Carbon monoxide

If you think there's a carbon monoxide leak call the gas emergency number 0800 111999

  • stop using all appliances, switch them off, and open doors and windows to ventilate the property
  • leave the property immediately – stay calm and avoid raising your heart rate
  • don't go back into the property
  • seek immediate medical help

Faulty gas appliances can produce carbon monoxide. You cannot smell it, taste it or see it but it can kill. Symptoms of carbon monoxide poisoning include sleepiness, headaches, chest pains, erratic behaviour, diarrhoea and feeling sick, particularly when gas appliances are being used.

Other warning signs to look out for:

  • sooty marks or yellow/brown stains around the appliance
  • an appliance burning with a yellow or orange lazy flame and not a crisp blue flame
  • smoke in one room – this could show that a chimney or flue is blocked

We have completed the installation of carbon monoxide detectors to all dwellings where there is a fixed combustion appliance (excluding gas cookers).
