The smell of gas in your home is something you should never ignore. Natural gas and LPG are both odourised so you can detect leaks — that distinctive rotten egg smell is there for your safety. Here is exactly what to do if you smell gas.
Step 1: Do Not Create Any Sparks
This is the most important thing. Do NOT:
Turn any light switches on or off
Use any electrical appliances
Use your phone inside the house
Light matches, lighters, or candles
Start your car if it is in an attached garage
Any spark can ignite leaked gas. Even flipping a light switch can be enough.
Step 2: Ventilate
Open doors and windows to let fresh air in and gas out. Do not use extractor fans or any electrical ventilation — just open things manually.
Step 3: Turn Off the Gas Supply
If you can safely access your gas meter or LPG bottle, turn it off. The valve is usually a lever or tap on the meter — turn it to the off position (perpendicular to the pipe).
Step 4: Get Everyone Out
Evacuate everyone from the house including pets. Move well away from the property.
Step 5: Call for Help
Once you are safely outside and away from the building:
For natural gas leaks: Call the gas emergency line on 0800 GAS 888 (0800 427 888)
If you feel unsafe or the leak is severe: Call 111
For a gasfitter to locate and repair the leak: Call Water and Gas Worx on 0800 322 322
Common Causes of Gas Leaks
Faulty or old gas appliances — cooktops, heaters, hot water systems
Damaged gas pipes — corrosion, accidental damage during renovations
Poor connections — improperly fitted appliances or fittings
LPG regulator issues — worn seals or faulty regulators on gas bottles
How to Prevent Gas Leaks
Regular servicing: Have your gas appliances serviced by a qualified gasfitter every 2 years
Gas compliance certificates: Ensure all gas work is done by a certified gasfitter and comes with a certificate of compliance
Know your system: Learn where your gas meter or LPG shutoff is before you need it
Install a gas detector: Consider a gas alarm in your kitchen or near gas appliances
