STS 122 launched yesterday on time (to my surprise after the weather forecast), and will, with the space station be visible over the UK.
This evening (8th) the ISS will pass overhead at about 17:55 (and later at 19:25), and the space shuttle will probably be between 10 and 20 minutes behind it.
Tomorrow (9th) the shuttle will be docking with the space station, I haven't been able to find out at what time, but if they haven't already docked by tomorrow evening they will be much closer in the sky, hopefully only a few seconds apart or less. It'll pass overhead at about 18:15.
To get exact times check Heavens Above. Be a tad sceptical with the times listed for the space shuttle as it is changing its orbit gradually which can often throw the numbers out.
