Carbon Monoxide Alarms are a basic but necessary safety feature in any home using fuel-burning appliances. Carbon monoxide is invisible and has no smell, which means exposure can go unnoticed until symptoms appear. Correct installation, regular testing, and timely replacement of alarms reduce the risk to you and your family.
Where to Install Carbon Monoxide Alarms
Install Carbon Monoxide Alarms in suitable locations for reliable detection.
-
Fit at least one alarm on each level of your home
-
Install alarms near bedrooms, so alerts can be heard at night
-
Place alarms 1–3 metres from fuel-burning appliances
-
Install at ceiling height for wall-mounted units, or follow manufacturer guidance
Avoid placing alarms:
-
Directly above cookers or boilers
-
In bathrooms or high-humidity areas
-
Near windows, vents, or extractor fans
Poor placement can lead to delayed alerts or false alarms.
How to Test Carbon Monoxide Alarms
Regular testing keeps Carbon Monoxide Alarms functioning correctly.
-
Test alarms once a month using the test button
-
Test after changing batteries
-
Test before winter, when heating systems are in regular use
-
Test again after returning from extended time away
Never test alarms using naked flames, vehicle exhausts, or gas appliances.
Battery Care and Alarm Lifespan
Battery and sensor failure are common causes of alarm malfunction.
-
Replace standard batteries once a year
-
Use sealed lithium battery alarms for lower maintenance
-
Replace the full alarm unit every 7–10 years, depending on the model
Most alarms emit warning beeps when batteries are low or the unit has reached expiry.
January is the perfect time to get your household in order and ensure your loved ones and home are safe.
Common Sources of Carbon Monoxide in the Home
Carbon monoxide can be produced by everyday household equipment.
-
Oil, gas, or solid fuel boilers
-
Open fires and stoves
-
Gas cookers and hobs
-
Blocked flues, chimneys, or vents
Annual servicing of appliances and keeping vents clear reduces risk and supports proper alarm operation.
