Training towards Stage IV and Intermediate Teaching exam

A few weeks ago I started looking for places where I could regularly go to train towards BHS Stage IV and the Intermediate Teaching exam. The obvious choice, since I live in London, would be Trent Park but I am not too keen on that place for variety of reasons.
I think I found a centre I like and having spoken to someone who works there I am almost sure I might even be able to afford this whole game ;)
