Emergency Gas Leak? How Perth Homeowners Should Respond
- •A gas smell indoors is always an emergency — treat it that way, every time.
- •The first 60 seconds matter: know exactly what to do before panic sets in.
- •Never use switches, flames, or phones inside the house if you suspect a leak.
- •Only a licensed gas fitter can legally inspect and clear your gas system in WA.
- •Fixed-price emergency call-outs mean no nasty surprises when you need help most.
You wake up at 2am to a smell you can’t quite place — rotten eggs, sulphur, something chemical. Your gut tightens. That smell is added to Perth’s natural gas supply precisely so you’ll notice it, and if you’re smelling it right now, every second you hesitate costs you. Here’s exactly what to do.
Why Is a Gas Leak So Dangerous in a Perth Home?
Natural gas is odourless by nature — the smell is the only warning you get.
Gas suppliers add a chemical odorant so leaks are detectable before concentrations reach dangerous levels. But even a small leak can build up quickly in an enclosed space — enough to ignite from a light switch, a phone screen, or even a door friction spark.
Perth homes use gas for hot water, cooking, and heating — which means pipework runs through kitchens, laundries, and roof spaces. A leak in any of these areas can go unnoticed until concentration reaches a critical point. Don’t wait to find out which kind you’re dealing with.
Step 1: Stop What You're Doing and Don't Touch Anything Electrical
The urge to flick a light on or grab your phone can make things far worse.
Do not turn lights on or off. Do not use your mobile phone inside the house. Do not open the fridge, start the rangehood, or press any switches. Even a small electrical arc can ignite accumulated gas.
Never re-enter your home after evacuating for a gas leak until a licensed gas fitter has inspected the property and given the all-clear. This is a legal requirement in WA, not just a recommendation.
Step 2: Get Everyone Out and Open Doors as You Leave
Ventilation buys time — but outside is the only safe place to be.
As you exit, open windows and external doors if you can do so without operating any powered mechanisms. This dilutes gas concentration and reduces ignition risk. Don’t stop to collect belongings — move people and pets out immediately.
Once outside, move well clear of the building — at least to the street. Gas can accumulate along the ground and follow you if you stay close to the structure.
Step 3: Turn Off the Gas at the Meter — If It's Safe to Reach
Your meter is usually near the front of the property — learn where it is before you need it.
Most Perth homes have a gas meter near the front boundary or on an external wall. If you can reach it without re-entering the building, turn the valve a quarter-turn so it sits perpendicular to the pipe — that shuts off supply.
If the meter is inside or you’re not sure, skip this step and call for help immediately. Shutting off gas is useful but not worth risking your safety — emergency services can do this on arrival.
Walk around your property now — before an emergency — and locate your gas meter. A 30-second familiarisation today could save critical time at 2am. For guidance on detecting and preventing gas leaks in outdoor areas, this resource covers what Perth homeowners often overlook.
Step 4: Call Emergency Services and a Licensed Gas Fitter
Make your calls from outside — never from inside a building where gas may be present.
From outside, call 000 if you believe there is immediate danger — fire, a person unable to evacuate, or a rapidly worsening smell. Then call your gas emergency line and a licensed gas fitter who handles after-hours callouts.
Plumb It Right handles emergency gas leak callouts across Perth, including after-hours situations. As part of the broader response covered in our hub on Emergency Plumber Perth: 24/7 Fast Response for Every Plumbing Crisis, gas leaks sit at the top of the urgency scale — they are never a wait-until-morning situation.
What Happens When the Gas Fitter Arrives?
A licensed inspection is the only way to legally confirm your home is safe to re-enter.
Your gas fitter will use detection equipment to locate the source of the leak — whether it’s a faulty appliance connection, corroded pipework, or a joint that’s worked loose over time. They’ll isolate the fault and test the system before any gas is restored.
In some cases, a full pipe pressure test is required before gas can be turned back on. This isn’t bureaucracy — it’s the standard that protects your household. Only after a written clearance can you safely re-enter and resume normal use.
If the leak has caused damage to an appliance or your hot water system, your gas fitter can advise whether repair or replacement makes more sense — similar decisions come up in scenarios like an After-Hours Hot Water System Failure in Perth: Emergency Repair or Replace?
How Do You Prevent Gas Leaks Before They Happen?
Most gas emergencies are preventable with basic annual maintenance.
Annual gas appliance servicing catches deteriorating connections, cracked flexible hoses, and faulty regulators before they become emergencies. It’s the single most effective thing you can do to protect your household.
- •Have flexible gas hoses on appliances checked every 5 years — they degrade silently.
- •Never use outdoor gas appliances indoors, even temporarily.
- •If you smell gas after a storm, treat it as an active leak — ground movement can shift pipework.
- •Any DIY gas work is illegal in WA — always use a licensed gas fitter for connections and repairs.
Understanding the cost of an emergency callout upfront removes one barrier to calling when you should.

Common Questions About Gas Leak Emergencies in Perth
Straight answers to what Perth homeowners ask most when gas becomes a concern.
Can I Stay in the House If the Smell Is Faint?
No. A faint smell can indicate a slow leak that is still accumulating in your home. Gas concentration builds faster than you expect in closed spaces. Evacuate, ventilate, and call a licensed gas fitter — do not wait to see if it gets worse.
Is It Safe to Use My Mobile Phone to Call for Help?
Make your calls from outside the building, not inside. Mobile phones can produce a small electrical arc when a call connects or a notification arrives. Once you’re clear of the building, call freely — just don’t go back inside to retrieve a phone you’ve left behind.
How Long Does an Emergency Gas Inspection Take?
It depends on the fault, but a licensed gas fitter can typically locate and isolate the leak and pressure-test the system within a few hours for most residential situations. More complex faults — damaged underground lines, for example — may take longer and require a follow-up appointment.
What If My Gas Leak Is Near an Outdoor BBQ or Kitchen Area?
Outdoor gas connections carry the same risks as indoor ones, especially if flexible hoses have degraded or connections have worked loose. Turn off the gas bottle or meter, keep ignition sources away, and have a licensed gas fitter inspect the fitting. For more detail on gas leak detection and repairs in the Perth area, professional inspection is always the safest path forward.
