If you smell gas call the National Gas Emergency Service on 0800 111 999

Stay safe in 3 easy steps

Here's what to do:

Step 1 - Call us immediately on freephone 0800 111 999

We’re available 24 hours a day, 365 days a year and will send out an engineer to keep you and your property safe

Step 2 - Open windows and doors

Open all your windows and doors to ventilate the property/area

Step 3 - Turn off all your gas appliances

If possible, switch off the gas at the meter using the Emergency Control Valve (ECV) (unless the meter is in the cellar or basement, in which case don’t go in).

DO NOT:

Use any electrical appliances - this includes switching your lights on or off
Do not smoke or use naked flames
If there’s a smell of gas in the cellar or basement - please wait outside or with a neighbour until an emergency engineer arrives

What happens next?

Once we have stopped the gas leak, our engineer will explain that any work on appliances (e.g. cookers, boilers or fires) has to be carried out by a Gas Safe Registered engineer. You can find details of Gas Safe Registered engineers here.
