What happens if a builder goes broke during construction?

A builder going broke partway through your build is the nightmare scenario every building client quietly worries about, and with several builder collapses in recent years, it is a fair concern. The reassuring news is that there is a mandatory safety net designed for exactly this. The important news is that it has limits, so understanding both is how you protect yourself.

There is a mandatory safety net

Across Australia, builders are required by law to take out builder warranty or indemnity insurance for residential work above a value threshold. This insurance protects the homeowner if the builder dies, disappears or becomes insolvent before completing the work, and in some cases if they lose their licence. The builder takes out the policy in your name, and the cost is built into your contract.

What it is called in your state

It goes by different names depending on where you build. It is building indemnity insurance in South Australia, domestic building insurance in Victoria, home building compensation cover in New South Wales, home warranty insurance administered through the building commission in Queensland, and home indemnity insurance in Western Australia, among others. The protection is broadly similar, but the rules and thresholds differ by state.

What it covers

The cover generally protects you for loss of deposit and the cost of completing incomplete work, and in many cases for rectifying certain defects, but only where the builder has died, disappeared or become insolvent. In practice that can mean the policy helps fund a new licensed builder to finish the home in line with the original contract.

South Australia specifically

In South Australia the cover is building indemnity insurance, which is mandatory for residential building work that requires development approval and is valued above the threshold, lifted to 20,000 dollars from 10 November 2025. The policy, issued in the homeowner name, covers non-completion up to a maximum of 250,000 dollars where the builder dies, disappears or becomes insolvent, an increase the state government made in response to recent builder collapses. Claims for defective work can generally be made up to five years after completion. You can check that a policy is valid through the official building indemnity insurance channels.

What it does not cover

This is widely misunderstood: builder warranty insurance is not a general quality guarantee. It does not help you if your builder is still a functioning, licensed business but simply refuses to fix a problem. It is insurance against the builder dying, disappearing or becoming insolvent, not against poor workmanship by a builder who is still trading. For ordinary disputes with a working builder, you rely on the contract and your state consumer protections instead.

The cap matters

The cover is capped, for example up to 250,000 dollars in South Australia, so on a larger build the insurance may not cover the full cost to complete. That is not a reason to dismiss it, it is a genuine and valuable safety net, but it is a reason not to treat it as unlimited protection. Choosing a financially sound builder in the first place remains your best defence.

What to do if your builder fails

If you suspect your builder has become insolvent, act promptly. Confirm the situation, contact the insurer named on your policy to begin a claim, and seek advice on engaging a new licensed builder to complete the work in line with your contract. There are time limits on claims, so the sooner you act the better, and keeping good records of payments and progress throughout the build makes any claim far smoother.

Protect yourself before it happens

Prevention beats cure. Before you pay anything, check that a valid builder insurance policy is in place for your build. Choose a builder with a solid financial track record, do not pay ahead of the work actually completed, and keep your progress payments matched to genuine progress. These steps, alongside the insurance, are how you turn builder insolvency from a catastrophe into a setback you can recover from.
