Hi, I both fly from Surrey and Kent and do a bit of ops work for them. They are a great school to learn with, the instructors are probabably some of the most experienced around and are instructing because that is what they want to do for a living (either full time or part time) rather than just to build hours. The aircraft are owned by the club and maintained at Biggin so the 'down time' for things like checks and defect rectification is very short (the owner of the club also owns a maintenance organisation on the airfield). We have got 4 PA28's so even if one is on check there is not normally a problem with getting an aeroplane. We also have a C152 and also operate an Arrow (for once you have got your licence and built a few hours).
There is a nice 'club' atmosphere amongst the members and it is a friendly place to be but a very professional place to learn. I am sure that you would find it a good place to start your flying career.
Did you do your trial flight with Surrey and Kent, if so who did you fly with?
Good luck with it where ever you end up training but do give us a try!!
