A WORD OF WARNING
It is a misconception that a ramonage/chimney sweep only needs to be done once a year. A ramonage must be cleaned in accordance with the RSDT regulations (It will more than likely be in the small print of your insurance) for wood, coal burning or fuel generator this is TWO TIMES A YEAR. For Gas appliances, it is once a year. It could be an expensive mistake to make if you were unfortunate enough to have a Chimney Fire.
