How to check a Victorian builder or contractor registration

Start with the Building and Plumbing Commission (BPC) guidance on engaging a builder. Match the contracting individual or company, registered category, work class, and conditions to your project. A builder registration does not replace project insurance, permits, or specialist trade checks.

This guide was reviewed against the linked official sources on 13 October 2026. It provides general information, not legal advice.

Step-by-step: check the holder and authorised work

1. Collect the right identity. Use the registration number and legal name from the quote or contract. Distinguish an individual practitioner from a registered company and any trading name.
2. Choose the appropriate official register. Follow the BPC links for building practitioners or plumbers. Electrical workers and contractors are regulated separately by Energy Safe Victoria.
3. Read the permitted scope. Check category, class, conditions, and official status. Follow up an unclear identity, suspension, cancellation, or scope mismatch with the regulator before relying on the result.
4. Check the project separately. Confirm approvals, the contract, and the applicable insurance or Home Warranty cover. Retain the evidence and date of your check.

Registration categories have different jobs

The BPC is the current building and plumbing regulator; older records and terminology may refer to the Victorian Building Authority (VBA). A registration category determines the kind of professional work permitted. It is not a guarantee of suitability for every project.

• Domestic builders: distinguish Domestic Builder Unlimited from Limited classes and conditions. Limited registration applies to specified work; even a broad class must be read with its conditions and exclusions. See domestic builder classes.
• Commercial builders: commercial registration does not automatically establish authority for the domestic work you propose.
• Building surveyors: perform a separate building certification role. Check the appropriate registration rather than treating a builder result as surveyor authority.
• Plumbing and electrical work: use the appropriate occupation, class, and regulator. A building registration alone does not establish specialist trade authority.

The BPC explains when registration is required and relevant exceptions. Avoid assuming that every small repair has identical licensing or insurance requirements.

Home Warranty and earlier DBI policies

The Victorian Government Home Warranty guidance states that Home Warranty began on 1 July 2026 for new eligible domestic building contracts signed on or after that date. It generally applies to eligible work valued at more than $20,000 and homes of three storeys or less, subject to scope, limits, and exclusions.

Earlier Domestic Building Insurance (DBI) policies remain with the insurer that issued them and do not transfer automatically to Home Warranty. The applicable scheme depends on contract and insurance dates. The BPC explains the DBI and Home Warranty transition. Do not apply legacy DBI thresholds, claim triggers, or time limits to every new contract.

Ask for the applicable project cover evidence and confirm its details and timing requirements with the BPC or insurer. A register entry or general insurance eligibility is not proof that your particular job is covered.

Problems with a registration or building work

Unregistered work where registration is required can lead to enforcement. Penalties depend on the offence and current law; this guide does not publish a fixed dollar estimate. A licensing problem does not establish that every statutory warranty or complaint right is lost. Consumer Affairs Victoria explains implied warranties.

Use the BPC complaint guidance to identify the relevant route. For an existing project, seek regulator and qualified advice before changing contractual payments or terminating work.

Using WorkClear for repeat checks

WorkClear's VIC verification page leads to supported coverage and the existing account/search workflow. Check Sources and Status before relying on stored records; source updates do not establish a live check of an individual result. A missing or unavailable result does not establish that a person is unregistered.

The contractor API supports repeat checks across available source families. Match the holder and scope, retain the response evidence, and send unresolved results to manual review. Insurance and project approval decisions remain separate.
