I would take a serious look at Tom Sands. He's not currently working in the UK (he's studying as Ervin Somogyi's apprentice in California) but is due to return soon. I work with Tom and can tell you that his work is expertly executed, original and very pleasing on the eyes. His guitars also sound fantastic as an added bonus
You can find some examples of his work here:
