Smell gas / suspected gas leak

Do this immediately

1. Call the National Gas Emergency Service: 0800 111 999 (24/7).
2. Open doors and windows to ventilate.
3. Do NOT turn any electrical switches on or off, use the phone indoors near the smell, or light anything.
4. Turn the gas off at the meter control valve (lever a quarter-turn so it’s across the pipe) — only if safe to reach.
5. Leave the property and take the pets. Call from outside.

Gas meter / emergency control valve location: CONFIRM, e.g. meter box on external wall.

Carbon monoxide

If the CO alarm sounds or you feel dizzy/headachey/nauseous: get everyone (and pets) into fresh air, call 0800 111 999, and seek medical advice.
