Mr. Wednesday (guess by your handle and location) ;-)
I had LASIK surgery about 2.5 years ago. One of the best things I've ever done. It has made a massive difference to my view of the world.
Read the Internet newsgroups to get feedback. You will generally get the bad results being reported, and some of the horror stories are terrible. But I've got no qualms recommending the company who did my eyes they were professional all the way and not too far from where you are located (Leeds).
Although I have better than 20/20 vision today I'm still not worthy of a Class I certificate as the CAA deem the pre-op prescription as the one to use. C'est la vie.
