Buy the evidence as well as the finish
A new kitchen or roof can make an existing dwelling feel like a low-risk purchase. The acquisition question is more precise: which residential work was carried out, by whom, and what evidence supports any claimed insurance protection? SIRA’s homeowner guidance advises buyers of recently built or renovated homes to check the certificate included with the sale contract and speak to their solicitor or conveyancer if uncertain. Make that a defined pre-signing enquiry. Do not let a polished inspection presentation stand in for a documented work history.
Start with the work timeline
Ask the seller for a dated list of substantial building works, the responsible contractors, available contracts, invoices and completion documents. Separate original construction from later additions. A certificate for the initial house may not describe a subsequent extension. Give the same timeline to your conveyancer and independent inspector so documentary questions and physical observations can be compared. Where dates are approximate, label them as unconfirmed rather than calculating a remaining protection period from an agent’s recollection.
Search using more than the street address
The free Service NSW HBC Check can be searched by certificate number, contractor details or insured address. Its returned information includes the certificate issue date, work address, contractor name and licence number, and claims paid on that certificate. Save a dated result. Where the property address has changed after subdivision or renumbering, ask the solicitor to reconcile the land identity instead of deciding that the first empty search proves there was no cover. Preserve the exact search inputs for follow-up.
Make mismatches visible
Use a comparison sheet with rows for work description, property identity, contractor, certificate and dates. Put the seller’s document beside the public result. If the certificate describes a smaller scope, another entity or an apparently different site, ask the insurer or SIRA what further evidence is needed. Keep the original documents unchanged. A verbal assurance that two companies are related is not an explanation of which business performed the insured work. Record who resolved each discrepancy and attach their written response.
Keep insurance and condition separate
SIRA explains HBC as a last-resort protection with claim requirements and limits. A certificate should not become a reason to skip a building inspection. Ask the inspector to report observed defects and inspection limitations, then ask the solicitor how those findings affect the proposed contract and any insurance enquiries. If a defect is identified, obtain prompt advice about notification and time limits. This article cannot calculate a claim deadline or promise that a particular loss is insured.
A retained-house subdivision example
Suppose a buyer plans to retain a renovated front dwelling and develop land behind it. The seller supplies one certificate, but the site visit reveals an added rear room not clearly described in the work records. Treat three questions separately: what work the certificate relates to, the condition and approval history of the room, and whether retaining it affects access or the proposed subdivision. Ask the conveyancer to coordinate the first enquiry and the inspector to assess condition. Refer planning implications to the town planner only if the retained structure affects the concept. Do not turn an insurance search into a yield approval.
TPC deal lens: close the acquisition gap
Before the contract becomes unconditional, identify which mismatches must be resolved, which further searches are authorised and which risks remain in the price. Allow for inspection and legal enquiries explicitly; do not assume an insurance payout will fund rectification. You are not expected to interpret policy wording yourself. Give the specialists the complete evidence and ask for a decision-ready answer: proceed on what conditions, seek further information, or reconsider the purchase. Key takeaway: a genuine certificate is one input into due diligence, not a substitute for it. Your turn: which renovation in your target property has the weakest paper trail?
Your decision checklist
- Obtain the renovation timeline and complete sale-contract certificate.
- Save the dated HBC search inputs and result.
- Refer entity, address and scope mismatches to the solicitor and insurer.
- Keep inspection findings and insurance enquiries as separate decision items.

Frequently asked questions
Does an HBC search replace a building inspection?
No. A register concerns insurance information; a qualified inspector assesses physical condition and reports inspection limitations.
What if the street address changed?
Preserve the search inputs and ask your conveyancer to reconcile the current and former property identifiers with the insurer or SIRA.
Does one certificate cover every later renovation?
Do not assume so. Reconcile each material work stage with the actual insured description and obtain advice on gaps.
Can a paid claim appear in the register?
Service NSW says the register provides information about claims paid on a certificate. Ask the insurer what that means for your circumstances.
Who should resolve contradictory documents?
Your NSW solicitor or conveyancer should coordinate the contract enquiry; SIRA or the insurer should clarify insurance information.
