Does he just make all his connections, then contact supply co. to come
and make the final earth connection?

Yes, provided the supply company has agreed to provide one. Otherwise, it is
earth rod and 100mA time delay RCD time.

He had one go a while back, but couldn't get them to talk any sense.

He explained (or tried to) what he was planning on doing, and any
specific requirements etc. from them, but all the person he spoke to
could do was witter on about getting an electrician in, that the
electric's in the house were nothing to do with them. I don't think they
really understood what he as talking about.
