or are we talking about a bonding earth cable completely
separate to the SWA sheathing here?

As I understand it, it must be completely separate, not run in the same
cable at all. It has to be pretty thick, too. I can't remember exactly,
but
10mm rings a bell, and it needs mechanical protection for burying, too. If
it gets chopped, it must be relaid end to end, unlike the SWA supply,
which
can use buried junction boxes.

OK, thanks. Separate local earthing arrangements sound like the best and
most straighforward solution all round then.
