It's the use of the word "plug". That to me is the thing on the end of a
cable that is designed to be detached from a "socket". The earth should be

That's me not being technical enough... it does indeed go into a
double socket - well and truly attached to the wall!

That doesn't sound right to me, usually it would go back to either the
consumer unit (fusebox) or a connection block near it.

Can you post a picture of the whole fusebox arrangement inside,
including the cables to/from the meter?
