In theory, there is a bridging exam, but the CAA "do not have the facilities" for it. The best step is to get the JAA CPL(H), which in UK requires POF(H) only (check LASORS), then when you have the experience apply for an upgrade based on the fact that you have the IR theory included in your ATPLA (the difference between CPL(H) and ATPL(H) is the IR(H)). I have email confirmation of this, but that was before EARSEA started, so best check with the CAA.
