You can normally smell gas if there’s a leak.
If you think there’s a leak, you should:
- open all your doors and windows
- put out any naked flames - like a candle - and do not smoke
- shut off the gas at the main supply if it’s safe to
- leave any electrical switches or appliances alone - do not touch them
- go outside and call the national gas emergency number on 0800 111 9999
Do not go back inside or turn the gas on unless you’ve been told it’s safe by a gas engineer.
You should then let us know about the leak.
