In Queensland, a Gas Compliance Certificate for a business or commercial property usually starts at about $180.
Any time a new gas appliance or gas system is installed in Queensland, a Gas Compliance Certificate is required to show the work has been completed safely and correctly.
In this guide, we explain how much a gas compliance certificate costs, what it is, and why it is important.
How Much Does A Gas Compliance Certificate Cost?
The cost can vary depending on the type of appliance and the complexity of the installation. As a general guide:
- Standard appliance installation with certification: From $250, plus any applicable service call fee
- Stand-alone certificate for an existing gas system: From $180, plus any applicable service call fee
- Multiple appliances or complex installations: Pricing is provided upon assessment and quoted accordingly
What Is A Gas Compliance Certificate?
A Gas Compliance Certificate is an official document that shows gas work was done by a licensed gas fitter/plumber and meets the AS/NZS 5601 safety rules.
It is required when work is done on gas appliances, such as:
- Installing a new gas stove, oven, or BBQ
- Installing or replacing a gas hot water system
- Adding or extending gas pipes or connections
- Converting to LPG or upgrading a gas regulator
- Moving or disconnecting a gas appliance
If you do not have this certificate, your insurance or warranty may not cover problems related to gas in the future.

Who Provides Gas Compliance Certificates?
Gas compliance certificates can only be issued by a licensed gas fitter/plumber who is qualified to carry out gas work.
After completing any gas installation, modification, or extension to an existing gas system, the gas fitter will issue a Gas Compliance Certificate to confirm the work meets safety standards and regulations.
In most cases, the certificate is provided within 30 days of the work being completed.
Why Should I Get A Gas Compliance Certificate?
Keeping your gas compliance certificate up to date is an important way to make sure your home or business stays safe. There are several key reasons why having one matters:
- Safety: A valid gas compliance certificate shows that your gas appliances and gas system have been checked and are working safely.
- Future support: If a problem happens later with a gas appliance, the licensed gas fitter who completed the inspection can often identify and fix the issue quickly.
- Insurance protection: If your gas system does not meet current Queensland safety standards, or it has not been checked by a licensed gas fitter, your insurance company may refuse a claim if something goes wrong.
What Is The Difference Between A Gas Compliance Certificate, Gas Inspection Certificate And Gas System Compliance Plates?
Gas Compliance Certificates
A Gas Compliance Certificate is a document written by a licensed gas fitter and given to the homeowner/business owner.
It confirms that gas appliances and systems have been connected to the gas supply safely. The certificate applies to both natural gas and LPG systems.
Gas Inspection Certificates
A gas inspection certificate is very similar to a gas compliance certificate.
This type of certificate is usually used for gas systems that are not connected to the main gas network, such as in caravans, boats, or homes in rural areas that use gas bottles.
Gas System Compliance Plates
A gas system compliance plate is a small label that shows the gas installation was done safely.
It lets people quickly see that the work meets industry safety standards and was completed by a licensed professional.
When You’ll Need A New Gas Certificate
You will need a gas compliance certificate when:
- Installing or replacing a gas stove, cooktop, or oven
- Installing a gas hot water system
- Installing or changing gas pipes or connections
- Carrying out annual gas safety checks
Each certificate confirms that the work is safe, properly recorded, and meets Queensland safety rules.

Compliance Requirements Vary By State
Some states require a metal compliance plate or badge to be attached near the place where the gas work was completed. This plate shows that the installation was done safely and follows the rules.
If your state requires a plate or badge, your licensed gas fitter/plumber will supply and install it.
Here is a simple guide to the requirements in each state:
- Queensland: Certificate of Compliance
- New South Wales: Compliance plate near the installation or a Certificate of Inspection/Compliance
- ACT: Compliance plate near the installation
- Victoria: Certificate of Compliance
- South Australia: Certificate of Compliance
- Tasmania: LP Gas Storage Notice (Start Work Notice)
- Western Australia: Notice of Completion (NOC) and a Compliance Badge
- Northern Territory: Compliance plate near the installation
These rules can be confusing because each state has slightly different requirements. When you contact us to organise your gas delivery, we will explain the process and help make sure everything is set up correctly so you can safely enjoy your new home or gas appliances.
What Is A Gas Defect Notice?
A gas defect notice may be issued by a qualified gas fitter/plumber if they believe your gas system is unsafe or does not meet Queensland safety rules.
This notice is given when there is a serious problem that could lead to a gas leak or other danger if it is not fixed quickly.
