How to Find a Licensed, Reliable Plumber (Checklist)
A good plumber is worth their weight in gold — a bad one costs you twice. This checklist gives you the concrete steps to verify a plumber is licensed, insured and reliable before you hand over money.
Verify the licence
In Australia, plumbers are licensed by state. Ask for their licence number and check it against your state's public register. A licensed plumber is accountable and has the required training and insurance.
Get it in writing
Ask for a written quote covering the work, parts, labour and any callout/trip fee. Avoid vague 'from $X' verbal estimates. A written quote lets you compare like-for-like and holds them to it.
Check insurance and reviews
Confirm they carry public liability insurance — that protects your home if something goes wrong. Read recent independent reviews, not just a few testimonials, and look for how they handle problems, not just praise.
Watch for red flags
Be wary of a plumber who wants a large deposit up front, can't provide a licence number, pushes unnecessary work, or refuses to put a quote in writing. A reputable plumber is transparent about price and process.
Common questions
Can I check a plumber's licence online?
Yes — most states have a public licence search. Ask for the number and look it up yourself.
What should a written quote include?
Breakdown of labour, materials, any trip/callout fee, an estimate of the total, and what happens if the job turns out bigger than expected.
Is the lowest quote always best?
No. A very low quote may mean lower-quality parts, no insurance, or extra charges later. Compare scope and reputation, not just price.
