There is another thread running on this topic I suggest you look at it, you will find some sound advice there. In the meantime, since you live in England, I would suggest finding out if you have the mental and motor skills to fly before spending too much money.. The cheapest way to do this would be to find your nearest gliding club and sign up for a week's course - normally these run in the summer only, but some clubs do them all the year round. You won't go solo in a week but you will get plenty time with your hands on the controls and you can decide if you are up to this sort of thing. Health warning! I did this and liked gliding so much I never went on to power flying.
