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. It should be marked to
EN 50291 and also have the British Standards’ Kitemark or another European approval organisation’s
mark on it. CO alarms usually have a battery life of up to 5 years.

Fit an alarm in each room with a gas appliance. Always follow the alarm manufacturer’s instructions
on siting, testing and replacing the alarm.

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.
