Builders warranty insurance NSW requirements should be checked before taking a deposit or starting eligible residential building work. Confirm the project, value and any exemption, and keep the Home Building Compensation question separate from other insurance obligations. See ABS’s builders warranty insurance service.
This guide explains builders warranty insurance, project evidence and common compliance questions. It also points to current NSW guidance on the separate building practitioner insurance requirements.
What Is Builders Warranty Insurance in NSW?
Builders Warranty Insurance (BWI) — also called Home Building Compensation (HBC) cover in NSW — is a statutory insurance product that protects homeowners if their licensed builder dies, disappears, becomes insolvent, or has their licence suspended before completing the work or honouring a warranty claim.
It's not cover for the builder. It's cover for the homeowner, but the builder must arrange and pay for it before work begins.
In NSW, the scheme is administered under the Home Building Act 1989 and overseen by the State Insurance Regulatory Authority (SIRA). The fund is now underwritten by icare (Insurance and Care NSW), which took over the scheme from private insurers.
What Does It Cover?
BWI in NSW covers homeowners for:
- Incomplete work — if the builder cannot complete the contract due to insolvency, death, or licence suspension
- Defective work — structural defects for six years, non-structural defects for two years
- Failure to pay compensation — if the builder is ordered to pay compensation but cannot
The cover kicks in only when the builder is unable to remedy the problem themselves — it's a "last resort" policy, not a first-call claims product.
When Is BWI Mandatory in NSW?
You must obtain BWI before:
- Taking a deposit from a homeowner
- Entering into a residential building contract
The mandatory threshold in NSW is residential building work valued at more than $20,000 (including labour and materials). Contracts below this threshold are exempt.
Work types that require BWI include:
- New residential construction
- Residential alterations and additions
- Swimming pools (when connected to a dwelling)
- Certain specialist work categories
Work types that are generally exempt include:
- Commercial construction
- Owner-builder work (different rules apply)
- Work on buildings with more than three storeys
- Strata building work in some circumstances (check current SIRA guidance)
If you're unsure whether your contract triggers the requirement, speaking with a specialist broker before you sign is the fastest way to get a clear answer.
How Much Cover Is Required?
The minimum level of BWI cover in NSW is $340,000 per dwelling. This figure is set by SIRA and has been subject to periodic review, so confirm the current minimum applies to your contract at the time of arranging cover.
For larger residential projects — particularly multi-dwelling developments — the cover requirement applies per dwelling, not per contract. A project with four townhouses, for example, requires cover for each individual dwelling.
DBP Insurance: Current Building Practitioner Exemption
As checked on 25 October 2026, NSW has extended the registered building practitioner insurance exemption to 30 June 2027. The earlier 1 July 2026 commencement date is no longer current. See the Building Commission NSW update.
Check the Requirements for Your Registration
The relevant framework is the Design and Building Practitioners Act 2020 and its 2021 Regulation. Check your registration role, the work performed and current requirements before relying on an exemption.
Review the Policy Against Your Work
Provide your broker with your registrations, contracts and scope of services. Ask for a written explanation of the relevant insured activities, exclusions, limits and notification conditions.
Keep HBC and Professional Indemnity Separate
Home Building Compensation and professional indemnity are separate insurance questions. Review both against your work and registration with ABS’s home warranty and professional indemnity teams.
Common Mistakes NSW Builders Make With BWI
1. Starting Work Before the Certificate Is Issued
BWI must be in place before you take a deposit or start work. The certificate of insurance must be provided to the homeowner before you receive any money. Starting work without it — even if you've applied — is a breach of the Home Building Act.
2. Assuming Your General Construction Insurance Covers It
It doesn't. BWI is a separate, statutory product. Your contract works policy, public liability cover, and tools insurance are all important, but none of them satisfy the BWI obligation.
3. Getting the Wrong Policy Type
Not every insurer offers icare-backed HBC cover in NSW. The product is specific, and the certificate format matters. A broker who understands the NSW scheme will ensure you receive the correct documentation.
4. Forgetting to Renew When Projects Extend
If your project runs over the original contract period, your BWI certificate needs to remain current. Lapses in cover during active projects create real exposure.
5. Misunderstanding the DBP Act Obligations
Check the current requirements for your registration and work. The registered building practitioner insurance exemption has been extended to 30 June 2027; contractual and other insurance obligations still need separate review.
How to Obtain BWI in NSW
The process for obtaining BWI in NSW runs through icare, but access to the scheme is typically arranged through a licensed insurance broker or agent. The key steps are:
Confirm your eligibility — icare assesses builders based on financial standing, licence status, and project history. Not all builders are automatically eligible for unlimited cover.
Determine your project value — the premium is calculated based on the contract value.
Apply before signing the contract — you need the certificate before you can legally take a deposit.
Provide the certificate to the homeowner — this is a legal requirement under the Home Building Act.
Retain records — keep copies of all BWI certificates for your project files.
For builders with complex project histories, high annual volumes, or eligibility questions, working through a specialist broker adds real value. A broker who understands the icare scheme can help you navigate eligibility assessments and ensure your documentation is correct.
Why a Specialist Broker Matters for NSW Builders
Online comparison platforms can generate quotes quickly, but BWI in NSW is not a product you can simply select from a dropdown menu. The icare scheme has eligibility criteria, documentation requirements, and compliance obligations that require genuine expertise to navigate correctly.
A specialist construction insurance broker brings several advantages:
- Eligibility guidance — understanding whether your financial position and project history will be assessed favourably, and how to present your application
- Correct documentation — ensuring the certificate format meets SIRA and Home Building Act requirements
- Bundled cover — arranging BWI alongside your contract works, public liability, and DBP Act PI cover in a single, coordinated program
- Claims support — if a dispute arises, having a broker in your corner who understands the construction insurance market is meaningfully different from being self-insured through a digital platform

BWI Requirements in Other States: A Quick Comparison
If you work across state borders, it's worth knowing that mandatory home warranty insurance schemes operate differently in each jurisdiction.
| State | Scheme Name | Administering Body | Mandatory Threshold |
|---|---|---|---|
| NSW | Home Building Compensation (HBC) | icare / SIRA | Contracts >$20,000 |
| VIC | Domestic Building Insurance (DBI) | VMIA | Contracts >$16,000 |
| WA | Home Indemnity Insurance | Private insurers | Contracts >$20,000 |
| SA | Building Indemnity Insurance | Private insurers | Contracts >$12,000 |
| ACT | Home Warranty Insurance | Private insurers | Contracts >$12,000 |
| QLD | Queensland Home Warranty Scheme | QBCC | Contracts >$3,300 |
Each state has its own eligibility rules, minimum cover amounts, and approved insurers. If you hold a licence in multiple states, your insurance program needs to reflect each jurisdiction's requirements.
Getting Compliant in 2026: A Practical Checklist
If you're a licensed NSW builder reviewing your insurance obligations right now, work through this list:
- Confirm all active residential contracts above $20,000 have valid BWI certificates
- Check that BWI certificates have been provided to homeowners before any deposit was received
- Check current NSW insurance requirements for your registration and work, including the building practitioner exemption, and review contractual obligations with your broker.
- Ensure your PI policy has the correct retroactive date and run-off provisions
- Check that your contract works and public liability policies are current and adequate for your project pipeline
- Speak with a specialist broker if you have any eligibility questions or are unsure whether your current policies meet the 2026 requirements
If you're not certain about any item on this list, the safest step is to speak with a broker who specialises in construction insurance rather than relying on a general business insurance platform.

Frequently Asked Questions
What is Builders Warranty Insurance in NSW?
Builders Warranty Insurance (also called Home Building Compensation cover) is a mandatory statutory insurance product in NSW. It protects homeowners if their licensed builder dies, becomes insolvent, or has their licence suspended before completing the work or honouring a defect warranty. Builders must arrange and pay for it before taking a deposit on eligible residential contracts.
When is BWI mandatory in NSW?
BWI is mandatory for residential building contracts valued at more than $20,000 (including labour and materials). The certificate must be obtained before you take any deposit from the homeowner and before work begins. Failing to do so is a breach of the Home Building Act 1989.
What is the minimum cover amount for BWI in NSW?
The minimum cover is $340,000 per dwelling. For multi-dwelling projects, this applies per dwelling, not per contract. Confirm the current minimum with your broker at the time of arranging cover, as SIRA can update the figure by regulation.
What is the current building practitioner insurance exemption?
The earlier date was deferred. NSW extended the registered building practitioner insurance exemption to 30 June 2027. Check current government guidance for your registration role before arranging cover.
Does my public liability or contract works insurance cover the BWI requirement?
No. BWI is a separate statutory product. Your public liability, contract works, and tools insurance are all important parts of a construction insurance program, but none of them satisfy the BWI obligation under the Home Building Act. You need a specific HBC certificate issued through the icare scheme.
Can I arrange BWI through an online comparison platform?
BWI in NSW is not a standard off-the-shelf product available through general comparison platforms. The icare scheme has eligibility criteria and specific documentation requirements. For most builders, working through a specialist construction insurance broker is the practical route to obtaining correct cover and the right certificate format.
How do I get BWI as a licensed NSW builder?
Contact a specialist insurance broker who arranges HBC cover through the icare scheme. The broker will assess your eligibility, calculate the premium based on your contract value, and issue the certificate you need to provide to the homeowner. ABS Insurance Brokers arranges BWI for licensed builders across NSW and can be reached through abshow.com.au.
