Gas is the one trade where a cheap job can hurt someone. If you smell gas anywhere in the Hills District, the first 60 seconds matter more than the plumber. This page covers that drill, who is legally allowed to touch your gas in NSW, the certificate you must be given after any gas work, and the questions that sort a licensed gas fitter from a handyman.

Smell gas? The 4 things to do in the next 60 seconds
- No flames, no switches. Lights, appliances, doorbell: leave them all as they are.
- Open doors and windows.
- Turn the gas off at the meter. A quarter turn so the handle sits across the pipe. For bottles, close the valve on the cylinder.
- Everyone outside, then call. If the smell is strong or you cannot reach the meter, ring the gas network’s emergency line first (in most of Sydney that is Jemena, 131 909) or 000, then ring us.
The one thing you must not do: look for the leak with a lighter.
Who can legally touch your gas in NSW
Only a licensed gasfitter can install, alter, repair or disconnect gas pipework and appliances, and the business quoting you must hold a contractor licence covering gasfitting. A general plumbing licence alone is not enough. Check the number on the NSW Fair Trading licence check. Ours is 339748C.
The gas compliance certificate you must be given
After gasfitting work in NSW the licensed gasfitter must issue a Certificate of Compliance for the gas work. It records what was done, that it was tested, and who did it. Your insurer, a buyer, a strata manager or a tenancy inspector can all ask for it. No certificate means the person was not allowed to do the job.
What unlicensed gas work really costs
- A leak found by the next licensed tradesperson, who must shut your gas off until it is fixed.
- A refused insurance claim.
- A cooktop or heater disconnected and redone, so you pay twice.
- Carbon monoxide from a badly flued heater.
5 questions to ask a gas fitter before they start
- “What is your licence number and does it cover gasfitting?”
- “Will I get a Certificate of Compliance when you finish?”
- “Is the price fixed before you start?”
- “Will you pressure test the whole line, or just the new part?”
- “Does the price include the flue, the regulator and the isolation valve?”
Gas leak test, explained
The pipework is put under pressure with the appliances isolated and a gauge is watched for a set time. Holding pressure means a sound line. A drop means a leak, found section by section with soapy water or a detector at every joint. Every gas job we do finishes with this test, and it is on the certificate.
Before you move that cooktop
A like-for-like cooktop swap is a short job: isolate, disconnect, fit, connect, test, certify. Moving it, or switching to induction, means new pipework or a capped line, possibly an electrician, sometimes a benchtop cut. Tell us which and we price it on the phone.
Gas or electric: the real numbers
It depends on what you run and your tariff. Gas cooktops are cheap and instant; induction is now as fast and often cheaper to run. For hot water, gas continuous flow and heat pumps are the two efficient options and we fit both. For heating, a reverse-cycle split usually beats gas on running cost. We give you the numbers for your appliances, not a slogan.
Why your gas bill jumped
In order: a hot water unit working harder because a tempering valve or thermostat has failed; a small leak on an old fitting; a heater with a blocked flue; a price rise; an estimated meter read. A leak test and a look at the hot water unit settle the first three in one visit.
Read this before you relight
If the appliance went out and you smell gas, do not relight it. Ventilate, gas off at the appliance, call. If there is no smell, follow the appliance instructions and wait five minutes between attempts. If it keeps going out, the thermocouple or pilot assembly needs a gasfitter.
The gas job nobody should DIY
Any of it: a bayonet, a cooktop, a barbecue connection, a regulator, a line to the outdoor kitchen. It is illegal without a licence in NSW, it voids insurance, and the failure is a fire, not a puddle. The small jobs are quick for us and cheap for you.
