Best to go to a nearby fruit specialist and put your cards on the
table. Your high rainfall will be a factor, as well as how much
direct sun the trees will get.

I've done a quick Ggl, and found, among others:

http://www.england-in-particular.info/corn(orc).html
http://www.cornwall.gov.uk/Environme...s/ab-de03r.htm
both of which list nurseries and give general information.

Just at random I picked the following nursery between Helston and
Penzance, but they aren't specialists:

The Duchy of Cornwall Nursery is at Lostwithiel, and is likely to be
very good (well, HRH is commendably fussy about these things, and I
like his biscuits!):
