Straightforward & easy to fit. Not interlinked with fire alarm system. Turned out to be a plus point because every unit interlinked adds a complication to the system. Scotyland has a legal requirement to interlink fire alarms but not the CO alarms (although this can be done).

Carbon Monoxide Poisoning

Many people are unaware of the devastating effects of carbon monoxide poisoning. Carbon Monoxide has no colour, smell or taste and cannot be detected by the human senses. It is extremely dangerous, binding itself to the haemoglobin in red blood cells and preventing them from transporting oxygen around the body.


Estimated Number of Deaths Every Year

According to statistics released by the Office for National Statistics, throughout England and Wales there are an average of over 60 deaths every year due to accidental exposure to carbon monoxide - up to 45% of which occur in the home.

People Treated for CO Poisoning Every Year

Figures from the Department of Health and Social Care show that there are around 4000 cases of carbon monoxide poisoning treated in A&E Departments across England each year - even mild cases can exacerbate existing conditions such as respiratory illnesses, leading to fatalities.

Number of People Hospitalised Every Year

According to the Chief Medical Officer (CMO) for England, around 200 per year are hospitalised in England and Wales as a result of accidental carbon monixide posioning.

Percentage of UK Households with a CO Alarm

A study of more than 27,000 properties by the Liverpool John Moores University, supported by the Merseyside and West Midlands Fire Services, found that less than 10% of homes have a single carbon monoxide alarm to protect occupants from this deadly gas.
