Although I'm in Cornwall, I'm 5 miles inland, 500' East facing elevation -
we get the same winters as Dartmoor. Last year I lost a couple of 2 year old
cherry trees and I think our 7 year old Wisteria may have perished.
It started to produce buds during the warm March, but now the frost has
blackened them and these buds about 4mm long and are seriously dead.
Q1 Will they form new buds this year, or can I assume the Wisteria is dead?
If yes, it's a great pity, as it produced a fine display from year 3
onwards:-

Are all the buds black (flower and leaves)? Frost won't damage wisteria
buds - they are very hardy. But if yours is grafted (as many are), it
is possible that water got into the graft, froze, expanded, and split
away the scion from the stock. Graft failure in wisteria is not uncommon.

If it has happened, it is very likely the scion has died. But it's
always worth waiting a year or two to see what happens. If you get a
strong regrowth from underground, it will be the stock plant. It will
flower eventually, but you will have to decide if the stock flowers are
worth the wait!
