Home Warranty Insurance for Renovations Victoria

Your kitchen renovation quote came in at $18,500. You figured that meant Home Warranty insurance wasn't required, one less thing to check. Then the builder pulled up the old flooring and found rot in the subfloor. A variation went on the contract. The total is now $23,000.

Does your cover apply? And would you know if it didn't?

Quick answer:

A renovation needs Home Warranty insurance if the contract is worth more than $20,000, covers a building up to three storeys, and was signed on or after 1 July 2026.
That threshold is measured against the contract value, including variations, not your original quote.
If a change order pushes you over $20,000 partway through, your builder has 10 business days from the date that variation is signed to pay the insurance premium.

This guide walks through how the threshold is calculated, the variation trap most renovators don't see coming, what the cover actually pays out, and how to check it's in place before your next progress payment.

Does my renovation need Home Warranty cover?

Home Warranty is Victoria's mandatory builder insurance scheme, administered by the Building and Plumbing Commission (BPC). It replaced the old Domestic Building Insurance (DBI) scheme for contracts signed on or after 1 July 2026. You may also see it referred to as the "First Resort Home Warranty Scheme," same scheme, different name.

Three things determine whether your renovation needs it:

Contract value: more than $20,000
Building scope: a building up to three storeys
Contract date: signed on or after 1 July 2026

If your contract was signed before 1 July 2026, the old DBI rules apply instead, with a lower $16,000 threshold and a $300,000 cap. Those older contracts stay under DBI's terms for the life of the project, they don't upgrade automatically. See DBI vs Home Warranty: does the date you signed decide your cover? if you're not sure which scheme applies to you.

A small bathroom refresh or a single-trade job might genuinely sit under $20,000 and stay there. Plenty of renovations don't, especially anything involving structural work, an extension, or a full kitchen strip-out.

How the $20,000 threshold is actually calculated

The threshold is based on the contract price, not the number scribbled on an early quote. If you negotiated down from an initial estimate, or the final signed figure differs from what you first discussed, it's the signed contract value that counts.

This matters because renovation quoting is rarely a single fixed number from the first conversation. Homeowners often collect two to four quotes, negotiate scope, and sign a contract for a figure that's moved since the first estimate. Check the number on the document you actually sign, not the one in the original email.

The variation trap: what happens if a change order pushes you over $20,000

This is the part most renovators don't know about, and it's genuinely easy to miss.

Say your renovation starts at $17,000, comfortably under the threshold. Midway through, the builder finds something the original scope didn't cover: rot behind a wall, an unexpected wiring issue, a client-requested upgrade to fittings. A variation goes on the contract, and the total climbs to $22,000.

That variation just changed your project's legal status. Once a signed variation takes a contract to $20,000 or more, the builder is required to pay the Home Warranty premium within 10 business days of that variation being signed, the same 10-business-day clock that applies at initial contract signing. If your renovation was small enough to fly under the radar at the start, it may not stay that way, and the obligation to arrange cover resets the moment the variation is signed.

The practical takeaway: don't assume "my renovation is too small for insurance" is a fact that holds for the whole project. Check it again every time a variation is signed, particularly on jobs that started close to the $20,000 line.

What Home Warranty covers for a renovation

There's no scaled-down, "renovation-size" version of Home Warranty. The caps are the same whether your project is worth $21,000 or $700,000. For an eligible renovation, cover includes:

Deposit refund: up to 5% of the contract price, if work hasn't started
Incomplete work: up to 30% of the contract price, if the builder can't or won't finish
Defective or non-compliant work: major defects within 6 years, other defects within 2 years
Accommodation, removal and storage costs: up to $12,000, where these arise from the above
Overall cap: $400,000 per home
Deductible: $500 to $1,000 per claim, depending on the defect

Home Warranty is also a genuine change from the old DBI model. DBI only paid out if the builder died, disappeared, or went insolvent. Home Warranty responds where work is incomplete, defective, or non-compliant and the builder is unable or unwilling to fix it, which can apply even while the builder is still trading. There's still a process involved (a complaint notice, a response window for the builder, potential escalation), so it isn't an instant payout, but it's a materially different starting point than the old last-resort model.

How to check cover is in place mid-project

A certificate shown to you before you signed doesn't confirm cover exists right now, particularly after a variation. The BPC's Search insurance for your property tool lets you check whether current Home Warranty cover is recorded against your address, independent of anything your builder tells you. The Certificate of Insurance also carries a QR code you can scan to verify it against the BPC's own record.

Run this check at three points:

Before you sign, to confirm cover will apply from day one.
After any variation that might push your contract over $20,000.
Before a major progress payment, so you're not relying on a document shown to you weeks or months earlier.

Independent verification matters because a shown certificate isn't proof it's genuine or current. The BPC's disciplinary register has recorded real cases of builders using fraudulent insurance certificates, in at least one case a builder was fined and disqualified for it, which is exactly the scenario an independent check catches.

Insurance is one half of the picture. It's also worth confirming the builder themselves is currently registered to do the work at all, which you can do through a VIC builder registration check alongside your insurance check. And if the variation itself has you wondering whether the builder can actually deliver, or whether you have options if they won't, what happens if your builder won't fix defective work covers the claim process in full.

If you're still comparing two or three quotes and want a fuller background picture before you sign with any of them, not just registration and insurance status but the builder's wider record, you can compare builders with a TrustSignal check before you commit.

FAQ

Is my renovation exempt from Home Warranty if it's under $20,000?
Yes, if the signed contract value stays under $20,000 and the building is up to three storeys, Home Warranty isn't mandatory. It's worth rechecking this after any variation, since a change order can push a small job over the line partway through.

My quote was under $20,000 but the final contract came to more. Am I covered?
The threshold is based on the signed contract value, including variations, not the original quote. If a variation takes your total to $20,000 or more, your builder is required to pay the Home Warranty premium within 10 business days of that variation being signed.

Does Home Warranty apply to a two-storey extension?
Yes. Home Warranty applies to domestic building work, renovations and extensions included, on buildings up to three storeys, which covers most house extensions and renovations. It doesn't apply to residential buildings of more than three storeys with more than two homes.

What if my renovation contract was signed before 1 July 2026?
It stays under the old DBI scheme for the life of the project: a $16,000 threshold, a $300,000 cap, and cover that only responds if the builder died, became insolvent, or disappeared. Home Warranty's improved terms don't apply retrospectively.

How much is the deductible if I need to make a claim?
Between $500 and $1,000 per claim, depending on the age of the defect, on top of the other caps that apply to your claim type.
