Using electricity and gas safely

Turning gas supply off and on

Before turning your gas supply off or on, make sure you first turn off all gas appliances and pilot lights in your home, eg gas cooking appliances, heaters, and water heaters. If you have a gas water heater, turn the water supply tap off, too.

Natural gas supply

Locate your gas meter – it may be in a metal box on the side of your house, or in your front garden under a plastic cover.

To turn off the gas supply into your home, turn the supply valve tap to the horizontal off position (at a right angle to the pipe). To turn it on, turn the supply valve tap to the vertical on position (in line with the pipe).

If you don't know where your gas meter or supply valve is, contact your gas provider.

LPG supply

Locate your LPG cylinder(s). In most cases, it will be installed on a concrete slab against or near the house.

To turn off the gas supply into your home, turn the round valve at the top of the cylinder in a clockwise direction until it won’t turn anymore. If you have more than one cylinder, make sure you turn them both off. To turn the gas supply on, turn the valve anti-clockwise.

Lighting appliances

  • Make sure you read and understand the manufacturer’s instructions for your gas appliances before turning them on and lighting any pilot lights.
  • If a licensed gas fitter has just installed a new appliance for you, ask them to show you how to use it properly.
  • If you’re using a match or lighter to light a gas appliance, light the match or lighter before turning on the gas. If the gas doesn’t light or your flame goes out, turn off the gas and wait a few minutes before trying again.
  • If your appliance won’t light
    • Check your gas supply is turned on before calling a licensed gas fitter to have it checked
    • If the appliance is under warranty, call the retailer or manufacturer
    • If your gas supply won’t turn on, contact your gas supplier.
    • If the gas supply company isolated your gas supply, they’ll help you restore the gas and relight your appliances. If you’re not home when they come to help, they’ll leave a brochure to guide you through the steps for relighting appliances.
  • If your gas supply has been turned off and back on again, air can get trapped in the gas pipes in your home. The first appliance you light will purge any trapped air but may take a few moments to light while the gas flows from the meter. If there is air in the pipework, the appliance you light may go out shortly after. Turn it off, wait a few minutes for the unburnt gas to disperse, then try to light the appliance again. Once it is lit, let it burn for at least three minutes so the gas is flowing properly. Gas cooktops are the easiest appliances to light first, if you have one.
