Install a Carbon Monoxide Alarm 


Installing an audible carbon monoxide alarm will provide an early warning in case there is a carbon monoxide leak in your home. You can buy one from a reputable DIY or hardware store, supermarket or your energy provider.

Carbon monoxide alarms give out a high-pitched noise when levels of carbon monoxide are high. However, a carbon monoxide alarm is not a substitute for maintaining and regularly servicing household appliances.

When buying a carbon monoxide alarm, you should make sure that it is Kitemarked to British Standard EN50291.

Where to install a carbon monoxide alarms

When placing and using an alarm in your home always follow the instructions supplied with the alarm. Here are some guidelines that will help you install your carbon monoxide alarm in your home:

  • The alarm should not be placed on a ceiling like a smoke alarm;
  • Place alarms in all rooms with carbon fuel burning appliances such as boilers in kitchens and fires in the lounge;
  • If you want to fix the alarm to a wall then position it at head height ( i.e. your breathing level), however the alarm does not need to be fixed on a wall (e.g. it can be placed on a table, shelf or bookcase);
  • As with smoke alarms, test your carbon monoxide alarm regularly using the test button (follow manufacturer’s instructions) and replace the batteries annually or when the low battery signal sounds;
  • Do not place the alarm in a cupboard, behind furniture, near an outside door or ventilation ( e.g. extractor fans or cooker hoods);
  • Do not place alarms directly next to fires, boilers, cookers or heaters – the alarm should be at least one metre away from any of these appliances; and
  • Do not place an alarm in areas or near sources of high condensation and steam e.g. near kettles, cooker tops, or showers.
