How often should a chimney be swept?

How often should a chimney be swept?

By the Logcroft team · Last checked 21 October 2026

Fire and carbon monoxide: Fit a working carbon monoxide alarm in the room with your stove and test it regularly, have your chimney swept, and burn only dry, untreated wood or approved fuel. If your alarm sounds, open windows, let the fire die down, get out and call the Gas Emergency or a professional. In a chimney fire, call 999.
