What home warranty insurance doesn't cover

What home warranty insurance actually is

Home warranty insurance — called domestic building insurance in Victoria, home indemnity insurance in Western Australia, and residential building insurance in some other states — is a form of insurance that protects homeowners if their builder dies, disappears, or becomes insolvent before completing the work, or within a set period after completion.

In most states, builders are required by law to take out this insurance on your behalf for residential building work over a certain value (the threshold varies by state). A certificate of currency should be provided to you before work begins.

What it covers — in the best case

If your builder becomes insolvent, dies or disappears, home warranty insurance typically covers:

• The cost of completing the work (up to the insured amount)
• Rectification of defects discovered after completion, where the builder cannot be compelled to fix them
• Loss of deposit in limited circumstances

Sounds reassuring. But the conditions attached to each of these are significant.

What it does not cover

The following are among the most common situations homeowners assume they are protected against — and are not:

Disputes while the builder is still alive and trading

If your builder is still in business — even if they have abandoned your project, produced defective work, or refused to respond to your calls — you generally cannot access home warranty insurance. The insurer will wait until the builder is formally insolvent, has died, or has disappeared. This is the gap that catches most homeowners.

Defects that appear after the warranty period

Cover for defects is time-limited. Structural defects are typically covered for six years from completion in most states; non-structural defects may only be covered for two. Defects that appear after this period are your problem.

Work carried out without a required permit

If your builder has carried out work without the required building permits, your insurer may void or significantly limit your claim. Always ensure permits are in place before work begins.

Unlicensed builders

If your builder does not hold the appropriate current licence for the work carried out, your home warranty insurance may be void entirely. This is one of the most serious consequences of hiring an unlicensed operator.

What to do about the gaps

Home warranty insurance was never designed to replace due diligence — it was designed to be a final safety net in the worst circumstances. The real protection happens before you sign a contract:

1. Check the builder's licence on the relevant state register — free, and takes 30 seconds
2. Order a background report covering financial history, court records and dispute history before you commit
3. Verify the insurance certificate independently before any work begins
4. Have a solicitor review the contract before you sign it
5. Understand the deposit cap in your state and do not pay above it regardless of what the builder requests

Home warranty insurance provides meaningful protection in genuine catastrophic cases. But the homeowners who need to claim on it are almost always those who skipped the due diligence steps above.
