It’s crucial to act quickly in a gas emergency.
These are the steps you need to take to stay safe:

• Get fresh air immediately: Make sure you open all doors and windows to ventilate the area.
• Turn off the gas emergency control valve (also called gas emergency shut off valve) at the meter, unless the meter is located in a basement or cellar or at the LPG bulk tank or storage vessels.
• Extinguish all naked flames and don’t smoke.
• Don’t operate electrical switches (including turning light switches on or off) because this can ignite escaping gas.
• Call the National Gas Emergency Service on 0800 111 999 and let them know you smell gas. The number operates 24/7 and is free to call.
• The helpline will advise you what steps to take next. They will also send out an emergency gas engineer from your local distribution network who will ensure steps are taken to make the situation safe. The engineer will require entry to the property in order to make it safe for you.
• Where advised, contact a Gas Safe registered engineer to fix the appliance and check it’s safe.
• If you’re feeling unwell, visit your GP or hospital immediately and let them know you may have been exposed to carbon monoxide.
• Don’t turn the gas supply on again until it’s been checked by a Gas Safe registered engineer.
