Recommend solder wick in Uk

A better (but costlier) alternative is to use the silvered braid of a coaxial you just stripped (be sure to strip it only when you need it): it acts as a real solder magnet, much more effective than "official" wick.
You need to wet it with a very small amount of flux (easily available), and that's it.
For intensive desoldering, it would be expensive, but for the odd, single need it is perfect
 
I've used Servisol Soldamop ( available from Farnell ) for decades. It's effective and has a very long shelf life. A 10m roll lasts me for a few years. I always use it on large blobs of solder which would otherwise block my desoldering gun.
