What to do if you smell gas, or suspect a leak
First, turn off any gas appliances, open the doors and windows and leave your home immediately.
Then call the Gas Emergency services on 0800 111 999, and afterwards, call us. Don’t use your mobile or a cordless phone unless you are outside your home and away from the suspected leak.
If you have hearing difficulties, you can contact the National Grid by textphone on 0800 371 787.
Follow the guidance of the emergency services. If told to leave your home or to stay outside, do not go back in.
Only if you’re told it is safe, turn off the gas at the main supply (at the gas meter), then:
- Do not use any electrical equipment or turn any lights or sockets on or off
- Extinguish all naked flames, such as gas cookers and fires
- Do not smoke, strike matches or do anything else that may cause a spark
- Check if a gas tap has been left on. See if the pilot light has blown out on any gas boilers or appliances.
Look out for the engineer and open the doors manually if you have electrical entry phones, locks, or doorbells. It’s a good idea to put a note on the outside of the door warning people not to use the electrical door entry system or doorbell.
