If you think a gas appliance isn’t working properly make sure you don’t use it. Do not try and investigate the problem or attempt to fix a leak or a faulty appliance yourself.

It is illegal for anyone to use a gas appliance if they suspect it is unsafe. Turn the appliance off and do not touch it until it has been checked by a Gas Safe registered engineer.

If you suspect there is a gas leak you should immediately do the following:

• Call National Grid's Gas Emergency Freephone number: 0800 111 999
• Open all the doors and windows
• Turn the gas off at the mains if possible, unless the meter is located in the cellar or basement.
• Opening doors and windows to let air in,
• Check that the pilot light has not gone out and check that all gas appliances are off. If the pilot light is still on and your gas appliances are all off, there may be a gas escape
• Do not turn lights on or off and avoid using other electrical switches and appliances as this could trigger an explosion.
• Don’t smoke, light a match or any other naked flame.

If you do smell gas, then call 0800 111 999 for England, Scotland and Wales.

Make sure that grilles, outside flues and ventilation bricks aren’t covered or blocked. Why are ventilation and flues so important?

• So that an adequate supply of air is available to help the complete combustion of gas;
• To allow efficient operation of their flue to remove any combustion products, including carbon monoxide (CO), that are produced

Without these safety precautions dangerous levels of carbon monoxide can build up with the possibility of fatal consequences. There are some easy ways to help avoid the build up of carbon monoxide poisoning.
