Widespread lack of carbon monoxide alarms in UK homes

A survey conducted by Firechief Global has revealed that 42% of homes in the UK do not have a carbon monoxide (CO) alarm installed, equating to over one in three homes.

According to Firechief Global’s Managing Director, Laurie Pollard, carbon monoxide poisoning is a serious threat: “Having carbon monoxide alarms fitted throughout your home is not just an optional safety precaution, it’s a lifesaver.”

Statistics show that around 40 people die annually from accidental CO poisoning in England and Wales, with 440 major injuries requiring hospitalisation and approximately 4,000 emergency department visits in England alone.

Experts believe the actual figures may be higher due to misdiagnosis and underreporting.

Regulations on carbon monoxide alarms

In October 2022, UK regulations were amended to mandate the installation of CO alarms in rooms with fixed combustion appliances, excluding gas cookers, in new builds and rental properties.

Landlords are required to replace or repair faulty alarms and check their condition before a tenancy begins.

Local housing authorities enforce these regulations in rental properties.

Pollard advocates for extending these regulations: “Extending the regulations to include existing homes is a crucial step the government needs to take in protecting everyone from the dangers of carbon monoxide poisoning.

“The data shows that voluntary recommendations are not sufficient.”

The estimated cost for installing additional CO alarms is £27 per unit, with the price expected to decrease over time, according to the UK government.

How to fit your carbon monoxide alarm

Pollard outlines the steps for installing CO alarms: “It’s easier and safer to have your carbon monoxide alarm fitted by a professional who can ensure your alarm is compliant with the regulations and installed in all the right locations.

“However, that doesn’t mean you can’t opt for a DIY installation.”

CO alarms should be placed 1-3 metres from potential CO sources and at head height.

They should be installed in rooms with fixed combustion appliances and near sleeping areas, with at least one alarm on every home level.

Pollard recommends: “For battery-powered CO alarms, ‘sealed for life’ batteries are preferred over replaceable ones to prevent tampering.

Mains-powered alarms with battery backup are even safer, though they require professional installation.

Ensure your CO alarm meets British Standard BS 50291-1:2018.”

Best practice for testing your CO alarm

Regular testing is essential to ensure CO alarms function correctly.

Pollard advises: “Test your carbon monoxide alarm every month. Press the test button until the alarm sounds to confirm it’s operational.”

Check the indicator lights: a green light means normal operation, while a red light or audible alarm indicates a problem.

Follow the manufacturer’s instructions for specific models.

Non-sealed battery-powered alarms should have their batteries replaced at least once a year.
