Home Warranty and Latent Defect Insurance for Australian Residential Builders
Home Warranty Insurance (HWI) — also known as Home Building Compensation or Builders Warranty in different states — is a statutory cover required for residential building work above a set contract value in NSW, SA, WA, and ACT. It protects homeowners if the builder dies, disappears, becomes insolvent, or fails to rectify defects. Latent Defect Insurance (LDI) is a complementary multi-year cover that protects the building itself against structural defects discovered post-completion.
Silverback Insurance Brokers works with Home Warranty distributors and specialist insurers depending on the state, helping residential builders secure HWI eligibility, manage project-by-project certificates, and arrange LDI on mid-rise and strata developments.

Latent Defect Insurance (LDI) — for Developers and Owners

Home Warranty & Latent Defect Insurance FAQs
Which states require home warranty insurance in Australia?
Home warranty insurance is required for residential building work above specified thresholds in New South Wales (icare HBCF), South Australia, Western Australia, and the Australian Capital Territory. These are broker-placed states where Silverback can arrange cover directly. Victoria (BPC) and Queensland (QBCC) operate government-direct schemes.
What does home warranty insurance protect?
Home warranty insurance protects homeowners if the builder dies, disappears, becomes insolvent, or fails to rectify defective or incomplete work. It is a statutory consumer protection — not insurance for the builder's benefit, though it is the builder's responsibility to obtain it before commencing work.
What is latent defect insurance and how is it different from home warranty?
Latent defect insurance (LDI) is a 10-year post-completion policy that covers structural, mechanical, electrical, plumbing, fire safety, facade, and waterproofing defects discovered after an occupancy certificate is issued. Unlike home warranty (which covers builder failure), LDI covers the building itself on a strict-liability, first-resort basis — the property owner or strata body claims directly without needing to prove fault.
What building types are eligible for latent defect insurance?
LDI is available for Building Classes 2 through 9 (residential apartments, commercial, industrial, and mixed-use) with a construction value above $2 million. A Technical Inspection Service (TIS) must be engaged from the design phase to monitor construction quality throughout the build.
How much does latent defect insurance cost?
LDI premiums typically range from 1.4% to 1.7% of the total construction value, with an average around 1.55%. The premium is usually structured as 30% payable at construction commencement and 70% at occupancy certificate. The sum insured covers 100% of the construction value with 3% annual indexation.
