Ok, so if you want to please the UK CAA, then go ahead and do everything in your island.
Again, if you believe that you will find an airline that does not fly to Europe nor Ireland nor elsewhere, and this is what you want, go and do all your training in the UK.
Very strange advice indeed. Happy to see that you want to go abroad for part of your training for the experience, so take the advice of people who have been outside the UK and dealt with other CAAs and get yourself an ICAO PPL.
You write that it is not only a money issue, so if you spend the same money on an FAA PPL, you will see that it is a good licence to have: it does not expire, includes the night qualification, and s yours to keep, while you loose your JAR PPL upon gaining the JAR CPL. A lot quicker too due to weather and other issues.
good luck! IP
