Do I Need to Install a Carbon Monoxide Detector?

01/09/2025 • by Alice P

Your home should be a safe space, and carbon monoxide (CO) is one of the biggest hidden dangers. Unlike fire, you cannot see, smell, or taste CO, yet exposure can be fatal. Our experts at Fire Detection Shop recommend that all homes have a carbon monoxide detector installed.

What is Carbon Monoxide?

Carbon monoxide is a poisonous gas produced when fuels such as gas, oil, coal, or wood do not burn completely.

Because it is invisible and odourless, people often do not realise they are being exposed. Symptoms of CO poisoning include headaches, dizziness, nausea, and shortness of breath. In severe cases, it can kill.

The only reliable way to detect CO is with a carbon monoxide alarm. These devices monitor the air 24/7 and sound an alert if CO is present.

Where to Install Carbon Monoxide Detectors

For maximum protection, install:

One detector in every room with a fuel-burning appliance, such as boilers, fireplaces, or stoves.
At least one detector on each floor of the property.
Detectors outside bedrooms so you can be alerted while asleep.
High on the wall or ceiling, at least 30 cm away from walls or light fittings, as CO mixes with warm air and rises.

Avoid placing detectors directly next to windows, extractor fans, or areas with constant airflow, as this can prevent accurate readings.

How to Test a Carbon Monoxide Detector

Regular testing plays a crucial role in maintaining the quality of a carbon monoxide detector. Testing a carbon monoxide detector is a quick and simple process. It can be done at home without the help of a professional.

Press and hold the test button. The alarm should beep 4 times, pause, then repeat.
Test monthly and replace batteries every 6 months.
Check volume — the alarm must be loud enough to wake you at night.
Clean away dust to avoid false alarms.

Summary

Carbon monoxide detectors are a crucial part of protecting the home. Not only are they a proactive approach to promoting long-lasting home safety but in rental properties they are a legal responsibility.

Carbon monoxide detectors are not a replacement for smoke detectors. However, they are just as important to have installed in the home. Together carbon monoxide alarms and smoke alarms form part of a wider home safety system.
