Why should I have my chimney swept
You should have your chimney/ flue swept at least once a year to remove the build up of soot, creosote and tar to reduce the risk of chimney fire, and in some cases to validate your buildings insurance.
The sweep will check and remove any blockages caused by birds nesting or building debris, even cobwebs in a pre cast flue thus eliminating smoke and harmful gases re-entering the room. These gases could be fatal in the form of carbon monoxide poisoning, the silent and odourless killer.
The table below shows how often your chimney should be swept depending on what fuel you use.
