The Importance of Carbon Monoxide Alarms for Landlords


As a landlord, ensuring the safety and well-being of your tenants is paramount. One crucial aspect of this responsibility is protecting them from the silent killer: carbon monoxide (CO).

From the 1st of October 2022, legislation mandates the installation of carbon monoxide alarms in all habitable rooms of rental properties containing gas appliances, excluding those used solely for cooking purposes.

Let’s delve into why these alarms are essential and how landlords can ensure compliance and safety for their tenants.

Why are Carbon Monoxide Alarms Necessary?

Carbon monoxide is a colourless, odorless gas produced by the incomplete combustion of fuels such as gas, oil, coal, and wood.

Known as the silent killer, it can be fatal if inhaled in high concentrations. Because it’s undetectable by human senses, carbon monoxide poisoning often goes unnoticed until symptoms appear (such as headaches, dizziness, nausea, confusion, chest and muscle pain as well as shortness of breath; according to the NHS), which can mimic common illnesses. In severe cases, it can lead to unconsciousness and death.

Given the serious risks associated with carbon monoxide exposure, installing alarms is crucial for early detection and warning.

By alerting tenants to the presence of carbon monoxide, alarms provide valuable time for evacuation and intervention, potentially saving lives.

Legal Requirements and Responsibilities

The law now mandates that landlords install carbon monoxide alarms in all habitable rooms containing gas appliances.

The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 states a carbon monoxide alarm should be equipped in any room used as living accommodation (rooms where tenants spend time for living, sleeping, or general use), which contains a fixed combustion appliance (excluding gas cookers).

Additionally, landlords must perform checks and tests to ensure alarms are in working order on the day a new tenancy begins.

Adhering to these regulations not only fulfills legal obligations but also demonstrates a commitment to tenant safety.

Failure to comply with these requirements can result in hefty fines (up to £5,000) and, more importantly, put tenants at risk of carbon monoxide poisoning.

Choosing the Right Carbon Monoxide Alarm

When selecting carbon monoxide alarms for rental properties, landlords must prioritise quality and compliance.

Look for alarms that comply with British Standard EN 50291 and bear British or European approval marks, such as the Kitemark. These standards ensure that alarms meet rigorous safety and performance criteria, offering reliable protection for tenants.

Additionally, landlords should follow manufacturers’ recommendations for installation and testing to ensure alarms function correctly. Your local fire and rescue authority may be able to provide further advice on installation or you can download fire safety information from

Regular maintenance, including battery checks and replacement as needed, is essential to keep alarms operational at all times.
