What do I do if I smell gas?
If you think you can smell gas and may have a gas leak, or are worried about one of your appliances, call the Gas Emergency Service on 0800 111 999. You can also call this number if you’re worried about one of your appliances giving off carbon monoxide (CO), but remember that you cannot see, smell or hear CO.
If you smell gas but you are not in immediate danger:
- Call National Grid's Gas Emergency Service Freephone number 0800 111 999 – from a landline at a different property or using a mobile phone, away from the leak
- Open all the doors and windows
- Don’t smoke, light a match or any other naked flame
- Don’t turn lights on or off and avoid using other electrical switches and appliances as this could trigger an explosion.
If you or your family are in immediate danger, exit the premises immediately and call 0800 111 999.
