Look the fitter up before they arrive
Queensland splits gas licensing from plumbing licensing. Gas work licences and authorisations are issued through Resources Safety and Health Queensland (RSHQ), and the QBCC says anyone doing or supervising gasfitting must also hold the gasfitting occupational licence from the Chief Gas Examiner and RSHQ.
The RSHQ Portal lets anyone search current licence and authorisation holders, no account needed. Check two things: that the licence is current, and that it covers your job, because not every holder may do every type of gas work.
Gas on the Sunshine Coast
No rule pushing gas hot water out
Unlike Victoria, Queensland's hot water guidance doesn't restrict replacing a gas system, so a like-for-like gas swap is still an option here.
A tempering valve either way
Queensland requires a temperature control device on all new and replacement hot water systems, gas included.
Cylinders or a meter
Before connecting another appliance, the fitter must confirm the supply can cope. That means checking LP gas cylinder storage and vaporisation rate, or meter capacity, plus the pipe sizes.
From booking to certificate
Describe the job
Say what's being added, moved or removed, and if your gas comes from cylinders or a meter.
Check the licence
Search the fitter's name or number on the RSHQ Portal.
Supply check
The fitter confirms your gas supply can carry the extra demand before anything new is connected.
Certificate on the day
When the installation or alteration is finished, the fitter must issue you a gas system compliance certificate through the RSHQ Portal, and send a copy to the network operator within 5 days.
Plates, notices and what to keep
Queensland changed the compliance plate rules in July 2025. Most gas installations no longer get a physical plate, though caravans still do. The certificate is your record, so store it with your house documents.
If the fitter has safety concerns about any part of your gas system, they must give the owner or operator a defect notice. Ask them to explain it, and what fixing it involves.
Common gas jobs
- Fitting or moving a cooktop
- A new bayonet for a heater or barbecue
- Replacing gas hot water
- Gas safety checks on older appliances
- Disconnecting and capping gas you no longer use
Ask the gas fitter
- Does your gas work licence cover this appliance and this type of work?
- Will the existing pipes and supply handle the new appliance?
- When will I receive the gas system compliance certificate?
- Did you find anything unsafe that needs a defect notice?
What we would do
Ask for the gas licence number when you book and check it on the RSHQ Portal while you wait. Tell the fitter if you use bottles or a meter, so they can plan the supply check. On the day, don't sign off until you've received the compliance certificate. If you're replacing gas hot water, compare it against a heat pump or solar quote before you decide: Queensland lets you choose. A licensed gas fitter who does this work every week will be happy to be checked.
