How much does gas installation cost?

$70 to $100 per hour

    How much does gas installation cost?

    Gas is often a cheaper energy alternative as compared to electricity. That is one of the main reasons why many Australians choose to have gas installed in their homes. The average cost of installation for gas service is between $1,200 to $5,000. 

    Gasfitters must be licenced to install gas services or repair gas lines because of the potential hazards involved. Labour is often one of the largest portions of the cost involved. Gas fitter rates are one of the more uniform labour markets in Australia. Here are some examples of what you could expect to pay in the different states.

    State Average installation cost per hour
    NSW $70 – $90
    VIC $70 – $90
    WA $90 – $110
    SA $70 – $90
    ACT $75 – $95


    Benefits of gas appliances

    Here are two of the main benefits of choosing gas appliances over electric ones:

    Cheaper than electricity 

    The main reason why Australians have gas appliances installed is the long-term cost of gas when compared to electricity. When you compare the gas utility cost to electricity, an electric clothes dryer will cost about 109c per hour, but an electric one will only cost about 60c per hour. An electric hot water tank will cost 396c per hour, while a gas one will cost about 240c per hour.

    More environmentally friendly than electricity

    Gas heat is considered to be more environmentally friendly than electricity. Gas is chemically simple and creates less pollution than coal-burning power plants. It produces lower levels of greenhouse gases, acid rain, and smog.

    Factors impacting the cost of gas installation

    Several factors affect the cost of installation of gas appliances. Understanding some of these factors can help you make a better decision about which is right for you. Here are some examples:

    Natural vs. LPG gas

    Natural gas connection cost is often cheaper than LP (liquid petroleum) gas. There is no tank to install and secure, and all that needs to be done is to establish a connection to the local supply line. If natural gas is not available in your area, then you will need to have an LPG bottle or tank installed, which is an extra cost. These tanks need to be replaced when they run out. LPG companies will either charge you when you need it replaced or you will pay an annual fee to cover this cost.

    How many outlets/gas appliances you want 

    The cost of installing a gas line depends on how many gas appliances you want to add. If you add just an oven, the cost will be less than if you convert the entire house to gas. If your home had gas appliances at some point, the gas line replacement cost might be lower if the old lines are still up to regulation and in good enough shape to use.

    House size

    The cost to get a gas line installed depends on the size of your house. For instance, if you have a two-storey house and need to supply hot water and heaters to the upstairs, it will cost more than for a small one-storey home. As a general rule, a bigger home size means more pipe to run. 

    The complexity of the job

    The cost to run a natural gas line from street to house depends on several factors. The slope of the land and distance will affect the cost. If the gas line must be installed under a sidewalk or driveway, it will add to the price. 

    Pipework materials

    Pipework materials significantly add to the gas line installation cost. Several components, including the natural gas connection and the cost of a gas metre, affect the total installation cost. The gas metre installation cost might be in addition to the cost for the gasfitter if the gas company itself must do it. 

    Professional’s level of expertise

    You can expect to pay more for a professional with many years of experience than for a newer gas fitter. One thing to consider is that while the professional might be higher in price when it comes to working with something like natural gas, the extra cost might be worth it.

    Price estimates for different types of gas installations and appliances

    Here are some typical costs for getting the most common gas appliances installed:

    Gas line installation

    Gas line installation costs between $1,200 for a simple job to upwards of $5,000 for a more complicated job. 

    Hot water system

    The average gas hot water heater cost can be anywhere from $750 to over $5,000, depending on the type of system that you get. 


    Gas heater installation cost can range from $3,000 on the low end to over $12,000 on the high end. The type of system that you choose, brand, and size of your home are the most important factors. 


    The average gas cooktop installation cost is about $290, not including the cost of the actual appliance. For a combo oven/cooktop unit or a single oven, gas oven installation costs around $390. The price of a gas oven is on average between $400 and $2,300.


    Gas fireplaces require a firebox, vent pipe and gas line. The total gas fireplace installation cost will depend on how many of these you need installed and is typically between $2,000 to $3,500.

    How to hire a gas fitter

    The decision to switch to gas appliances can be expensive in the beginning, but the long-term differences can represent considerable savings over time. Selecting the right professional is the first step to making sure that the job is done correctly and safely. Here are a few tips for choosing the right gas fitting specialist. 

    How to create an accurate estimate

    When you call for services, there are few things that you can do to help your professional create an accurate estimate. 

    • Have basic information ready, like the number of appliances that you will be installing
    • Know the size of your home and number of storeys, if you will be installing hot water in the upstairs 
    • Note any old gas lines that you have found in the home 

    Licencing and qualifications

    Only a licensed gasfitter can install or repair the gas system and its appliances. This is uniform nationwide across Australia. Some states might have stricter regulations, so be sure to check the qualifications that your professional must have before you hire. Here are a few questions to ask before you sign the contract. 

    • Do you meet all local licensing requirements on national, state, and local levels? 
    • Do you hold valid professional indemnity and public liability insurance? 
    • Do you provide written estimates? 
    • Do you provide a warranty or guarantee for your work?

    How to save money hiring a gas fitter

    Here are a few tips for saving some money when hiring a gas fitter. 

    • Get at least three estimates from only local, qualified professionals. 
    • Ask your professional if they can get any discounts on appliances. 
    • Shop and compare appliance prices online before you make a purchase.

    How much is a gas bottle?

    The price for a 45kg LP gas refill in New South Wales is about $132. In Queensland, the price for a 45kg bottle is around $149. Prices differ according to local demand and season.

    How much does natural gas cost a month?

    Downward Chevron
    The cost per month depends on how many appliances you have hooked to the system, your habits, and local prices. On average, you can expect to spend about a little under one-half as much with gas as you would pay for the same energy consumption using electricity. For instance, if your average electric hot water cost in Melbourne is $2,016, you can expect to spend around $1,276 for gas.

    Where should gas bottles be stored?

    Downward Chevron
    Be mindful of regulations on LPG gas bottle locations. All gas bottles should be stored in a cool, dry, well-ventilated area away from any sources of heat or flame; the space must be large enough to allow for adequate air circulation. The gas bottles should also be adequately secured by tie-downs or straps and be kept upright, as indicated by the safety instructions on the cylinders.
