Decision Regulatory Impact Statement: Reforms to plumbing legislation

On 27 November 2019, the Department of Mines, Industry Regulation and Safety – Building and Energy Division (Building and Energy) published a decision paper marking the end of an extensive review of Western Australia’s plumbing laws.

The decision paper – formally titled Decision Regulatory Impact Statement: Reforms to plumbing legislation in Western Australia (the ‘DRIS’) – sets out the legislative changes that are intended to be made and covers 20 separate reforms.

Each decision in the DRIS takes into account the feedback that was provided in the more than 1,000 submissions received in response to a Consultation Regulatory Impact Statement released by Building and Energy in May 2018.

The broad areas of reform covered in the DRIS are:

  • The funding model for plumbing regulation

  • The future role of the Plumbers Licensing Board

  • The definition and scope of regulated plumbing work

  • The testing and maintenance of plumbing safety devices

  • Minor plumbing repairs by private homeowners in their own homes

  • The requirements for modular plumbing installations

  • The regulation of plumbing designers and plumbing design verifiers

  • The scope of work covered under a restricted plumbing permit

  • The transition from apprentice to tradesperson

  • Advertising to perform plumbing work

  • Supervision and general direction and control by Licensed Plumbing Contractors

  • Penalties and prosecution

  • Compliance notification for ‘minor plumbing work’

Further information, including a summary of each reform, is available at A copy of the DRIS itself is also available from this webpage.
