fit a carbon monoxide alarm

Carbon monoxide kills if left undetected

For the safety of you and your family, it is advisable to fit a carbon monoxide (CO) alarm in your home. Just like a smoke alarm which alerts you to the presence of smoke, a carbon monoxide detector will alert you to the presence of CO.

The difference with CO is that it is invisible and has no smell or taste, so you might not realise it is there.

Smoke alarms do not detect carbon monoxide.

What alarm should I fit?

Gas Safe Register recommends the use of audible carbon monoxide alarms marked with British Standard EN 50291. It should also have a British or European approval mark, such as a Kitemark. CO alarms usually have a battery life of up to 5 years.

Fit an alarm in each room with a gas appliance. Read the manufacturer’s instructions before installing it.

Do not use the ‘black spot’ detectors that change colour when carbon monoxide is present, they don’t make a sound. It is important to choose an alarm that will wake you up if you’re asleep, or you may not be aware of early CO symptoms until it is too late.

Where can I get an alarm?

Carbon monoxide alarms are available from DIY retailers and cost around £20. They are usually found in the home security section.

Ask your Gas Safe registered engineer if you are not sure which alarm to buy or how to fit it – your engineer will be able to advise you.

A carbon monoxide alarm is no substitute for correct installation and servicing of your gas appliances. Make sure you get your appliances checked by a Gas Safe registered engineer.
