Carbon Monoxide Detectors & Alarms

Looking for a carbon monoxide alarm? At Toolstation, we stock life-saving carbon monoxide detectors to monitor CO levels from trusted brands Aico and FireAngel.

Choose from a range of trade quality carbon monoxide alarms, including the FireAngel digital carbon monoxide alarm CO9D with a 7-year sealed in battery and LED screen, and the FireAngel 7-year life carbon monoxide alarm CO-9X with an advanced electrochemical sensor.

We stock mains powered, battery powered or wireless carbon monoxide alarms. You can also find dual FireAngel carbon monoxide alarms that are combined with a smoke alarm.

If you are looking for a smaller carbon monoxide detector, opt for the FireAngel carbon monoxide alarm TCO-9B. This model is popular for being small and un-obtrusive. If you are purchasing more than one CO detector, save money with our FireAngel twin pack.

Monitor CO levels with our range of Aico CO alarms, these carbon monoxide detectors include a lithium battery and a memory feature to show the last recorded CO level. They also feature test/silence buttons and fault indicator alarms.

For safe and effective use, carbon monoxide alarms should be installed, checked and serviced according to the manufacturer’s instructions.
