I have about 100 peach trees, be aware that peach trees need hot sunny days to ripen so dont expect too much out of them in England, If there are not hot sunny days the fruit may swell but not be sweet or ripen, there are 1 or 2 that need another peach tree to fertilize. But most will fertilize them selves.
My only advise would be to plant it in a hot sunny position, and get the next door neighbor to prune it (as we say around here, if you are new to it, you may leave too many buds on in the spring pruning lol they need hard pruning) the flower buds are susceptible to late frosts. the buds can be open ie: no pink showing through, but still burst, you should be ok if a bad frost hits you, if the flower bud opens ie:you can see pink and you get a bad frost check by splitting a flower open and seeing if it is black in the middle after a couple of days. If its still pink or green chances are you should be ok.
