We're about to replace our open fire with a woodburning stove.
The stove shop says we should line the chimney with a flue liner, to prevent fires.
The chimney sweep (who's also a stove fitter) says that stove shops say this because they make a big profit on liners, and that we don't need a liner.
Does anyone here have any knowledge / experience of this?
The chimney is comparatively modern, but I don't know whether it was built after the crucial date of 1966 which is apparently when the regulations on chimneys changed!
