Do you need a licensed gas fitter? Victorian rules for gas appliance work

24 September 2026

Yes. In Victoria, all gasfitting work must be done by a licensed or registered gasfitter, with no carve-out for handy homeowners. That covers installing, converting, servicing or disconnecting any gas appliance: cooktops, ovens, heaters, hot water systems, and the bayonet point for the barbecue. Gasfitting is a specialised class of plumbing regulated by the Building and Plumbing Commission (BPC), the regulator that replaced the Victorian Building Authority in July 2025, with gas safety itself overseen by Energy Safe Victoria.

The rules are strict because the failure modes are: gas leaks, carbon monoxide, and in the worst cases fire or explosion. They also carry real teeth, with substantial fines for unlicensed work, and one consequence that stings even more in practice: unlicensed gas work can void your home insurance.

What is a gas fitter, and is a plumber also a gas fitter?

A gasfitter is a tradesperson licensed to work on consumer gas installations, meaning the pipework and appliances on your side of the meter. In Victoria, gasfitting is a registration class within plumbing, so many plumbers are also gasfitters, but not all of them, and certain jobs, like some appliance types and conversions, need additional endorsements on top.

The practical takeaway: before anyone touches gas in your home, ask whether gasfitting is on their licence, and check it with the BPC if you like; it takes a minute. Every gas job O’Shea Plumbing does is performed by licensed gasfitters, and has been since 1978. That’s not a boast so much as the minimum the work deserves. Our gas fitting page covers the full scope.

The jobs that need a licensed gasfitter

Everything that involves the gas itself:

• Installing or replacing a gas cooktop, oven or stove, including like-for-like swaps
• Installing, servicing or removing gas heaters, wall furnaces and ducted systems
• Gas hot water installation, replacement or disconnection
• Running or altering gas pipework, including BBQ bayonet points
• Converting appliances between natural gas and LPG
• Disconnecting and capping lines during renovations or appliance removal
• Investigating suspected leaks

So no, you can’t install a gas stove yourself in Victoria, even the same model in the same hole. The only parts of a gas appliance job a homeowner can legally do are the parts with no gas in them, which is roughly the unboxing.

One job deserves a special mention because demand has jumped as Melbourne homes electrify: gas wall heater removal. Taking out an old wall furnace means disconnecting and capping a live line, and usually making good the flue penetration. It’s a tidy half day for a licensed gasfitter, and our gas heating team does removals as readily as servicing.

What is a gas compliance certificate?

It’s the document your gasfitter lodges certifying the work meets the required standards. In Victoria, plumbers must issue a compliance certificate for work valued at $750 or more, and for certain gasfitting work regardless of value. Keep it with the house papers: it’s your evidence for insurance and for future buyers, and it means the work sits under the practitioner’s insurance and the regulator’s oversight. If a tradesperson goes vague when you ask about the certificate for gas work, that vagueness is your answer about the tradesperson.

And if you ever smell gas with no obvious source, isolate the meter valve, air the place out, and call. Our gas leak detection team carries equipment that finds what soapy water and noses miss.

The 2027 dates every gas household should know

Victoria’s building electrification rules bring two deadlines. From 1 January 2027, new homes and most new commercial buildings must be built all-electric. From 1 March 2027, a gas hot water system in an existing home that reaches the end of its life must be replaced with an efficient electric alternative, typically a heat pump. Repairs to existing gas systems stay legal, and gas cooking in existing homes isn’t touched.

Here’s what that means if your gas hot water is ageing: replacing it before 1 March 2027 is the last chance to choose gas again. After that date, its failure means going electric. Either path is licensed work, and because a heat pump changeover involves both plumbing and electrical trades, having both inside the one family group makes it a single coordinated booking with us rather than two companies and a gap between them. We’ll lay out both options with fixed pricing and let you decide; the barracking isn’t our department.
