brickwork, there is no outer layer of brick/blockwork - there doesnt
look room for it under slope of roof. This means, that inside the
first floor rooms, the brickwork over the windows - about 300mm high -
is only one layer thick, which is probably why it seems to create cold
surfaces of condensation, etc. Am I right in this conclusion, and is
there any way to help insulate the area over the windows? Advice much
appreciated.

My house is the same - about 300mm of blockwork above the window on the inside, the top of the window is level with the soffitt on the outside. When I had new windows put in there was just a gap above the window frame into the loft above. The window frame pretty much filled this, with a piece of quadrant/sealer around the top, & sides. Never really thought about the heat loss consequences of this, but i've never had any problems with condensation or anything.
