Just to stick my oar in: I did CPL(H) to CPL(A) and found the regs open to interpretation. Having done it - this could save you a fortune: You don't need 100 hours PIC - all of these hours can be credited helicopter hours. You will need to do the remaining 100 hours in a plane. Obviously PPL 》 multi 》MEIR 》CPL(single engine).
Those 100 hours will easily be enough to cover everything, obviously there will be some Solo/PIC in there for XC etc but you don't need any extra. You may read that you need 70 PIC for the MEP rating. What you won't read is that you don't need an MEP rating in order to get the MEIR.
