Gas leaks and gas safety at home

​Gas is a safe fuel when used and serviced correctly but, as with all fuels, it should be used responsibly and all gas appliances kept well maintained to ensure safe and efficient operation.

What should I do if I can smell gas?

If you smell gas, think you have a gas leak, or suspect that fumes containing carbon monoxide are escaping from a gas appliance, call 755555 immediately (this is a 24-hour line.  All investigations for gas leaks are free of charge).

  • don't smoke
  • don't use naked flames
  • don't turn electric switches on or off
  • switch off the gas appliance
  • turn off your gas supply at the emergency control valve (usually next to your gas meter)
  • open all the doors and windows
  • leave the property

Why are ventilation and flues so important?

To help operate safely, all gas appliances need the following:

  • an adequate supply of air to help the complete combustion of gas
  • 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.  The early symptoms of carbon monoxide poisoning are:

  • tiredness
  • drowsiness
  • dizziness
  • chest pains
  • nausea

There are some easy ways to help avoid the build up of carbon monoxide poisoning:

  • never block air bricks or vents
  • ensure that flues are kept clear at all times 
  • have your gas appliance regularly maintained and annually serviced

Should I get a carbon monoxide alarm?

Because you can’t see, taste or smell carbon monoxide, a carbon monoxide (CO) alarm is one useful precaution to give early warning of CO in a property.  However, a CO alarm should not be thought of as a replacement for regular maintenance and service of your gas appliance.   Fit an audible carbon monoxide alarm, which can wake you if you are sleeping.

Before buying a CO alarm, make sure it complies with British Standard EN 50291 and carries a British or European approval mark, such as a Kitemark.  CO alarms should be installed and maintained in line with the manufacturer’s instructions.
