Dunno! I wouldn't have thought that Building Control would have allowed

is it part of a large development in which any (minimal) inspection
would have been carried out by the NHBRC?

When I was a BCO (1976-84) it wouldn't have been allowed. It's not
uncommon on older inter-war properties where the frame is made of 4x2
with mullions every two foot or so. My guess is a Catnic or similar steel
lintel - judicious removal of a little plaster on the top reveal next to
the frame should confirm.
