Building a home or undertaking a major renovation in Victoria is one of the most significant financial commitments you will ever make. Yet many homeowners sign contracts and watch construction begin without fully understanding how their money flows to the builder throughout the project. This is where progress claim construction becomes a critical concept to grasp before a single brick is laid.
A progress claim is essentially a formal payment request submitted by your builder at key stages of construction. If you do not understand how this process works, you risk overpaying, losing leverage, or finding yourself in a dispute with little protection. Victorian consumer law provides important safeguards, but only those who know the rules can use them effectively.
In this tutorial, we will walk you through everything a Victorian homeowner needs to know about progress claims. You will learn what they are, how they are structured under Victorian building contracts, what your rights are when you receive one, and the warning signs that something may not be right. By the end, you will feel confident navigating this essential part of the construction payment process.
What Is a Progress Claim in Construction?
A progress claim, sometimes called a progress payment, is a formal payment request submitted by a builder once a defined stage of construction has been genuinely completed. The key word there is genuinely. This is not a billing convenience or a goodwill gesture; it is a contractual trigger with legal weight behind it. Under Victoria’s Domestic Building Contracts Act 1995, progress payments are tied to verified stage completion, meaning the work must be done before the claim is valid. Submitting a progress claim for work still underway is not just bad practice, it is a breach of the Act.
How staged payments differ from a lump-sum model
In a lump-sum arrangement, the full project cost is settled at completion, which creates enormous financial exposure for everyone involved. A staged payment model distributes that risk across the build timeline. The homeowner pays in portions as each stage is completed, and the builder receives regular income to fund ongoing labour and materials. Neither party carries all the financial weight at one point in the project. This structure is standard across new home builds, renovations, extensions, and unit developments in Victoria, and it exists precisely because construction is long, complex, and unpredictable.
Why the model protects both sides
For homeowners, staged payments mean you are only ever paying for work that has actually been delivered. You are not pre-funding stages that have not started. For builders, the model means they are not financing an entire project out of pocket while waiting for a single final payment. As Docketbook explains in their guide to progress payments, progress payments “ensure consistent income and help cover ongoing costs, including input costs for the project and staffing expenses for labour onsite.”
One misconception worth clearing up: a progress claim is not an invoice for work in progress. It is only valid once the stage it refers to is complete and, where required, has passed a building surveyor inspection. Paying a progress claim before a stage is finished can leave a homeowner unprotected under Domestic Building Insurance if a builder becomes insolvent. For a broader overview of how progress claim documentation and processes work in practice, Autodesk’s construction progress claims guide is a useful reference.
Progress claims apply across the full spectrum of residential construction work, not just ground-up new builds. Whether you are building a new home, adding an extension, completing a renovation, or undertaking a unit development, the same staged payment principles apply.
The Legal Framework Governing Progress Claims in Victoria
Understanding the legal landscape behind progress claims in Victoria is not optional reading. It directly affects your rights as a homeowner, your financial exposure at each build stage, and what a builder can lawfully ask you to pay and when.
The Domestic Building Contracts Act 1995 and What It Means for You
The Domestic Building Contracts Act 1995 (Vic), administered by Consumer Affairs Victoria, sets the rules that govern how deposits and progress payments must be structured in any residential building contract in Victoria. In practical terms, this means a builder cannot simply invoice you whenever cash flow suits them. Payment must be tied to genuine, defined construction milestones, and there are statutory limits on how much a builder can collect as a deposit before work begins. For homeowners signing contracts in 2026, this legislation is your baseline protection. It is what transforms a payment schedule from a builder’s wishlist into a legally enforceable framework where each dollar you hand over corresponds to measurable progress on site.
BACISOPA: Cutting Through Disputes Without the Courts
The Building and Construction Industry Security of Payment Act 2002 (Vic), commonly called BACISOPA, exists for one core reason: to keep money flowing through construction projects quickly and without expensive litigation. If a payment dispute arises, BACISOPA provides a rapid statutory adjudication process. The builder serves a payment claim, the homeowner or respondent issues a payment schedule, and any contested amount is referred to an independent adjudicator who typically resolves the matter within weeks rather than years. This matters enormously in practice because unresolved payment disputes are one of the most common reasons builds stall. As Muscat Tanzer’s construction claims series explains, the Act was designed to protect cash flow across the entire construction supply chain, not just at the top level between builder and client.
The 2025 Amendment Bill: What Changed for 2026 Contracts
The Domestic Building Contracts Amendment Bill 2025 passed Victorian Parliament on 11 September 2025, and its provisions apply to contracts entered from 2026 onward. The amendments update key aspects of the existing DBCA framework, including deposit and progress payment provisions, introducing stronger protections for homeowners at the contract formation stage. If you are signing a building contract this year, it is worth confirming with your builder which version of the payment schedule applies to your contract. This is one of the most timely legislative developments affecting residential construction in Victoria right now, and it remains largely unaddressed in builder-published content.
AML/CTF Compliance: A Quiet Change Worth Knowing
From July 2026, expanded Anti-Money Laundering and Counter-Terrorism Financing (AML/CTF) requirements come into effect and may impose new financial documentation obligations on parties involved in property and construction transactions. For homeowners making staged progress payments, this could mean lenders, conveyancers, or other parties in the transaction require additional identity verification or source-of-funds documentation. Neither homeowners nor builders should be caught off guard by this. Being prepared with clean financial records at each milestone stage is simply good practice.
Why the Ban on ‘Paid When Paid’ Clauses Matters to Your Build
BACISOPA explicitly voids any contractual clause that allows a builder to withhold payment to subcontractors on the basis that the client has not yet paid the builder. These are called “paid when paid” clauses, and they are unenforceable in Victoria. For you as a homeowner, this has a practical consequence worth understanding: the tradies working on your site, the concreters, framers, and electricians, are legally entitled to payment regardless of any dispute you might have with the head contractor. This means a financial disagreement between you and your builder cannot lawfully cascade down the supply chain and stop your project in its tracks through unpaid subcontractors. It is a protection that runs in everyone’s interest, and it is one reason working with a builder who manages subcontractor relationships transparently matters as much as the contract itself.
The Standard Progress Claim Stages for a Victorian New Home Build
Most Victorian new home builds follow a six-stage payment schedule, and understanding what each stage actually represents in physical construction terms is one of the most practical things you can do before signing a building contract.
The Six Standard Stages
Deposit (5% of the contract price) is paid before construction begins, typically at contract signing. Under Victorian law, the deposit is capped, and a builder cannot demand more than the legislated amount upfront. This payment secures your contract and covers pre-construction work such as council applications and engineering plans. No physical work on site needs to have occurred for this stage, but nothing beyond the capped deposit should leave your account before construction commences.
Base or Slab Stage (10%) is reached when the concrete slab and footings have been poured and cured. Before this claim is valid, underground drainage and plumbing beneath the slab must also be in place. As a homeowner, you should visually confirm the slab is poured, fully set, and free of visible cracking or settlement before releasing payment.
Frame Stage (15%) means the structural frame of the home is complete: wall frames erected and plumb, roof trusses in place, and structural beams installed. Watch your contract carefully here. Some builders modify the standard definition to allow claiming frame stage when framing is only “substantially complete” or when work on the next stage has already begun. That language is ambiguous and could require you to pay before the frame is genuinely finished. The frame should be inspected and verified as structurally sound before you release this payment.
Lock-Up Stage (35%) is the single largest payment in a standard Victorian contract. The home should be fully enclosed at this point: external walls complete, roof on, all windows installed and operational, and external doors fitted so the building is weatherproof and secure against entry. Because this payment represents more than a third of your total contract price, it warrants the most careful verification of any stage. Do not release this payment until you have physically confirmed every item that constitutes lock-up under your contract is in place.
Fixing Stage (25%) covers internal fit-out work: plasterboard linings, cornices, skirting boards, internal doors, kitchen cabinetry, bathroom fixtures, and similar finishes. Every item listed under fixing in your contract should be physically installed before this claim is paid.
Final or Completion Stage (10%) is triggered by practical completion, meaning all contracted work is done and the home is ready for occupation. This final 10% effectively functions as a retention payment, giving you leverage to ensure any defects identified during your pre-handover inspection are addressed before you hand over the last dollar.
Your Right to Inspect Before Paying
You have the right to inspect work at each stage before releasing payment. Use it. Engaging an independent building inspector at key milestones, particularly at frame and lock-up, is one of the most cost-effective decisions you can make during a build. An inspector will check things like wall plumb, engineer-specified connections, and whether all contracted elements are genuinely complete, not just partially done.
Why Your Specific Contract Definitions Matter
The percentages above reflect the standard Method 1 schedule under the Domestic Building Contracts Act 1995 (Vic), but builders can and do modify stage definitions in the Special Conditions of their contracts. A definition of frame stage that reads “substantially complete” instead of “complete” is legally weaker and financially riskier for you. Per Consumer Affairs Victoria, progress payments must follow the schedule set out in the contract, and builders cannot demand payment ahead of that schedule without your agreement. Reading every definition in your contract before signing is not optional; it is the difference between knowing your rights and finding out the hard way that you waived them.
How Progress Claims Work in Renovations and Extensions
Renovation and extension payment schedules operate differently from new home builds, and that difference matters more than most homeowners realise. In a standard new build, the construction sequence is largely linear. The slab goes down, the frame goes up, the roof is locked up, and the milestones follow each other in a predictable order. Renovations rarely work that way. Work often happens in stages across a partially occupied home, with trades moving between isolated zones, some areas completing while others remain untouched, and the homeowner living through the process. A generic six-stage payment schedule built for a new home simply does not map cleanly onto that reality.
This is where milestone language becomes critical. In a new build, terms like “lock-up” carry a broadly understood industry meaning. In a renovation, phrases like “completion of kitchen works” are dangerously vague unless the contract defines them precisely. Does it mean demolition is done? Joinery installed? Appliances connected? Tiling finished? Two parties can read the same clause and reach completely different conclusions, and that gap is where disputes start. Every milestone in a renovation contract should describe a visible, verifiable state of completion, not a process or a general stage of works.
Variations add another layer of complexity. In renovations, unforeseen conditions are common once walls open up: concealed structural issues, outdated wiring, materials that need removal before new work can proceed. These discoveries generate additional scope, and that scope sits outside the original payment schedule. Best practices for contractor payment schedules are clear on this point: variations must be documented in writing, with an agreed cost and a clear statement of how they will be billed, before the additional work begins. A variation agreed verbally on site and then bundled into a later progress claim, with no written trail, is one of the most common precursors to a payment dispute.
The most effective protection for a homeowner is straightforward: confirm in writing exactly what is included at each payment stage before the build starts. Not halfway through. Not after the first claim arrives. The Procore guide to progress payments describes the payment schedule as the financial framework that governs the entire project, and that framework needs to be solid from day one. Ask your builder for a written schedule of values that maps each payment to a defined scope of work, and confirm that both parties agree on what “completion” looks like at each stage.
At Builda Group, payment schedules for renovations and extensions are built around the actual scope of the job. The same template does not get applied to every project. A rear extension with new kitchen and bathroom works requires different milestone definitions than a structural alteration or a multi-room fitout, and the payment schedule reflects that from the outset.
Progress Claims in NDIS and Insurance Repair Works
Not all construction projects follow the same payment pathway, and two project types where this matters most are NDIS-funded accessibility modifications and insurance repair works. Both involve a third party sitting between the builder and the homeowner in the payment chain, and that changes how progress claims need to be structured, documented, and submitted.
NDIS-Funded Accessibility Modifications
In a standard residential contract, the payment relationship is straightforward: the builder completes a stage, submits a progress claim, and the client approves it. In NDIS-funded construction, that bilateral relationship becomes more complex. Funds are controlled by the NDIA, a registered plan manager, or a support coordinator, and a progress claim must satisfy that funding body before payment is released. The homeowner may agree the work is complete, but that agreement alone does not unlock the funds.
The documentation requirements reflect this dual audience. A progress claim in an NDIS project typically needs to demonstrate not only that a stage is physically complete, but that the completed work directly corresponds to the scope approved in the participant’s funding plan. Claims need to map to specific line items, and any variation between what was approved and what was built can trigger a review or delay. This means photo evidence, written stage sign-offs, and detailed cost breakdowns are not optional extras; they are the difference between a claim that gets paid and one that stalls.
Insurance Repair Works
Insurance-funded repairs operate under a similar logic. The insurer acts as the de facto funding body, and staged payments often require insurer sign-off at each milestone before the next tranche is released. In practice, this can mean a loss adjuster or insurer-appointed assessor verifying that the claimed stage meets the required standard before authorising the next payment. That approval layer simply does not exist in a private residential contract.
Across both sectors, well-structured progress claims in construction are not just a compliance formality; they are the primary tool for keeping a project moving without funding interruptions.
Builda Group works across both NDIS accessibility modifications and insurance repair works. That experience means familiarity with the documentation standards, approval workflows, and compliance expectations that these sectors require, so projects are not held up by avoidable claim deficiencies.
Your Rights When You Dispute a Progress Claim
Knowing your rights when a progress claim is disputed is one of the most practically important things you can do as a homeowner before a situation escalates. The short version is this: you can withhold a disputed amount when it is tied to a specific, documented issue, such as work that has not been genuinely completed or a defect that has been formally identified. What you cannot do is refuse payment in a blanket, undocumented way. That approach carries real legal and contractual risk, and it tends to weaken your position rather than strengthen it.
What You Can Withhold and Why Documentation Matters
The amount you withhold should correspond directly to the value of the incomplete or defective work. If a progress claim is submitted and part of the claimed stage has been completed but a portion has not, paying the undisputed portion while formally withholding the rest is a far more defensible position than refusing the entire claim. Before you withhold anything, document the specific problem in writing. Take dated photographs, note the exact items not completed or the defects identified, and if the issue is significant, commission an independent building inspection report. That written record becomes your evidence base for everything that follows.
How to Raise a Dispute in Writing
Once you have documented the issue, put your concerns in writing before withholding any payment. Verbal disputes are nearly impossible to rely on if the matter escalates, and legal guidance consistently points to this as the first place homeowners lose ground. Your written notice should clearly identify the specific issue, state what rectification is required, and set a reasonable timeframe for the builder to respond or remedy. Keep the language factual and specific. If you have a construction loan, notify your lender at the same time. Lenders typically require a progress inspection before releasing funds, and they need to know a dispute is active so they can apply their own protocols before any drawdown is approved.
Formal Dispute Resolution Pathways in Victoria
If written communication does not resolve the matter, Victoria provides three formal pathways.
Domestic Building Dispute Resolution Victoria (DBDRV) is the mandatory first step for most residential building disputes before proceeding to VCAT or court. Either party can apply, the process is designed to be accessible, and a conciliator works with both sides to reach a resolution. If conciliation does not succeed, DBDRV issues a Certificate of Conciliation, which allows either party to proceed to the next stage. It is worth understanding that home builder payment disputes in Victoria are already subject to significant delays, and proposed legislative changes may add further steps to this process.
VCAT is the primary formal tribunal for domestic building disputes once DBDRV has been attempted. It is a more structured legal process, and while it is more accessible than the Supreme Court, it can take a considerable amount of time to resolve and involves real costs. If you reach this stage, legal representation is strongly advisable.
Adjudication under BACISOPA is a faster, interim process designed to resolve payment disputes without full litigation. It is worth understanding, however, that BACISOPA’s application to residential owner-occupier disputes differs from commercial construction, and a builder generally cannot use SOPA adjudication directly against a residential homeowner client. The pathway for residential disputes runs through DBDRV and VCAT. Understanding this distinction matters because it shapes how both sides approach the dispute process.
Do Not Release Final Payment Until Everything Is Resolved
This is not a technicality. It is the single most important practical point in any building dispute. Your leverage as a homeowner is substantially greater while final payment is still outstanding. Once that payment is made, you move from a position of withholding to a position of recovery, which almost always means initiating formal proceedings. Walk through every outstanding defect and incomplete item with your builder before releasing the final claim, and get written confirmation that all agreed rectification has been completed. The recommended process for disputing a progress claim follows this same logic: resolve issues while you still hold the financial incentive, not after.
What Happens When a Builder Disputes a Withheld Payment?
When a homeowner withholds a progress payment, a builder is not without options. Under the Building and Construction Industry Security of Payment Act 2002 (Vic), known as BACISOPA, builders have statutory rights to pursue unpaid progress payments through a formal adjudication process. It is important to understand a key distinction in Victoria: BACISOPA adjudication cannot be used directly against a residential homeowner client. Where a dispute involves a residential owner, the builder must instead refer the matter to the Building and Plumbing Commission for dispute resolution, or pursue other legal remedies. BACISOPA adjudication is most commonly used between head contractors and subcontractors, or in commercial construction contexts. Either way, the existence of a structured, enforceable resolution pathway changes how both parties approach a dispute.
For disputes that do proceed through adjudication, the process is specifically designed to move faster and cost less than full litigation. Rather than waiting years for a court decision, adjudication provides an interim determination based on the documented evidence available at the time. Across Australian jurisdictions, the process from payment claim to adjudicator determination can be resolved in as few as approximately 35 business days in states like New South Wales and South Australia. The adjudicator’s determination is binding unless a party successfully applies to a court to have it set aside, which is only available in limited circumstances. This gives the process real teeth without requiring either party to engage in protracted legal proceedings.
One principle that runs through all of this is the prohibition on “paid when paid” clauses. Under BACISOPA, a builder or head contractor cannot withhold payment to subcontractors simply because the client has not yet paid them. This protection keeps cash moving through the full supply chain on your project, meaning the trades working on your home have legal recourse regardless of what is happening between you and the head contractor.
Understanding how a builder can respond to a withheld payment actually helps homeowners engage more constructively when issues arise. A builder holding a Domestic Builder Unlimited licence operates within a clear regulatory framework with enforceable rights and obligations running in both directions. That transparency is not a threat; it is a foundation for resolving disputes quickly and professionally, without the relationship deteriorating into costly legal conflict.
Practical Tips Before Releasing Any Progress Payment
The steps below are practical, low-cost, and directly reduce your financial risk at every payment milestone. None of them require legal expertise. They just require you to slow down before signing off.
Get an independent building inspector at the critical stages.
Do not rely solely on your builder’s confirmation that a stage is complete. A builder has a direct financial interest in releasing each payment promptly, which is not a criticism, it is simply the reality of how construction cash flow works. An independent building inspector has no such interest. Commission one at frame stage, at lock-up, and again prior to the final payment. These are the three milestones where defects are most likely to be present and most expensive to rectify if missed. Independent inspection is not an adversarial act; it is the standard model described across industry guidance, and a professional builder will not object to it.
Photograph everything before you release payment.
Take dated photographs of the site before approving each progress claim. Walk the site yourself if you can, or arrange for someone to do it on your behalf. Capture the specific elements the contract says must be completed for that stage. A photograph taken on the day of payment approval is a contemporaneous record that is very difficult to later dispute. This is one of the most practical risk-management steps available to any homeowner, and it costs nothing beyond a few minutes of your time. Industry best practice explicitly lists photographs as proof of work for exactly this reason.
Match the claim to your contract word for word.
Read the stage definition in your contract carefully, then check what is physically on site against it. Not approximately, exactly. If your contract defines lock-up as external doors and windows installed and secured, verify that before paying. If the claim references progress claim management software and arrives as a polished digital document, that professional presentation does not confirm the underlying work is complete. Contractors increasingly use automated tools to generate claims quickly; your review process should not move at the same pace.
Read the payment schedule before work starts, not after the first claim arrives.
Most disputes escalate because homeowners encounter the contract’s payment terms for the first time when a payment is already due. Read the payment schedule section at project commencement. Understand your cooling-off rights. Know the dispute process before you need it. That preparation alone prevents most payment conflicts from becoming formal disputes.
Know the red flags and pause when you see them.
Some patterns warrant stopping before you pay. A builder requesting payment before the contractual milestone has been reached is a clear signal to pause. Pressure to pay quickly without a site visit is another. An invoice that does not reference the specific stage being claimed is incomplete on its face and should be queried before payment is released. These are not rare edge cases; financial pressure in construction is well-documented, and it does influence how and when some builders submit claims. Recognising the pattern early puts you in a far stronger position.
Getting Progress Claims Right From the Start
Progress claims are a normal, well-regulated part of building in Victoria. The framework exists to protect both parties, and it works best when both parties understand it before construction begins. If you have read through this guide, you are already better prepared than most homeowners who encounter their first progress claim mid-build and start asking questions under pressure.
The protections available to you are real and layered. Consumer Affairs Victoria oversees domestic building contracts and the payment schedules within them. BACISOPA gives you formal adjudication rights if a payment dispute cannot be resolved directly. The Building Legislation Amendment (Fairer Payments on Jobsites and Other Matters) Bill 2025 introduced landmark reforms that took effect in April 2026, tightening obligations on all contracting parties. And formal dispute pathways through VCAT remain available when direct resolution fails.
A builder worth working with will walk you through the payment schedule before you sign anything, not after the first claim arrives. That transparency is not a courtesy; it is a signal of how the entire project will be managed.
