BEagle, those prices might be "way out of date" outside with civvy flying clubs but take a look at the prices of a SE(P) with instructor at Waddington or Halton Flying Clubs (or others) and they charge about £100 all in per instructed flying hour in a C152. Looking at Halton's website they charge £15 per CAA exam.
Training at Waddo is in four seaters (172 or 28) and with the ground exams, maps and other bits and bobs an EASA PPL will now cost you around 6K if you do it in min hours. However you can offset your ELCAS against this which makes getting a PPL for a serviceman stupidly cheap, don't know why more don't do it.
