In the UK for a full PPL you're looking around the £5000 mark, I haven't got a clue for Spain. I don't think there will be a lot in it with the current Euro exchange rate.
If you're based in Kilburn (I'm from Belper, although don't live there now) you only have Derby Aero Club or Hucknall to choose from. Do a google search, call them and see what they can do for you.
Hope this helps and good luck
