and there is therefore no defence.

Standard Joint Contracts Tribunal contracts do not allow overpayments to be corrected until the final account at the end of the job, so the contractor gains a huge cash-flow advantage (i.e. the overpayment cannot be corrected in subsequent valuations but has to be assumed to have been correct until the final account).

What if the overpayment, due to the failure to serve a pay less notice in time, related to the final account itself? The courts have struggled to find a way to allow recovery, and construction lawyers are not persuaded that the ways found so far will stand the scrutiny of the higher courts.

To summarise the case law on this is beyond the scope of this article, but there are numerous articles in the construction legal press about it, and the best starting point is probably the Court of Appeal's judgment in Harding v Paice [2015] All ER (D) 11 (Dec) and the cases cited in it.

One obvious step for solicitors to take is to make sure contracts are amended so that interim payments can be re-opened and overpayments recovered before the final account.
