A Carbon Monoxide (CO) alarm is the only way to alert residents to the presence of Carbon Monoxide within a property. A CO alarm via an audible alert

Install a CO alarm in every room with a fuel-burning appliance such as a boiler, gas fire, or wood-burning stove. Position it on the ceiling or high on a wall, between 1m and 3m from the CO source. For full coverage, fit one in every bedroom and living area too. See our guide on how many carbon monoxide alarms you need for room-by-room advice.

Carbon Monoxide is produced when fuels burn incompletely – this could be from a boiler, gas fire, oven, log burner or a blocked flue or chimney. It can also travel through walls from adjoining properties, so as well as having an alarm next to appliances in your property we would also advise you to have one in living spaces and bedrooms. To help prevent a Carbon Monoxide leak we advise getting your appliances regularly serviced by reputable engineers who are gas safety registered.

From October 2022, the law changed surrounding carbon monoxide alarms in rented properties – for both the private and social sectors. As a private or social landlord, you will need to ensure you have a working carbon monoxide alarm 1‑3 metres away from any fuel burning appliances in a property (excluding gas cookers) and that any faults or repairs are carried out on the alarm in a timely manner.
