From my research before choosing a flight school for a full time course in the UK, I came up with...
Oxford Air training school
Cabair
Bournmouth
Bristol and a smattering of others, Bristol i hear is good.
The first two listed have free seminars every couple of months which you should go to and have a look around. Ignore the anti comments on pprune about flight schools. You will notice Oxford is taking a hammering at the mo, but Cabair will be next month! Go and look around and see what fits YOU best.
