Knowing what to do in an emergency could save lives. Whether you’re at home or out and about, there are some essential things to do if you suspect a gas leak.
If you think you have a gas leak or can smell gas, leave the house and phone the National Gas Emergencies number immediately on 0800 111 999.
If you’re at home, and you can do it safely, turn off your gas supply. The gas mains tap should be beside your gas meter. Move the handle a quarter turn until it's at 90 degrees from the pipe to shut off the gas supply.
