Classair at Biggin Hill, you will not go wrong.
Iris the owner does this for the love of flying, she is therefore cheap in comparison. The price does not have any add-ons, vat, landings,touch and go, exams, circuits all included. Very friendly place to learn.
Biggin is a good airport to fly from as once flown fron a large airport you can fly anywhere. Going from a small grass airstrip to a large airport can be chalanging for a novice. The other way round easy so long as you touch down at the beginning, before anyone picks me up on that.
