Gas Appliance Service near you

Gas safety in Australia is administered state by state, with a national technical standard underneath. Each jurisdiction licenses the people who may carry out gasfitting work and runs its own compliance regime: in Victoria, plumbers and gasfitters are registered and licensed by the Building and Plumbing Commission while Energy Safe Victoria regulates gas safety, and in Western Australia gasfitting work sits under the Gas Standards (Gasfitting and Consumer Gas Installations) Regulations 1999, administered by Building and Energy. Before a booking, it is reasonable to ask for the licence number and check it on the relevant regulator's public register.

The technical rules come from AS/NZS 5601, the gas installations standard. Western Australia's regulator records that AS/NZS 5601.1:2022 was published on 30 September 2022, is automatically adopted in that state, and that gasfitters were required to comply with it in full from 30 March 2023. It also records a point that matters when you are weighing a repair against a replacement: the 2022 edition applies to new installations and to modifications or extensions of existing installations, and does not apply retrospectively to existing gas installations or their repair. Other states and territories call up the same standard through their own gas legislation.

What this means for a homeowner is simple enough. Servicing and repairing your existing heater is done to the standard the installation was built to, but moving it, replacing it, extending the pipework or adding an appliance brings the current edition into play, along with its clearance and ventilation requirements. A gasfitter who raises that on a replacement quote is doing the job properly, not padding it.

Energy Safe Victoria sets out why servicing matters in terms of what actually goes wrong inside these appliances: burners in water heaters or space heaters can become blocked with dust or lint and then soot up the heat exchanger and flue passageways; air filters, air ways and fans can become blocked by lint and dust, leading to overheating and burner problems; and safety controls can wear out and fail. Any of these can increase the risk of the appliance spilling carbon monoxide, which is why a service is a combustion check rather than a clean.

One requirement is worth knowing before you compare quotes. ESV states that as part of a comprehensive service, a gasfitter must use a carbon monoxide analyser to test for carbon monoxide spillage, and advises using a registered or licensed gasfitter who has completed the recognised carbon monoxide training course. A visit that involves no analyser is not a comprehensive service, whatever it is called on the invoice.

Ask for the result in writing. ESV's advice is to ask for a service report and keep a record of the date of service, and that record is what tells the next gasfitter — or a buyer's inspector — what was found and when. Keep it with the appliance manuals rather than in a drawer with the receipts.

For heating appliances, Victoria's regulators give a clear interval: Energy Safe Victoria and the Building and Plumbing Commission recommend that all gas water heaters, space heaters and central heaters are serviced once every two years by a qualified gasfitter to ensure they are working properly. ESV's guidance on negative pressure repeats the two-year interval for heaters and adds that the service should include a check for negative pressure by the gas plumber. Manufacturers sometimes specify a shorter interval, and where they do, theirs governs.

Cooking appliances sit on a different footing, because a cooktop is flueless and is used in short bursts with the kitchen exhaust running. They still need attention — clean burner ports, correct clearances and adequate ventilation — but the regular servicing recommendation is aimed at water heaters, space heaters and central heaters. If your only gas appliance is a cooktop, the useful habits are keeping the burners clean, running the rangehood, and calling a gasfitter the moment the flame colour changes.

Carbon monoxide is a poisonous, colourless and odourless gas that interferes with the blood's ability to carry oxygen. Energy Safe Victoria's information sheet on domestic carbon monoxide alarms notes that under normal operating conditions, well maintained and correctly ventilated gas appliances produce minimal carbon monoxide, and that high levels can occur where an appliance is not installed in an adequately ventilated area, where there is excessive spillage or reverse flueing, where several gas appliances run at once without additional ventilation, or where a flueless appliance is operated for extended periods.

A carbon monoxide alarm is worth having, but it is not a substitute for a service, and ESV says so directly: alarms can be a useful back-up precaution but should not be considered a substitute for the proper installation and regular maintenance of gas appliances, every two years. ESV's placement guidance is to make sure the alarm is audible from all sleeping areas, to install alarms in or near rooms with gas heating appliances and in or near bedrooms, and to keep them away from the immediate vicinity of a gas cooking appliance, where they may nuisance-trip.

The other half of the picture is what else the house is doing while the appliance runs. Exhaust fans and rangehoods can create negative pressure that draws dangerous gases, including carbon monoxide, into living areas through a flue or chimney, which is why ESV advises against running exhaust fans at the same time as an open-flued heater and asks that the negative pressure check form part of the heater's service.

Gas appliances sold and installed in Australia are certified before they get anywhere near a house, and the certification is something a gasfitter has to verify. Energy Safe Victoria's guidance for the trade states that a licensed gasfitter may only install a Type A gas appliance if there is documented proof of Australian certification, or the appliance carries a certification badge from an authorised acceptance scheme. Those badges — stickers or plates — are issued by bodies including the Australian Gas Association, SAI Global, the International Association of Plumbing and Mechanical Officials, Global-Mark, Vipac, BSI Group and Energy Safe Victoria itself. These are certification bodies operating under authorised schemes rather than government regulators, and the Australian Gas Association is an industry association that also performs certification.

There is a central place to check. ESV points to the Gas Technical Regulators Committee national certification database as a source of information about appliance certification, and says that if an appliance is listed as certified, a licensed gasfitter may install it. Where certification cannot be established — most often with a one-off or imported appliance — the appliance should be replaced with an Australian certified one, or an application made under the relevant acceptance scheme or to the state regulator.

The consumer lesson is short. A second-hand heater bought online, an appliance carried over from overseas, or a caravan unit repurposed indoors may not be certified for use here, and a licensed gasfitter is not permitted to install it. Ask about certification before money changes hands, not after the gasfitter declines the job.

Gas emergencies are not maintenance problems and should not wait for a booked service. If you can smell gas, get people out of the affected area and ventilate it, do not go hunting for the source, and call the emergency number printed on your gas bill — the distributors staff those lines at any hour. For LP gas, the supplier's emergency contact is usually shown on the cylinder or tank. Energy Safe Victoria's advice is to turn the gas off at the meter for natural gas, or at the tank or cylinder for LP gas, only if it is safe to do so.

If anyone in the house has symptoms consistent with carbon monoxide exposure, or an alarm has sounded, the order is people first: out into fresh air, then medical advice, then the appliance turned off and left off until a licensed gasfitter has tested it with an analyser. An appliance that has spilled once will spill again, and the fact that it seems to run normally afterwards proves nothing at all.

Gas servicing is a service under the Australian Consumer Law, and the guarantees that come with it are automatic. The ACCC states that service providers must carry out all services using an acceptable level of care and skill, that services and any resulting products must be fit for any stated purpose, and that services must be supplied within a reasonable time where no time frame has been agreed. Those guarantees apply alongside the licensing obligations, not instead of them.

Where the appliance itself is at fault rather than the workmanship, the product guarantees apply: for a major problem the business must give the consumer the choice of a refund or a replacement of the same type, and for a minor problem it must fix the problem or repair the product for free. Keep the service report, the invoice and the licence details of whoever did the work. If you believe unlicensed gas work has been carried out at your property, the state gas safety regulator — not the platform you found the tradesperson on — is the body to tell.
