Carbon Monoxide – BS EN 50292:2023

What is the British Standard BS EN 50292:2023?

Carbon Monoxide (CO) is a silent killer, you can’t see it, smell it or taste it. This is why having Carbon Monoxide alarms installed throughout a property is so important. The British Standard BS EN 50292:2023 offers recommendations on the installation and maintenance of Carbon Monoxide alarms.

Where should CO alarms be installed?

The standard states that a Carbon Monoxide alarm should be fitted in:

  • Rooms that have any fuel burning appliances – such as an open fire, gas cooker or boiler
  • Rooms where people spend the most time – such as a living room
  • Rooms where people sleep
  • Any room that has a flue running through it
  • Rooms which are not normally frequented that have a fuel burning appliance (for example a boiler room)
  • Humid rooms with a fuel burning appliance (e.g the bathroom), the CO alarm should be suitable for bathrooms as per manufacturers guidance.

CO can also be produced by appliances burning:

  •  Ethanol
  •  Wood pellets

This means that a Carbon Monoxide leak can be detected from all the potential sources and heard throughout the property.


What else should I consider?

You should look for a product that has been manufactured and approved (e.g. Kitemarked) to standards BS EN 50291-1:2010 (for domestic premises) and/or BS EN 50291-2:2010 (for caravans and boats). These standards show that the alarms have been extensively tested to ensure their quality including sensor reaction times, minimum alarm sound levels and temperature resistance.
