Safe, Certified Gas Fitting for Adelaide Homes
Every gas job needs a licensed hand, and Simms Plumbing & Air Conditioning brings Cert IV gasfitting, upfront fixed pricing, interest-free finance and a lifetime labour warranty to each one.
Gas is convenient but unforgiving when it is installed badly. Our licensed gas fitters handle installations, repairs and appliance work across Adelaide, always to AS/NZS 5601, so your home stays safe, efficient and fully compliant.
The Gas Fitting Work We Take Care Of
Our licensed gas fitters cover every kind of gas work for homes across Adelaide:
-
Gas Appliance Installation
From cooktops to heaters and outdoor burners, we connect new gas appliances correctly, test them for leaks, and make sure each one runs safely before we hand it back over.
-
Gas Cooktops and Ovens
Whether you are upgrading the kitchen or replacing an old unit, we install gas cooktops and ovens to the right clearances, connect them safely, and check every burner lights cleanly.
-
Gas Heater Installation and Service
We install and service gas heaters, ducted systems and space heaters, checking the flue and combustion so they warm your home efficiently without any risk of carbon monoxide building indoors.
-
Gas Hot Water Connections
When you choose a gas hot water system, we run the gas supply, connect and commission the unit, and make sure your hot water runs safely from the first day.
-
New Gas Lines and Extensions
Adding a gas point for a new appliance, extending a line or relocating one, we size and run the pipework correctly so every outlet gets safe, reliable pressure where needed.
-
Gas Leak Detection and Repair
If you suspect a leak, our gas fitters trace it, make the area safe, and repair the fault fast; for after-hours leaks our emergency plumbers are on call as well.
-
LPG and Natural Gas Work
We work with both natural gas and LPG, converting appliances between the two, swapping regulators and fittings, and making sure the changeover is done correctly and certified as fully compliant.
Why Professional Gas Fitting Matters
Gas is not a job for shortcuts, which is why every Simms gas fitter works strictly to standard:
-
Your Family's Safety
Badly fitted gas can leak or produce carbon monoxide, which is colourless and odourless, so correct installation and testing by a licensed gas fitter protects everyone living in the home.
-
Done Right the First Time
Gas work done badly often has to be redone, sometimes after a dangerous fault, so getting a qualified gas fitter in from the start saves money, stress and risk later.
-
Efficient, Reliable Gas
A correctly sized and tuned gas system burns cleanly and uses less gas, so professional fitting does not just keep you safe, it keeps your energy bills down over time.
-
Compliance That Protects You
Unlicensed gas work can void your home insurance and breaches South Australian law, so always use a licensed gas fitter; it protects you legally, financially and physically all at once.

Common Gas Problems We Sort Out
A handful of gas faults make up most of our call-outs across the southern suburbs:
-
Suspected Gas Leaks
If you smell gas, leave and call the gas emergency line first; the network makes the area safe, then we find and repair the leaking pipe, fitting or appliance properly.
-
Pilot Lights and Ignition Faults
When a heater or hot water pilot will not stay lit, or a burner will not ignite, we clean or replace the faulty part and get the appliance firing again.
-
Carbon Monoxide Concerns
Carbon monoxide from a faulty gas heater is dangerous and hard to detect, so we test the appliance, inspect the flue and combustion, and shut down anything that seems unsafe.
-
Old or Non-Compliant Installations
Older gas work sometimes fails to meet current standards, so when we find unsafe pipework or fittings during a job, we explain the issue and bring it up to code.
Gas Fitting for Every Type of Property
We do gas work at all kinds of properties throughout southern Adelaide:
-
Older and Established Homes
Many older southern suburbs homes have ageing gas lines and original appliances, so we upgrade and certify them safely, replacing anything that no longer meets the current gas safety standards.
-
New Builds and Renovations
On new builds and renovations we plan and run the gas to suit the kitchen, heating and hot water, coordinating with other trades so the whole job passes compliance cleanly.
-
Rental Properties
Landlords have clear gas safety duties, so we carry out compliant installations and safety checks, then provide the documentation and invoicing that agents and owners need for their own records.
-
Cafes and Small Businesses
Commercial kitchens and businesses rely on gas every day, so we install and service commercial appliances, keep you compliant, and work around your hours to limit any downtime for trade.
Licensed, Certified Gas Work You Can Trust

- Certificate IV in Plumbing and Gas, so all gas work is carried out by a fully qualified, licensed gas fitter.

Frequently Asked Questions About Gas Fitting
Here are the gas questions Adelaide homeowners ask us most:
Do I need a licensed gas fitter in Adelaide for gas work?
Yes. In South Australia, by law, gas work must be carried out by a licensed gas fitter, which is what our team holds, so the job is legal and safe.
Do you install and service gas heaters?
Yes. We install, service and repair gas heaters, ducted systems and space heaters, checking the flue and combustion so they run safely and efficiently through winter.
Can you convert my appliance from natural gas to LPG?
Yes. We convert many cooktops, ovens and heaters between natural gas and LPG by changing injectors and regulators, then test and certify the appliance runs safely afterwards.
How do I know if I have a gas leak?
Common signs are a rotten-egg smell, hissing near pipes, a pilot that keeps going out, or higher gas bills. If you smell gas, leave and call the emergency line.
Are your gas fitters fully licensed and insured?
Yes. Simms Plumbing & Air Conditioning holds a Certificate IV in Plumbing and Gas plus full insurance, so every gas job is legal, safe and properly certified.
How much does gas fitting cost?
It depends on the job, from a simple appliance connection to a full installation. We give you a fixed price upfront after assessing the work, so you are never surprised.
