Perhaps the switch location has a dual role: up/on = occupied, down/off =
unoccupied?

That must explain the bathroom light switches in my house here in New
Hampshire, they all are on the outside wall instead of the inside. Maybe we
had a UK trained electrician!

It is a lot safer. They use isolation transformers and 115V on building
sites in the UK.
UK code will not allow light switches in a bathroom. It either has to be a
string pull switch in the bathroom or a wall switch on the wall outside
the
bathroom. There are no 240V power sockets allowed in the bathroom apart
from
transformer isolated razor outlets.
Lots of people in the UK die using 240V electric mowers and cutters
outside.
It isn't 120 0 120 like here. It is 240Vrms relative to the Neutral/Ground
potential. That is 660V pk to pk relative to ground. You take a shock and
it
really hurts if it doesn't kill you.
