Plumbing Licensing & Rules in Western Australia
Important regulations and resources to help you hire with confidence in Western Australia.
Plumbing Contractor Licence
A valid plumbing contractor licence issued by the Plumbers Licensing Board (within the Building and Energy division) is required to contract for or carry out water supply, sanitary and drainage plumbing work in Western Australia. Tradespersons must also be licensed to carry out plumbing work under supervision.
Gasfitting Permit
Any work involving gas installations or repairs requires a separate gasfitting permit in addition to a plumbing licence. Only authorised gas fitters may undertake gas work.
Plumbing Certificates of Compliance
Licensed plumbing contractors must issue a Plumbing Certificate of Compliance for all completed notifiable plumbing work. Certificates must be lodged with the Plumbers Licensing Board within the statutory period and provided to the customer.
Work Health and Safety
Plumbing businesses must comply with Western Australia’s occupational safety and health legislation and, where they employ staff or undertake high‑risk activities, register with WorkSafe WA and maintain workers’ compensation insurance.
Public Liability Insurance
Although not prescribed by legislation, plumbing contractors are encouraged to hold public liability insurance—generally at least $10 million—to protect against claims for property damage or injury arising from their work.
