Carbon Monoxide Detectors

Need help? Need help? What are the benefits of installing CO detectors? The UK’s Most Effective Carbon Monoxide Detectors - Buy Now
Carbon monoxide poisoning is a small but potentially lethal risk in commercial and other buildings. It can be a result of a malfunction in many common devices, from central heating systems to cooking appliances.

Carbon monoxide is often referred to as a ‘silent killer’ as it is odourless and impossible to detect without carbon monoxide monitors, so it is important to install these in your workplace. Here at Seton, we offer a wide range of detectors that will alert workers to the presence of carbon monoxide.

How to Choose a Carbon Monoxide Detector


Carbon monoxide (CO) is extremely dangerous, it is an odourless gas that also cannot be seen, so it is very important to make sure that carbon monoxide detectors are working well and have active batteries.

Around 50 people die every year from CO poisoning (ONS 2015) caused by gas, oil and solid fuel appliances and flues that have not been properly installed, maintained or that are poorly ventilated.

Thankfully, it is simple to avoid this potentially life threatening risk. Maximise your protection by installing carbon monoxide detectors in vital areas of you home and workplace.

Where to install carbon monoxide detectors?

Ideally every level of your building will have a carbon monoxide detector installed, consider these suggestions before you buy:

They get the best readings when placed five feet from the ground
  • In residential homes they should be placed near sleeping areas

  • Near garages attached to buildings

  • 1 and 3 metres from any potential source of CO

  • Rooms where people spend a lot of time, living room, kitchen etc

  • In rooms with any fuel burning appliances, but not directly above them


There are also some places where it is not appropriate to install a carbon monoxide detector, they include:

  • In small enclosed spaces

  • In humid areas such as a bathroom or above a sink

  • Wherever there is direct sunlight

  • Near open windows, vents or fans. This is because it could dilute the carbon monoxide making it difficult to detect


How long does a carbon monoxide detector last?

This depends on the detector, there are several types of carbon monoxide detector available with different power options, which will determine its longevity.

Sealed in battery units, such as our Radio Linked Carbon Monoxide Alarm are ideal for use in places that will not be easily accessible or where the ability to check the device regularly will be unavailable. These self-sufficient units can have a life span of up to 10 years, and will give a warning sound when the battery is near depletion. These units generally have a higher entry price point but due to their longevity are a better investment over time.

Battery powered carbon monoxide detectors. These are great for use in residential areas and have a lower cost. Batteries for these units usually last for 2-3 years at which time they will need to be replaced. It is best to install these in areas that are easily accessible and where maintenance can be performed as needed.

The maximum a carbon monoxide alarm will be operational is for 10 years.
