I think i posted on your previous post about this......
Get your UK PPL results , approach a UK Flight school, show them your logbook , they will request your flight training records from the EASA flight school in italy.
Go through a small amount of training and then take your skills test.
The Main reason for your issue is the UK PPL exams are not sat at the CAA in the UK , i presume through a flight school.
The flight training standards are similar to the UK, will depend on your instructors of course.
I really don't understand why you can not get this done.
