A gas compliance certificate is one of those documents that means nothing until the exact moment it does, at settlement, at a lease renewal, or when an insurer asks for proof that a gas job was actually done properly. It’s also one of the most misunderstood parts of getting gas work done, partly because the rules genuinely differ from state to state, and partly because the terminology shifts depending on who you ask. Any licensed Gasfitter Gold Coast homeowners call on should hand over one of these certificates as a matter of course after every job, not as an afterthought. This guide breaks down what a gas compliance certificate actually is, when you legally need one, and how the requirements differ across NSW, QLD, VIC, SA, and WA.
What Is a Gas Compliance Certificate?
A gas compliance certificate is a legal document issued by a licensed gas fitter confirming that gas work, an installation, alteration, extension, or repair, has been completed safely and tested in line with the relevant Australian Standards and your state’s regulations. It proves the work was carried out by a licensed professional, that the system has been checked for leaks and defects, and that it’s safe to use. Without one, there’s effectively no formal record that the gas work meets safety standards at all.
When Do I Need One?
A gas compliance certificate is required after essentially any gas work carried out on a network-connected or LPG gas installation, including:
- Installing a new gas appliance, such as a cooktop, oven, heater, or hot water system
- Replacing an existing appliance, even like-for-like
- Extending or altering gas pipework
- Installing a new gas point or bayonet
- Setting up a new LPG cylinder system
- Repairing a confirmed gas leak
Essentially, if a licensed gas fitter has touched your gas system, a certificate should follow. The only common exception is a standalone portable LPG BBQ connected via its own hose and regulator rather than a fixed gas point, since that setup generally sits outside the certificate requirement.
Who Issues It?
Only a licensed gas fitter can issue a gas compliance certificate, and in most states this requires more than a general gasfitting licence. In Queensland, for example, the fitter must hold a Gas Work Authorisation on top of their Gas Work Licence to legally issue one. If a tradesperson can’t produce or lodge a compliance certificate after gas work, that’s a clear sign to check their licensing before accepting the job as finished.
How Much Does One Cost?
For a standalone compliance certificate covering an existing gas system, pricing typically starts around $180 to $250 plus any inspection or service fees. When the certificate relates to new work, a cooktop installation, a hot water system replacement, or new pipework, the cost is usually bundled into the overall job price rather than charged as a separate line item, since testing and certification are simply part of completing that job properly.
Is It Required After Installing a Cooktop?
Yes, without exception, including a straightforward like-for-like swap. Every cooktop installation involves connecting to a live gas supply and needs to be pressure tested, both of which are exactly what the compliance certificate is verifying.
Is It Required After Replacing a Heater?
Yes. Gas heaters, whether flued, unflued, or bayonet-connected portable units, fall under the same certification requirement as any other gas appliance installation or replacement.
Is It Required After Gas Pipe Work?
Yes. Any alteration, extension, or repair to gas pipework requires a compliance certificate once the work is complete, since pipework changes directly affect the safety and integrity of the whole system, not just a single appliance.
Do I Need One When Selling My House?
This depends on your state, and it’s one of the areas where the rules genuinely diverge. In Queensland, there’s no separate mandatory point-of-sale gas certificate scheme the way there is for smoke alarms, but gas retailers commonly want a valid certificate on file before connecting supply for a new owner, so sellers without a recent one often arrange an inspection before listing to avoid delays at settlement. In other states, requirements and buyer expectations vary, so it’s worth checking with a local licensed gas fitter or your conveyancer well ahead of listing.
Do Landlords Need One?
In most cases, yes, and Victoria has a specific recurring requirement worth knowing about. Victorian rental providers must arrange a gas safety check every two years for eligible tenancy agreements, carried out by a licensed or registered gasfitter holding the relevant Type A gas appliances servicing endorsement. If a check has lapsed by the time a new tenant moves in, the rental provider is required to arrange one as soon as practicable rather than waiting for the next scheduled cycle. Other states don’t necessarily mirror this exact two-year cycle, but landlords everywhere carry a general duty to ensure gas installations remain safe for tenants, and a compliance certificate is the clearest way to demonstrate that.
What Happens If I Don’t Receive One?
Several real consequences follow. Your gas retailer can refuse to connect or continue supplying gas without valid compliance documentation on file. Home and landlord insurers commonly request the certificate as part of any gas-related claim, and can decline a claim without one. It can also complicate or delay a future property sale, since buyers and their gas retailer may request evidence the installation was done to standard. If a gas fitter completes work and doesn’t provide a certificate, that’s considered an offence in most states, and it’s worth contacting your state’s gas safety regulator, Resources Safety and Health Queensland, Building Commission NSW, or Energy Safe Victoria, depending on where you are, to report it.
Can I Get a Certificate for Old Work?
Generally, this requires an inspection by a currently licensed gas fitter, who will assess the existing installation against current standards and issue a certificate if it passes. If defects are found, you’ll typically be given a report outlining the issue along with a quote for the necessary repairs before a valid certificate can be issued. This is a common situation for older homes, properties changing hands without recent gas work, or systems where the original paperwork has simply been lost.
What If I Lose the Certificate?
In most states, digital certification systems introduced over the past couple of years mean your certificate is likely recorded centrally rather than existing only as a physical copy in a drawer. In Queensland, gas compliance is now managed through the RSHQ digital portal. In NSW, gasfitters submit certificates through the BCNSW eCert portal as of March 2026, replacing the older paper-based certification books and emailed PDFs entirely. If your certificate predates these digital systems and you can’t locate a copy, contact the gas fitter or company who completed the original work, or your state’s gas safety regulator, to check whether a record exists.
Are the Requirements Different in Each State?
Yes, meaningfully so. Here’s how the main states currently compare:
Queensland: Gas compliance is now fully digital through the RSHQ portal, introduced from February 2026. Compliance plates are no longer required for most residential installations as of July 2025, with the digital e-certificate serving as the legally binding record. Certificates for residential systems have no fixed expiry and remain valid until the system is altered or a new appliance is added.
New South Wales: As of March 2026, gasfitters must submit certificates of compliance and inspection through the BCNSW eCert portal. Older paper-based methods and emailed PDFs are no longer accepted, which means certification records now sit in a centralised digital system rather than relying on physical paperwork alone.
Victoria: Victoria doesn’t operate a standalone gas compliance certificate scheme in quite the same way as Queensland’s. Its recurring requirement is the rental gas safety check, on a two-year cycle for eligible tenancy agreements, along with a compliance certificate requirement for service and repair work totalling $750 or more.
South Australia and Western Australia: Both states require compliance documentation from a licensed gas fitter following installation, alteration, or repair work, administered through their respective state regulators. If you’re in either state, your licensed gas fitter can confirm the current process and documentation required for your specific job.
Because these systems continue to shift, digital portals, servicing endorsements, and threshold amounts have all changed within the past couple of years, it’s worth confirming the current requirement with a licensed local gas fitter rather than relying on general advice that may reflect an earlier system.
