Adding a new gas point, whether for an outdoor BBQ, a heater, or a kitchen appliance, is one of the more common jobs a licensed Gasfitter Melbourne homeowners call out for, and it is also one where the price can vary significantly from one property to the next. Gas point installation depends heavily on pipe length, access, and how much gas the new appliance actually needs, which is why two seemingly similar jobs can end up with quite different quotes. This guide covers what actually goes into a new gas point or gas line installation, what drives the cost, and what to expect from the process.
Prices below are general market estimates based on current Melbourne pricing guides and are not a quote from King and Sons Plumbing. Your exact price will depend on your property’s layout, existing gas infrastructure, and the appliance being connected.
How Much Does Installing a New Gas Point Cost?
A straightforward gas point installed close to an existing gas line, such as an outdoor BBQ point positioned near the meter or an existing branch line, generally falls in the low-to-mid hundreds of dollars. A gas point that requires a longer pipe run, more complex access, or connection to a higher-demand appliance climbs from there, often into the high hundreds or low thousands. If the property does not yet have a gas connection from the street main at all, there are two separate costs involved, the distributor’s connection fee to bring gas to your meter, and your gasfitter’s fee for running pipework from the meter to the new point, which together can run into the thousands depending on the scope of work. An accurate figure requires a gasfitter to assess your specific property and appliance.
Can an Existing Gas Line Be Extended?
Yes, in many cases extending an existing gas line to a new point is more straightforward and cost-effective than running an entirely new line from the meter. This depends on whether the existing line has sufficient capacity to also supply the new appliance without affecting the performance of appliances already connected to it. Your gasfitter will assess the existing pipework, its size, and the total gas demand of everything connected to it before confirming whether an extension is suitable or whether a separate new line is the better option.
How Far Can a New Gas Pipe Be Run?
There is no fixed maximum distance in the same way there might be for some electrical circuits, but practically speaking, longer runs require larger diameter pipe to maintain adequate gas pressure and flow at the appliance end. A gasfitter calculates the required pipe size based on the total length of the run, the number of bends and fittings involved, and the gas demand of the appliance being supplied, so a longer run is generally still achievable, it simply may require a larger pipe than a short, direct run would need.
Does Pipe Length Affect the Price?
Yes, significantly. Pipe length is one of the biggest cost factors in any gas line installation, since it directly affects the amount of pipe, fittings, and labour required. A short run to a nearby point costs considerably less than a long run across a property, particularly if that longer run needs to navigate around existing structures, through walls, under floors, or across a yard.
Does Pipe Diameter Matter?
Yes. Pipe diameter needs to match the gas demand of the appliance and the length of the run, since an undersized pipe cannot deliver enough gas volume to the appliance, particularly over a longer distance, which can result in poor appliance performance or an unsafe installation. Larger diameter pipe costs more in materials and is often more involved to install, particularly through tight access points, which is why appliance demand and pipe length together determine both the required pipe size and the overall cost.
Can a Gas Point Be Installed Outdoors?
Yes, outdoor gas points are one of the most common requests, typically for BBQs, outdoor kitchens, patio heaters, or fire features. Outdoor installations need to account for weatherproof fittings and appropriate protection for any exposed pipework, and the gasfitter will position the point to meet required clearances from windows, doors, and other structures as set out in the relevant gas installation standards.
Can You Install a Natural-Gas BBQ Point?
Yes, a natural gas BBQ point is a very common and generally straightforward installation, particularly if it is positioned reasonably close to an existing gas line. This gives you a permanent gas connection for your BBQ without needing to manage LPG bottles, and the point is typically fitted with a bayonet fitting allowing the BBQ’s hose to be quickly connected and disconnected as needed.
Can a Gas Bayonet Be Added for a Heater?
Yes, gas bayonet points are commonly installed for portable gas heaters, giving a safe, fixed connection point rather than relying on a bottled gas heater indoors. As with any new point, the gasfitter will confirm the existing line has sufficient capacity to supply the heater alongside any other connected appliances before installation.
Can Pipework Run Through the Ceiling?
Yes, running gas pipework through ceiling spaces is a common and generally practical method of reaching a new point, particularly in single-storey homes where the roof space provides straightforward access across the property. The suitability of this route depends on the specific layout of your home and the location of the new point relative to existing pipework and the roof space itself.
Can Gas Pipes Be Installed Underground?
Yes, underground gas pipe installation is common, particularly for outdoor points located away from the house or where running pipe through the building itself is impractical. Underground pipework needs to be installed at an appropriate depth and with suitable protection against damage, and this type of installation is generally more labour-intensive than an equivalent run through a roof space or wall cavity, which is reflected in the cost.
How Does the Gasfitter Determine Pipe Size?
Pipe sizing is calculated based on the total gas load of all appliances connected to that section of pipe, expressed in megajoules, combined with the length of the pipe run and the number of fittings and bends involved. This calculation follows the requirements set out in the relevant Australian gas installation standard, and it is not something that can be reliably estimated without knowing the specific appliance and the exact layout of the proposed pipe run, which is why an on-site assessment is generally necessary before a firm quote can be given.
Can the Existing Meter Supply Another Appliance?
Sometimes, and this depends on the total combined gas demand of everything already connected to your meter alongside the new appliance you want to add. If your existing meter and supply were sized for the appliances originally installed, adding a significant new load, such as an additional heater or a high-output cooktop, may exceed what the current meter and connection can safely supply. In this case, your gasfitter may need to liaise with your gas distributor about upgrading your meter or connection capacity before the new point can be safely installed.
Is Pressure Testing Required?
Yes. Once any new gas pipework and point are installed, the gasfitter is required to pressure-test the entire system to confirm there are no leaks and that gas is being delivered at the correct pressure throughout. This is a mandatory step for every gas installation, not an optional extra, and it is included as a standard part of the installation process and cost.
Is a Compliance Certificate Required?
Yes. The installation, modification, or relocation of consumer gas piping requires a compliance certificate in Victoria regardless of the cost of the job, which means even a small, single gas point installation is covered by this requirement. Your licensed gasfitter must issue this certificate and lodge it with the Building and Plumbing Commission, and you should receive your copy within a matter of days after the work is completed. This certificate is your record that the installation was carried out to the required standard, and it is worth keeping on file for future reference or if you sell the property.
