Why The Law Keeps Gas Licensed In Balmain
In NSW, every job on a gas installation: connecting a cooktop, moving a bayonet, repairing a line: must legally be done by a licensed gasfitter, and for good reason: the failure modes are leaks, fires and carbon monoxide, none of which give second chances. It is also why "the handyman hooked it up" appliances are the single most common source of the leaks we get called to.
Licensed does not just mean allowed. It means the job finishes with a manometer pressure test proving the whole installation holds, appliances checked for correct operation and ventilation, and work done to AS/NZS 5601, the standard that decides what your insurer thinks of the installation if anything ever goes wrong. Across Balmain and the Inner West, that is the finish line on every gas job we do.
Ventilation, flues and living close to the water
Gas installations and appliances are governed by AS/NZS 5601:2022, referenced in the Gas and Electricity (Consumer Safety) Regulation 2018 and legally enforced in NSW (NSW Government), covering pipe sizing, ventilation and appliance clearances. It is licence-only work.
Homes near the water are often closed up tighter against wind and weather than their inland equivalents, and modern draught-proofing has made that more pronounced. Gas appliances need air, and a well-sealed room changes the ventilation calculation.
It matters most for older heaters and anything unflued. If a room with a gas appliance has been renovated to be more airtight, the appliance should be re-assessed for that room rather than assumed still suitable.
Old steel lines and what is inside them
Gas runs in older homes are frequently black steel, and steel corrodes internally over decades. The bore narrows with scale, which starves appliances at the far end of the run, and the wall thins at the low points where moisture collects.
Every job finishes on a pressure test with a certificate. Gas has no visible half-finished state: an installation either holds and is certified, or it is not complete.
An appliance that has become unreliable at the end of a long old run is often reporting on the pipe rather than on itself. That is worth establishing before it gets replaced.
Damp, corrosion and the meter position
Meters and regulators on the weather side of a property near the water take the worst of it, and a corroded regulator is both a supply problem and a safety one.
Sizing is the quiet failure. Adding an appliance to a line that was adequate for the original load can starve everything else on it, so we check what the existing run can actually carry before extending it.
Relocating or shielding a badly exposed meter assembly is straightforward work that is rarely done until something fails. If yours is green, crusted or streaked with rust, it is worth raising.
If you smell gas, this is the order
Leave the building. Take everyone with you. No light switches, no appliances, no phone calls made inside: a switch operating is an ignition source.
From outside, call 131 909. That is the gas network's emergency number, staffed twenty-four hours, and they attend and make the supply safe at no cost to you. Once it is safe, a licensed gasfitter finds and repairs the fault on your side of the meter.
Carbon monoxide: the risk with no smell
Gas that burns incorrectly produces carbon monoxide, which has no odour and no colour. It is the reason a badly serviced heater is more dangerous than a leaking pipe, the leak announces itself and this does not.
The visible warning is flame colour. A gas flame should burn blue. Yellow or orange flames, soot around an appliance, or condensation on windows when a heater runs all mean stop using it and book a service.
What a pressure test actually proves
The installation is isolated, brought to a set pressure, and watched on a manometer for a defined period. If the needle holds, the system is tight. If it drops, gas is escaping somewhere and the test tells us roughly how much.
It is the only way to know the condition of pipework you cannot see, and it is the step people most often want to skip. It is also the step that finds the uncapped line behind the old stove.

Appliance connections, from ~$200
Cooktop, oven or heater connected, tested and certified. More if a new line or bayonet has to be run to reach it.
Gasfitter rates, $120–$220/hr
The going Sydney range for licensed gas work in 2026, with call-out fees typically $80–$150.
Every gas job ends with a pressure test and the paperwork that proves it. Figures here are indicative of the 2026 Sydney market rather than a quote from us, you get your own number as a fixed price before any work starts.
How A Gas Job Runs
Step 01
Step 01
Make It Safe
A suspected leak starts with isolation at the meter and ventilation, before diagnosis, before anything. No reading is worth taking on an installation still feeding a leak.
Step 02
Find It, Prove It
A manometer pressure test tells us the installation is losing gas; gas detection equipment and controlled testing narrow it to the joint, fitting or run responsible.
Step 03
Repair To Standard
The failed component or section is replaced, not doped up and hoped over, to AS/NZS 5601, whether that is one connector or a rerun line.
Step 04
Test, Relight, Certify
The whole installation holds pressure or the job is not finished. Appliances are relit and checked for correct burning, and you get the compliance side documented.
New Appliance Still In Its Box?
New cooktop in its box, a bayonet that needs moving, or a smell you are not sure about: call and it gets done properly.
Indicatively: a pressure test and leak location $220-$450; a new bayonet or appliance point $350-$800 depending on the run; an appliance service $180-$320; a cooktop changeover $250-$500 where the point already exists. Market figures for 2026, not a quote, and every job includes the compliance certificate rather than adding it.
The installation is isolated, brought to a set pressure and watched on a manometer for a defined period. If the needle holds, the system is tight; if it drops, gas is escaping and the test indicates roughly how much. It is the only way to know the condition of pipework you cannot see.
No. Gasfitting is licensed work in NSW with no handyman tier, and that is not bureaucratic caution, unburnt gas and incorrectly burnt gas are both lethal, and the second is odourless. Unlicensed gas work also voids home insurance, invalidates appliance warranties, and surfaces during a sale.
A corroded regulator is both a supply problem and a safety one, and meters on the weather side of a waterside property take the worst of it. Relocating or shielding a badly exposed meter assembly is straightforward work that is rarely done until something fails.
Not necessarily. Redundant pipework from a disconnected heater, a removed stove or a converted fireplace is not always capped to any standard, or capped at all. It is the single most common reason an old house fails a pressure test, and usually inexpensive to put right once located.
That is the right question to ask first. A pool heater can exceed the rest of the house combined, so the issue is never the appliance, it is whether the meter and run can carry it. Establish that before ordering, the alternative is an expensive heater that never reaches temperature.
It can be, and testing is the only way to know. A period home was not built with gas in mind, whatever it has was added later, often several times, taking whatever route was available. The first job is usually establishing what is actually there before anything is added to it.
