Make people safe
Open doors and windows if you can do so safely without delaying escape, then get everyone outside and keep others away. If safely accessible, turn off gas appliances and the gas supply at the meter’s emergency control valve (usually a handle turned a quarter-turn/90 degrees). Never enter a cellar or basement to reach a meter or investigate a leak. Do not smoke, light flames, turn electrical or light switches on or off, or use equipment that could spark. Do not use your phone inside the affected area. Call 0800 111 999 from outside and follow the adviser’s instructions. Do not re-enter until the emergency engineer says it is safe.
