Nearly 4,900 construction businesses collapsed across Australia in the last financial year — and construction now accounts for roughly one in every four business insolvencies nationally. If you're mid-build or about to sign a building contract in Melbourne, that statistic isn't abstract: it's the reason your progress payment schedule, your lender's drawdown process and your Domestic Building Insurance certificate deserve far more scrutiny than most first-time builders give them. This guide explains exactly what happens to your construction loan if your builder goes under, where Victoria's insurance safety net falls short, and how a broker structures your loan to protect you from the outset.
At Integrated Finance Group, we structure construction loans for Melbourne and Geelong clients every week, and builder risk is a conversation we now have with every single one of them — not because we want to alarm anyone, but because the protections available are genuinely underused simply because most borrowers don't know they exist until it's too late.
Quick answer: If your builder becomes insolvent mid-construction, you remain liable for whatever your lender has already drawn down, and you'll need to engage a new builder to complete the works. Victoria's Domestic Building Insurance (DBI) can cover part of the gap between what you paid and what was actually built, but it's capped at $300,000 per claim — which can fall short on a modern $700,000–$900,000 Melbourne build. The single biggest protection available to you is a construction loan structured so the lender only releases funds against independently verified, completed stages.
Why Are So Many Melbourne Builders Collapsing Right Now?
The current wave of builder insolvencies traces back to fixed-price contracts signed before and during the pandemic, when many builders locked in prices based on 2020–2021 material and labour costs. As those costs rose sharply through 2022 and 2023, thousands of Victorian builders found themselves contractually obligated to complete homes at prices that no longer covered their own costs — in some cases more than $100,000 underwater on a single build. Porter Davis Homes, once one of Victoria's largest volume builders, collapsed on 31 March 2023, leaving more than 1,700 homes incomplete nationally and becoming the largest single builder failure in the state's history. It was a turning point that prompted the Victorian government to reform aspects of the DBI scheme, but the underlying pressure on fixed-price building contracts hasn't disappeared — it has simply spread across a wider base of smaller and mid-sized builders since.
For anyone signing a new building contract in 2026, the practical lesson isn't to avoid building — it's to understand exactly what protections apply to your specific contract and loan, and to structure your finance so a builder collapse doesn't leave you personally exposed for the full shortfall.
What Actually Happens to Your Construction Loan If Your Builder Collapses?
Your loan agreement is with your lender, not your builder — so a builder's insolvency does not cancel or reduce what you owe. If your builder collapses partway through the build, three things typically happen in sequence: construction stops, you lodge a claim under your Domestic Building Insurance policy for any shortfall between what you paid and what was actually completed, and you then need to engage a new builder — usually at a higher cost than your original contract, since a second builder is pricing to finish someone else's partially completed work, not to build from scratch.
This is where loan structure becomes critical. A construction loan is drawn down in stages — typically base, frame, lock-up, fixout and completion — with your lender releasing funds at each stage rather than handing over the full loan amount upfront. If your lender (or your broker, on your behalf) requires an independent inspection confirming each stage is genuinely complete before releasing the next drawdown, you're protected from paying for work that was invoiced but never actually done. If your loan simply releases funds against the builder's invoice with no independent check, you carry significantly more risk if that builder is already in financial trouble.
Does Domestic Building Insurance Actually Cover You If a Builder Goes Under?
Victoria's Domestic Building Insurance (DBI) is mandatory for any residential building work over $16,000, and it's designed to step in when a builder dies, disappears, becomes insolvent, or has their licence cancelled and they can't or won't fix a problem. But the cover has real limits that most first-time builders don't discover until they need to make a claim.
| DBI Cover Element | Limit | What This Means for You |
|---|---|---|
| Total claim cap | $300,000 per claim | The maximum DBI will ever pay, regardless of your build's total value |
| Incomplete works | Up to 20% of the contract price | On a $750,000 build, that's a maximum of $150,000 — often less than what's needed to engage a second builder mid-project |
| Structural defects | Covered for 6 years post-completion | Longer-tail protection once the home is finished and habitable |
| Non-structural defects | Covered for 2 years post-completion | Shorter window — applies to fixtures, finishes and non-structural items |
The gap most Melbourne borrowers don't see coming is this: the median new house-and-land build in Melbourne's growth corridors now regularly sits between $700,000 and $900,000 once land, build and site costs are combined. Twenty percent of a $750,000 contract is $150,000 — but replacing a collapsed builder mid-build commonly costs more than that, because the second builder is pricing to inherit an unfinished, non-standard job, complete with whatever defects or shortcuts the first builder may have left behind. This is a detail few competitor guides walk through in practical dollar terms — most simply state the $300,000 cap exists without explaining how far short it can fall on a genuinely modern Melbourne build budget.
How Much Deposit Can a Builder Legally Ask For in Victoria?
Under the Domestic Building Contracts Act 1995 (Vic), a builder cannot request more than 10% of the contract price as a deposit before any work has started, for contracts over $20,000. This rule exists specifically to limit how much of your money is exposed if a builder collapses before a single spade goes into the ground. If you're asked for a deposit larger than 10%, or asked to pay for a later stage before it's actually complete, those are both signals worth raising immediately — with your broker, your conveyancer, or Consumer Affairs Victoria if the builder won't explain the request satisfactorily.
- Check the DBI certificate before you sign — not just before slab-down. A valid Certificate of Insurance should be provided prior to any deposit being paid.
- Search the Victorian Building Authority's public register for the builder's licence status and any current disciplinary notices or complaints.
- Be cautious of quotes significantly below competitors — this was a common thread across several of the 2023–2025 Victorian builder collapses, where fixed prices simply weren't sustainable against actual build costs.
- Ask for recent, verifiable references from clients who completed a build in the last 12 months, and actually call them.
How a Broker Structures Your Construction Loan to Limit Your Exposure
This is the part of construction lending that rarely gets explained clearly, because it happens behind the scenes between your broker, your lender and the valuer — but it's arguably the most important protection you have beyond DBI itself. When we arrange a construction loan, we work with lenders whose progress payment process requires an independent valuer or inspector to confirm each stage is genuinely complete before authorising the drawdown, rather than releasing funds purely against a builder's invoice or claim of completion. We also review your building contract's payment schedule against industry-standard stage percentages before you sign, so you can flag any stage where a builder is asking for a disproportionately large payment relative to the work actually involved at that point.
None of this eliminates the risk of a builder collapse entirely — no lender or broker can guarantee that — but it meaningfully reduces how much you stand to lose if it happens, by ensuring your loan funds only ever pay for work that's actually been done and verified. If you're comparing construction loan options or already have a signed building contract, our construction loans team can review the payment schedule and lender drawdown process with you before you commit.
Local context: Melbourne's outer growth corridors — including areas within IFG's own service footprint around Melbourne's north and west — have carried a disproportionate share of Victoria's new house-and-land construction activity over the past three years, which is exactly where fixed-price builder exposure has been most concentrated. If you're building in a growth corridor estate, it's worth asking specifically whether your builder's DBI provider has had recent claims activity, which your broker or conveyancer can help you look into.
What Should You Do If Your Builder Has Already Shown Warning Signs?
If your builder has gone quiet, missed a scheduled stage without explanation, or asked for payment out of sequence with the contracted stages, don't wait for a formal insolvency announcement before acting. Contact your lender to pause any pending drawdown request until the stage is independently verified, request an updated timeline in writing from the builder, and speak with your broker about your DBI position and what a stage-by-stage cost-to-complete might look like if you did need to switch builders. Acting early, even if the builder ultimately does complete the job, costs you nothing — waiting until after a formal collapse significantly narrows your options.
Frequently Asked Questions About Builder Insolvency and Construction Loans
What happens to my construction loan if my builder goes insolvent?
Your loan obligation to the lender does not disappear if your builder collapses — you still owe whatever has been drawn down so far. What changes is that you now need a new builder to complete the works, and Victoria's Domestic Building Insurance (DBI) may cover part of the shortfall between what you paid and what was actually built, up to a $300,000 cap. This is exactly why the progress payment structure on your loan matters so much before you sign — a broker can help ensure your lender only releases funds that match completed, inspected work.
Does Domestic Building Insurance cover the full cost if my builder collapses?
Not necessarily. Victoria's DBI is capped at $300,000 per claim, with incomplete works covered up to 20% of the contract price. On a $700,000 to $900,000 build — increasingly common in Melbourne's outer growth corridors — that cap can fall well short of what's needed to finish the home if a builder collapses mid-construction. Structural defects are covered for 6 years and non-structural defects for 2 years after the works are deemed complete, but the incomplete-works component is the one that catches owners out.
How much deposit can a Victorian builder legally ask for upfront?
Under the Domestic Building Contracts Act 1995 (Vic), a builder cannot ask for more than 10% of the contract price as a deposit before any work begins on a major domestic building contract over $20,000. If a builder is asking for more than 10% upfront, that is a warning sign worth raising with your broker and, if necessary, Consumer Affairs Victoria before you sign anything.
How do I check if a builder is at risk of insolvency before I sign a contract?
Ask for the builder's Domestic Building Insurance certificate before signing (not just before slab), check the Victorian Building Authority's public register for any current disciplinary actions or notices, request recent client references you can actually call, and be cautious of any builder offering a fixed price significantly below competitors — this was a leading indicator in several 2023–2025 Victorian builder collapses, where builders had locked in unsustainable fixed-price contracts during a period of rapid material and labour cost inflation.
Can a mortgage broker help protect me if my builder becomes insolvent mid-build?
Yes. A broker who specialises in construction lending structures your progress payment schedule so the lender only releases funds against independently inspected, completed stages — not simply because the builder has invoiced you. This progress-payment discipline is one of the few protections available to you beyond DBI, and it's a detail many first-time construction loan borrowers don't know to ask about until something goes wrong.
