Navigating payment disputes in the construction industry requires a sound understanding of statutory rights and obligations. One crucial aspect of this legal framework is the ‘Pay Less Notice’, which plays a vital role in ensuring clarity, fairness and compliance under the Housing Grants, Construction and Regeneration Act 1996 (commonly referred to as the Construction Act).
At Blackstone Solicitors, we regularly advise developers, contractors, subcontractors and other stakeholders across England and Wales on the appropriate use of Pay Less Notices. This article offers a comprehensive overview of what these notices are, when they should be issued, and the risks of non-compliance.

Understanding the Construction Act Framework
The Construction Act was introduced to improve cash flow in the construction sector and standardise payment procedures. It provides legal mechanisms that:
- Establish predictable payment schedules
- Enable prompt resolution of payment disputes
- Require transparency around sums owed
Subsequent amendments—especially under the Local Democracy, Economic Development and Construction Act 2009—have strengthened these provisions, particularly around payment notices and adjudication rights.
Central to the payment regime are three types of notices:
- Payment Notice
- Pay Less Notice
- Default Payment Notice
Each serves a distinct purpose depending on whether the paying party agrees with the amount claimed.
What Is a Pay Less Notice?
A Pay Less Notice is a formal document issued by the paying party—typically the client or main contractor—stating that they intend to pay less than the sum originally claimed by the payee (e.g. subcontractor or supplier).
It must include:
- The amount the paying party considers due
- A clear breakdown and basis for this calculation
- Delivery within a specified timeframe
The Pay Less Notice protects payers from being obliged to pay disputed or excessive amounts simply because they did not respond to a payment application.
When Should a Pay Less Notice Be Issued?
Timing is critical.
The notice must be served no later than a prescribed number of days before the final payment date set out in the contract.
This period is usually:
7 days before the final payment date, unless the contract specifies otherwise
Failure to serve the notice on time means the payer becomes legally bound to pay the full amount stated in the Payment Notice or application—even if it’s inaccurate or inflated.
Legal Importance of a Pay Less Notice
Issuing a timely and compliant Pay Less Notice has serious legal consequences. It determines:
- Whether payment obligations can be reduced
- If the payee can initiate adjudication proceedings for full payment
- The legitimacy of any deductions, such as damages, defects or variations
Courts and adjudicators consistently enforce the Construction Act’s notice regime. Payers who attempt to deduct amounts without serving a valid Pay Less Notice risk losing their case—even if the deductions are justified in substance.
In essence, process matters as much as content.
Typical Reasons for Issuing a Pay Less Notice
A paying party may issue a Pay Less Notice for several legitimate reasons:
- Defective work requiring rectification or remedial action
- Delays or disruption in performance breaching contract terms
- Overstated payment applications that misrepresent actual progress
- Unapproved variations or additional works
- Liquidated damages for contractual breaches
- Contra charges for costs incurred due to subcontractor faults
Each reason must be substantiated with evidence and included in the notice with sufficient detail.
Contents and Format of a Pay Less Notice
While there is no fixed statutory template, a compliant Pay Less Notice should contain:
- Reference to the contract and payment application
- Detailed explanation of why the payment is being reduced
- Identification of specific issues (e.g. defects, delays)
- Revised valuation of work completed to date
- Net amount the payer intends to pay
Notices should be delivered in writing, with clear dates and sender information. Email is commonly accepted, but contracts may stipulate additional requirements.
At Blackstone Solicitors, we often assist clients in drafting or reviewing Pay Less Notices to ensure legal validity and procedural correctness.
Consequences of Failing to Serve a Pay Less Notice
The implications of failing to issue a Pay Less Notice include:
- Obligation to pay the full claimed amount, regardless of disputes
- Increased likelihood of adjudication proceedings
- Exposure to legal costs and damages
- Strained commercial relationships and reputational harm
Courts have upheld payment demands where the payer failed to serve a timely and valid notice—even if the original application overstated the true value.
In one notable case, the Technology and Construction Court confirmed that procedural failures could override substantive defences, reinforcing the importance of compliance.
Adjudication and Disputes
If a Pay Less Notice is disputed or absent, the payee may refer the matter to adjudication—a swift dispute resolution process under the Construction Act.
Adjudicators can enforce payment of the full sum claimed if proper notice procedures were not followed. Payers may subsequently try to recover overpayments through separate proceedings, but this is often costly and time-consuming.
Thus, proactive issue of a Pay Less Notice is a key defence strategy.
Contractual Considerations
Every construction contract should include clear terms about:
- Payment intervals and deadlines
- Notice periods for payment and pay less notices
- Consequences of non-compliance
Commonly used contracts—such as JCT or NEC—contain standard provisions aligned with statutory requirements. Nevertheless, bespoke contracts or amendments must be carefully reviewed to ensure alignment with the Construction Act.
Solicitors play a vital role in interpreting and applying these terms correctly.
