If a school claims to offer JAR training, ask them which State's Authority has approved them to offer this training. If it's anyone other than the UK, then, as it said in the link which Reddo provided right at the top of the thread, the training can not be combined with theory exams from a UK school.
If they claim to have been approved by the UK CAA, but they are not listed in the document which I've given the reference to, ask to see a copy of their certificate, and call the CAA to confirm that it's valid. The most likely explaination is that they're not being entirely honest with you - e.g. maybe they're applying for authorisation but haven't been granted it yet. Another explaination is that the CAA are slow to update the document with newly-authorised schools.
(I'm not implying that any of the schools you list are necessarilly being dishonest with you. I have no experience or knowledge of any of them, nor of their authorisation status.)
Hope that helps,
FFF
