Home Warranty Insurance

The builder usually pays for home warranty insurance, but it doesn't always protect you for unfinished jobs.

Homeowners who are left with incomplete or defective construction jobs may be protected by mandatory home warranty insurance in many parts of Australia – but only if the builder has gone missing, passed away, become insolvent or lost their licence.

This type of insurance is purchased by the builder doing the work and has many different names depending on the state you live in.

What is home warranty insurance?

Home warranty insurance is designed to protect homeowners against incomplete building work and defects from construction in residential projects but it only covers you in specific situations. For example, if your builder:

  • Goes missing
  • Dies
  • Becomes insolvent
  • Loses their license

It's taken out by the builders and tradespeople themselves but is only mandatory when the build project reaches a certain value. This differs between states, as does what it's called.

Home warranty insurance in NSW and WA

Home warranty insurance functions largely the same way in both NSW and WA. The main difference is that it's often called "home building compensation" in NSW and "home indemnity insurance" in WA. It can cover you for the completion of building work or fixing defects but only if:

  • The builder is unable to finish the work due to death, financial insolvency or disappearance within six years of finishing the contract.
  • Any builder or tradesperson is required to take out this insurance for each building project over $20,000. Sub-contractors are covered by the head contractor's cover.

Home warranty insurance in other states like ACT, SA and TAS

Home warranty insurance is mandatory in South Australia, the ACT and the Northern Territories for projects above $12,000 but not in Tasmania. It covers homeowners for incomplete construction and structural defects in a similar way to other states. It can apply if

Pros and cons of home warranty insurance


  • It can sometimes cover incomplete or defective building work.
  • It can be an effective "last resort" system, where you can claim only if the builder doesn't complete the work due to death, disappearance or financial insolvency.


  • It's only mandatory on residential building projects that exceed a certain threshold depending on the state.
  • It doesn't protect you from dishonest builders (you generally won't be covered if a builder refuses to repair their work or give you a refund.)
  • In-built cap regardless of the building project (you'll only be covered for a maximum of 20% of the contract price).
  • It won't cover commercial buildings.
