Would also recommend Chris Caines at C&S Aviation, I have flown with him many times and not only an excellent instructor but a fair and patient examiner.
Also highly recommended is Dave Coulson at Cranfield Aero Club. Whilst unconventional in his instructional techniques he has an absolute wealth of knowledge & experience which he is willing to pass on. He also won't ask for a penny up front.
Enjoy, where ever you do it!
