Hi Jason
I'm living in North Essex and Studying for my ATPL with Bristol Groundschool. All done from home apart from two, two week, consolidation/mock exam weeks in Bristol. Can recommend, excellent notes/CD-Rom and very helpful staff.
The leaflet from the CAA is entitled as follows:
ORGANISATIONS CONDUCTING CAA AND JAR-FCL APPROVED COURSES OF FLIGHT AND GROUND TRAINING
Good luck whatever school you choose
