Have all gas appliances in your property serviced and safety checked annually by a Gas Safe registered engineer.

Stay aware of the symptoms of carbon monoxide poisoning – headaches, dizziness, nausea, breathlessness, collapse and loss of consciousness.

Look out for warning signs that a gas appliance isn’t working properly – lazy yellow flames, excessive condensation and black marks/stains. However, bear in mind that an appliance can be unsafe without displaying these symptoms, so best practice is to have your appliances checked every year.

Buy an audible carbon monoxide alarm and install it (in accordance with manufacturer’s guidelines) near to your gas appliance. Alarms are a strong second line of defence against carbon monoxide poisoning.

Use gas appliances for their intended purposes only, e.g. do not use a cooker to heat a room.

Provide enough ventilation for gas appliances to burn correctly and make sure no air vents or chimneys are blocked.

If you know of anyone working outside of Gas Safe registration, they are breaking the law.  You can report them to Gas Safe by calling 0800 408 5500 or through their website www.gassaferegister.co.uk.
