For PPL training, Thruxton are good as previously suggested I must also reccomend Solent Flight based between Winchester and Southampton with some a/c based at Bournemouth. From personal experence they are excellent with a variaty for aircraft from VLA'a to all singing PA28's fully Garmin equiped, their CFI is a Flybe Training Capt and a great bloke. It is run by a guy called Andy who will go out of his way to help anyone get flying. I am sure they will also offer some excellent hour building packages if that is what you are interested in. They offered me a great package on a variety of aircraft some flights with instructors to keep me progressing and setting targets to achieve in prep for CPL, unfortunalty due to family issues I was not able to take them up on their excellent offer.
If you are looking at CPL/IR I would look at BCFT and PAT in the big B'mouth.
Hope this helps
