Teddy,
If you do your PPL at Leeds it will be with Multiflight. They have an introductory night once a month I think, have a look on there website for the next meeting, go along and have a chat. I reckon you'll be looking at £8k if you do it at Leeds.
If you go to Sherburn or Full Sutton you'll be looking at around £6.5 - 7k, thats what mine cost at Sherbs. You'll take around 50 hours to get your poo brown wallet. It really is as good as everyone says it is.
