From heating to cooking, we use gas appliances every day. We want you to be able to use your gas appliances safely and without worry. To do this, everyone needs to follow some gas safety rules.

Below you’ll find information on what to do if you smell gas. There’s also advice on gas safety checks and certificates to help you be gas safe.

If you can smell gas or suspect you have a leak

If you think you've got a gas leak in your home or can smell gas anywhere outside, leave the house or area and call the National Gas Emergency Service immediately on 0800 111 999

Only use a mobile phone outside, well away from the leak.

Don't send us an email or use the contact us page on this site to report a gas leak. Always call the gas emergency number.

Gas safety tips

  • Get any gas appliances installed and regularly serviced by a Gas Safe registered engineer.
  • Don't use any gas appliances that you think aren’t working properly.
  • Make sure that ventilation bricks, grilles or outside flues aren't covered or blocked.
  • Fit a carbon monoxide detector to use as a guide only. Don't rely on it completely.

Gas safety checks and certificates

Make sure you get a Gas Safe registered engineer to service your gas appliances at least once a year. By law, gas engineers must be registered to be able to work on gas installations. All our gas engineers are Gas Safe registered engineers.

If you’re an SSE customer, you might qualify for a free gas safety check. If you live in rented accommodation, your landlord must arrange an annual gas safety check.

You’ll find more details in our guides to gas safety checks and gas safety certificates.

Gas detector alarms

Gas detector alarms can alert you to a gas leak in your home. Make sure you have the alarm installed by a Gas Safe registered engineer.

You should also have a Carbon Monoxide (CO) detector installed in your home. Carbon monoxide is colourless, odourless and can be fatal.

You can find out more in our guide to carbon monoxide safety.
