Gas Fitting in Victoria: Licence Requirements Every Homeowner Should Know

Gas fitting is one of the most tightly regulated trades in Victoria, and for good reason. A poorly connected appliance or a leaking gas line is not just a maintenance problem, it is a genuine safety risk to your household. Gas leaks can cause fires, explosions, and carbon monoxide poisoning, and the consequences of a mistake are not reversible. That is why the law in Victoria draws a hard line: almost any work involving gas pipework or appliance connections must be carried out by a licensed gasfitter, full stop.

This guide explains what counts as gasfitting work, what licence a gasfitter needs, how to verify it, and why the Certificate of Compliance matters so much for your insurance and your property. It is written for homeowners across Melbourne, with particular attention to the older gas-connected homes common across the south-east.

Why gas fitting is strictly licensed in Victoria

There are three reasons the rules around gas work are so strict, and they reinforce each other.

Safety. Gas is invisible and, in the case of carbon monoxide, odourless. A connection that looks fine can leak slowly for months. Faulty flueing on a heater can push combustion gases back into living spaces. These hazards are not obvious to an untrained eye, which is exactly why the work is restricted to people who have been trained and assessed.

Insurance. Home and contents policies almost universally require that any gas work was performed by a licensed gasfitter. If a fire or incident is traced back to unlicensed gas work, the insurer can refuse the claim. You could be left covering the full cost of damage to your home yourself.

Legal liability. Under Victorian law, gasfitting must be done by a person holding the correct licence, and certain work must be certified. Doing gas work yourself, or paying someone unlicensed to do it, exposes you to legal liability if anything goes wrong, including liability for injury to others.

What counts as gasfitting work

The category is broader than most homeowners expect. Gasfitting in Victoria covers, among other things:

• Appliance connections. Connecting a gas cooktop, oven, heater, hot water unit, or outdoor BBQ point to the gas supply.
• New gas lines. Running new pipework to add a gas point or extend supply to a new appliance location.
• Repairs to gas pipework. Fixing leaks, replacing damaged sections of gas pipe, or altering existing runs.
• Compliance certification. Issuing the Certificate of Compliance that confirms the work meets the relevant standards.

If the job touches gas pipework or a gas connection in any way, it is gasfitting and it needs a licensed gasfitter. Swapping a freestanding electric oven is not gas work. Swapping a gas cooktop is.

Licence types in Victoria: the Type B gasfitting licence

For residential work, the licence that matters is the gasfitting licence issued through the Victorian Building Authority (VBA) framework, commonly held alongside a plumbing licence. The standard residential gasfitting class, often referred to as Type B gasfitting, covers the everyday work most homeowners need: connecting and servicing domestic gas appliances, installing and altering consumer gas piping, and issuing compliance certificates for that work.

A genuinely licensed gasfitter has been trained, assessed, and registered to do this work. The good news for homeowners is that you do not have to take anyone's word for it. You can verify a licence yourself in a couple of minutes.

Go to the VBA's check tool at https://www.vba.vic.gov.au/check-licence-registration, enter the gasfitter's name or licence number, and confirm that they hold a current gasfitting licence or registration. It is worth doing before any gas work begins. A reputable gasfitter will not mind at all, and gasfitters in our network are all VBA-licensed and happy to provide their details.

What work homeowners can legally do themselves

This is the simplest section in the guide, because the line is clear. When it comes to gas, a homeowner cannot legally do work that involves gas pipework or gas connections. There is no minor exception, no small job you are allowed to handle yourself.

That means you cannot connect your own cooktop, run your own gas line, repair a gas leak, or reconnect an appliance after a renovation. All of it requires a licensed gasfitter.

What you can do is the non-gas side of preparing for the work: clearing access to the appliance area, choosing the appliance, arranging the cabinetry or bench cut-outs for a new cooktop, and being home to let the gasfitter in. The actual gas connection is theirs to make, and theirs to certify.

The Certificate of Compliance

A Certificate of Compliance is the document a licensed gasfitter issues to certify that the gas work they performed meets the required Victorian standards. It is your proof that the job was done correctly by someone authorised to do it.

Compliance certification is required for most gasfitting work beyond the most trivial servicing. You should expect one for a new appliance connection, a new or extended gas line, or any repair to gas pipework. The gasfitter lodges the certificate, and you receive a copy.

Why it matters to you specifically:

• Insurance. If you ever need to make a claim involving gas, the certificate is your evidence that the work was compliant and licensed. Without it, an insurer has grounds to question the work.
• Property sale. When you sell, gas work that lacks compliance documentation can become a sticking point during conveyancing and building inspections. Keeping certificates on file protects the value and saleability of your home.
• Peace of mind. It confirms the work was independently certified against the standards, not just done and hoped for.

Keep every Certificate of Compliance you receive with your property records. They are easy to file and genuinely valuable later.

What happens if unlicensed gas work is discovered

The consequences of unlicensed gas work fall on the homeowner, which surprises a lot of people. Here is how it typically plays out.

Insurance voidance. If an incident occurs and the insurer finds the gas work was unlicensed or uncertified, they can decline the claim. A fire that should have been covered becomes a cost you carry alone.

Rectification cost falls on you. If unlicensed work is found, whether during a sale, an inspection, or after a problem, it usually has to be torn out and redone correctly by a licensed gasfitter. You pay for that rectification, on top of whatever you paid the first time.

Legal liability. Beyond money, there is liability. If unsafe gas work injures someone in your home or a future occupant, the responsibility can land on you. No saving on the original job is worth that exposure.

The pattern is consistent: unlicensed gas work shifts risk and cost onto the homeowner. Using a licensed gasfitter and keeping the compliance certificate is the only way to stay protected.

Converting from gas to electric

The policy direction in Victoria has shifted clearly towards electrification. New homes and renovations are increasingly being built without gas, and there is growing support for households moving away from gas appliances towards electric alternatives such as induction cooktops, reverse-cycle heating, and heat-pump hot water.

Practically, for an existing homeowner, a switch to electric means a few things. Removing or capping a gas supply still involves gas work, so a licensed gasfitter is needed to disconnect and make safe any gas pipework, even when the end goal is to have no gas at all. New electrical circuits for high-draw appliances like induction cooktops or heat-pump systems are a job for a licensed electrician. The two trades often coordinate on the same project.

If you are weighing up a switch, it is worth getting a licensed gasfitter to assess your current setup so you understand what is involved in safely decommissioning the gas side. The plumber we connect you with can advise on capping and making safe the gas supply as part of that process.

South-east Melbourne context

Gas connections are very common across the south-east, particularly in the wave of homes built from the 1970s through the 1990s in suburbs like Casey, Kingston, and Frankston. Many of these homes were built with gas cooktops, gas wall furnaces or ducted gas heating, and gas hot water as standard.

That housing era brings a few practical realities. Appliances installed decades ago are now well past their service life and are frequently being replaced, which means new appliance connections are one of the most common gasfitting jobs in the region. Older gas pipework may need inspection or upgrade when appliances change. And homeowners considering electrification are most often found in exactly these established gas-connected suburbs.

Whatever the job, the rule is the same across every suburb: gas work needs a licensed gasfitter and, in most cases, a Certificate of Compliance. See the gas fitting service page for more on what a typical job involves.
