I have no reason to believe a sparky went in there, all a sparky did was
fit an electric shower, switching off the master switch on the fusebox
inside the house would have sufficed.

Well the sparks would need to see what sort of supply it was if he was
going
to fill in an electrical installation certificate for the shower.

What information could he possibly get from the meter box that would be
applicable to installing a shower? Everything he needs to connect to is
in the consumer unit, and labelled for him.

Let's see.

Type of supply (ie earthing arrangements), number and type of live
conductors, details of protective device.

More than you think.
