The STUDIES can be undertaken anywhere - because it's self study from the books that you buy.
The EXAMS at the end of the study - try calling PTC at Waterford (I've no idea of the number) - they have satellite approval through a Bournemouth school, it's quite possible that they have a set of PPL papers.
Note: For professional licences you can do one JAA state written exams and another states flying training. For PPL you CANNOT - so make sure the papers are UK CAA PPL papers.
