Establishment and function

The Plumbers Licensing Board is established by Part 5A of the Plumbers Licensing Act 1995.  The Act vests the Board with four main functions:

  • To monitor matters relating to the qualification and training of plumbers.
  • To advise the Minister for Commerce on matters relating to the licensing and regulation of plumbers.
  • To administer the plumber licensing scheme.
  • To perform licensing and disciplinary functions.

The Board issues plumbing contractor and tradesperson licences to suitably qualified and experienced applicants, and through the services provided by Building and Energy, administers the licensing system and the disciplinary framework that applies to licensed plumbers in Western Australia.

The Board has been operating since 2000 and comprises a maximum of nine members appointed by the Minister for Commerce.  Members are appointed as experts in matters related to plumbing occupations and to represent consumer interests.  The Chairperson is independent of the plumbing industry.
