Why are ventilation and flues so important?

To operate safely, all gas appliances need the following:

  • an adequate supply of air to help the complete the combustion of gas, and
  • the 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:

  • never block ventilation
  • ensure that flues are kept clear at all times, and
  • have your gas appliances regularly maintained and annually serviced by a Gas Safe registered engineer.

What to do if you suspect there’s a gas leak

You should immediately:

  • Call National Grid’s Gas Emergency Freephone number: 0800 111 999
  • Open all the doors and windows
  • Shut off the gas supply at the meter control valve (if you know where it is)
  • Turn the appliance off and do not touch it until it has been checked by a Gas Safe Registered engineer

Warning! It is illegal for anyone to use a gas appliance if they suspect it is unsafe.

Call BHE as soon as possible if you think you have a leak.
