I live in South West London so i've been looking at flying schools in and around Surrey mainly. As for the differences in cost it would appear as though the average cost of hourly training is in the region of £160 compared to £130 when i looked into it last time although i appreciate some flying schools add VAT, landing fees etc whilst others don't. I suppose i'm mainly looking for somewhere with a reasonable reputation which doesn't cost an arm and a leg. I looked at one 'leading' FTO in and around the M25 who are charging somewhere in the region of £3000 more for a PPL than many other smaller flying schools.
