Caution! It's open to anyone to prove otherwise, but I don't see any sign that they are Approved under Part 147, and you could waste a lot of money there. I would want to check exactly what they mean by
There is the possibility to undertake component modules of the B1 Licence on completion of your course.
which does NOT say that they offer these examinations; perhaps they just mean you can toddle off to the CAA and sit their exams.
What's more I don't see anything which says that they teach the EASA Part 66 syllabus, no more and no less.
And where are the "apprenticeships"?
Maybe it's all bona fide and so on. But you should be very careful indeed to check it all out. Their website gives me no confidence at all.
