When I redo my kitchen (again), I'm going to need to bring the mains
water in at a different point, from the outside. Obviously I'm keen
not to have to go under the foundations. Is there an approved way to
bring the mains above ground outside the house, and through the wall,
using insulation, and are there bits of kit made specifically for this
purpose? A desultory Google has brought nothing up.

Well, when I had to lay on mains water from scratch to a do-er upper a
few years ago, I had to jump through the water company's many hoops in
that regard. The pipe had to come in from the street through the wall
of the foundations at a minimum prescribed depth, and be sheathed in
insulation (the preferred way was to use a special purpose-made curved
plastic pipe about 4" diameter, filled with foam insulation). They were
really fussy and came to inspect, demanding further changes before
they'd approve the work. I can't imagine the rules being any different
for what you're proposing.
