Get your chimney swept regularly. Your insurance company expects you to get it sweep on at least an annual basis. They can turn down a chimney related claim if it appears you haven't taken due care to look after your chimney. An annual chimney sweep with the Happy Chimney Company will issue you with a insurance approved certificate AND we will cctv inspect the condition of the inside.
Ensure your chimney is swept once a year if you’re burning smokeless coal
