The Cople web site receives a lot of junk e-mail shots asking me to give them a free mention of their wonderful product. Most go straight into the bin. But I have just had one that makes a little sense and told me things I did not know.
There is a trade association for chimney sweeps, NACS, who, obviously, campaign for everyone to have their chimneys regularly cleaned. So far no surprises. But they go onto say that if a chimney is not regularly swept and a certificate issued then your insurance company may refuse to pay out if it catches fire. I don’t know if this is true but worth thinking about.
They also have a list of how often a regular user should have it swept, and this includes a gas fire chimney.
Make your own minds up, more information on their web site nacs.org.uk
