I'm in a similar boat here.
I have a UK issued PPL and Class 1, and ATPL exams with Austro.
My understanding in my case, if I'm not mistaken, is that after January 2021, you can hold a UK issued PPL alongside an EASA issued CPL, as a PPL must be issued by an ICAO state, and not necessarily an EASA state.
I would like to obtain an EASA CPL (IAA seems a recommended option). So my CPL SOLI would need to be Ireland.
It's my understanding however, that your licence and medical details need to be held by the same EASA state.
Would it be advised for me to therefore change my PPL SOLI to Ireland, transferring my medical in preparation for an Irish CPL, or should I just hang fire with a UK PPL safe in the knowledge I can obtain an EASA CPL on top of this??
If somebody could confirm I'm understanding things correctly, and give me an answer to the above question it would be greatly appreciated. I've spent a long time wading through info trying to make sense of it all!!
