Whose name goes on a plumbing job

In New South Wales, Western Australia, Queensland, South Australia and Tasmania, contractor is a licence of its own. Victoria licenses individuals only. Every place draws its own line for who signs a finished job off, and its own days to hand the paper over: from 2 days on the New South Wales Central Coast to 10 business days to lodge the Form 4 in Queensland.

How to read the line

  1. The rung A rung is one licence class, drawn in that place’s own words, lowest rung first. The foot of every ladder is the same: no licence at all.
  2. The line A copper border marks the class whose holder may put their name to the finished job. Where a law names the person rather than a class, a copper bar stands beside the ladder instead. Tasmania's and the gas ladder's sources name no class, so those two are left unmarked.
  3. The days The chip under each ladder gives the document a finished job should leave, and the days, or the stage, allowed to hand it over; where that depends on the job, the chip points to the paperwork guide instead. Every chip says what it rests on in the sources for this page.

Day counts are set upright when the source says plain days and in italic when they are business or working days, because they are not the same length. “2 days, coast” is the Central Coast’s own rule, the shortest count drawn here.

Where the states disagree

In New South Wales, work done by a tradesperson certificate holder is signed off by the holder of a contractor licence or a qualified supervisor certificate. In Victoria, only a licensed plumber may issue a compliance certificate, never a registered one. Building Commission NSW Building and Plumbing Commission

Queensland asks the relevant person for a Form 4, lodged with the QBCC within 10 business days after notifiable work is finished. South Australia asks for an electronic certificate of compliance, signed by the tradesperson and by any contractor involved in the work. Plumbing and Drainage Act 2018 Office of the Technical Regulator

Western Australia gives 5 working days for the certificate of compliance. For certain plumbing or drainage work that needs no building permit, the Northern Territory gives 7 days for the notice of completion and certificate of compliance. Building and Energy Northern Territory Government
