There was one in Yorkshire, Castleford I think. It didn't last long. The marginal cost of keeping the wall frozen is probably negligible, so I suspect the reason was staff costs. I doubt there is a large enough base of ice climbers in Yorkshire to sustain it, but they'd have to keep it staffed during opening hours. whether or not anyone turned up.
I visited when it first opened. I had to pay £30 for an hour's assessement, which once I'd shown I knew what I was doing turned into an hour's climbing with a paid belayer. However as it had just opened they had a promotion on, and I came away with a technical T-shirt, RRP £29.99. So an hour's climbing for a net cost of 1p!
