The manufacturers of certain appliances can recommend specific fuels for use with their products and this is the one you should use. If you do not know what the recommendations are there are some things that should be to be taken into consideration. As a ‘general’ fuel Oxford Chimney Sweeps recommends wood. It is carbon neutral, clean and gives off excellent amounts of heat. However, at the end of the day, some people don’t get on with wood and find coal is a much better option. If you are looking at coal, find your local approved supplier who will have the expert knowledge to guide you.

Why do I need to get the chimney swept before it is closed off?

When a chimney is closed off it can get damp. If it has not been cleaned prior to closure then there could be soot left in situ which can turn into a black acidic slurry that often soaks into the internal walls causing severe problems. If severe enough this damp slurry can penetrate through to the adjacent room where it will cause unsightly stains stains on the walls.
