Follow these steps to safely turn your gas back on at the meter

Open some doors and windows in your property for ventilation.

Give the emergency control valve (a spanner-style handle close to the gas meter, pictured below) a quarter turn in either direction, setting it in line with the gas pipe. Some pipes have yellow tape to help guide you. There may be a slight hissing noise as the meter re-pressurises.

If you smell gas, turn the emergency control valve off again and call the National Gas Emergency Service on 0800 111 999 immediately. Do not try to turn any appliances back on.
