How to Check a Builder in NSW: The Complete Verification Guide

Whilst you may never find out everything you need for complete builder due diligence there is more accessible data than you might think. Before you sign a building contract or hand over a deposit, there are nine questions worth asking about your builder. They are the same questions a TrustSignal Builder Report answers, systematically, for every NSW builder we cover.

Some have answers in public registers: free, accessible today. Some require data that public registers do not hold. Understanding which is which tells you both where to look and what you might be missing.

ASIC insolvency data for 2024-25 show NSW construction insolvencies remained at record or near-record highs. Most of those companies were fully licensed on the day they collapsed. A licence check alone is not a background check.

Q1: How long has the builder been in business?

Why does this matter to you?

You are entering a contract worth tens or hundreds of thousands of dollars. A builder's operational history determines how much public record exists to verify. A very new entity has no track record to assess. A new entity with a familiar director may be continuing a failed business under a different name.

What public registers tell you: ABN Lookup (abr.business.gov.au) shows when the ABN was registered. ASIC Connect (connectonline.asic.gov.au) shows when the company was incorporated. Both are free.

What they don't tell you: Entity age is not the same as trading experience. A company registered six months ago may be run by a director with twenty years in the industry, or it may be a new entity picking up where a previously failed company left off, with the same director, the same phone number, and the same trade contacts.

A young entity warrants closer inspection of the director history, not automatic rejection. The question is: why is this entity new?

Q2: Does the builder have a current licence?

Why does this matter to you?

A builder without a current contractor licence (Building) cannot legally contract with you for residential building work over $5,000. A non-compliance entry is one of the clearest public indicators of prior consumer harm, because it means a compensation order was made and not complied with.

What public registers tell you: Verify NSW (verify.licence.nsw.gov.au) shows whether the licence is current, the licence category, expiry date, any conditions, public warnings, penalty infringement notices, and, critically, non-compliance with a tribunal order.

Non-compliance is the entry that matters most. If a builder fails to comply with a compensation order, their licence can be suspended and the non-compliance is recorded on the public register indefinitely. If you see it, the builder was ordered to pay compensation for building work and did not.

What public registers don't tell you: Historical suspensions that have since lapsed are not always visible. A contractor licence also confirms legal eligibility to contract; it does not assess competence, current workload, or financial capacity.

A contractor licence (Building) is required for any residential building work over $5,000. A Qualified Supervisor Certificate does not authorise a person to contract with you, only to supervise.

Q3: Does the builder have mandatory insurances?

Why does this matter to you?

Without HBCF coverage, you have no statutory safety net if the builder becomes insolvent, disappears, or dies mid-project. For contracts over $20,000, the builder cannot legally accept your deposit without a Certificate of Insurance in place. Public liability and workers compensation gaps expose you to liability for site accidents on your own land.

What public registers tell you: The NSW HBC Check portal confirms whether a Certificate of Insurance exists for a specific project, the contract details it covers, and whether any prior claims have been paid on it.

What public registers don't tell you: Whether the builder has OJV (Open Job Value) capacity to take on your project. Each eligible builder has an HBCF capacity limit, the maximum total value of insured projects they can hold at once. A builder at their limit cannot obtain a Certificate of Insurance for your project regardless of their licence status. This information does not appear on any public register.

Public registers also cannot verify the authenticity of a public liability or workers compensation certificate of currency provided directly by the builder.

For the full two-phase HBCF process, including what to check before signing and after the contract is in place, see How to Verify a Builder's HBCF Insurance in NSW.

Q4: Has the builder been subject to any regulatory sanctions?

Why does this matter to you?

Regulatory sanctions sit above commercial disputes. A public warning notice from the ACCC means the regulator considered it in the public interest to warn consumers about alleged conduct. A SafeWork NSW prosecution means a court has found that the builder's site management exposed workers to serious harm. Both signals indicate a pattern of non-compliance that goes beyond a single customer dispute.

What public registers tell you:

The ACCC Public Warning Notice Register (accc.gov.au/public-registers/public-warning-notice-register, free) lists notices issued under section 223 of the Australian Consumer Law. The ACCC may issue a public warning notice when it has reasonable grounds to believe a business is engaging, or has engaged, in conduct that contravenes the ACL and that issuing a notice is in the public interest. This is a discretionary, high-threshold action: the ACCC uses it when a credible risk to consumers exists and immediate court action is not possible. Entries include the entity name, the date of the notice, and a description of the alleged conduct.

SafeWork NSW Prosecutions (safework.nsw.gov.au/compliance-and-prosecutions/prosecutions, free) publishes outcomes of prosecutions brought under the Work Health and Safety Act 2011 (NSW). The register is organised by year and lists the defendant name, conviction date, a description of the incident, the charges, the court, and the penalty imposed. Construction prosecutions are common: scaffold collapses, falls from height, excavation failures, and unsafe plant are recurring categories. A building company that appears on this register has been convicted of a criminal offence for exposing workers to risk of death or serious injury.

SafeWork NSW also issues improvement notices (requiring specific corrective action within a timeframe) and prohibition notices (stopping dangerous work immediately). Prohibition notices on an active construction site bring all work to a halt.

What public registers don't tell you: The ACCC register covers consumer-facing conduct under the ACL but does not capture disciplinary actions by Building Commission NSW or industry bodies, which appear on the Verify NSW licence register (Q2 above). SafeWork prosecutions cover completed criminal proceedings; improvement and prohibition notices, which are more numerous, are issued administratively and are not centrally published in a searchable register.

Q5: Is there a history of disputes or tribunal appearances?

Why does this matter to you?

Published NCAT decisions are the closest thing to a consumer complaint record available in the public domain. A builder with multiple decided cases has had their conduct formally assessed and found wanting. Non-compliance with a tribunal order is the clearest flag: the builder was found liable, ordered to compensate a homeowner, and refused. That record remains permanently visible on the Verify NSW licence register.

What public registers tell you: NSW Caselaw (caselaw.nsw.gov.au) publishes a selection of NCAT decisions, including the Consumer and Commercial Division which handles residential building disputes up to $500,000. Search by the builder's exact legal name. Published decisions include the outcome, the parties, and the amount at issue.

What public registers don't tell you: Many NCAT matters are resolved at conciliation. Conciliation resolutions leave no public record. A clean NSW Caselaw result means no published decisions exist, not that no disputes have occurred.

Court cases (Federal Court, NSW Supreme Court, District Court) sit on separate databases (caselaw.nsw.gov.au and austlii.edu.au). A thorough search requires checking both.

Any non-compliance with a tribunal order will already appear on the Verify NSW licence register (Q2 above). That is the most important single indicator: the builder was ordered to pay and refused.

Q6: Do the directors have insolvency history?

Why does this matter to you?

A disqualified director cannot legally manage a corporation. If your builder is being managed by a disqualified director, that is a major governance and legal-risk signal. It does not automatically void your contract, but it raises serious questions about compliance, authority, and business integrity. A director who has personally gone bankrupt, or who has been associated with successive collapsed companies, represents a pattern risk. The pattern is only visible when the director's history is checked across all entities they have controlled, not just the current one.

What public registers tell you: The AFSA National Personal Insolvency Index ($15 per search at services.afsa.gov.au) records all personal insolvency proceedings in Australia since 1928: bankruptcies, debt agreements, and personal insolvency agreements. The ASIC Banned and Disqualified Register (free) shows whether any director is legally disqualified from managing a corporation.

To run either check, you first need the director names. Director names and company history can be obtained from ASIC searches and extracts, for a fee, at ASIC Connect.

What public registers don't tell you: Whether a director has been associated with multiple failed entities in the same trade. That pattern (same director, successive liquidations) requires cross-referencing the historical extract against insolvency notices across multiple entities, which is time-consuming to do manually.

For the full process including how to read the results, see How to Check a Builder's Financial Background in NSW.

Q7: Is there any history of company insolvency actions?

Why does this matter to you?

If your builder enters external administration mid-project, work stops immediately and you become an unsecured creditor. In most construction insolvencies, unsecured creditors recover very little or nothing. ASIC Published Notices lets you see whether formal proceedings have already started. Financial stress that has not yet reached that threshold is only visible through commercial credit data covered in Q9.

What public registers tell you: ASIC Connect shows the current company status: Registered, Under External Administration, Deregistered, or Under Receivership. ASIC Published Notices (publishednotices.asic.gov.au, free) lists statutory demands (formal demands requiring a company to pay a debt within 21 days) and winding up applications, which appear before a company formally collapses.

What public registers don't tell you: A statutory demand or winding up application appears only after a creditor has exhausted informal options and escalated to formal legal process. Financial stress that has not yet reached that threshold leaves no public trace. A company can be in serious difficulty, with slow-paying suppliers, disputed subcontractor invoices, and stretched credit lines, without anything appearing on a register.

Q8: Does the builder have established trade supply arrangements?

Why does this matter to you?

A builder without settled supplier and subcontractor relationships is a construction risk regardless of their licence status. Material supply delays, unavailable subcontractors, and supplier credit restrictions all translate directly into project delays and cost overruns. A builder who pays their suppliers promptly maintains the relationships needed to keep your project moving.

What public registers tell you: The PPSR (ppsr.gov.au, $2) provides indirect evidence. A PPSR organisation search by the builder's ACN shows every registered security interest against the company's assets. For an active construction business, this typically includes Purchase Money Security Interests (PMSIs) lodged by trade suppliers, including timber merchants, plumbing suppliers, and electrical wholesalers, who retain title over materials until payment is received. Multiple PMSI registrations from recognisable trade suppliers indicate active, ongoing supply relationships. A builder with no PPSR registrations at all may own their equipment outright (a positive sign) or may have no established trade credit lines, a different kind of signal worth exploring.

What commercial credit reports add: Credit bureau trade lines from a credit bureau report reveal the same supplier relationships from a payment perspective: which suppliers are extending trade credit, at what volume, and whether payments are being made on time. A builder with active trade lines across multiple suppliers has established relationships; a builder whose trade lines show slow payment or recent account restrictions may be losing supplier goodwill before anything appears publicly.

There is no public register of subcontractor relationships directly. A builder who cannot name their key subcontractors, or whose usual trades are unwilling to work with them, may be facing supply-side pressure that will not appear anywhere until the project stalls.

Ask the builder directly: who are your key subcontractors and material suppliers, and how long have you worked with them? The PPSR and a credit report provide the data context for evaluating the answer.

Q9: Does the builder pay their bills on time?

Why does this matter to you?

Payment behaviour is the most predictive indicator of financial distress available before formal insolvency. A builder 90 days overdue to its suppliers has already begun failing its creditors. By the time a court judgment appears in a public register, the situation has typically been deteriorating for months. A commercial credit report surfaces this before it reaches the courts, giving you an early picture that no free register provides.

What public registers tell you: Public signals of payment failure include court judgments on NSW Caselaw and AustLII, statutory demands and winding-up applications on ASIC Published Notices, and PPSR registrations indicating secured-creditor activity ($2 per search at ppsr.gov.au).

What public registers don't tell you: Slow payment that has not yet escalated to formal proceedings. A builder who routinely pays subcontractors 60 days late, disputes invoices to extend terms, or retains money on completion is a poor credit risk, but none of that appears on any register until a creditor takes legal action.

What commercial credit reports add: This is where a commercial credit report makes the biggest difference. Three data sources not available in any public register:

• Average days to pay trade invoices. Credit bureaus aggregate payment timing data from accounting integrations and member networks. A builder consistently paying 60 or 90 days past terms is identifiable before any formal action is taken.
• Registered B2B payment defaults. Credit bureaus operate proprietary registries that capture trade payment performance and allow creditors to formally register a default when an invoice is overdue and disputed. Payment overdue records generally appear before defaults, which in turn appear before court action. The further a debt progresses through this cycle, the greater the insolvency risk.

A commercial credit report on a building company can be ordered by any homeowner without the builder's consent. The Privacy Act's consumer credit provisions apply to natural persons, not corporations.

The infomration on a commercial credit report matters. Particularly in the context of a market where subcontractor payment disputes are the precursor to the insolvency events described in Q7.

What you can find yourself, and what you can't

Most of the public register searches above are free and can be completed in an hour or two. All the relevant registers are linked in one place at TrustSignal Public Registers.

But public registers have a structural limit: they record what has been formally filed. They do not surface a builder's current OJV utilisation, their informal payment behaviour, their subcontractor relationships, or cross-entity patterns that require aggregating multiple sources.

A TrustSignal Builder Report answers all nine questions in one place, combining public register data with proprietary datasets to give you a single, structured picture of a builder's background in minutes. For NSW residential building contracts where deposits of $50,000 to $150,000 or more are at stake, that is the level of diligence that matches the risk.

Frequently Asked Questions

Is it free to check a builder's licence in NSW?

Yes. Verify NSW at verify.licence.nsw.gov.au is free, requires no account, and can be searched by name, licence number, ABN, or suburb.

What if my builder has no HBCF insurance?

For contracts over $20,000, HBCF must be in place before the builder accepts any payment. If coverage is missing, withhold payment and contact Building Commission NSW on 13 32 20 before proceeding.

How do I know if a builder is financially stable?

No single public record answers this directly. The combination of ASIC company status, ASIC Published Notices (statutory demands), NSW Caselaw (court judgments), PPSR (writs), and AFSA personal insolvency data provides the most complete public picture. See our financial background check guide for the full process.

What should I check before paying a deposit?

Three things must be confirmed first: a current contractor licence (Q2), a Certificate of Insurance for your specific project (Q3), and that the deposit does not exceed 10% of the contract price, the legal maximum under the Home Building Act 1989.

What does a TrustSignal Builder Report include?

A TrustSignal Builder Report covers all nine questions above: business history, licence, insurance, regulatory sanctions, disputes, director insolvency, company insolvency history, trade supply relationships, and payment behaviour, sourced from public registers and proprietary datasets, delivered in a single structured report.
