Hi Shaun,
The cost quoted is probably for 45 hours' training, and will not include things like landing fees, exam fees, books and other materials. When I started my PPL training I couldn't really find any information on costing either, but I broke it down here a while back...

In summary, 45 hours training at my school (South Coast) was advertised for around £6100. There's no guarantee that you'll be ready after that time and you might need to pay for more training, but when I took my skills test with 45 hours and 30 minutes in my logbook, with all the additional costs I'd spent close to £9000.
Money well spent though!
Miroku is right though, I was naive paying up front, and if I did it again, I'd pay-as-I went.
