Hi,
I have also heard from a few friends that have been out there and gained various ratings, that BFC is a great place.
If you do a search on Britannia Flight Centre, there are plenty of threads about them, a lot of good one's, probably a few bad one's as well.
I have been in touch with them a few times, by email and phone, and i have chosen to go with them to do my PPL in September.
The one thing that i have been told is try and do the majority of your exams before you go as the training is quite intense
I hope that this helps!
