If you’ve had gas work done at your property, there’s a good chance you’ve heard the term gas compliance certificate.
A gas compliance certificate is an important document that confirms gas installation or repair work has been completed safely and meets legal standards.
Whether you’re installing a new cooktop, replacing a gas hot water system, or extending gas lines, understanding how this works can save you from future safety issues, delays, and legal problems.
Here’s what you need to know.
A gas compliance certificate is a document issued by a licensed gas fitter after completing certain gas work.
It confirms that the installation, repair, or modification has been carried out according to Australian Standards and Victorian safety regulations.
In simple terms, it means the work has been checked and declared safe.
This certificate is often required for:
Without it, there may be no proof that the gas work was completed correctly.
Yes, in many cases.
In Victoria, a licensed gas fitter must issue a Certificate of Compliance (CoC) for gas work valued at more than $750, including labour and materials.
This applies to many common household jobs, such as:
Even for smaller jobs under this amount, the work still needs to comply with safety standards. The certificate acts as formal proof that the installation meets Victorian regulations.
A gas compliance certificate is usually needed whenever gas systems are installed, altered, or upgraded.
Some of the most common situations include:
If you’re adding a new gas appliance like a cooktop, oven, or heater, the installation needs to be tested and certified.
This includes checking gas pressure, ventilation, and leak safety.

Swapping out an old unit for a new one often requires compliance, especially if pipework or fittings are changed.
This is one of the most common jobs Melbourne homeowners need certification for.
If you’re adding a BBQ connection, outdoor kitchen, or new gas bayonet point, new gas pipework must be installed correctly and certified.
Kitchen and laundry renovations often involve moving or upgrading gas appliances. Any changes to gas systems may require a compliance certificate.

Only a licensed gas fitter can issue a gas compliance certificate.
This is important.
Not all plumbers are licensed gas fitters. If the person doing the work does not hold the correct gas licence, they cannot legally certify it.
Always check that your plumber is properly licensed for gas work in Victoria.
This protects you if problems show up later.
A compliance certificate is not just a signature. It confirms the gas fitter has tested and checked the system properly.
This can include:
These checks help reduce the risk of gas leaks, poor combustion, and carbon monoxide issues.
Skipping a gas compliance certificate can create problems later.
This may include:
A gas compliance certificate does not expire. It applies to the specific work completed at that time.
Think of it as a permanent record showing the installation was compliant on the day it was finished.
That said, gas appliances still need ongoing maintenance and servicing over time. A certificate does not replace regular inspections.
In many cases, no. Gas suppliers may require proof that the installation is safe before connecting supply.
Not always. In Victoria, it usually applies to work over $750, but all gas work must still meet safety regulations.
Not exactly. A compliance certificate confirms completed work is compliant. A safety inspection checks an existing system for faults.
You should receive a copy from your gas fitter and keep it for your records.
A gas compliance certificate is one of the most important parts of any gas installation. It confirms the work has been completed safely, legally, and to the required standard.
