About licensed plumbers in Toowoomba

In Queensland, most building work valued over $3,300, including labour and materials, must be carried out by a contractor holding a QBCC licence of the right class. Some work needs a licence at any value, including plumbing and drainage, fire protection, building design and site classification.

A licensed plumber in Toowoomba holds a licence from the Queensland Building and Construction Commission (QBCC) that names the classes of work they may carry out. The licence has to be held by the business you sign with: a director's personal licence does not cover their company, and a licence in one class does not cover work in another.

TradesField reads QBCC and the Australian Business Register and lists every company with a plumbing & drainage class in Toowoomba. Licence status is free to check. The Construction Background Report adds court, adjudication, ASIC and licence conduct records, graded A to E.
