Everything you need to know about hiring a gas plumber in Australia: services, costs, safety requirements, and how to verify gas fitter licensing.
A gas plumber (also called a gas fitter) is a specialised plumber licensed to work on gas lines, gas appliances, and gas systems in residential and commercial properties. In Australia, gas work is strictly regulated due to the serious safety risks involved — only plumbers with a current gas fitting licence or endorsement can legally perform gas-related work.
Gas plumbers handle a wide range of services including installing gas cooktops and ovens, connecting gas heaters, installing and repairing gas hot water systems, running new gas lines, performing gas leak detection and repair, and issuing gas compliance certificates. Whether you are building a new home, renovating your kitchen, or upgrading from electric to gas appliances, a qualified gas plumber is essential.
Gas plumber rates are typically 10-20% higher than standard plumbing rates due to the additional licensing, insurance, and safety requirements. Here is a comprehensive breakdown of gas plumbing costs in Australia for 2026:

Australia uses two types of gas in homes: natural gas (mains gas piped to your property) and LPG (liquefied petroleum gas, supplied in bottles). Understanding the difference is important when hiring a gas plumber and purchasing appliances.
If you are moving from an area with natural gas to one with LPG (or vice versa), your gas appliances will need to be converted by a licensed gas plumber. This typically costs $150-$300 per appliance. Never attempt to use a natural gas appliance on LPG or vice versa — this is extremely dangerous and can cause carbon monoxide poisoning or explosion.
Carbon monoxide (CO) is an odourless, colourless gas produced by incomplete combustion in gas appliances. It is the most dangerous risk from poorly maintained or incorrectly installed gas systems. CO poisoning causes over 50 hospitalisations and several deaths in Australia each year.
If you suspect carbon monoxide exposure, open all windows and doors, turn off gas appliances, evacuate the building, and call 000. Then contact a licensed gas plumber for an urgent inspection. Installing a carbon monoxide detector ($30-$80 from hardware stores) provides an additional safety layer for any home with gas appliances.

Gas plumber hourly rates in Australia range from $100 to $200 per hour during business hours, which is 10-20% higher than standard plumbing rates. After-hours gas plumber rates can be $200-$400 per hour. Most gas plumbers charge a minimum callout fee of $80-$150 plus their hourly rate.
No. In Australia, gas work can only be performed by a plumber who holds a specific gas fitting licence or endorsement in addition to their standard plumbing licence. A regular plumber without this additional qualification cannot legally install, repair, or maintain gas appliances or gas lines.
Installing a gas cooktop on an existing gas point costs $150-$350. If a new gas point needs to be run from the existing gas line, the cost increases to $400-$800 due to the additional pipework. Converting from electric to gas requires running a new gas line, which can cost $500-$1,000 depending on the distance from the nearest gas point.
A gas compliance certificate is a legal document issued by a licensed gas fitter after completing any gas work. It certifies that the work was done safely and meets all relevant Australian standards. You need one for every gas job, no matter how small. Your gas plumber must lodge the certificate with the relevant state authority. Keep your copies — you may need them when selling your property or for insurance claims.
Gas appliances should be professionally serviced by a licensed gas plumber at least every two years, though annual servicing is recommended, especially for gas heaters and hot water systems. Regular servicing ensures safe operation, maintains efficiency, extends the life of the appliance, and can identify gas leaks or carbon monoxide risks early.
