Nope.

So long as they don't exceed the powers granted to them by the
privatisiation
legislation, they're as allowed to be as selective as they wish, in which
particular
provisions they choose to enact.

As far as I know the only things that are banned are washing the
car with a hosepipe, and watering the garden. If you've a pointer
to a legal resource that says different, I'd like to read it, for
interest.
