How to Check a Builder Licence in Australia Before You Sign

Before you sign a building contract or pay a deposit, check that your builder is licensed.

A builder licence check is the right first step. It helps confirm whether the builder is authorised to perform certain building work in your state or territory. It can also show whether the licence appears current, whether it matches the type of work being quoted, and whether there are restrictions, conditions or disciplinary records available through the relevant public register.

But a licence check is not the full check.

A licence does not prove that a builder is financially stable. It does not tell you whether the company has payment disputes, court matters, tribunal history, insolvency indicators, insurance gaps, director links to failed companies, PPSR registrations or other credit-risk signals.

That is why the safest approach is simple:

Check the builder licence first. Then check the wider record before you sign.

Want to check more than the licence? Run a TrustSignal Builder Report before you sign.

Builder licence check: state-by-state guide

Each state and territory has its own public licence or registration register. The exact information available varies, but the purpose is similar: confirm that the person or business you are dealing with is properly authorised for the work.

A good builder licence check is not just a name search.

Compare the register result against the quote, contract, ABN, ACN, website, invoice and licence number supplied by the builder.

The key question is:

Is the entity you are contracting with the same entity that holds the licence or registration?

That distinction matters.

You can also see TrustSignal’s broader guide to Australian public registers for builder checks.

NSW builder licence check

In NSW, homeowners can check builder and tradesperson licence details through NSW Verify or Service NSW.

Official source: Service NSW — Check a builder or tradesperson licence

Check:

licence number
licence holder name
contractor licence status
licence class or category
expiry date
conditions or restrictions
qualified supervisor details where relevant
whether the licence holder matches your quote and contract

Why it matters:

A NSW builder licence check helps confirm whether the builder or contractor is licensed for the work before you sign a contract or pay money. You should also check whether the name on the licence matches the person or company named in your quote and contract.

Do not stop at the licence number. If your contract is with a company, check the company name and ABN or ACN as well.

For NSW residential building work, also check whether Home Building Compensation Fund insurance applies to your project. You can read TrustSignal’s guide to how to verify a builder’s HBCF insurance in NSW.

Official source: Service NSW — Use the Home Building Compensation Check

VIC builder registration check

In Victoria, homeowners usually check builder registration through the Victorian Building Authority / Building and Plumbing Commission practitioner search.

Official source: Victorian Building Authority — Find a practitioner

Check:

practitioner or company registration
registration number
registration class
registration status
disciplinary history where available
whether the registration matches the type of work

Why it matters:

Victoria often uses “registration” rather than “licence” language for builders. If you are searching for a registered builder or doing a builder registration check, make sure the registration is current and appropriate for your project.

The practical point is the same: confirm the builder is properly authorised before you sign.

QLD builder licence check

In Queensland, homeowners can use the QBCC Licensee Register.

Official source: QBCC Licensee Register

Check:

QBCC licence number
licensee name
licence class
licence status
conditions or restrictions
directions, exclusions or history where available
whether the licence holder matches the contract entity

Why it matters:

The QBCC register helps confirm whether a builder or company is licensed and whether the licence class matches the type of work being quoted.

The QBCC also notes that its public licence search is restricted to information it is required to keep on its public records. It may not disclose other information such as insolvencies, bankruptcies or civil proceedings involving the licensee.

That is a useful reminder: a builder licence check is important, but it is not the whole picture.

WA builder registration check

In Western Australia, homeowners can use the WA Building and Energy online licence search or registered builder search.

Official sources:

Check:

builder registration number
builder name
registration status
registration category or class
whether the builder appears active
whether the registration matches the work

Why it matters:

WA homeowners should confirm the builder is registered and active for the type of work being quoted.

If the builder is not listed, or the register result does not match the contract details, pause before signing and ask for clarification.

SA builder licence check

In South Australia, homeowners can use the Consumer and Business Services occupational public register.

Official sources:

Check:

licence number
individual or business name
licence type
licence status
expiry date
conditions where shown
whether the licence matches the work

Why it matters:

The SA public register helps confirm whether a person or business is licensed to perform building work.

Search the legal or business name, not just the trading name. If the builder gives you a licence number, compare it against the public register.

TAS builder licence check

In Tasmania, homeowners can use the CBOS licensed occupations search.

Official sources:

Check:

builder or building services provider name
licence status
licence category
whether the licence is current
whether the name matches the quote and contract

Why it matters:

Tasmania’s register helps homeowners confirm whether a builder appears as a current licence holder.

If you cannot find the builder, ask for the correct licence details and verify them before signing.

ACT builder licence check

In the ACT, homeowners can use Access Canberra’s public registers.

Official sources:

Check:

construction occupation licence
licence holder name
business or company name
licence class or category
licence status
nominee details where relevant
whether the licence matches the work

Why it matters:

The ACT register helps confirm whether the builder is licensed for the work. You should also check insurance and make sure the licence details match the party named in your contract.

NT builder registration check

In the Northern Territory, homeowners can use the Building Practitioners Board public register.

Official sources:

Check:

registered building practitioner details
registration category
registration status
name match
whether the practitioner or company is appropriate for the work

Why it matters:

The NT public register helps confirm whether a building practitioner is registered. If the builder is not listed or you are unsure whether registration is required for your project, check with the relevant NT regulator before signing.

What a builder licence check tells you

A builder licence check can tell you important things.

It can help confirm:

whether the builder is authorised to perform certain building work
whether the licence or registration appears current
whether the licence category or class matches the work being quoted
whether there are conditions or restrictions on the licence
whether there is disciplinary information available through the relevant state register
whether the person or company name matches the details you have been given
whether a nominee, supervisor or registered practitioner is attached where required

This is why every homeowner should check builder licence details before signing a contract.

A licensed builder is not automatically the right builder for your project, but an unlicensed or mismatched builder is a serious warning sign.

For example, if you are planning a major renovation, duplex, knockdown rebuild or new home, you do not just want to know that someone has a licence. You want to know that the licence is current, relevant and connected to the actual party named in your contract.

What a builder licence check does not tell you

This is the part many homeowners miss.

A builder licence check is useful, but it is limited.

It does not usually tell you:

whether the builder is financially stable
whether the company has insolvency indicators
whether directors have links to failed companies
whether there are current or past court matters
whether there are tribunal disputes
whether there are payment disputes with subcontractors, suppliers or clients
whether required project insurance is in place
whether there are PPSR or credit-risk signals
whether the trading entity is the same as the licence holder
whether the builder has a history of phoenix-like behaviour
whether the builder has recently changed company structures
whether there are related entities that should also be checked

That does not mean a licence check is useless. It means it is only the first layer.

A licence confirms whether a builder is authorised to do certain work. It does not confirm whether the builder is commercially healthy, dispute-free, insured for your project or low risk.

That is why broader checks matter.

For example:

ASIC publishes insolvency and deregistration notices through its published notices website.
The PPSR is the official Australian register of security interests in personal property.
Court and tribunal searches may reveal disputes or debt-related matters that do not appear in a simple licence check.
Insurance checks can confirm whether required project insurance is in place.

Official sources:

Before you sign or pay a deposit, run a wider check.

Before you sign, run a TrustSignal Builder Report to check the wider record in plain English.

Before you sign, check the wider record

The best time to check a builder is before you sign the contract.

Once you have paid a deposit or committed to a builder, your options can become more difficult, more expensive and more stressful.

A proper pre-contract builder check should cover more than the licence.

At a minimum, check the following.

1. Licence or registration

Confirm the builder is licensed or registered for the type of work you need. Check the licence number, expiry date, status, category and any restrictions.

2. Insurance

Check whether the required project insurance applies.

In NSW, for example, homeowners can use the HBC Check to search for Home Building Compensation insurance for residential building work.

Do not assume insurance exists because a builder says they are licensed. Ask for the certificate and verify the details.

3. Company and ABN details

Check the ABN, ACN, legal name, trading name and contract entity.

The name on the quote, contract, invoice, licence and insurance should make sense together. If they do not, ask questions before you sign.

4. Directors and related entities

Look at who controls the company. Directors may have other current or former building companies. Related entities can help you understand the builder’s broader trading history.

5. Court and tribunal history

Court and tribunal records can show disputes, payment claims, debt recovery actions, building disputes and other legal activity.

Not every dispute means a builder is unsafe, but patterns matter.

6. Insolvency history

Check whether the company or related entities have insolvency indicators. Also consider whether directors have links to failed companies.

ASIC’s published notices website allows users to search and browse insolvency and deregistration notices published from 1 July 2012.

Official source: ASIC — Insolvency notices

7. Credit-risk and repayment signals

Payment behaviour can be an early signal of stress. A builder may still hold a current licence while facing commercial pressure.

8. PPSR indicators

The PPSR is the official Australian register of security interests in personal property.

A PPSR registration does not automatically mean something is wrong. But it can help build a fuller picture of security interests connected to a business or its assets.

Official source: PPSR — Personal Property Securities Register

9. Regulatory sanctions

Look for regulator actions, disciplinary history, warnings or restrictions where available.

10. Trading history

Consider how long the entity has been operating, whether it has recently changed name or structure, and whether the contract entity has a meaningful operating history.

TrustSignal’s Builder Report brings these checks together in plain English so homeowners can make a more informed decision before signing.

Common mistakes homeowners make when checking a builder

Most homeowners are not careless. They are busy, under pressure and trying to make a large decision with limited information.

These are the mistakes to avoid.

Mistake 1: Only checking the licence

A licence check is essential, but it does not cover financial stability, disputes, insurance, insolvency or related company history.

Mistake 2: Searching only the trading name

A builder may trade under one name but contract through another company.

Search the trading name, legal company name, ABN, ACN, director names and licence number where possible.

Mistake 3: Not checking the ABN or ACN

The ABN or ACN helps identify the actual legal entity you are dealing with.

This is important because your contract is with an entity, not just a brand name.

Mistake 4: Assuming reviews prove financial health

Reviews can be useful, but they do not prove a builder is solvent, insured or free of payment pressure.

A builder can have positive reviews and still be under financial stress.

Mistake 5: Not checking insurance before paying a deposit

Ask for the relevant insurance certificate before paying money.

Check that the name, address, contract amount and builder details are correct.

Mistake 6: Not checking whether the contract entity matches the licence

This is a big one.

If the licence is held by an individual but the contract is with a company, you need to understand how the licence, nominee, supervisor and company structure fit together.

Mistake 7: Not looking for court, tribunal or insolvency signals

A single dispute may not mean much.

A pattern of disputes, payment claims, liquidations, related entities or legal action may be more important.

The goal is not to find a perfect builder. The goal is to make an informed decision before you commit.

Builder licence check FAQs

How do I check if a builder is licensed in Australia?

Use the official public register for your state or territory. Search by builder name, company name, licence number, registration number, ABN or ACN where available. Then check the status, category, expiry date, restrictions and whether the licence holder matches the entity named in your quote or contract.

How do I check a NSW builder licence?

Use the NSW Verify or Service NSW licence check tools. Search the builder or tradesperson licence details and confirm the licence number, name, status, expiry date, category and any conditions. For a NSW builder licence check, also confirm whether the contract entity matches the licence holder and whether HBCF insurance applies to your project.

Official source: Service NSW — Check a builder or tradesperson licence

Is a builder licence enough?

No. A builder licence is important, but it is not enough on its own.

It tells you whether the builder is authorised for certain work. It does not prove financial stability, insurance coverage, clean dispute history, absence of court matters or low insolvency risk.

What if the builder uses a company name different from the licence name?

Pause and check the details carefully.

Builders may use trading names, company names, personal licences, nominees or related entities. The key issue is whether the entity signing your contract is properly licensed or connected to the required licence structure.

If the details do not line up, ask for written clarification before signing.

What if the licence is current but the builder has had disputes?

A current licence does not mean there have been no disputes.

Look at the nature, number and pattern of disputes. A single issue may not be decisive. Repeated tribunal matters, court actions, payment disputes or insolvency links may deserve closer attention.

Should I check insurance as well as the licence?

Yes. Licence and insurance are different checks.

A builder may be licensed, but you still need to confirm whether the required project insurance is in place.

Before paying a deposit, ask for the relevant certificate and check that the builder, project address, contract amount and policy details match your job.

What should I check before paying a deposit?

Before paying a deposit, check the builder licence, insurance, ABN or ACN, company name, contract entity, directors, related entities, court and tribunal history, insolvency indicators, regulatory sanctions, PPSR indicators and credit-risk signals.

Can TrustSignal check more than the licence?

Yes. TrustSignal’s Builder Report is designed to help homeowners check the wider record before signing.

It brings together licence, company, director, court, tribunal, insolvency, insurance and risk-signal checks in plain English.

Before you sign or pay a deposit, run a TrustSignal Builder Report to check the wider record.

You can also view a sample Builder Report or see TrustSignal pricing.

Final word

A builder licence check is the right first step.

It helps confirm whether the builder is authorised to perform the work and whether the licence appears current.

But it is not the full picture.

Before you sign a building contract or pay a deposit, check the wider record: licence, insurance, company details, directors, related entities, disputes, insolvency indicators, PPSR signals, sanctions and credit-risk information.

Building is a major financial decision. The goal is not to avoid building. The goal is to choose with better information.

Run a TrustSignal Builder Report before you sign.
