Hiring Checklist for Cairns
- Ask about their backflow prevention accreditation — If you need annual backflow device testing — required by most water authorities — confirm the plumber holds a current backflow prevention accreditation, as not every licensed plumber is endorsed to test and certify these devices.
- Check whether they cover both water and drainage — In several states, plumbing and drainage are separate licence classes. A plumber licensed for water supply work may not be licensed for sewer and stormwater drainage, so confirm their licence covers the type of work you need.
- Confirm they will issue a compliance certificate — Licensed plumbers are required to lodge a compliance certificate with the relevant authority for regulated work. Ask upfront whether they will provide one — it is your proof the job was done to code.
- Ask who supplies the fixtures and fittings — Some plumbers mark up materials significantly. Ask whether you can supply your own WaterMark-certified tapware and fittings, or get a separate materials quote so you can compare retail prices.
- Verify they carry specialist tools for your job — Jobs like CCTV drain inspections, pipe relining, or thermostatic mixing valve testing require specialist equipment. Ask whether the plumber owns this gear or will subcontract, as subcontracting can add cost and delay.
Always ask your plumber for their Queensland Building and Construction Commission licence number before any work begins. You can verify it instantly on TradieVerify. A legitimate plumber will have no hesitation providing this.
- Refuses to provide a compliance certificate — A licensed plumber is legally required to lodge a compliance certificate for regulated work. Refusal or claims that "it's not necessary for this job" when the work clearly involves new pipework or fixture installation suggests the tradesperson may not be properly licensed.
- No WaterMark-certified products — All plumbing products installed in Australia must carry the WaterMark certification. If a plumber proposes using uncertified imported fittings to save money, the installation will not comply with the Plumbing Code and could void your insurance.
- Cannot explain the drainage plan — For any work involving sewer or stormwater connections, a competent plumber should be able to explain how waste will flow, where vents are located, and how the work ties into existing drains. Vague answers suggest a lack of planning that can lead to blocked drains or failed inspections.

Frequently Asked Questions
What is a compliance certificate and will my plumber provide one?
A compliance certificate (sometimes called a certificate of compliance) is a legal document confirming the plumbing work meets the Plumbing Code of Australia and state regulations. Licensed plumbers are required to lodge one with the relevant authority for regulated work such as new installations, re-routing pipes, or installing a hot water system. Always ask for a copy — without it, you may have difficulty selling your property or making an insurance claim.
How do I know if my hot water system needs replacing or just repairing?
Storage hot water systems typically last 8–12 years, while continuous flow (instantaneous) units can last 15–20 years. Signs it is time to replace rather than repair include rusty water from the hot tap, rumbling or banging noises from the tank, visible corrosion on the unit, water pooling around the base, or if the unit is more than 10 years old and requires a costly part. A licensed plumber can inspect the sacrificial anode and thermostat to give you an honest assessment.
Can a plumber also do gas fitting work?
Many plumbers hold a combined plumbing and gas fitting licence, but this is not automatic. Gas fitting is a separate licence endorsement in most states. If your job involves gas appliance installation or gas pipe work, ask to see proof of a current gas fitting licence or endorsement — do not assume a plumbing licence covers gas.
What plumbing work can I legally do myself in Australia?
Generally, homeowners can replace a tap washer, showerhead, or toilet seat, and clear a minor drain blockage with a plunger. Anything involving cutting into pipes, altering drainage, installing fixtures, or touching gas connections must be done by a licensed plumber. Doing regulated work yourself can void your home insurance and result in fines.
Why is there a call-out fee and what should it cover?
A call-out fee covers the plumber's travel time and vehicle costs to reach your property. It typically ranges from $60 to $100 during business hours and may double for after-hours or weekend callouts. The fee usually includes the first 15–30 minutes of diagnostic time. Always confirm call-out charges before booking, as some plumbers waive it if you proceed with the repair.
