For the current CPL(H), you will need to pass 9 exams. This is being renamed later this year to the ATPL(H)(VFR), and the CPL(H) replacing it will be around the same lowish academic standard as the current CPL(A). Currently, the only essential difference between the CPL and ATPL are the amount of hours you have and the IR studies.
Dragon, Atlantic and A N Other that is getting approval this week or next week all do CPL(H) distance learning courses. Only the A N Other will do ATPL(H)
