In an emergency
In an emergency - If you can smell gas or need to report a gas explosion/fire, call the National Gas Emergency Helpline immediately on:
0808 178 2009
Please note a gas order is NOT an emergency. Should you be able to, turn off the gas at the main shut off valve under the tank hood. For any indoor gas leak switch off the emergency valve, open doors and windows to ventilate the building and contact your installer or the engineer who maintains your appliances.
