HBCF is the NSW scheme - in SA the compulsory cover is Building Indemnity Insurance (BII). What it covers, what it doesn't, and how to verify a builder is actually insured.

Builder-insolvency insurance is state based. NSW has HBCF (Home Building Compensation Fund), Victoria has Domestic Building Insurance (DBI), and South Australia has Building Indemnity Insurance (BII) under the Building Work Contractors Act 1995. If you are building in Adelaide, BII is the scheme that applies to you.
Non-completion if the builder becomes insolvent, dies or disappears mid-build, plus rectification of defective work by that builder, up to $250,000 per dwelling (increased from $150,000 on 10 November 2025). Structural defects are covered for 5 years from completion and non-structural defects for 2 years.
Cosmetic defects, damage caused by owner-supplied materials or trades, delays or variations you agreed to, disputes about workmanship where the builder is still trading and disputing your claim, and any work you contracted directly with subbies outside the head contract.
Ask the builder for the certificate of insurance for your specific project - it is issued per project, not per builder. Cross-check the ABN on the certificate against the contract, and confirm the cover matches your contract value. If the certificate is missing, expired, or lists a different address, do not pay a deposit.


The collapse of Bathla Group has left thousands of buyers facing uncertainty and raises an important question for anyone building a home: what actually happens if your builder goes under? In this episode, we explain the critical differences between a developer collapse and a builder collapse, how Victoria's new Home Warranty scheme works, and the practical steps every homeowner can take to protect themselves.
Watch full episodeYes. Most residential building work over $20,000 in SA (the threshold rose from $12,000 on 10 November 2025) legally must have Building Indemnity Insurance under the Building Work Contractors Act 1995. The builder must hold the certificate before starting work. Building without it is an offence and voids the homeowner's statutory protection.
Yes. New build, knockdown rebuild, extension, major renovation or granny flat - if the work needs development approval and is over the threshold, Building Indemnity Insurance is required. Ask for the certificate regardless of project type. Owner-builder work is separately regulated.
The builder arranges the policy through a registered insurance broker with an eligible insurer (for example QBE or Assetinsure) and passes the premium through the contract. It is a legal cost, not a variation - do not pay a builder who bills it separately as a "compliance surcharge".
Structural defects are covered for 5 years from the date of practical completion, and non-structural defects for 2 years. Non-completion cover applies during the build. Keep the certificate, the contract and the practical-completion certificate together - you will need them if you ever claim.
