we just used RPS fireplaces to fit a stove we bought direct on-line. Was miles cheaper than the shop quotes who all insisted on lining our chimney - an unnecessary job which added ?1k to the cost! We used Paul Silver 07939236261 and he and his partner worked really hard all day to give a good result. Nice guys - got their details via this forum in the first place. Also used their recommended sweep Steve Pearce 07930345245.
