Key points at a glance
- Builders doing Restricted Building Work are on the LBP public register.

- Electrical workers are on the EWRB register.
- Checking a licence is free, fast and the best protection against unqualified work.
Which register to use
For building work that affects structure or weathertightness, check the Licensed Building Practitioner (LBP) register and confirm the licence class matches the job. For plumbing, gasfitting and drainlaying, use the PGDB register. For any electrical work, use the EWRB register.
Ask the tradesperson for their name and registration or licence number, then confirm it directly on the official register rather than relying on a certificate they show you.
Other checks before you hire
Get several written quotes, ask for references and recent examples of similar work, and confirm they carry appropriate insurance. For larger jobs use a written contract — the law requires one for residential building work over a set value and requires certain disclosure information to be provided.
Be cautious of anyone who wants a large cash deposit up front, pressures you to skip consents, or cannot provide a licence number.
For homeowners
- Verify licence numbers on the official register yourself before you hire.
- Use a written contract for larger jobs and keep all documentation.
- Never agree to skip a required consent or certificate.
For tradespeople
- Make your licence number easy for clients to find and verify.
- Provide the required disclosure and written contract for residential work over the threshold.
- Keep your registration and practising licence current.
