Gas Compliance Certificate QLD: Who Needs One and When
Short answer: A gas compliance certificate in Queensland is issued by a licensed gas fitter every time a gas system is installed or altered. It is lodged digitally through the Resources Safety and Health Queensland (RSHQ) Portal under the Petroleum and Gas (Production and Safety) Act 2004, and an original copy goes to the property owner.
What the certificate actually certifies
A gas compliance certificate is the licensed gas fitter's formal declaration that the gas work they just completed, whether that is a new cooktop, a hot water system, a gas heater or a full LPG installation, meets the safety standard required under Queensland law. The Queensland Gas Association puts it plainly: gas installers must issue a gas compliance certificate at the end of any installation or alteration, and it is described as the only way to declare that a gas installation and its appliances are safe to operate.
There is no fixed expiry date on the certificate itself. It simply reflects the condition of the system as at the date the work was signed off. If nothing changes, in theory the certificate stands. The moment you add an appliance, move a gas line, or alter the system in any way, a new certificate is required for that new work.
Who is legally required to issue it
Only a person holding a current Queensland gas work licence or gas work authorisation can legally perform gas fitting work and issue the certificate. Business Queensland's own consumer guidance is direct about this: before you hire someone, check the register to make sure a gas licence or authorisation is current and that it covers the work to be performed. You are entitled to ask for a licence number and confirm it yourself before any work starts.
The certificate is lodged through the RSHQ Portal, the online system Resources Safety and Health Queensland runs for gas work licensing and compliance. When an installation is completed, the licensed fitter uses the Portal to issue the property owner or system operator with an original copy of the gas system compliance certificate, and a matching record is kept with the regulator.
When you need one
The trigger is always the gas work itself, not a calendar date. A new gas installation, an alteration to an existing system, adding or replacing an appliance connected to reticulated natural gas or LPG, and reconnecting a system after it has been disconnected can all require a fresh certificate. If you are only servicing an appliance without altering the gas fitting (a routine heater clean, for example) that is different again, and doesn't necessarily trigger a new compliance certificate on its own; ask the fitter you engage to confirm which applies to your job.
Two situations trip people up specifically: selling a property, and gas hot water replacement. See our guide on gas compliance certificates when selling a house in QLD for how the sale situation works, and our Form 4 gas QLD guide for why gas hot water replacement often needs a QBCC Form 4 alongside the gas compliance certificate.
Frequently asked questions
Does a gas compliance certificate in QLD expire?
No fixed expiry date applies to residential certificates. It reflects the system as installed; any further gas work needs its own new certificate.
Who can issue a gas compliance certificate in Queensland?
Only someone holding a current Queensland gas work licence or gas work authorisation. Check the licence register before hiring.
