When to lodge a certificate of compliance

When major plumbing work is completed, the licensed plumbing contractor who lodged the notice of intention for the work must submit a certificate of compliance within five working days of completing the work.

A certificate of compliance can only be lodged by the licensed plumbing contractor to which it is registered and must be filled out in its entirety. Partially filled or unreadable certificates will not be accepted.

What happens if the work is not completed?

If for any reason a licensed plumbing contractor commences plumbing work but will not complete all of the work identified in the notice, the plumbing work carried out must be certified. However, the plumbing contractor must modify the notice of intention submitted to the Building Commission to accurately reflect the work that has been carried out by completing the reverse side of the certificate of compliance.

If a licensed plumbing contractor submits a notice of intention to the Plumbers Licensing Board (the Board) but the licensed plumbing contractor has not commenced and will no longer be responsible for carrying out any of the plumbing work specified in the notice, the contractor must withdraw the notice by completing the reverse side of the certificate of compliance and submitting it to the Board.

How to lodge a certificate of compliance

Within five working days of completing any major plumbing work, a licensed plumbing contractor must:

  • complete, sign and date the certificate of compliance;
  • provide the original certificate of compliance (yellow copy) to the Board;
  • provide a copy of the certificate of compliance (blue copy) to the owner or occupier of the property where the plumbing work was carried out;
  • where drainage plumbing work is carried out:
    • provide a copy of the certificate of compliance (pink copy) together with any as constructed diagram to the local government authority in non-sewered areas; or
    • provide a copy of the as constructed diagram to the licensed water services provider in sewered areas; and
  • retain a copy of the certificate of compliance (green copy) for six years.

Certificates of compliance can be lodged in person at the Building Commission, any Department of Mines, Industry Regulation and Safety (DMIRS) regional office or by posting to:

How to order notices and certificates

Notices of intention and certificates of compliance are able to be purchased by licensed plumbing contractors or their representatives. The certificate numbers purchased will be recorded against the licensed plumbing contractor and only that licensed contractor will be able to submit them. This means that notices or certificates will not be transferable from one licensed plumbing contractor to another.

Current prices for a notice of intention and corresponding certificate of compliance are available by downloading the certificate order form or contacting the Board.  A discount applies if purchasing notice of intention and compliance certificates in multiples of 10 or 20. A discount for a multi-entry certificate will apply if a book of 12 is purchased. Fees associated with certificates will include GST.
