BOOK YOUR FIRST FREE CONSULTUnderstanding Progress Payments in the NSW HIA Lump Sum Contract
Progress payments are an essential part of the construction process under the NSW HIA Lump Sum contract. They are payments made by the homeowner to the builder for work completed on the construction project. These payments are typically made on a regular basis, either monthly or at specific stages of the project, as set out in the contract.
Clause 17 of the NSW HIA Lump Sum contract outlines the rules and procedures for progress payments. According to this clause, the owner must pay the deposit stated in Item 2(b) of Schedule 1 on the later of the day that the contract is signed by the owner and the warranty insurance described in Schedule 6 is in force, and the owner is provided with a certificate of insurance for such insurance. The deposit is brought to account with the first progress payment.
The owner must then pay the contract price progressively as claimed by the builder. The builder must give the owner a written claim for a progress payment for the completion of each stage. The progress claim must state the amount claimed and not paid for the stage completed, the amount claimed and not paid for contract price adjustments, the amount claimed and not paid for variations, and the sum of the above amounts.
The owner must pay a progress claim within five working days of the builder giving the claim. It is important to note that payment of a progress claim is on account only, and the owner has no right of set off.
Other than in relation to the final progress claim, payment of a progress claim is on account only, and the owner has no right of set off. This means that the owner must pay the progress claim even if they dispute the amount claimed by the builder.
It is essential that homeowners understand the progress payment process and their contractual obligations under the NSW HIA Lump Sum contract. Failure to make progress payments as claimed by the builder can result in delays to the construction process, additional costs, and potential legal disputes. Homeowners should verify each progress claim accurately reflects completed work stages before making payment to avoid overpaying for incomplete construction.
It is also important to note that the maximum progress payments that can be claimed under the Security of Payment Act 1999 (NSW) applies to contracts to do residential building work when the contract price exceeds the prescribed amount. This act sets out the rules and procedures for progress payments and provides a mechanism for resolving disputes between homeowners and builders over payment claims.
Understanding how progress payments work under Clause 17 helps you identify when a builder's payment claim may be excessive, premature, or not supported by completed work. This knowledge is your first line of defence against unfair payment demands.
How Progress Claims Work Under Clause 17
A progress claim is a request for payment by the builder to the homeowner for work completed to date. Progress claims are a common feature of construction contracts, including the NSW HIA Lump Sum contract. Progress claims are used to ensure that the builder is paid for the work they have completed, and to help the homeowner manage their cash flow and budget for the project.
When the builder submits a progress claim, they will usually include supporting documentation, such as invoices or receipts, to back up their claim. Carefully review all supporting documentation to ensure claimed amounts match actual work completed and materials supplied on site. The homeowner then has a certain amount of time to pay the progress claim, as specified in the contract. Under Clause 17, homeowners must pay within five working days of receiving the progress claim.
If the homeowner disputes the progress claim, they can issue a payment schedule, which outlines the amount they are willing to pay and the reasons why the amount is different from what the builder has claimed. This payment schedule must be issued within the timeframe specified under the Building and Construction Industry Security of Payment Act 1999 (NSW).
It's important for homeowners to understand how progress claims work and to keep track of the work that has been completed on their project. This can help them to identify any discrepancies between the work completed and the progress claim submitted by the builder, and to ensure that they are only paying for work that has been completed to a satisfactory standard.
Progress claims should align with the payment schedule outlined in your contract. Each claim should correspond to a defined stage of work completion. If a builder submits a progress claim before completing the work for that stage, or claims for work not yet performed, you have grounds to dispute the claim.
How to Protect Yourself from Unfair Payment Claims
If you receive a progress claim from your builder under Clause 17 of the NSW HIA Lump Sum Contract, but believe that the builder is not entitled to payment, it is important to understand your legal rights and options to protect yourself from unfair payment claims.
First, it is important to carefully review the progress claim and ensure that it meets the requirements of the Building and Construction Industry Security of Payment Act 1999 (NSW). This includes identifying the construction work or related goods and services to which the progress payment relates, and stating the claimed amount. If the progress claim does not meet these requirements, it may be invalid and unenforceable. Verify the claim includes proper stage identification, itemised amounts for completed work, variations, and contract adjustments as required under Clause 17.
If you believe that the progress claim is invalid or that the builder is not entitled to payment, you may dispute the claim under Clause 35 of the NSW HIA Lump Sum Contract. This involves giving written notice to the builder setting out the matter in dispute and attempting to resolve the dispute or agree on methods of doing so within 10 working days. If the dispute is resolved, the parties must write down the resolution and sign it.
If you are unable to resolve the dispute, you may need to consider other options, such as engaging a solicitor to represent you in negotiations or commencing legal proceedings to recover any overpayments or damages. It is important to seek professional advice before taking any legal action to ensure that you understand your rights and obligations under the contract and the law.
Another way to protect yourself from unfair payment claims is to ensure that your contract includes a clear and comprehensive payment schedule that sets out the amount and timing of progress payments. This can help to prevent disputes and ensure that payments are made in accordance with the contract.
You may also wish to consider engaging an independent quantity surveyor or building inspector to review the progress payment and verify the work that has been completed. This can provide you with an objective assessment of the progress claim and help to identify any discrepancies or overpayments. Independent expert assessments provide objective evidence of work completion quality and quantity, strengthening your position in payment disputes or tribunal proceedings.
Documentation is critical to protecting yourself. Maintain detailed records of all site inspections, progress meetings, correspondence with the builder, and photographic evidence of work completed at each stage. If you need to dispute a claim, this evidence will support your position.
In summary, if you receive a progress claim under the NSW HIA Lump Sum Contract but believe that the builder is not entitled to payment, it is important to carefully review the claim, understand your legal rights and options, and seek professional advice if necessary. By taking proactive steps to protect yourself from unfair payment claims, you can ensure that your construction project stays on track and on budget.
Warning Signs of Unfair Progress Claims
Recognising warning signs early can help you avoid paying for work not completed or paying more than you should under your contract. Be alert to these common red flags:
Claims Before Work Completion - The builder requests payment for a stage before the work for that stage is actually complete. Progress claims must only be issued upon stage completion as defined in your payment schedule under Clause 17.
Lack of Supporting Documentation - The builder fails to provide invoices, receipts, or evidence of work completed to support the claimed amount. Legitimate progress claims should be backed by documentation.
Claims Exceeding Contract Schedule - The progress claim amount exceeds the percentage or amount specified in your contract's payment schedule for that particular stage.
Variations Not Properly Documented - The builder includes variation costs in the progress claim without proper written variation approval from you as required under the contract. All variations must be documented and approved in writing before payment is claimed.
Rushed Payment Demands - The builder pressures you to pay immediately without allowing you the five working days required under Clause 17, or threatens to stop work if immediate payment is not made.
Incomplete Stage Work - Upon inspection, you can see that work for the claimed stage remains incomplete or defective, yet the builder is claiming full payment for that stage.
If you notice any of these warning signs, do not feel pressured to pay immediately. You have rights under the contract and the Security of Payment Act 1999 (NSW) to properly assess claims before making payment.
Responding to Disputed Progress Claims: Critical Timeframes
When you receive a progress claim you believe is unfair or excessive, time is critical. Under the Security of Payment Act 1999 (NSW), you must issue a payment schedule within 10 business days of receiving the payment claim, or by the due date for payment under Clause 17 (whichever is earlier). Missing this deadline can result in losing your right to dispute the claim.
Your payment schedule must be in writing, state the amount you propose to pay (which can be zero), and provide detailed reasons why you're paying less than claimed. Common valid reasons include incomplete stage work, lack of supporting documentation, claims exceeding the contract payment schedule, or unapproved variations included in the claim amount.
If you're unsure whether a progress claim is valid, don't delay seeking legal advice. The strict timeframes under the Security of Payment Act mean homeowners often have less than a week to assess claims, gather evidence, and prepare proper payment schedules. Early specialist advice ensures you follow correct procedures and protect your legal rights without risking default.

Frequently Asked Questions About Progress Payments and Clause 17
Under Clause 17 of the NSW HIA Lump Sum Contract, you must pay progress claims within five working days of receiving them. Failure to pay on time can result in the builder suspending work, claiming interest on late payments, or potentially terminating the contract. However, if you have legitimate grounds to dispute the claim, you should issue a payment schedule outlining what you are willing to pay and why, in accordance with the Security of Payment Act 1999 (NSW). It's important to seek legal advice quickly if you're considering disputing a claim to ensure you follow the correct process and protect your rights.
Under Clause 17, payment of a progress claim is generally on account only, and homeowners have no right of set off except for the final progress claim. However, if work claimed is genuinely incomplete, defective beyond reasonable standards, or the claim includes unapproved variations, you have grounds to dispute the claimed amount through proper payment schedule procedures. This means you typically cannot withhold payment simply because you're dissatisfied with quality. However, if the work for a claimed stage is genuinely incomplete or if the builder is claiming for work not yet performed, you may have grounds to dispute the progress claim amount. Quality issues should be raised through the defects and dispute resolution processes outlined in other clauses of the contract. If you have concerns about work quality, document the issues thoroughly and seek legal advice before making or withholding payment.
Under Clause 17, a builder's progress claim must be in writing and state specific amounts: the amount claimed and not paid for the stage completed, the amount claimed and not paid for contract price adjustments, the amount claimed and not paid for variations, and the sum of these amounts. The claim should correspond to completion of a defined stage in your payment schedule. Additionally, under the Security of Payment Act 1999 (NSW), the claim should identify the construction work or related goods and services to which the payment relates. Builders should also provide supporting documentation such as invoices or receipts. If a progress claim doesn't meet these requirements, it may be invalid or unenforceable.
If you wish to dispute a progress claim under the Security of Payment Act 1999 (NSW), you must issue a payment schedule within the timeframe specified in the Act (typically 10 business days from receiving the payment claim, or by the due date for payment under the contract, whichever is earlier). The payment schedule must be in writing, state the amount you propose to pay (which may be zero), and provide reasons why the proposed amount is less than the claimed amount. The payment schedule must be served on the builder within the required timeframe, or you may lose your right to dispute the claim. Given the strict timeframes and formal requirements, it's advisable to seek legal advice immediately upon receiving a disputed progress claim to ensure proper procedure is followed.
Clause 17 of the NSW HIA Lump Sum Contract governs the contractual arrangements for progress payments between you and your builder, including when payments are due, what must be included in claims, and payment timeframes. The Building and Construction Industry Security of Payment Act 1999 (NSW) is separate legislation that provides a statutory framework for recovering progress payments, including a rapid adjudication process for payment disputes. While Clause 17 sets out your contractual payment obligations, the Security of Payment Act provides additional legal mechanisms for builders to enforce payment and for homeowners to dispute claims. The Act applies to residential building contracts when the contract price exceeds prescribed thresholds. Both the contract and the Act work together, and understanding both is important for protecting your interests.
Yes, engaging an independent quantity surveyor or building inspector to review a progress claim is a practical step to verify whether the claimed work has actually been completed to the standard required. An independent expert can assess whether the stage of work claimed is genuinely complete, whether the claimed amount aligns with the work performed, and whether there are quality issues that should be addressed. This objective assessment can provide you with evidence to support your position if you need to dispute a claim or negotiate with the builder. While there is a cost to engaging an expert, this investment can prevent you from overpaying for incomplete work or paying for work that hasn't been done. If disputes escalate to tribunal proceedings, expert reports can be valuable evidence.
If your builder threatens to stop work or suspend the project because you haven't paid a disputed progress claim, don't panic or feel pressured into paying immediately. Under Clause 17, you have five working days to pay a progress claim from when it's issued. If you have legitimate grounds to dispute the claim, you should issue a payment schedule within the required timeframe under the Security of Payment Act 1999 (NSW). Document all communications with the builder, including any threats or pressure tactics. The builder does have rights to suspend work for non-payment under certain contract provisions, but they must follow proper procedures. Seek urgent legal advice to understand your rights and obligations, ensure you're following correct dispute procedures, and protect yourself from improper pressure or potential contract breaches by the builder.
