We are in process of replacing the roof and windows to our Wicks conservatory. There seems no problem in finding people to do the work.(no longer under guarantee though) Summerville glass Reading, Abbey conservatories and Earley Glass. Abbey quote is the most expensive so far.I'm sure they will travel. Problem we have is we have etched glass in the windows and they have nearly all blown. This is now very expensive to replace. They can take them apart and clean but some are badley stained and may not clean up. Hope this helps.
