Land in the UK is an odd thing. If you can't do anything with it then it's not worth anything really, just what someone is willing to pay. I bought the mews (in NW6) on which my house stands for £7500, and a neighbour bought a stretch of driveway for £5000.
If it is development land - i.e. it can have planning permission then it would be more valuable, and there may be more local examples to help you arrive at a price, but again really its up to you and the seller to agree a price you're both happy with.
