In reply to CHarrison:
According to my sat nav Sheffield is 1h 40 away, so if you could stretch to that then the world is your lobster.
Much closer though is Pinnacle at Northampton, which I find to be a really friendly wall with some good routes for the size of the venue, although the bouldering is a bit limited.
Or Big Rock at Milton Keynes, the bouldering there is quite good, although it's very hot in the warm weather.
I haven't been but there's a Depot in Nottingham too.
Also a place called Wolf Wall I think, in Wolverhampton, I've never been but maybe worth a look.
Got luck.
