CO alarm going off
Different smell, different gas, same urgency. Get out first.
A gas leak is a real emergency — but a manageable one if you do the right things in the right order. The first call is SA Gas Emergency on 1800 427 532 (free, 24/7). They'll dispatch a network technician to make the property safe. Then ring us — we'll find and fix the source as soon as the network has cleared the area.
No light switches, no fans, no extractor, no phones inside the house. A spark can ignite gas. Don't even pull a plug out.
If they're already open or easy to push, open them as you go. Don't go room-to-room ventilating — just leave.
The gas meter is usually outside. Turn the lever 90 degrees so it sits across the pipe — that's OFF.
Family, pets, anyone visiting. Stand at least 10 metres from the house. Don't stand at the door.
Free 24/7. They'll dispatch a network technician within the hour for a confirmed leak.
Call 1800 427 532 nowNatural gas itself has no smell. The rotten-egg odour you can smell is a chemical called mercaptan added to the gas at the network so leaks are detectable by humans. Most people can smell concentrations way below the level that becomes dangerous, which is exactly the point. If you can smell it, the system is doing its job — you've been warned early.
For gas to ignite, it needs to be in the air at a concentration between 5% and 15%. Below 5% it's too lean; above 15% it's too rich. Most house leaks are well below 5% in the rooms you stand in, which is why most leaks don't end in explosions. They end with you smelling something off, opening a window, and ringing for help.
The dangerous moment is when a leak runs unattended for hours — gas builds up in an enclosed space (a sealed laundry, an under-stairs cupboard) and any spark from a fridge thermostat, a light switch, or static electricity can set it off. That's why the right response is: don't switch anything, get out, call.
Absolutely not. No exceptions. Repairing a gas leak — even a small one — is licensed work under the Plumbing, Gas and Electrical Services Act 1995. DIY repairs are illegal, void your home insurance, and frequently make the leak worse before they make it better.
What you can do safely: shut off the gas at the meter, ventilate, get out, call. That's it. Anything past that is for the network technician (who makes the property safe) and then a licensed gas fitter (who does the repair).
Here's how the sequence works for most Adelaide gas leak callouts:
If the leak is at a heater specifically, we can often do the make-safe ourselves on arrival without you needing the network out at all — but for any leak you can smell strongly, always call 1800 427 532 first as a safety precaution.
2026 Adelaide pricing, GST included. The SA Gas Emergency callout itself is free. Our prices are for the repair side once the property is safe.
You always get the total quoted upfront before any work starts.
Gas leaks are our top-priority callout. We'll be moving as soon as you ring, day or night, anywhere in Adelaide metro. After-hours and weekend rate is $249 — but the leak gets fixed and your gas back on tonight.
If the SA Gas Emergency network technician has already isolated the gas at the meter, you're not in immediate danger — you can also book us for the next morning if it's late at night and you'd rather not have us in the house at midnight.
