As you are looking for a school in the south of England then I could recommend Flightpass in exeter. Just been through the FI rating with them and if i had my time again would have gone with them for the CPL as well. I found them to be an excellent bunch of people who made you feel welcome and the training was top class. Feel free to PM me if you want any further details or give there web site the once over
