I actually did my PPL in the USA (in 17 days) then joined Panshanger hiring their aircraft. Following a quick excursion into Luton's airspace (followed by a phone interview
) I did some "additional" navigation training at Panshanger which taught me what I was supposed to do rather than what I could get away with in the USA.
I went on to do complex differences training there and IMC which were great fun and very good.
It's a great place to learn and understand the airspace in the South East, with Luton Zone to the left and Stansted to the Right and London above.
I'd recommend it, give it a go, if you don't get on you can always try elsewhere.
