When winter arrives in Australia, keeping your home warm becomes a priority. Whether you're replacing an old heater, installing a new system, or upgrading to a more energy-efficient solution, one question often comes up:
Do you need a gas fitter or an electrician?
The answer depends on the type of heating system you're installing. Choosing the right licensed tradie not only ensures your heater works efficiently but also keeps your home safe and compliant with Australian regulations.
Here's how to know who you need for your heating upgrade.
If your new heating system runs on natural gas or LPG, you'll need a licensed gas fitter.
Gas fitters are qualified to install, repair, maintain, and test gas appliances and gas pipework safely. This includes ensuring there are no dangerous gas leaks and that all installations comply with Australian Standards.

Ignoring switchboard limitations can result in nuisance tripping, overheating circuits or reduced appliance performance.
Even if you're simply replacing an old gas heater with a similar model, you still need a licensed gas fitter.
They'll ensure:
Every gas appliance has specific installation requirements that should never be overlooked.
Some homeowners assume they only need one tradie, but many heating projects involve both.
Examples include:
These systems combine gas and electrical components, meaning each aspect must be installed by the appropriately licensed professional.
Hiring both trades from the beginning can prevent costly delays.
Heating upgrades aren't just about replacing old equipment—they're also an opportunity to reduce your energy bills.
Depending on your home, a qualified tradie may recommend:
The right recommendation depends on factors such as:

Heating systems involve potential hazards if they're installed incorrectly.

It's also worth arranging regular servicing to keep your heater operating safely and efficiently throughout winter.
Whether you need a gas fitter, electrician or both, finding experienced professionals is one of the most important parts of your heating upgrade.
Before hiring, consider:
Comparing multiple quotes can help you understand pricing, installation options and timelines before making your decision.
