I am the Avon based breeder, and know of a litter just born in Leicestershire. I think the Midlands is about as near as you are likely to get any time soon. :D
I have had a pup travel with no trouble on a 12 hour journey to SCotland, and a 30 hour flight to Australia. Most pups travel OK, especially if they have not been fed before the journey and are sleepy.
If you did as my owners did and collected pup on the evening and drove over night, the pup would more than likely sleep all the way, and the Midlands are that bit closer anyway.
Sadly there are now hardly any breeders in Scotland

PS Edited to add that the sister of the litter just born had pups last year, one of which travelled to Scotland with no trouble at all.
