I took a slightly unusual route:
NPPL(M): 32 hours (10 solo) + exams and fees - approx £5000
NPPL(SSEA): £1000
FRTOL: £200 (can't remember exactly to be honest, estimate for book, past papers and exams)
NPPL(SSEA) - LAPL(A): £40 paperwork excersize
LAPL(A) - PPL(A): £2000
In between the NPPL(SSEA) - PPL(A) journey I was flying a PA28 I have a share in so that might make the figures sound a bit low.
Going for my class 1 soon, so all the above will shortly become small change
