A gas compliance certificate in Queensland is an official document that a licensed gas fitter gives you after installing or altering a gas system, certifying that the work meets the Australian gas installation standard and Queensland law. It is your proof that the gas work was done safely and legally.
If you are putting in a new gas cooktop, a gas hot water system, a bayonet for a BBQ, or having any gas line altered in Brisbane, the Gold Coast, Logan or Ipswich, this is the piece of paper you should walk away with. Here is what the certificate is, when the law says you need one, and how to get one.
What is a gas compliance certificate?
Its full name in Queensland is a gas system compliance certificate. It is the gas fitter’s formal statement that the work they carried out complies with AS/NZS 5601 (the gas installations standard) and the Petroleum and Gas (Production and Safety) Act 2004.
Some people call it a gas safety certificate. That is the same document. It records what work was done, who did it, and confirms the installation was tested and is safe to use. The certificate is lodged electronically through the Queensland gas work portal, so there is a formal record of it.
When do you legally need one in QLD?
Under the Petroleum and Gas (Production and Safety) Act 2004, a person who installs all or part of a gas system must give a compliance certificate for that work. You need one whenever new gas work or an alteration is done. That includes:
- Installing a new gas appliance (cooktop, oven, gas hot water unit, gas heater)
- Running a new gas line or adding a bayonet point for a BBQ or outdoor kitchen
- Altering, extending or relocating existing gas pipework
- Converting an appliance from natural gas to LPG or the reverse
The certificate covers the gas work itself. It is also the document a landlord, a buyer’s conveyancer, or an insurer may ask to see as evidence the gas installation was done properly by a licensed person.
| You need a certificate when | You generally do not for |
|---|---|
| Installing a new fixed gas appliance | Simply using an appliance already installed and certified |
| Adding or altering gas pipework | Buying a portable BBQ that connects to a bottle with a hose (no fixed gas work) |
| Adding a gas bayonet or connection point | Everyday maintenance that does not touch the gas system |
| Swapping an appliance that requires gas work |
If you are unsure whether your job needs a certificate, ask the gas fitter before the work starts.
Who can issue one?
Only a licensed gas fitter can issue a gas compliance certificate. Queensland runs a dual licence system, so a legitimate gas fitter holds both:
- A QBCC gasfitting licence (the contractor licence from the Queensland Building and Construction Commission), and
- An RSHQ gas work licence or authorisation (the occupational licence issued through the Chief Gas Examiner and Resources Safety and Health Queensland).
The gas fitter who did the work is the one who signs off the certificate. A neighbour, a handyman, or an unlicensed person cannot issue one, and gas work done by an unlicensed person carries penalties under the Act. Any gas fitter Call The Plumber Now sends to a job in Brisbane, the Gold Coast, Logan or Ipswich holds the licences the law requires.
What the certificate covers
The certificate confirms the gas work was installed and tested to AS/NZS 5601. In practice it records:
- The address and the gas work that was carried out
- The type of gas (natural gas or LPG)
- The licensed gas fitter’s details and licence
- Confirmation the system was pressure tested and is compliant
A note on compliance plates: from July 2025, most gas installations in Queensland no longer require a physical compliance plate fixed to the system. Caravans are the exception and still need one. The compliance certificate itself remains the key record for standard home and business installations.
How to get one (the process)
Getting a gas compliance certificate is not a separate errand you run. It comes with using a licensed gas fitter for the work. The steps look like this:
- You book a licensed gas fitter for the installation or alteration.
- The gas fitter carries out and pressure tests the work to AS/NZS 5601.
- On completion, the gas fitter must give you (the owner) the gas system compliance certificate straight away.
- Where the system is connected to a gas network, the gas fitter sends a copy to the network operator within 5 days.
- The certificate is lodged through the Queensland gas work portal, creating the official record.
Keep your copy somewhere safe. It is the document you produce later if a buyer, tenant, property manager or insurer asks for proof the gas work was done correctly.
What does a gas compliance certificate cost?
There is no fixed government price. The cost depends on the job, because the certificate is tied to the gas work itself rather than being a standalone fee. A single appliance install is different to running new pipework or a full changeover. The honest answer is to get a quote for your specific job so you know the full cost up front. For how gas work sits alongside other jobs, see our guide to what a plumber costs in Brisbane. Call The Plumber Now can quote gas work across Brisbane, the Gold Coast, Logan and Ipswich.
Gas compliance certificate vs water efficiency certificate
These two get mixed up, but they are different documents for different things. A gas compliance certificate is about the safety and legality of gas work. A water efficiency certificate relates to WELS-rated water fixtures (toilets, showerheads, taps) and, in Queensland, is tied to a landlord being able to pass full water consumption charges on to a tenant, provided the property has individual metering and water-efficient fixtures.
- Gas compliance certificate: gas installations, issued by a licensed gas fitter, required for the gas work.
- Water efficiency certificate: water fixtures and WELS ratings, connected to rental water charging, not gas safety.
If you need both, a licensed plumber and gas fitter can handle each on the one visit. They are not interchangeable, so make sure you ask for the right one.
