What Gas Fitting and Appliance Installation Covers

Gas fitting and appliance installation covers connecting gas appliances to the supply, running the pipework and points that feed them, and certifying that the whole installation is safe and compliant. At the everyday end it is connecting a new gas cooktop or oven, fitting a bayonet point for a heater, or changing over a gas hot water unit. In the middle sit the heating installs that Victorian homes lean on, wall furnaces, space heaters and gas log fires, each needing the right flue and ventilation as well as the gas connection. At the larger end is whole-home ducted gas heating, a major install of a central unit, ducting and outlets. Running through all of it is the licensed gasfitter's core responsibility, which is not just to make the gas work but to make it safe, tested and certified, because gas is unforgiving of a job done loosely. A connection that merely looks finished can still leak or vent badly, which is why testing and certification are the real end of the job.

The defining feature of this trade is that it is licensed, and that is not a formality. Gasfitting in Victoria must be carried out by a registered gasfitter, and it is against the law for an unlicensed person to do gas work, because the risks, a leak, a fire, an explosion or carbon monoxide, are exactly the kind that licensing exists to prevent. Gasfitting is a class of plumbing work, so it sits alongside the wider plumbing services trade and the general gas fitting category, and many gasfitters also handle hot water and leak work. This page is the Victorian guide to the appliance side of it, what the work costs in 2026, what the law requires, and the safety every household should understand. The single most important rule is simple: gas work is never a DIY job. No saving is worth doing your own gas work, and the law reflects exactly how serious the risk is. A registered gasfitter brings the training and the testing equipment that make the work safe, which is precisely what an unlicensed attempt lacks.

Victoria's relationship with gas is unusually close, which shapes the demand. The state has long been the most gas-reliant in the country, with natural gas piped to most metropolitan homes and used heavily for heating through the cold Melbourne winters, as well as for cooking and hot water. Regional towns beyond the gas network run on LPG instead, delivered in bottles or tanks, which changes how appliances are set up. That deep reliance means a large installed base of gas appliances needing connection, replacement and servicing, even as the state begins a longer shift toward electric. For now, gas remains part of daily life in most Victorian homes, and keeping it safe is a constant need. Even as new homes go electric, the existing gas appliances in millions of rooms still have to be installed, serviced and replaced safely.

The sections ahead set out what each kind of gas appliance work costs in Victoria for 2026, the appliances a gasfitter installs, and the licensing and compliance that must come with the job. They also cover the carbon monoxide safety that makes heater servicing genuinely important, the difference between natural gas and LPG, the flue and ventilation that keep an appliance safe, and the evenhanded picture of gas versus electric as Victoria changes. The aim is that you understand what you are buying, why the certification matters, and how to recognise a gasfitter doing the job properly. The figures are Victorian and current for 2026, and the safety guidance follows the advice of the state's gas safety regulator. The intention is a guide you can act on, with the safety sections worth reading closely whatever appliance you have.

Appliances a Gasfitter Installs

Cooking appliances are the most common gas installs, and the most straightforward. A gas cooktop or an upright stove is connected to the gas point, tested for leaks, checked for correct flame and operation, and certified, which is usually a job of an hour or two, often dovetailing with the work covered under oven and cooktop installation. The appliance itself must be a certified gas appliance, and it has to be set up for the gas type in the home, natural gas or LPG, with the correct injectors. Even a simple cooktop swap is gasfitting work that needs a licensed gasfitter and a compliance certificate, not a job for a general handyman. The appliance looks like a plug-in until you remember the gas line behind it, which is precisely where the danger and the law both live. Getting a cooktop connected properly is quick, but it is still real gas work with real rules. The speed of the job is no reason to let an unlicensed person do it, since the rules apply to the smallest connection as much as the largest.

Heating is where Victorian gas work gets larger, and where the safety stakes rise. Gas space heaters and wall furnaces warm a room or a zone and need careful flueing and clearances so combustion gases vent safely outside, gas log fires bring the look of a fire with a flue to match, and ducted gas heating warms a whole home from a central unit through outlets in each room. These installs are more involved than a cooktop, taking in the appliance, the gas supply, the flue and the ventilation together, and the heater types tie into outdoor and gas heater installation and the fireplace work under chimney and fireplace services. Because a flued heater handles combustion gases, the quality of the install matters directly to the safety of the home. A wall furnace fitted with the flue and clearances right warms a home safely for decades, while the same unit fitted carelessly is a slow hazard. This is the part of gas work where cutting corners is genuinely dangerous. A heater that vents its combustion gases poorly is not an inconvenience but a threat to the people in the room.

Hot water and outdoor gas round out the common work. A gas hot water unit, whether a storage tank or a continuous-flow system, is connected and certified by a gasfitter, often as a like-for-like replacement when the old one fails, which overlaps with hot water system installation and the repair work under hot water system repairs. Outdoors, a gasfitter plumbs in a fixed barbecue, a patio heater or a gas pool heater, running a point to where it is needed. Each of these is a certified appliance on a certified connection, the same standard as indoor work. A barbecue plumbed into the gas line is held to the same rules as the cooktop in the kitchen, even though it lives outside. Whatever the appliance, the gasfitter's job is to connect it safely, test it, and certify it. The appliance changes from job to job, but that core duty of safe, tested, certified work never does.

Licensing and Compliance Certificates

The licence is the foundation of safe gas work, and it is worth understanding what it means. A gasfitter in Victoria holds registration or a licence as a plumbing practitioner in the gasfitting class, administered by the Building and Plumbing Commission, which means they have the training and the authority to carry out gas work legally. It is illegal for anyone without that registration to do gasfitting, and for good reason, because the consequences of an unqualified person working on a gas system can be fatal. Asking to see a gasfitter's registration is a reasonable and sensible step, and any genuine professional carries it. The licence is not red tape, it is the line between work that is safe and legal and work that is neither. Treating it as a formality to be skipped for a cheaper price is exactly how dangerous gas work gets into homes.

The compliance certificate is the other half, and it is your proof the work was done right. For prescribed gasfitting work, a registered gasfitter must issue a Compliance Certificate, which certifies that the installation meets the gas installation standard and has been tested, and it is lodged through the plumbing compliance system overseen by the Building and Plumbing Commission. This certificate is genuinely valuable to you as the homeowner, since it is evidence the work is compliant, it matters at sale time, and it carries a warranty on the plumbing work behind it. A gasfitter who does not provide a compliance certificate for work that requires one has not finished the job properly. Always expect the certificate, and keep it with your home's records. A buyer, a conveyancer or an insurer may ask for it later, and the gasfitter who issued it is your point of accountability. Filing the certificate with your other home papers takes a moment and can save real trouble years on.

The standard behind it all is the gas installation standard, and the appliances must be approved. Gas installation work in Victoria is carried out to AS/NZS 5601, the standard for gas installations, published by Standards Australia, which sets out how pipework, appliances, flues and ventilation must be done. The appliances themselves must be certified gas appliances approved for sale and use, not uncertified imports, which a reputable gasfitter will check. Together the licence, the standard, the certified appliance and the compliance certificate are what make a gas installation safe and lawful. None of these is optional, and a gasfitter who treats them as such is one to avoid. The licence, the standard, the certified appliance and the certificate are a set, and a gap in any one of them is a warning.

Carbon Monoxide and Gas Safety

Carbon monoxide is the gas-safety issue every Victorian household should understand, because it is invisible, odourless and can be deadly. When a gas heater burns its fuel incompletely or vents poorly, it can produce carbon monoxide, and a faulty or poorly maintained open-flued gas heater can spill that gas back into the room rather than safely outside. Carbon monoxide poisoning has caused deaths in Victoria, which is why the gas safety regulator, Energy Safe Victoria, runs ongoing awareness about it. The early symptoms, headaches, nausea and tiredness, are easily mistaken for other things, which is part of what makes it so dangerous. This is not a rare freak risk but a known hazard with a clear and manageable prevention. It is precisely because the prevention is so simple that an unserviced heater is such an avoidable danger. A two-yearly service is a small appointment that quietly removes one of the few genuinely deadly risks in a home.

Regular servicing is the prevention, and the advice is specific. Energy Safe Victoria recommends that open-flued gas heaters be serviced by a licensed gasfitter at least every two years, including a carbon monoxide test, to catch a heater that has begun to spill or burn incompletely before it becomes dangerous. A service checks the combustion, the flue and the seals, and a carbon monoxide test confirms the heater is venting safely, which is exactly the kind of small, regular job that prevents a tragedy. Older gas heaters, and open-flued ones in particular, are the ones to watch, and a heater that has not been serviced in years should be checked before another winter of use. Plenty of Victorian homes run a decades-old heater every winter without a thought, which is exactly the situation the servicing advice exists to address. The cost of a service is trivial against what it guards against. A service every couple of winters is one of the cheapest pieces of safety a gas home can buy. Set against the worst it prevents, it is hard to think of better-spent money.

A few sensible habits round out the protection. A carbon monoxide alarm, which is different from a smoke alarm, adds a layer of warning for homes with gas heaters, and ventilation should never be blocked off in a room with an open-flued appliance, since the appliance relies on it. If a gas heater shows soot marks, a yellow rather than blue flame, or a strange smell, or if people in the home get headaches when it runs, it should be turned off and checked by a gasfitter. None of this is cause for alarm in a well-maintained home, but it is knowledge worth having, because the people most at risk are usually those who did not know the risk existed. A serviced, well-flued gas heater is safe, and keeping it that way is straightforward. The danger lies almost entirely in neglect, which is reassuring, because neglect is the one thing entirely within your control to avoid.

Natural Gas, LPG and Conversions

The two kinds of gas behave differently, and an appliance is set up for one or the other. Natural gas is piped to the home through the mains network, which covers most of metropolitan Melbourne and many regional centres, and it is supplied at a lower pressure with a different burner setup. LPG, liquefied petroleum gas, is delivered in bottles or a tank and used where there is no mains gas, which is common in regional and rural Victoria, and it burns at a different pressure needing different injectors. An appliance built for natural gas will not run correctly or safely on LPG, or the reverse, without being converted. Knowing which gas your home runs on is the starting point for any appliance choice. It is the first question a gasfitter will ask, and the answer shapes everything from the injectors to the regulator. Getting it wrong is not a matter of performance but of safety, since an appliance on the wrong gas can burn dangerously.

Conversions are routine gasfitter work, but they must be done by the gasfitter, not improvised. Converting an appliance between natural gas and LPG means changing the injectors and adjusting the appliance to suit the new gas, a job for a licensed gasfitter who then tests and certifies the result, and many appliances come with a conversion kit for exactly this. It comes up when a home moves from LPG to newly available mains gas, or when an appliance bought for one gas type needs to suit the home's actual supply. Doing this properly is a safety matter, since an appliance running on the wrong gas can burn dangerously. A gasfitter handles the conversion as part of a correct, certified installation. It is straightforward in skilled hands and genuinely dangerous in unskilled ones, which is the pattern across all gas work.

The supply and the meter are part of the picture on a new connection. Where a home is being connected to mains gas for the first time, or a new appliance needs more gas than the existing supply can deliver, the gasfitter works with the gas line, the meter and sometimes the network to make sure there is enough capacity, and a larger appliance like ducted heating can need an upgraded supply. For an LPG home, the bottle or tank size and the regulator have to suit the appliances drawing on them. A single bottle that runs a cooktop may not keep up with a heater added later, so the supply is sized to the whole load. These supply details are easy to overlook until an appliance starves for gas, which is why a good gasfitter checks the supply can handle what is being added. Matching the supply to the appliances is part of a job done right. An appliance starved of gas runs poorly and unsafely, so the supply check is not an extra but part of the install itself.

Flues, Ventilation and Clearances

The flue is what makes a gas heater safe, and it is not an optional accessory. A flued gas appliance burns fuel and must vent the combustion gases safely outside through its flue, and an open-flued appliance draws air from the room and relies on that flue to carry the gases away, which is why the flue's condition and the room's ventilation matter so directly to safety. A blocked, damaged or poorly installed flue is exactly what leads a heater to spill carbon monoxide back into the home. Room-sealed or balanced-flue appliances draw their air from outside and vent outside in a sealed loop, which is inherently safer for the room, and a gasfitter advises on the right type for the situation. The flue is the safety system of a gas heater, not a detail to be rushed. More gas-safety incidents trace back to the flue and ventilation than to the appliance itself, which is why a good gasfitter dwells on them.

Ventilation and clearances go hand in hand with the flue. A gas appliance needs adequate ventilation to burn cleanly, which is why permanent vents in some rooms must never be sealed up, and it needs the right clearances from combustible materials and from windows and openings so it operates safely. These requirements are set out in the gas installation standard and are part of what a gasfitter checks and provides for, not guesswork. It is also why an appliance cannot simply be moved or boxed in without a gasfitter confirming the ventilation and clearances still work. Renovations that change a room around a gas appliance are a common way these requirements get accidentally broken. A gasfitter makes sure the appliance still has the air and the space it needs. A renovation that seals up a vent or boxes in a heater can quietly turn a safe appliance into a dangerous one.

Maintenance keeps the flue and the appliance doing their job over the years. Flues can corrode, come loose or get blocked by debris or nests, seals can perish, and an appliance's combustion can drift out of tune, all of which a service catches and corrects before they become a hazard. This is the practical reason behind the regular servicing of gas heaters, since the flue and ventilation are exactly what a service checks. An appliance installed perfectly still needs to be maintained to stay safe, particularly the older open-flued heaters. Treating the flue and ventilation as a living part of the appliance, rather than a one-time install, is how a gas home stays safe year after year. The install gets it right on day one, and the servicing keeps it right through every winter after.

Gas or Electric: The Victorian Shift

Victoria is in the middle of a long shift away from gas, and it is worth understanding evenhandedly. The state government has been encouraging a move toward electric appliances, with new homes increasingly required to be all-electric and a broader roadmap aimed at reducing gas use over time, information on which sits with the Victorian Government. The drivers are cost, emissions and the long-term direction of energy supply, and the electric alternatives have matured, with induction cooktops, heat-pump hot water and reverse-cycle air conditioning now doing the jobs gas traditionally did. None of this means existing gas appliances must be ripped out, and gas remains in most Victorian homes, but it does mean the gas-or-electric question is now a live one when an appliance reaches the end of its life. It is a genuine choice rather than a foregone conclusion in either direction. The right answer depends on your home and your priorities, not on a blanket rule, which is why it is worth thinking through properly.

When a gas appliance fails, the repair-or-replace decision now has a third option. Where once a failed gas heater or hot water unit was simply replaced with another gas one, many households now weigh switching to electric instead, since a reverse-cycle system through reverse-cycle air conditioning or a split system can replace gas heating, and a heat-pump hot water unit can replace a gas one. The case depends on the appliance, the home, running costs and any rebates available, so it is worth weighing rather than assuming either way. For cooling-led climates an electric system also covers summer, which a gas heater never did. A gasfitter or a broader trade can talk through what suits, and the honest answer varies from home to home. A household that wants summer cooling leans one way, while one happy with its gas heating and cooking may sensibly stay put for now. There is no single correct path, only the one that fits a particular home's needs, budget and plans.

Going electric still involves a gasfitter, which surprises some people. When a gas appliance is removed and not replaced, the gas point or line has to be safely disconnected and capped, or fully abolished back to the meter, which is licensed gasfitting work that must be certified just like an installation. Doing this properly matters, since a poorly capped gas line is a hazard left behind, and it is not a job to leave half-done or to a non-gasfitter. So even a home moving away from gas calls on a gasfitter to make the change safely. Whether you are installing, replacing or removing gas, the same licensed trade and the same certification apply. The gasfitter is part of the story at every stage, including the day you say goodbye to gas altogether.

What Drives Gas Fitting Pricing in Victoria

The appliance and its complexity set the base cost, and the range is wide. Connecting a cooktop or fitting a single gas point is a short, modest job, replacing a hot water unit or a space heater is a bigger one, and installing ducted gas heating or a gas log fire is a major install with the appliance, the gas supply, the flue and sometimes ducting all in play. The appliance itself is often supplied separately, so the quote may be for the installation alone or for supply and install, which is worth clarifying. The flue and ventilation work on a heater adds to the labour and materials. Two gas jobs described in a few words can sit far apart once the appliance and its flueing are counted. A cooktop connection and a ducted-heating install are both gas work, yet worlds apart in scope and price.

The gas supply and the access shape the rest. Running a new gas line or point to where an appliance is needed adds pipework and labour, and a long or awkward run, through a wall, under a floor or across a roof space, takes longer than a point near the meter. Whether the existing supply and meter can handle a new or larger appliance matters, since an upgrade adds cost, and an LPG home has its own supply considerations. The compliance certification is part of every job, included in the price of legitimate work rather than an optional extra. A gasfitter who quotes the appliance, the connection, the flue and the certificate separately makes it clear what each part is costing. That transparency also makes it obvious if a suspiciously low quote has left the flueing or the certification out. The lines that go missing from a cheap quote are almost always the ones that take time and protect you.

Geography and the type of work round out the picture across Victoria. Pricing is competitive across metropolitan Melbourne, where mains gas and plenty of gasfitters are the norm, while jobs in Geelong, Ballarat, Bendigo, the Latrobe Valley and Gippsland, Shepparton, Mildura, the Mornington Peninsula and the wider regions carry travel, and many regional homes are on LPG, which changes the setup. A major heating install is naturally dearer than a cooktop connection, and an emergency call-out through an emergency plumber for an urgent gas problem costs more than scheduled work. A suspected gas leak or a heater behaving strangely is one of the times paying for an urgent attendance is clearly worth it. The cheapest quote is no saving if it comes from someone unlicensed or skips the compliance certificate, because that is exactly the corner that makes gas work dangerous and unlawful.

Value in gas work is really about safety and legality as much as the appliance running. A correctly installed, certified gas appliance, connected by a registered gasfitter and backed by a compliance certificate, is safe, lawful and warranted, which is worth a great deal more than a cheaper job that lacks any of those. The money saved by using someone unlicensed or skipping the certificate is a false economy that can cost far more, in safety, in insurance, and at sale time. Set against the danger that bad gas work represents, paying for it done properly is not where to economise. Done right, gas work is the kind you never think about, because it simply works and stays safe. The cooktop lights, the heater warms, the hot water runs, and none of it gives you a moment's worry, which is exactly the point.

What to Look Out For

The first and most important check is registration, and it is non-negotiable. A legitimate gasfitter is registered or licensed as a plumbing practitioner in the gasfitting class, will happily show it, and will issue a compliance certificate for the work, while anyone offering to do gas work without a licence, or unwilling to provide a certificate, should be turned away on the spot. Be especially wary of a handyman or general tradesperson offering to connect a gas appliance to save you a gasfitter's fee, because that is unlicensed gas work and exactly the kind that causes harm. Asking to see registration is normal, and a genuine gasfitter expects it. There is no version of this job where an unlicensed person is an acceptable shortcut. On gas, the licence is not a preference but the bare minimum of doing the job at all.

On the quote and the work, the detail and the safety focus tell you a lot. A good gasfitter talks about the flue, the ventilation and the clearances, mentions the compliance certificate as a matter of course, and for a heater raises servicing and carbon monoxide rather than ignoring them. The quote should be clear on whether the appliance is supplied or just installed, what gas line or point work is included, and that the certificate is part of the price. A figure that seems low may be from someone unlicensed, or may leave out the flue work or the certification. Ask for registration, the certificate and the scope to be confirmed, because a professional gasfitter provides all three without hesitation. A reluctance to confirm any of the three is the clearest signal to look elsewhere.

How the safety side is handled separates the careful from the careless. A gasfitter who tests for leaks, checks the flue and ventilation, raises the servicing of an older heater, and is honest about whether a repair or a replacement, gas or electric, makes more sense, is one looking out for your home. Anyone who rushes a connection without testing, ignores a heater overdue for a service, or dismisses the carbon monoxide risk is one to avoid. The protections administered by Consumer Affairs Victoria sit behind the engagement, and the compliance certificate is your evidence the work met the standard. A gasfitter who treats safety as the point of the job, not an afterthought, is the one to keep. The best gasfitters talk about safety first and price second, because they understand which one actually matters with gas. A quote that opens with the certificate and the flue, rather than just a number, is usually a good sign.

How to Get Useful Quotes

A clear description gets you an accurate gas quote. Say what the appliance is and whether you are supplying it or want it supplied, where it is going and whether a gas point already reaches that spot, and whether the home is on natural gas or LPG, because each of those shapes the job. For a heater, note whether it is flued and where it vents, and for any older appliance mention if it is due for a service. A few photos of the appliance location, the gas meter and any existing point help a gasfitter scope it, and the suburb matters for travel and for whether you are on mains gas or LPG. The more a gasfitter knows up front, the tighter the quote and the smoother the visit.

For anything beyond a simple connection, a site visit makes the quote real. A gasfitter who sees the spot can check whether a gas point reaches it, whether the supply can handle the appliance, and what flue and ventilation are needed, where a number given off a description can move once the real layout appears. Use the visit to confirm registration, ask whether the compliance certificate is included, and raise servicing or the gas-versus-electric question if the appliance is at the end of its life. Ask each quote to state that the work is certified and the certificate provided, so you are comparing legitimate, like-for-like jobs. Comparing certified quotes from registered gasfitters is the only sound basis, since an unlicensed quote is no comparison at all. A cheaper number from someone who cannot legally do the work is not a saving, it is a liability.

Posting the job once on The Quote Yard reaches several registered Victorian gasfitters at the same time, rather than ringing around. Weigh the replies on the same points, the appliance and whether it is supplied, the gas line or point work, the flue and ventilation, the compliance certificate, and GST, so you are comparing like with like. A quote that comes in well under the others is worth questioning, since it may omit the flue work, the certification, or come from someone not properly licensed. The quote worth taking comes from a registered gasfitter, includes the certificate, and is clear on the appliance and the connection, and gathering a few of them costs nothing before you decide. With gas, the licence and the certificate matter as much as the price. A registered gasfitter and a compliance certificate are the two things you should never trade away for a lower quote.

Certification, Warranty and Australian Consumer Law

The compliance certificate is the document that matters most on gas work, so treat it as part of the deliverable. For prescribed gasfitting work, a registered gasfitter must provide a Compliance Certificate certifying the installation meets the standard and has been tested, and it carries a warranty on the plumbing work behind it, which is why it belongs in your home's records. It is evidence the work is safe and lawful, it matters when you sell, and it is what you rely on if a question ever arises about the installation. A gasfitter who completes prescribed work without issuing the certificate has not finished the job. Always expect it, and never accept gas work that comes without one where one is required.

Registration and insurance back the work beyond the certificate. A registered gasfitter carries the registration that makes the work legal and the insurance that stands behind any damage, which is part of what separates a professional from an unlicensed operator working cash-in-hand. The compliance certificate links the work to a registered practitioner and the standard it was built to, giving you a clear line of accountability. Using a registered gasfitter is not only safer but protects your home insurance, since a claim arising from unlicensed gas work can be a serious problem. The registration, the insurance and the certificate together are what make legitimate gas work worth its price.

Underneath it all sit the consumer guarantees, which apply to gas work as to any service. The work must be carried out with due care and skill and the appliance must be of acceptable quality, protections administered through Consumer Affairs Victoria and backed by the national framework overseen by the ACCC, while the gas safety side is regulated by Energy Safe Victoria. Where the gas work is part of wider plumbing or heating, it ties into gas fitting and leak repairs and the broader gas fitting service, so a whole job can be planned together. Choose a registered gasfitter who tests the work, provides the certificate, gets the flue and ventilation right, and is honest about servicing and the gas-or-electric choice, and the gas in your home stays the safe, quiet workhorse it should be.
