In the cupboard under the stairs, I can either move the suppliers
meter board (am I allowed to do that? would they know? ;-) ) to make
room for the new consumer unit next to it (won't fit on it, even if
that was allowed), or put the consumer unit on the adjacent wall.

If I put it in the adjacent wall, it's sitting right above the pipe
bringing the water into the house, i.e. right above the stopcock. Some
of the cables might have to run behind the pipework which loops out of
the stopcock and back under the floorboards.

I don't like either option, but which is least bad?

Is either one (or both) disallowed by regs? I don't think I'm supposed
to move the meter board, but I don't think I like the idea of having
the stopcock below the consumer unit. It can't leak upwards, but I
suppose it could spray upwards if something catastrophic or stupid
happened.

Cheers,
David.
