Hi, we are moving into a new property in Doncaster and would like to have a skylight put in to the study. The roof is tiled and the ceiling is flat. I wanted to get a single Velux FS fixed S6 installed with a manual or solar blinds. How much would this cost fully installed? If you need to see the room to give a quote, I have an inspection this Wednesday at 12pm to allow tradespeople to come through to give quotes.
