It's about 60 pounds for the full ticket. I personally don't think it's worth that cost. It's like a 30 minute trip to the top and back down and that's about it. You get a decent view of Westminster and the shard. However, you can get an even better view of London for free by going to the top of the Tate Modern and going to their observation deck.
