What a plumber in Western Australia has to hold
In Western Australia plumbing work can only be done by someone licensed by the Plumbers Licensing Board, and minor tasks like swapping a showerhead are excluded. Gas is separate, WA issues its own Class G gasfitting permit, so ask for that licence before gas work starts.
The full Western Australia rules, thresholds and certificates are on the state licence guide. Check a licence yourself: Building and Energy online licence search. Sources: www.wa.gov.au, read 15 Sep 2026 · www.wa.gov.au, read 15 Sep 2026.
Who runs the water in Mandurah
A plumber answers to two bodies most people never think about until the sewer backs up. Knowing which is which saves a phone call.
What to ask before you say yes
Ask for the licence number and check it on the register before any money changes hands. In most states the business holds a contractor licence and the person on the tools holds their own, so ask which one you are looking at. And ask for a written quote with GST in it, if that gets a shrug, that is your answer.
How the request works
You describe the job in your own words, you pick which businesses get it, and it goes to them and to nobody else. Nobody pays for your request.

Questions people in Western Australia ask
Do I need a licensed plumber for a hot water system in Western Australia?
Yes. WA says plumbing work on water supply, sanitary or drainage systems can only be done by a person licensed by the Plumbers Licensing Board, and a hot water connection is water supply work. Ask for the contractor's licence number and check it on the Building and Energy search before they start.
Can the same plumber do the gas work?
Only if they hold a WA gasfitting permit. The plumbing licence covers water supply, sanitary and drainage work; gas is a separate Class G permit for natural gas and LPG. Ask to see it. A plumber without it has to bring in someone who holds it.
Is this every plumber in Western Australia?
No. It is what the Yamate directory holds for these postcodes on the date at the top of the list, and nothing more. A good plumber can be missing from it. A listed one has not been checked by us. The register is the authority, not this page.

General information only, not legal advice. Yamate is not a regulator and has not checked any licence, any insurance or any work on this page; the state register is the only place a licence can be confirmed. Business names, suburbs and services come from the Yamate directory on the date shown and may be out of date. The founder plan is $19 a month flat if you sign up before 30 November 2026, $29 a month after — that is the software for tradies, and it has nothing to do with whether a business appears here.
