How much does this usually cost (appx)

And also, where to do it? do places like kwikfit do it? or can somebody recommend a place in or around York??

Thanks matt

Not local to you but local to me!
Demon Tweeks set mine up approx 3 yrs ago and it took quite some time to do and the charge was about £50.
