Or do an NPPL SLMG 32 hours I think , then do differences training for NPPL SSEA no minimum hours requirement and no further exams to sit as you have already done them and the 1 hr instrument appreciation. Typically 3-5 hours training but could be done in a couple if your good.
Then NPPL to EASA LAPL if you want, your then in the EASA system.
I know someone who did it with on the minimum hours and minimum cost about £3400. Not bad for an NPPL SSEA. The joke is the charges levied by the CAA.
