A personal recomendation for
On Track Aviation. It's a little way from you, but for me they stood out so much they were well worth the commute. (I was living in Slough at the time, so not too far from where you are.) The thing which really stood out for me was that rather than being a PPL school with one instructor who runs an FIC course on the side, which is what most places offer the prospective instructor, these guys specialise in FIC training.
I have no connection with them except as a satisfied customer.
