The ones I've seen were generally quite ok. Highly structured and all installed to a high standard.
The fuse boxes were always Diazed never re-wirable. Nice little panels that fitted neatly into the plasterwork with a door on the front. These were the "posher" houses occupied by the snootier members of society so they had to look the part.
The fittings were usually nice brass tumbler switches mounted on carved teak plinths and the sucho sockets were recessed into similar plinths.
Usually 5/10 amp.. 16 amp was relatively rare other than for specific items like kettles, washing machines etc.
