HBC Insurance in NSW: What Every Homeowner Should Know Before Renovating
Most homeowners have heard the term HBC insurance thrown around without anyone properly explaining what it means for them. If your NSW bathroom renovation comes in over $20,000, your contractor is legally required to hold it — and they must hand you the certificate before you pay a cent.
Not after. Before. If that hasn’t come up in your conversations with a contractor yet, it needs to.
What Is HBC Insurance?
Home Building Compensation insurance — HBC insurance, or what used to be called Home Warranty Insurance — is a mandatory protection scheme run by the NSW State Insurance Regulatory Authority (SIRA). It’s been part of the residential building landscape in various forms since 1997. The core purpose is simple: if a licensed contractor can’t finish the job or won’t fix problems with their work, HBC insurance gives you a financial path forward.
But it’s a last-resort policy, and that distinction matters. It’s not a general guarantee of quality. It doesn’t kick in because you and your tradie had a falling out over grout colour. It activates when something has gone seriously wrong — specifically when a contractor has died, disappeared, or become insolvent and can no longer complete or rectify their work.
SIRA administers the scheme and runs the public register of licensed contractors. Every certificate is tied to a specific project, a specific licence number, and a specific contract value. That’s what makes it verifiable — and what makes the document meaningful rather than ceremonial.

When Is HBC Insurance Required in NSW?
The trigger is a contract value over $20,000 (GST included) for residential building work. Bathroom renovations — once you factor in waterproofing, tiling, plumbing, a new vanity, shower screen, and fixtures — regularly sit well above that mark. A $22,000 quote means HBC insurance is required, full stop.
The threshold applies to the total contract. Not just labour. Not just materials. The whole thing. The obligation sits with the contractor, not the homeowner. You don’t arrange it, you don’t pay for it separately — they do, under the Home Building Act 1989 (NSW). And the timing is non-negotiable: the certificate has to be in your hands before the contractor accepts your deposit. Not when work starts. Not with the contract paperwork. Before your money moves.
Important: Contractors taking deposits without providing the certificate aren’t being a bit disorganised — they’re in breach of NSW law. Once money has changed hands, your leverage drops considerably.

What Does HBC Insurance Actually Cover?
Cover only activates under three specific circumstances. The contractor has to have died, disappeared, or become insolvent. These are the trigger events. Without one of them, HBC insurance isn’t in play regardless of how badly the job has gone.
If the contractor dies before completing the work or rectifying defects, the policy activates and covers the cost of completion or rectification by another licensed contractor.
If the contractor can’t be located and there’s no reasonable prospect of them returning to finish or fix the work. More common than most people expect — and exactly the scenario HBC insurance exists for.
If the contractor goes bankrupt, enters administration, or has their company wound up before completing or rectifying work. The policy covers the gap.
When a trigger occurs, the policy covers the cost of completing unfinished work and rectifying defective work. Time limits apply. For defects that aren’t structural, you have two years from the trigger event to make a claim. For major defects — and in bathrooms that can mean things like structural waterproofing failures under AS3740 — you have six years. Those windows close whether you’ve discovered the problem or not, so keep your paperwork.
What HBC insurance won’t cover: disputes while the contractor is still operating and accessible. If the work is poor but the tradie is still in business and picking up the phone, that’s a matter for NSW Fair Trading or the NSW Civil and Administrative Tribunal (NCAT). HBC insurance doesn’t step in just because you’re unhappy.

What You’re Entitled to Before Work Starts
Before any deposit changes hands, you’re entitled to a valid HBC insurance certificate specific to your project. Not a generic document from a previous job. Not a screenshot pulled up on a phone. A certificate that shows your property address, the contract value, your contractor’s licence number, and the period of cover.
Issued by an approved insurer
icare is currently the approved insurer in NSW. Verify this is still current at the time of your renovation.
Your name and property address appear on it
Not a generic document from a previous job. Your address, your project.
Contract value matches your quote
The figure on the certificate must match the quoted contract value. A discrepancy is a problem worth raising.
Contractor’s licence number is visible
Cross-reference this against the SIRA register before paying anything.
Dated and shows the period of cover
An undated certificate or one with an expired cover period isn’t valid. Check both.
Contractor verifiable on SIRA register
Takes two minutes at onlineregister.fairtrading.nsw.gov.au. A licence that doesn’t appear isn’t valid.
From there, two minutes on SIRA’s online register at onlineregister.fairtrading.nsw.gov.au will confirm whether that licence is current and in good standing. It’s a quick check and there’s no good reason not to do it.
Note: If a contractor tells you the certificate will come through later — after you’ve signed, once the job gets underway — that’s not an admin delay. That’s them skipping a statutory obligation.
What If Your Contractor Doesn’t Have HBC Insurance?
Don’t pay the deposit.
Operating on a project over $20,000 without valid HBC insurance is a breach of the Home Building Act 1989. There’s no grey area in that. And once money has changed hands, your leverage drops considerably.
⚠️ They claim the job is under $20,000 when the scope clearly isn’t
Get an itemised breakdown. If the total clears $20,000 once everything is included, the threshold is met regardless of what they say.
⚠️ They can’t produce the certificate before asking for a deposit
That’s the moment to stop. No certificate before payment means no payment.
⚠️ The certificate doesn’t match your address or quoted contract value
A certificate issued for someone else’s property or a different job isn’t valid for yours. Check every field.
⚠️ Their licence comes up expired or suspended on the SIRA register
If the registration isn’t current, HBC insurance can’t be validly issued in their name.
Already paid before you thought to check? Contact NSW Fair Trading straight away. They can investigate and take enforcement action in some cases. But you’re in a much better position if you catch it before the deposit rather than after — which is why it’s worth checking upfront, every time.

Important: A contractor who becomes evasive when asked for their HBC certificate or SIRA licence number has already given you the most important piece of information you need.
HBC Insurance vs. Public Liability Insurance
This one comes up constantly, and it’s a genuine point of confusion. When you ask a contractor about HBC insurance, a lot of them will pivot to talking about their public liability cover — and those two things are completely different.
Covers property damage or injury caused by the contractor during the works. If a plumber floods your neighbour’s bathroom, public liability is what responds.
About incidents on site — not the job itself.
Protects you if the contractor can’t complete or rectify their work because they’ve died, disappeared, or gone insolvent. Nothing to do with incidents during the job.
About the job itself — not individual site incidents.
You need both. A contractor holding public liability cover but no HBC insurance for a $25,000 bathroom renovation is not compliant — they’re just insured for a different set of risks. Don’t accept one as a substitute for the other.

Common Questions
Not all — but most. HBC insurance is required when the total contract value exceeds $20,000 (GST included). Given what a full bathroom renovation typically costs in NSW, that threshold gets crossed more often than not. Check before you sign anything.
The contractor. It’s their obligation under the Home Building Act 1989 (NSW) and it can’t be passed to the homeowner or waived. If a contractor suggests otherwise, that’s a red flag worth paying attention to.
Before they accept any deposit from you. Not at contract signing, not when work starts — before your money moves. That’s the legal requirement, and it’s worth holding them to it.
Pull up the SIRA online register at onlineregister.fairtrading.nsw.gov.au and search using their licence number. It’ll show whether the licence is current and in good standing. Takes two minutes and there’s no good reason not to do it.
Incomplete work and defective work — but only if the contractor has died, disappeared, or become insolvent. For non-structural defects (tiling, fixtures, finishes), the claim window is 2 years from the trigger event. For major structural defects, it’s 6 years. Those windows close whether you’ve discovered the problem or not, so keep your paperwork.
Public liability covers damage or injury caused by the contractor while they’re on site. HBC insurance is about what happens if the contractor can’t complete or fix the work because they’ve died, disappeared, or gone insolvent. They cover different risks — both matter, neither replaces the other. Don’t accept one as a substitute for the other.
Don’t pay the deposit. A contractor who can’t or won’t provide the certificate before taking payment is either uninsured or unlicensed — neither is a situation you want to be in. Contact NSW Fair Trading to report it.
