OK now I understand how two 'stats
work - thanks. What a helpful Dr Evil you
are!.

When using the multi-point have
the store temp 75C to avoid condensation
inside the multi-point. .

This may well be sound advice... however
by design mains water into this
boiler (sorry water heater) would be stone
cold anyway?.

True, but don't help it along when you can avoid it. The innards are pretty
rustproof.

Thanks all for your input, I think I've got enough now to be going on
with.
I'll be spending the next week or two doing the bread&butter stuff of
installing radiator circuits, by which time I should hear back from the
LC.
With the pumps + immersion (new circuit) to install, I'll probably raise a
part P building notice anyway (or was there some dodge involving 3 pin
plugs?).

I think there was. Wire the lot up using a terminal box. Have "all"
components: cyl stats, programmers/stats, pumps, boiler, etc into the box.
Then take a flex to a 3-pin plug.
