Quick answer: can a plumber do gas work in Sydney?
A plumber can only carry out gas work in NSW if they hold a separate gasfitting licence — plumbing, draining and gasfitting are distinct licence categories, and unlicensed gasfitting is illegal regardless of the size of the job. So before anyone touches your cooktop, heater or gas hot water unit, ask for their NSW gasfitting licence number. Rectify Plumbing holds both plumbing and gasfitting licences across Sydney and the Central Coast — call 0400 073 180.
What is the difference between a gas fitter and a gas plumber?
They describe the same licensed work from two directions. “Gasfitter” is the term used in NSW licensing and in the Gas Supply Act 1996; “gas plumber” is what homeowners type into Google when they want a plumber who can also legally work on gas. The job title is not what protects you — the licence category is.
Plumber, drainer or gas fitter: which licence covers what
| The job | Licence category needed | Can a general plumber do it? |
|---|---|---|
| Replace a tap or toilet | Plumbing | Yes |
| Clear or repair a sewer or stormwater line | Draining | Only if licensed for draining |
| Install or connect a gas cooktop | Gasfitting | No — gasfitting licence required |
| Run a new gas line or gas point | Gasfitting | No |
| Find and repair a gas leak | Gasfitting | No |
| Swap an electric hot water unit for gas | Plumbing + gasfitting | Only with both |
| Install a gas space heater | Gasfitting | No |
| Commercial or industrial gas installations | Type B gasfitting authorisation | No — separate authorisation |
What counts as gasfitting work in NSW?
Gasfitting work is defined broadly by the Gas Supply Act 1996 and covers far more than most homeowners expect. If gas flows through it, or could, it is gasfitting.
- Connecting, disconnecting, altering or relocating any gas appliance
- Installing or modifying gas piping, meters, regulators and gas points
- Converting an appliance between natural gas and LPG
- Leak detection and repair on a gas installation
- Commissioning and testing an appliance after installation
- Decommissioning and capping a redundant gas line
NSW Government makes the licensing position plain: you need a licence or certificate for any plumbing, draining or gasfitting work, regardless of the value of the work or whether it is residential or commercial.
What happens if unlicensed gas work is done on your home?
The penalties are the least of it. Unlicensed gasfitting is a breach of the Home Building Act 1989 with fines up to $22,000 for an individual and $110,000 for a company — but the real risk is a gas leak or carbon monoxide from an appliance that was never commissioned properly.
- Insurance. A claim arising from unlicensed work can be refused.
- Warranty. Appliance manufacturers void warranties on installations without a compliance certificate.
- Selling the property. Undocumented gas work becomes a problem at contract stage.
- Safety. An incorrectly sized line or unflued appliance can produce carbon monoxide, which you cannot smell.
How do you check a gas fitter is licensed?
It takes two minutes and it is the single best thing you can do before booking. Ask for the licence number, then verify it yourself rather than relying on a logo on a website.
- Ask for the licence or certificate number in writing — a text message is fine.
- Check it on the NSW Government licence check and confirm gasfitting is listed, not just plumbing.
- Confirm the licence is current and in the name of the business or person attending.
- Ask whether the work is notifiable and whether you will receive a gas compliance certificate.
- Get the quote in writing before work starts.
NSW Government also publishes the compliance obligations gasfitters must meet — worth a skim if you want to know what your gasfitter is signing off on.
What gas jobs does Rectify Plumbing do most often?
Our licensed gasfitters work through Epping, Ryde, Hornsby, Berowra, Mount Colah, Thornleigh, Pennant Hills, St Ives, Parramatta and up to Gosford, Wyoming, Erina and the wider Central Coast. The bread-and-butter jobs are these.
- Gas hot water installs and changeovers — continuous flow and storage units, including electric-to-gas conversions. See our hot water services.
- Cooktop and oven connections during kitchen renovations
- New gas points for heaters, outdoor kitchens and BBQs
- Gas leak detection and repair, including pressure testing the installation
- Appliance servicing and safety checks, especially older space heaters
- LPG to natural gas conversions where the street main is available
- Decommissioning and safely capping redundant gas lines
What does a gas fitter check on a safety inspection?
A proper gas safety check is more than a sniff test. We pressure-test the installation for leaks, inspect flueing and ventilation, check the burner flame is blue and stable rather than yellow and sooting, verify appliance clearances, and confirm the meter and regulator suit the total appliance load. Older unflued heaters get the closest look, because that is where carbon monoxide risk sits.
Signs you should book a gas safety check now
- A yellow or orange flame instead of a crisp blue one
- Soot or black marks around an appliance or its flue
- A faint gas smell that comes and goes
- Headaches, nausea or drowsiness when a gas heater is running
- A pilot light that keeps going out
- Gas bills climbing with no change in how you use gas
