NSW Builder Licence Check: What to Check Before You Sign - Verify NSW

If you are planning a new build, renovation, duplex, knockdown rebuild or major residential project in New South Wales, the first practical step is a NSW builder licence check. The public pathway for checking a builder licence in NSW runs through Service NSW and Verify NSW, with Building Commission NSW responsible for building licensing and regulation. The register is free to search and takes a few minutes before you sign anything.

Here is the direct answer: you can check whether a builder is licensed in NSW through Service NSW. This tells you whether the builder is currently authorised to do the type of work you are planning.

In NSW, builders and tradespeople generally need a contractor licence for residential building work where the total cost of labour and materials is more than $5,000.

It is the right first step. It is not the last one.

A licence check through Service NSW can help you confirm whether a builder is licensed. But before you sign, you should also check whether the builder, company and directors show wider risk signals, such as insurance status, company strength, director history, insolvency indicators, court or tribunal matters, and credit-risk signals.

Before you sign or pay a deposit, make sure the licence, the contract name, the company details and the insurance all match.

What is NSW Fair Trading, and who actually licenses builders now?

Most NSW homeowners search for "NSW Fair Trading builder licence check," and that search habit is not wrong, it is just slightly out of date.

NSW Fair Trading is the regulator most homeowners still associate with builder licensing in NSW, and it remains a real consumer-facing brand. But building licensing functions now sit with Building Commission NSW, the specialist regulator responsible for issuing, monitoring and disciplining contractor licences under the Home Building Act 1989. Service NSW is the transaction layer, the website you actually use to run the search, and Verify NSW is the public register behind it.

In practice, this means:

Service NSW is where you go to start the search
Verify NSW is the register that holds the actual licence data
Building Commission NSW is the regulator responsible for licensing, compliance and disciplinary action
NSW Fair Trading is the legacy name, still useful for finding the right tool, but no longer the body that issues or polices building licences

You do not need to know this distinction to run the check. You do need to know it so you are not confused when search results, contracts or older guidance reference NSW Fair Trading instead of Building Commission NSW.

How to check a NSW builder licence

The official NSW licence check is available through Service NSW's "Check a builder or tradesperson licence" tool and the Verify NSW register for contractor and tradesperson records. Here is how to use it:

Go to the licence check tool. Search by licence number, licensee name, ABN, ACN, licence type or location. In practice, you will also want to check the builder's legal name, company name or trading name against the result.
Check the licence holder details. Confirm the name shown on the register, whether that is an individual or a company.
Confirm the licence status. Look for a Current status. Treat expired, suspended or cancelled records as a reason to stop and ask questions before going further.
Confirm the licence category or class. For a new home, this is typically "General Building Work" or "Residential Building Work". A category limited to a specific trade, such as carpentry or tiling, does not cover managing a full build.
Check for conditions or restrictions. Some licences carry conditions that limit the scope of work the holder can take on.
Check the expiry date. A licence close to expiry is worth a quick follow-up question about renewal.
Check whether the name matches who you are contracting with. The name on the licence should line up with the name on your quote and contract, where shown.

Register results can vary in detail depending on the licence type and what information is published. Where the result shows less than you expect, treat that as a prompt to ask the builder directly, rather than to assume the information does not exist.

What to confirm on the NSW builder licence record

When you run a builders licence check in NSW, work through this list:

Licence number: the unique identifier for the licence
Licence holder name: the individual or company the licence is issued to
Company name, if applicable: the registered legal entity behind the licence
Trading name, if applicable: the name the business uses day to day, which may differ from the company name
Licence class or category: what type of building work the licence covers
Current status: Current, expired, suspended or cancelled
Expiry date: when the licence needs to be renewed
Conditions or restrictions: any limits on what the licence holder can do
Nominated supervisor or qualified supervisor, where relevant: the individual responsible for supervising licensed work on behalf of a company. For company licences, check whether the nominated supervisor shown on the licence is still connected to the business. A company licence may depend on an appropriately licensed nominated supervisor
Disciplinary information, where available: any public warnings or regulatory action shown on the register
Whether the licence matches the work you need done: a general building licence for a renovation that is mostly structural is different to a licence limited to a single trade

Not every field will be visible for every licence. Where information is not shown, that does not necessarily mean there is nothing to know, it may simply mean the register does not publish that detail for that licence type.

NSW builder licence classes explained

Not every licence on Verify NSW is the same, and the class shown on the record determines what the holder is actually allowed to do.

Contractor licence (building): the licence that lets an individual or company contract and advertise for residential building work. This is the licence you want to see if you are signing a contract with a builder to manage your project.
Qualified Supervisor Certificate: authorises the holder to supervise and carry out licensed work, but does not authorise them to contract with you directly. A builder operating on a supervisor certificate alone cannot legally take your contract, even if they are doing the work on site.
Tradesperson certificate: issued to individuals for specific trade work, carried out under the general supervision of a contractor licence or qualified supervisor certificate holder. A tradesperson certificate holder cannot sign off their own work as the contracting party.
Owner-builder permit: for homeowners managing or carrying out building work on their own land, rather than engaging a licensed contractor. If you see an owner-builder permit on a search result for a business presenting itself as a commercial builder, that is a mismatch worth asking about.
Specialist trade licences (electrical, plumbing, draining and gasfitting, air conditioning, swimming pool building): these sit on the same Verify NSW Trades register as building contractor licences, searchable the same way.
Demolition and asbestos removal: these do not sit on the building licence register at all. Demolition was removed from the Home Building Act licensing scheme in 2008, and both demolition and asbestos removal licences are issued by SafeWork NSW, searchable on a separate "Asbestos and demolition licence holder" register at verify.licence.nsw.gov.au/home/ADL. If your project involves either, check there, not the Trades register.

For a new build or full renovation, the licence you want to see is a current Contractor Licence in the Building class. Anything else on its own is a reason to ask a follow-up question before you sign.

Why the name on the licence must match your contract

This is one of the most overlooked steps in a NSW builder licence check, and one of the most important.

A licence is held by a specific legal entity, either an individual or a company with its own ABN and, if it is a company, an ACN. The business you deal with day to day might operate under a trading name that looks nothing like the name on the licence.

Here is what to check:

The trading name may be different from the legal company name. "Sydney Premium Builds" might be a trading name for a company registered under a completely different name.
The ABN and ACN on your contract matter. These identify the legal entity you are actually contracting with, separate from any trading name or marketing brand.
The licence may sit with an individual, a company, or a related entity. A licence held by a director personally is not the same as a licence held by the company that will be named on your contract.
Check that the party taking your deposit and signing the contract is the party you have checked. If the licence is in one name and the contract is with another, that is worth resolving before you pay anything.
If the licence, ABN, company name and contract name do not line up, ask questions before signing. There may be a simple explanation, such as a recent restructure or an updated trading name, but it is worth getting that explanation in writing.
The HBCF insurance certificate, where one is required, should name the same entity. A certificate in a different company name is worth querying before you pay a deposit.

Home Building Compensation Fund (HBCF) insurance

A NSW licence check and HBCF insurance are checked through two completely separate systems, and this is one of the most common points of confusion.

For residential building work over $20,000 (including GST), the builder generally must have Home Building Compensation cover, still widely known as HBCF, in place before they can accept a deposit or start work. The cover protects you, the homeowner, if the builder cannot finish the job or fix defects because of one of four trigger events: insolvency, death, disappearance, or licence suspension for non-compliance with a tribunal or court money order.

The maximum claim is $340,000 per property (for policies issued from 1 February 2012; $300,000 for older policies), and it is the total available, including any claims by a previous owner of the same property. Claim time limits are 6 years from completion for major defects, 2 years for other defects, and 12 months from cessation of work for incomplete work.

The critical point: a standard licence search does not show whether HBCF cover exists for your specific project. That is checked separately through the HBC Check tool on Verify NSW, searchable by certificate number, the builder's name or licence number, or the property address. Before a contract exists, this tool can show you a builder's HBCF eligibility and certificate history. The certificate for your specific job will not exist, and cannot be checked, until you actually have a signed contract.

See How to Verify a Builder's HBCF Insurance in NSW for the full two-phase process, before and after signing.

Statutory warranties: your rights under a NSW building contract

Separate from HBCF insurance, NSW building contracts carry statutory warranties under the Home Building Act 1989. These are legal rights you hold directly against the builder, not an insurance claim against a fund.

Under these warranties, the builder promises that the work will be:

Carried out with due care and skill
Built using materials that are new and suitable for the purpose, unless you agreed otherwise
Completed in accordance with the plans, specifications and any applicable law
Fit for occupation, where the work is intended to make the home liveable

These warranties run for set periods: 6 years from completion for a major defect, and 2 years from completion for anything else. A "major defect" is generally one that means you cannot reasonably use the building for its intended purpose, or one that affects a major structural element, fire safety, or causes a risk to health and safety.

A licence check does not show you whether a specific builder has a history of breaching these warranties, that requires a search of NCAT and court records, covered in the Complete Verification Guide. But knowing the warranty exists, and how long it lasts, matters before you sign, since it is one of the protections you are relying on if something goes wrong after handover.

Deposit and progress payment limits in NSW

The Home Building Act 1989 caps the maximum deposit a NSW builder can request at 10% of the contract price. A request for more than that is a reason to ask a direct question before you sign or pay anything.

For contracts over $20,000, additional protections apply: the contract must include a set of prescribed items, the price must be stated upfront with any variation terms explained, and you generally have a short cooling-off period after signing. Progress payments beyond the deposit should be tied to defined, completed stages of work, not requested ahead of the work being done.

None of this is shown on a licence search. It is a contract-level protection, worth checking against your own paperwork once you have a quote or draft contract in hand.

What a NSW builder licence check covers, and what it leaves unchecked

A standard NSW licence check covers:

Licence status (Current, Suspended, Cancelled or Expired)
Licence class (for example, General Building Work vs. a restricted trade licence such as carpentry or tiling)
Nominated supervisor details, where shown
Conditions and restrictions on the licence
Official cautions and regulatory sanctions, where published on the register

Some regulatory outcomes, such as a compliance failure on a money order, may result in a suspension visible on the register. However, a licence search is not a complete search of NCAT, court or insolvency history. Those sit in separate systems.

What a licence check leaves completely unchecked:

Financial stability and liquidity
Insolvency and bankruptcy indicators
Director history, including links to failed or phoenix companies
NCAT disputes and ongoing court matters
Payment disputes, credit-risk signals and PPSR indicators
Project-specific home building compensation (HBC) insurance approval

A current licence and a sound business are two different things. The licence check answers "is this builder licensed to contract for the relevant residential building work in NSW", not "can this builder see my project through, and is there anything in their background worth knowing first".

A licence check is only one part of builder due diligence. TrustSignal helps you check the broader risk picture before you sign.

For a state-by-state look at how licence checks work across Australia, see our guide to How to Check a Builder Licence in Australia Before You Sign. Building in Queensland, Victoria or Western Australia instead? See our equivalent guides for QLD, VIC and WA. If you want to work through every one of these areas in detail, How to Check a Builder in NSW: The Complete Verification Guide covers the eight questions that come after the licence check: business history, insurance, regulatory sanctions, disputes, insolvency and payment behaviour.

If your licence verification fails

A search result that is not straightforwardly "Current and clean" is not automatically a reason to walk away, but it is always a reason to stop and ask a question before you go further.

Status shows expired, suspended or cancelled. Do not sign or pay anything until this is resolved. Ask the builder directly for an explanation, and verify any explanation against the register again afterwards.
You cannot find the licence at all. Double-check the spelling of the name, try searching by ABN instead, and check whether you have the legal name rather than a trading name. If it still cannot be found, ask the builder for their exact licence number in writing.
The name on the result does not match your quote or contract. Treat this as something to clarify, not ignore, per the entity-matching section above.
The licence category does not cover your project. Ask whether the builder intends to use a different, appropriately licensed entity or subcontractor for the parts of the work outside their licence class.
You are still unsure. Contact Building Commission NSW directly, or use TrustSignal to check the wider record before you commit.

None of these situations automatically means the builder is acting in bad faith. They do mean the next step is a direct question and a written answer, not a signature.

NSW vs other states

Licensing in Australia is run state by state, and the terms, registers and insurance schemes differ. NSW uses "contractor licence" and HBCF; Victoria uses "registration" and Domestic Building Insurance; Queensland uses a QBCC licence and the Queensland Home Warranty Scheme; Western Australia uses "registration" and Home Indemnity Insurance, and does not publish trading names on its register at all.

If you are building outside NSW, use the state-specific guide rather than applying NSW figures to a different state: VIC Builder Licence Check, QLD Builder Licence Check, WA Builder Licence Check, or the Australia-wide state-by-state guide for every state and territory in one place.

Beyond the licence: what else to check before you sign

A licence check is the starting point. Here is a short summary of the other checks worth doing before you sign or pay a deposit, each covered in more detail elsewhere:

Company, ABN and directors. Confirm the ABN, and ACN if it is a company, check the company's status with ASIC, and look at who the directors are and what other entities they are linked to. See How to Check a Builder's Financial Background in NSW.
Court, NCAT and insolvency signals. A licence check does not show NCAT disputes, court matters or insolvency history. Court and tribunal records do not automatically mean a builder is unsafe, but a pattern of disputes or creditor action is worth knowing about before you sign. These checks are covered step by step in the complete verification guide.
Credit-risk and PPSR signals. Indicators of how a business manages its financial obligations and any registered security interests over its assets, also covered in the complete verification guide.

Red flags before signing with a NSW builder

None of the following automatically means a builder is a poor choice. Each one is a prompt to ask a question and get a clear answer before you sign or pay a deposit:

The licence name does not match the contract entity
The licence category does not appear to match the work you need done
The licence has conditions or restrictions that have not been explained
The builder cannot provide an HBCF certificate when one is required
The company name, trading name and ABN are unclear or inconsistent across documents
Recent changes to the company, or a recently registered entity with little trading history
Directors with links to previous building companies that failed
Unresolved disputes or court activity involving the builder or related entities
Pressure to sign or pay quickly, with limited time to check the details
Refusal or reluctance to provide clear licence, insurance or company documentation

How TrustSignal helps

Checking a licence, insurance status, company details, directors, court records, NCAT history, insolvency indicators and credit-risk signals separately means searching multiple government systems that are not linked to each other.

TrustSignal's Builder Report brings licence, insurance, company, director, court, tribunal, insolvency and credit-risk signals together in plain English so NSW homeowners can make a more informed decision before signing.

You can see what this looks like in our sample report, check pricing, or go straight to trustsignal.com.au/search to check a builder.

For a structured checklist that walks through every step before signing, see The NSW Pre-Contract Builder Checklist. For an overview of where these records sit and how to read them, see TrustSignal Public Registers.

NSW builder licence check FAQs

How do I check a NSW builder licence?

Use the Service NSW "Check a builder or tradesperson licence" tool, which searches the Building Commission NSW licence register. Search by licence number, builder name, company name or trading name, then confirm the licence status, category and any conditions.

Where do I do a builders licence check NSW?

The official NSW builders licence check is available through Service NSW and the Verify NSW register, with Building Commission NSW responsible for building licensing and regulation.

Is NSW Fair Trading the official builder licence check?

NSW Fair Trading has historically been the regulator most homeowners associate with builder licensing in NSW. Building licensing functions now sit with Building Commission NSW, accessed through Service NSW. Searching for "fair trading builder licence" will generally lead you to the correct, current licence check tool.

What is the difference between a contractor licence and a qualified supervisor certificate?

A contractor licence lets the holder contract and advertise for residential building work in their own right. A qualified supervisor certificate authorises the holder to supervise or carry out licensed work, but not to contract with you directly. If the only credential a builder can show you is a supervisor certificate, they cannot legally be the contracting party on your build.

Is a current NSW builder licence enough?

A current licence is the right first step. It confirms the builder appears licensed to contract for the relevant residential building work. It does not confirm financial stability, insurance status, dispute history, director history, or court and tribunal matters. A NSW builder licence check is necessary, but it is not the full picture before you sign.

What if the builder licence name is different from the contract name?

Treat this as something to clarify, not ignore. Ask for the registered company name and ABN behind the licence, and confirm it matches the entity named in your contract. If there is a mismatch with no clear explanation, get this resolved in writing before paying a deposit.

Should I check HBCF insurance as well?

Yes, and separately from the licence. In NSW, home building compensation insurance (often still called HBCF cover) is generally required for residential building work over $20,000 including GST unless an exemption applies. A current licence does not automatically prove that HBC cover has been issued for your specific project, that is checked through a different tool. See how to verify a builder's HBCF insurance in NSW for the steps.

What is a statutory warranty, and is it the same as HBCF insurance?

No. A statutory warranty is a legal right you hold directly against the builder under the Home Building Act, covering due care and skill, suitable materials, and compliance with plans, for 6 years on major defects and 2 years on other defects. HBCF is a separate insurance fund you can claim against only if the builder becomes insolvent, dies, disappears, or has their licence suspended for non-compliance with a money order. They work together, but they are not the same protection.

What is the maximum deposit a NSW builder can ask for?

10% of the contract price, under the Home Building Act 1989. A request for a larger deposit is worth a direct question before you agree to it.

What should I do if the licence search comes back suspended or cancelled?

Stop. Do not sign or pay anything until you have a clear, written explanation from the builder, and verify that explanation against the register again before proceeding.

Can a licensed builder still have financial problems?

Yes. Licensing status and financial position are assessed separately and can change at different times. A builder can hold a current licence while the company behind it shows insolvency indicators, director links to failed companies, or other credit-risk signals. These do not appear on the licence register.

How do I check a builder in NSW before signing?

Start with a NSW builder licence check through Service NSW. Then confirm the contract entity, ABN, ACN and HBCF insurance all match, check company status with ASIC, and consider a broader check of director, court, tribunal, insolvency and credit-risk signals before you sign or pay a deposit.

What is the difference between a licence check and a full builder check in NSW?

A licence check confirms whether a builder is currently licensed to contract for the relevant residential building work in NSW. A full builder check goes further, looking at insurance, company and ABN details, directors, court and NCAT history, insolvency indicators and credit-risk signals. For the full eight-question process beyond the licence, see How to Check a Builder in NSW: The Complete Verification Guide.

What does a TrustSignal Builder Report check?

The TrustSignal Builder Report brings together licence status, insurance indicators, company and ABN details, director information, court and NCAT records, insolvency indicators and credit-risk signals in one plain-English report. See a sample report or pricing.
