I've now been advised that because of the size of the flat roof needing replacement, building control will require that the roof have additional insulation to meet part L. What do you think would the likely cost be of incorporating a decent insulation layer over an area of 40 sq mtrs?
I've already had quotes for doing the boarding and refelting over the area, but I want to have an idea of the extra costs before I start getting revised quotes, as the process seems to take so long.
Thanks for any help.
