Alarms

A CO alarm is not a substitute for a swept flue

Updated 1 September 2026

Fit a BS EN 50291 CO alarm in the room with a fixed solid-fuel appliance. Landlords in England have separate duties to fit and test alarms. An alarm warns you; it does not clean the chimney.

Keep both an alarm and a current sweeping certificate. Landlord notes. Find a registered sweep.
