Helimutt,
Recently I've done exactly what you're trying to do. I had the same request from the ATO to gain clarification from the CAA wrt training required. Thankfully the CAA couldn't have been more helpful - confirming (as already stated here) that it was training as required in order to pass the proficiency check. A couple of flights later and the EASA PPL was fresh off the press.
Hope you enjoy the return to fixed wing as much as I did!
