Turning off your gas supply using the gas shut off valve
The shut-off valve for your gas supply is normally near your gas meter. It’s a good idea to know where it is in case there’s an emergency.
Give the handle a quarter turn in either direction to switch it off. The valve is closed when the handle is at a right angle to the pipe. Whether you have a standard or smart meter, shutting off the gas supply is the same and is done by the shut off valve.
All gas service shut-off valves must have a handle fitted to them. If yours is missing call the National Grid gas emergency line on 0800 111 999 as this could be dangerous.
