We have been given a quote for 17k, which seems quite high 
, even given we are in the SE. The conservatory is a lean-to style, about 18x10, with glass wedges at the thin ends, one double door, and not much glass in the uprights (windows start about 4ft up).
We are obviously going to ask for more quotes, but would really appreciate any recommendations/places to avoid/to know if AIBU about the price of the quote? PM me if you don't want to post on here - ta very much!
