Lining a chimney...
Discussion
You need to establish whether you are proposing to line the chimney purley to make it smoke proof or for structural integrity. If the chimney has deteriorated to such an axtent that the mortar is falling out of the joints then you'll need something more substantial, such as: http://www.thermocrete.com/the_process.htm
Scaffolding or cherrypicker hire may come into the cost, a lot of fitters aren't insured to work on the roof without something like that. Get an NACS registered chimney sweep to do a proper examination if you want a second opinion. The materials are usually priced by the meter, on average you'll need between 8-10 meters. Roughly it'll cost £1000 including fitting, plus whatever stove you want, if you do it properly.

If you use a woodburner most of the time, you'll probably need the chimney swept twice a year. It can help to regularly use a smokeless fuel like Extraheat or Phurnacite instead of wood and let the stove have a good blast. It runs hotter and can help to clear some tar out. Unless you have a cheap supply of wood it can be cheaper and more convenient to use a smokeless fuel. It burns for ages, puts out more heat and is much cleaner than wood in terms of crap in the chimney. Not so good for you carbon footprint though!

Chimey fires are extremely common - my father was a firefighter and probably half of all their call-outs were fires, mostly where material built up in the chimney was curning. The odd few caught rooves or the whole house alight too - due to gaps/cracks in the mortar. If you are burning a lot of wood (ie. more than an open wood fire once a week) in a chimney that has mostly been used for coal then I would say lining is worth doing.
Or getting it swept every year.Edited by g_attrill on Saturday 4th April 07:37
I wonder how many people never get there's done?
Come next winter and there is an incredible smell of burning plastic, and the chimney breast in the bathroom was red hot....That would be the chimney brush then.....
We just let it burn out and it was fine - haven't swept it since, and that was a good 8 years ago now, last year opened up the gable end to put an inspection plate in and the chimney looked spot on, they knew how to build them in the 17th Century.
I should add, that our roof purlins DO NOT enter the chimney breast, if yours do, get it swept!
