You will also need to be in possession of a shiney new Medical Certificate available from your friendly Aviation Medical examiner at a cost of anything between £100 and £200. Or failing that if you are going for a NPPL then get your GP to sign a form for free (if you are lucky, as I was!)
Thom book 2 (Air Law) is also necessary together with a copy of the PPL Confuser..........and then there is book 3.......etc..
Maybe a visit to your friendly bank manager should be the first thing so that you have the dosh to pay for this habit.
I was once told "aviation is like a coke habit only you meet nicer people"
