There is no specific 'IF module' for the PPL course, whereas in fact for the NPPL course we require 1 hour - enough for pilots to realise that they should stay out of IMC!
PPL training will count towards the NPPL in full and the exams are identical. The only NPPL-specific item, if I recall correctly, is operation from grass runways.
If you fly a PPL QX-C rather than an NPPL QX-C, it will susbequently count towards PPL requirements as well - unless the €urocrats have screwed things up....
