The NT Plumbers & Drainers Licensing Board, a statutory authority established under section 5 of the Plumbers and Drainers Licensing Act 1983, is responsible for issuing Advanced Tradesman licences and Journeyman registration cards.

The Board administers the Plumbers and Drainers Licensing Act 1983, which applies to declared plumbing licence areas PDF (109.6 KB). The Board ensures that only qualified persons obtain licences, registration cards and certificates. It is also responsible for assessing and maintaining standards of workmanship and for consumer protection through the investigation of complaints and, where appropriate, taking disciplinary action.

The Board functions in conjunction with other authorities which, under their respective legislation, require authorised plumbing and drainage works to be carried out by licensed tradesmen.

Forms and general information about plumbing licences are also available through the Territory Business Centres (TBC).

If you want to employ a plumber and cannot find his name on the list, contact the Registrar on (08) 8936 4083 to check that he is licensed in the NT.

Please note that a Journeyman is not a licensed plumber and cannot contract for work directly with a customer. All work carried out by a Journeyman must be supervised by an Advanced Tradesman. A list of currently registered Journeymen is available from the Registrar.

An Advanced Tradesman who wishes to certify (sign off) work must be registered as a Certifying Plumber and Drainer with the Building Practitioners Board.

If the Board does not have your current address you will not receive a renewal notice.
