Building a new home or renovating an existing house is a substantial undertaking as it requires a significant outlay of money and planning. Throughout Australia, building regulations governing registered builders are in place to provide basic transparency to the public about a builder’s license status, any infringements or conditions and basic registration details. It is no guarantee about the Builder’s performance on a home builder’s project but an indication as to their compliance with the minimum requirements to be a “Registered Builder” in Australia. 

Before you agree to any building agreement, it is imperative to verify a builder or contractor license. Not doing so could mean you are exposed to a dodgy builder’s practices. 

According to Builder Insights, referring to analysis published in the Australian Financial Review about construction company failures, “The construction sector recorded more than 2,000 company insolvencies in a recent financial year 2024″ and whilst a Builder’s licensing compliance is no guarantee of financial strength, a Builder with an impaired License is likely to have had or have financial challenges that may become your building nightmare without basis due diligence.  

This shows the real level of risk homeowners can face if proper checks are not done.

Why Licensing Is Important in Australia

Building regulation is the responsibility of a specific licensing body in every state and territory of Australia. These bodies decide what training, safety levels and qualifications are necessary. To be a licensed builder, a person needs to prove they have met the minimum requirements.  

A license legally obliges as a condition of registration to comply and abide by building regulations in the relevant state of territory. 

When you Verify a builder license, it provides a level of confidence that the Builder has met minimum licensing requirements in their state or territory but it does not verify their financial acumen, business ethics or character or current credit rating. It is, of itself insufficient for a home builder to rely upon exclusively before they sign a contract with a builder. 

Where to Check Builder Licences

Licence checks are simple and free. Each state provides online licence search tools.

You only need the builder’s trading name or licence number. Always match the licence details with the contract details provided by the builder to ensure you are dealing with the same individual.

Check Licence Class and Work Type

Licences are not all identical. Certain ones deal with routine construction, while others deal with more skilled jobs, like roofing, pipework or alterations to a building’s frame, for example.

You should be certain the licence suits the work being done. A builder permitted to do minor improvements may not require a builder license provided the contract value is under $3,300 or similar. Other license types permit building of single, double or multi level building so ensure you are aware of the type of license your chosen builder is required to have for your proposed project before you engage in a contract. 

Confirm Building Warranty Insurance status 

Licensed builders must provide mandatory insurance for residential building projects. This includes home building compensation insurance in many states.

State / Territory	Mandatory Warranty Insurance?	Scheme Name	Contract Value Threshold (Approx.)	Key Requirement
New South Wales (NSW)	✅ Yes	Home Building Compensation (HBC)	> $20,000	Builder must obtain insurance and provide certificate before starting work or taking deposit
Victoria (VIC)	✅ Yes	Domestic Building Insurance (DBI)	> $16,000	Insurance certificate required before deposit or work commences
Queensland (QLD)	✅ Yes	Queensland Home Warranty Scheme	> $3,300	Mandatory insurance lodged with QBCC before work starts
Western Australia (WA)	✅ Yes	Home Indemnity Insurance	> $20,000	Builder must take out insurance before receiving payment
South Australia (SA)	✅ Yes	Building Indemnity Insurance	> $12,000	Required before building approval or contract execution
Australian Capital Territory (ACT)	✅ Yes	Builders Warranty Insurance	> $12,000	Must be in place before work begins
Northern Territory (NT)	❌ No (Not mandatory)	N/A	N/A	No compulsory statutory home warranty insurance scheme
Tasmania (TAS)	❌ No (Not mandatory)	N/A	N/A	No mandatory home warranty insurance scheme

This insurance protects you if the builder becomes insolvent, disappears or passes away before completing the work.

Ask for the insurance certificate before paying any deposit. Check that your project details are listed correctly.

Review Compliance History

A licence alone is not enough. You should also check compliance history.

Look for past licence suspensions, major complaints or legal disputes. Many regulators publish disciplinary actions online. You can also check company financial history through ASIC records.

This gives you a complete picture of the contractor reliability and professionalism.

Understand Your Contract Obligations

A building contract that is legally sound should contain details of any necessary licences, the work to be done, the schedule for the work and how payment will be made. Do not sign agreements that are not complete or are unclear. 

If any of the conditions in the contract are not understood, you should obtain legal counsel. A relatively small cost for a review of the contract can avoid large disagreements at a later point.

Watch for Warning Signs

Be cautious if a Builder:

• Refuses to provide licence details
• Pushes for large upfront payments
• Offers unusually cheap quotes
• Avoids written agreements

These signs may indicate legal or financial risk. Always take time to check properly.

Protecting Your Home and Legal Rights

Your home is often your biggest asset. Protecting it starts before construction begins.

Always verify a builder or contractor license and confirm legal compliance. Check licence validity. Confirm insurances including warranty insurance in in place. Review their building authority compliance history. Read contracts carefully and get a professional opinion at a minimum as some contracts run to 50 or more pages. 

According to Builder Insights, citing data reported through ASIC and Australian construction sector reporting, “The construction industry continues to record one of the highest insolvency rates across Australian industries, reinforcing why homeowners must confirm licensing and financial compliance before engaging a builder.” This reinforces the importance of careful checks.

Taking these steps reduces financial risk and legal stress. Most Australian contractors operate professionally. But strong verification protects you from rare but costly mistakes.

Making informed decisions today can protect your home, finances and peace of mind long into the future.
