How to Vet a Builder in NSW Before You Sign Anything
Choosing the wrong builder is the most expensive mistake you can make on a residential project — far more costly than any single contract clause. The good news: most problem builders leave a paper trail, if you know where to look. This guide walks through every check, in order.
Why vetting matters more than the contract
A good contract with a bad builder still ends badly — the contract just decides how the argument goes. A builder who becomes insolvent mid-build, abandons the site or builds defectively will cost you far more in time, money and stress than any single clause ever could.
The encouraging part: builders operate in one of the most regulated and documented industries in NSW. Licences, insurance, court records and company filings are all searchable. A pattern of problems is usually visible before you sign — if you actually look.
Do these checks before you pay a tender deposit or sign a preliminary agreement, not after. Once money has changed hands, walking away gets harder with every week.
Check 1 — Verify the licence, properly
Residential building work in NSW generally requires a current contractor licence, and you can check any licence free on the NSW Fair Trading online register. Most owners stop at 'the licence exists'. That's not verification — that's a glance.
Verify four things: the licence is current and not suspended; the licence class actually covers your type of work; the licence is held by the exact entity named on your contract — not a related company, not the director personally; and there are no conditions or disciplinary actions recorded against it.
The entity mismatch is the one that bites. If Smith Building Pty Ltd holds the licence but your contract names Smith Constructions Pty Ltd, you may be contracting with an unlicensed entity — which puts your insurance protection and your legal remedies at risk.
- Search the NSW Fair Trading register for the licence number on the tender or contract
- Match the licence holder's name and ABN exactly against the contracting entity
- Confirm the licence class covers your project (new dwelling, alterations, etc.)
- Note the licence issue date — a licence issued last year behind a company claiming 20 years' experience deserves a follow-up question
Check 2 — Look into the insurance history
Home Building Compensation (HBC) cover — formerly home warranty insurance — is compulsory for residential building work above a value threshold in NSW (currently
0,000 — check the current figure), and the builder generally must give you a certificate for your project before taking money beyond the deposit or starting work.
The insurance history tells you more than the certificate. icare's public HBC information lets you check a builder's cover, and a builder whose eligibility has been reduced, restricted or refused is a builder insurers consider risky — insurers see claims data you never will.
Also confirm current public liability and workers compensation insurance. If an uninsured worker is injured on your property, the exposure can reach you as the property owner.
- Ask for the builder's HBC eligibility confirmation and verify their cover through icare
- Never let work start (or pay beyond the capped deposit) without an HBC certificate naming your project
- Ask for currency certificates for public liability and workers compensation insurance
Check 3 — Search court and tribunal records
NCAT (the NSW Civil and Administrative Tribunal) hears most home building disputes, and its decisions are published and searchable — as are District and Supreme Court judgments. Search the builder's company name, trading names and directors' names.
You're reading for patterns, not incidents. One dispute across a long career means little — building is a dispute-prone industry and good builders get dragged into arguments too. A cluster of cases in the last two or three years, or repeated themes — defective work, abandoned projects, unpaid subcontractors — is a warning worth taking seriously.
Read how the builder behaved in the dispute, not just whether they won. A builder who rectified issues and engaged with the process is a different proposition to one who denied everything and disappeared between hearings.
- Search NCAT and NSW Caselaw for the company, its trading names and its directors
- Weigh recency and pattern over raw count — the last three years matter most
- Check NSW Fair Trading's public register of disciplinary actions and penalty notices
Check 4 — Assess financial health
Builder insolvency mid-project is the nightmare scenario — you lose time, money and often months in the insurance queue, and the next builder charges a premium to take over someone else's half-finished work. Financial distress is also visible before collapse, if you look.
Start with an ASIC company search: how long has the entity existed, who are the directors, and have those directors been behind previous companies that failed? A director on their third building company in ten years is running a pattern, not a business. Commercial credit reports add court judgments, payment defaults and insolvency notices.
Softer signals matter too: pressure for early or restructured payments, requests for money ahead of the payment schedule, suppliers on site mentioning they haven't been paid. Any of these mid-negotiation is a reason to slow down.
- Run an ASIC search on the exact contracting entity and its directors
- Search directors' names for previous deregistered or liquidated building companies
- Treat any request to pay ahead of the schedule — before or during the build — as a red flag
Check 5 — Ask the questions most owners don't
Paperwork tells you the past; a few direct questions tell you about your build. How many projects does the builder have running right now, and how many does their team realistically supervise well? Who is actually on your site day to day — a dedicated supervisor, or the director spread across eight jobs?
Ask to speak to the owners of their two most recently completed homes — not hand-picked references from years ago. Recent clients experienced the builder's current workload, current trades and current financial state. Two phone calls will teach you more than any brochure.
Finally, watch how the builder responds to being checked. A professional builder expects due diligence and answers easily. Defensiveness, vagueness or 'no one's ever asked that before' are answers in themselves.
- How many projects are you running right now, and who supervises mine day to day?
- Can I speak to the owners of your two most recently completed homes?
- Which subcontractors do you use regularly, and how long have they worked with you?
- What happens if you fall behind — how do you communicate delays?

- ASIC search done — company age, directors, and directors' previous companies
- No requests for payment ahead of the legal deposit cap or the payment schedule
- Spoken with owners of the two most recently completed projects
- Builder answered all vetting questions openly
Frequently Asked Questions
How do I check if a builder is licensed in NSW?
Search the NSW Fair Trading contractor licence register. Confirm the licence is current, the class covers your type of work, the licence is in the name of the entity you are contracting with, and there are no conditions or disciplinary actions recorded. A licence in a different name to the quote is a warning sign, not a technicality.
What insurance must a NSW builder have?
For residential work over
Warning signs include a trading entity only months old, licences recently moved from deregistered companies, court judgements, credit defaults, and a pattern of NCAT actions from unpaid subcontractors. Most of this is discoverable through company searches and record checks before you pay a deposit.
Helios Project Management runs an independent builder check — licence and registration verification, insurance and home warranty checks, company history and financial red-flag screening, and dispute history review — for a fixed fee of $450 inc. GST, with a written risk assessment and clear recommendation within 24 hours.
Ask how many projects they have running right now, who actually supervises your site day to day, and whether you can speak to the owners of their two most recently completed homes — not hand-picked references from years ago. Evasive answers to any of these are themselves an answer.
