We currently do groundschool in the first 2 weeks of every month in Prestwick. Note that the ATPL(H) exams are going bi-monthly for Glasgow. You may want to look at AST in Perth - they just got approval for ATPL(A) but I'm not sure if that is residential or not.
As for classroom stuff - I think you will find Bristol's notes good enough not to necessarily need the classroom, aside from making sure you are away from distractions, etc. We find most people do better than they think on distance learning.
