When I was an apprentice in the late 70s early 80s it was a busy time for us as all of a sudden people wanted to have there houses upgraded with ring mains. Most of the time it was not economical to just retire the sockets so we often done the whole house .in those days I would say about 70% of the time we would be doing surface drops only hiding cables under the floor.. customers didn’t want there walls chopping out.
We had one customer insist that everything was surface, not going into lofts or taking floors up . Saying cables should show for safety reasons. Mind you using buckle clips did look very neat if you brought cables down in the corners .
It’s very rare these days but I still very occasionally use them Andy
