Formal complaints
Last updated: 9 September 2026
If you are unable to resolve your problem by other means, you could consider applying to us for a determination or making a formal complaint.
Determinations explains what you can apply about and how to apply.
You might be able to complain to us about:
- a building consent authority
- a building contractor
- a licensed building practitioner
- a person doing or supervising restricted building work without a licence
- a building practitioner with other qualifications that enable them to do or supervise restricted building work.
Self-certified plumbing and drainlaying
If you used an endorsed plumber or drainlayer to self-certify eligible plumbing and drainlaying work and have concerns about their work, or a certificate of compliance, you can make a complaint to the Plumbers, Gasfitters, and Drainlayers Board.

If your concerns relate to decisions made by your BCA, including building consents or code compliance certificates, contact your BCA directly.
Other resolution options
If your building practitioner is not licensed or connected to any trade or professional body you will have to look at options other than making a complaint (for example, pursuing the matter through your contract, the Disputes Tribunal or the courts).
Resolution options includes dispute resolution, activating your consumer rights, contracts, Disputes Tribunal and the courts.
Contact us if you are unsure about what to do next.
