What Is Home Warranty Insurance?
Home warranty insurance is a statutory insurance scheme attached to residential building work that protects the homeowner, not the builder, if the builder dies, disappears, becomes insolvent, or has their licence suspended and cannot finish or rectify defective work. It goes by a different name in different Australian states and territories — for example the Home Building Compensation Fund (HBCF) in New South Wales and Domestic Building Insurance (DBI) in Victoria — and exactly when it is required and what it covers varies by state and changes from time to time, so always check the current rules with the relevant state regulator.
Key takeaways
- Home warranty insurance protects the homeowner, not the builder, if the builder cannot complete or fix residential work due to death, disappearance, insolvency or licence suspension.
- It is a state-based statutory scheme, so the name, the trigger threshold and the exact cover differ across New South Wales, Victoria and the other states and territories.
- It typically applies to residential building work above a contract value threshold set by each state — check the current figure with that state’s regulator rather than relying on a remembered number.
- It sits alongside, not instead of, contract works insurance, which covers the physical building work while it is under construction.
What home warranty insurance is
Home warranty insurance is a statutory scheme that protects a homeowner on residential building work if something goes wrong with the builder rather than the building — specifically if the builder dies, disappears, becomes insolvent, or has their licence suspended or cancelled, and as a result cannot complete the contract or fix defective work.
It is not a general defects warranty and it is not held by the builder for their own benefit. It exists to give the homeowner somewhere to turn when the builder themselves is no longer available to put things right.
Different names in different states
Home warranty insurance is administered state by state in Australia, so it goes by different names and sits with different regulators depending on where the work is being done.
- New South Wales — Home Building Compensation Fund (HBCF).
- Victoria — Domestic Building Insurance (DBI).
- Other states and territories run their own equivalent schemes, each with its own name, threshold and administering body.
Check current rules
Thresholds, premiums and exactly what is covered change over time and differ by state — this page is general information, not legal or insurance advice. Confirm the current requirements with your state’s fair trading or building regulator before relying on any figure.
When it is typically required
Most states require home warranty insurance for residential building work once the contract value passes a threshold set by that state, with some exemptions for owner-builders or particular types of work.
The trigger is usually the contract value rather than the type of job, so a modest renovation can fall under the threshold while a similar-sized new build does not, depending on how each state defines the work.
Because thresholds, exemptions and premiums are set and revised by each state government and change from time to time, this page deliberately does not quote a specific dollar figure — check the current requirement with the relevant state regulator or an insurance broker before pricing or signing a residential contract.

Frequently asked questions
What is home warranty insurance?
Home warranty insurance is a statutory insurance scheme for residential building work that protects the homeowner if the builder dies, disappears, becomes insolvent or has their licence suspended and cannot complete or fix the work.
Is home warranty insurance the same in every state?
No. It is administered separately by each Australian state and territory, so the name, the contract value threshold and the exact cover differ, for example HBCF in New South Wales and DBI in Victoria. Check the current scheme in your state.
Who does home warranty insurance protect?
It protects the homeowner, not the builder. It is designed to give a homeowner recourse if the builder themselves, rather than the building, becomes the problem, through death, disappearance, insolvency or licence suspension.
Is home warranty insurance the same as contract works insurance?
No. Contract works insurance covers the physical building work against damage while it is under construction. Home warranty insurance is a separate statutory scheme protecting the homeowner if the builder cannot complete or rectify the work. Many residential projects need both.
