What do I do if I think I have a gas leak?

Open doors and windows.

Check if the pilot light has gone out. If any gas appliances have been left on, turn them off. If the pilot light is still on and your gas appliances are all off there may be a gas escape.

Turn off the gas at the mains.

Phone the National Gas Emergency Number immediately on 0800 111 999. (Do not call from a mobile phone). Please do not send us an email or use the 'Contact us' page on this site to report a gas leak.

Do not turn lightswitches on or off, use doorbells, mobile phones, or any other electrical switches.

Do not smoke, light a match or use any other kind of naked flame.

If your mains tap is in an external meter cabinet, make sure you know where the key is. If you don't have a key, phone us on 0845 755 2233.
