Leave the property.
- Call Cadent on 0800 111 999 first.
- Do not use a mobile or cordless telephone unless you are outside the property, or away from the suspected leak.
- If you have difficulties hearing, you can contact the National Grid by textphone (Minicom) on 0800 371 787.
If you feel it is safe to do so, turn off the gas at the main supply (at the gas metre), then:
- Open all doors and windows to ventilate the property.
- Do not use any electrical equipment or turn any lights or sockets on/off.
- Extinguish all naked flames (gas cookers and fires) – do not smoke, strike matches or do anything else that may cause a spark.
Look out for the engineer and open the doors manually, if you have electrical entry phones/locks/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.
Check to see whether a gas tap has been left on or the pilot light has blown out on any gas boilers or appliances
