If you can get to Blackpool, I would strongly recommend Westair, I did my PPL their and I cannot speak highly enough for them.
They've been in aviation for over 60 years, they are very professional and will bend over backwards to help you.
I also use Ravenair on the Isle of Man (in the guise of Manx Flyers) and I have no complaints about them, they have some very good instructors.
