Home building warranty insurance in WA: what is covered if your builder cannot finish

Perth’s building sector has seen its share of builder insolvencies in recent years, which has made home indemnity insurance a topic more buyers ask about upfront rather than assume is sorted. This is general information about how the cover typically works, not advice for a specific claim; a solicitor or the Building Commission can guide you through an actual dispute.

What home indemnity insurance actually is

In WA, builders working on residential contracts over a set value are generally required to hold home indemnity insurance before they can demand payment beyond an initial deposit. The cover exists to protect you, the homeowner, if the builder dies, disappears, or becomes insolvent and cannot complete the contracted work or fix structural defects within the cover period, which typically extends for several years after completion for structural issues.

It is easy to assume this insurance protects you against a bad build generally. It does not. If your builder remains in business and simply does substandard work, your recourse sits with the builder directly, through the defects liability process in your contract, or through the Building Commission and, if needed, the State Administrative Tribunal. Home indemnity insurance is specifically a safety net for the builder disappearing from the picture entirely.

What it covers versus what it does not

Situation	Typically covered	Typically not covered
Builder dies or disappears mid-build	Yes	No
Builder becomes insolvent, cannot finish	Yes	No
Structural defect found after handover, within cover period	Yes	No
Builder is trading but does poor-quality work	No	Yes, use contract remedies instead
Cosmetic issues like paint touch-ups	No	Yes, handled under defects liability period
Delays or cost overruns while builder remains solvent	No	Yes, this is a contract dispute, not an insurance claim

Checking your cover before you commit

Ask your builder for the certificate of insurance before making any payment beyond the deposit, and confirm the policy is active and matches the contract value. This is a reasonable, normal request, and a builder confident in their financial position should have no issue providing it. If a builder is reluctant to show proof of cover, treat that as a serious concern rather than a minor administrative gap.

It is also worth checking a builder’s registration status with Building and Energy WA directly, since registration and insurance requirements work together as part of the same consumer protection framework. A builder who is properly registered and insured has more to lose by cutting corners than one operating outside that system.

What to do if things go wrong

If your builder becomes insolvent mid-build, contact your insurer promptly to understand the claims process, since documentation requirements and timeframes differ by insurer and situation. This can be a stressful, complex process, particularly if you are also managing an unfinished home and ongoing rent or mortgage payments, so getting advice from a solicitor experienced in building disputes is worth the cost for anything beyond a straightforward claim.

Choosing a builder with a strong, consistent track record reduces the odds you will ever need this cover in the first place. Reviews that mention delivery reliability and a consistent trading history over several years are worth weighing alongside price when you shortlist a builder.

How this differs from a defects warranty

It helps to keep home indemnity insurance separate in your mind from the defects liability period written into your building contract. The defects liability period is a builder’s direct obligation to fix issues within a set window after handover, while home indemnity insurance only steps in if the builder itself is no longer able to meet that obligation, due to death, disappearance or insolvency. A builder who remains in business is expected to resolve defects under the contract directly; the insurance is a backstop for the scenario where that is no longer possible.

Keeping your paperwork organised from day one

From the moment you sign a contract, keep a dedicated file, physical or digital, with your contract, insurance certificate, payment records, and any correspondence about variations or defects. This habit costs little effort during a build that is going smoothly, but it becomes genuinely valuable if you ever need to lodge an insurance claim or pursue a dispute, since insurers and tribunals generally expect documented evidence rather than a verbal account of what was agreed.
