Nildram are great (i've been with them for years now) and they power the Jolt gaming servers which is a pretty good recommendation. Avoid all the big players like AOL/Tiscali/etc.What games are you playing? Speed can be important on some platforms - eg XboxConnect/Xbox Live can only select you as host if you have enough upload bandwidth. Ping is much more important but will only go so low anyway. If you're playing Xbox Live then you'll always lose out to US players as the servers are based stateside, if you live near London then you'll often have a slight advantage over other UK players.
i used to have NTL and it was ace, low ping no issues ever.now its Virgin Media and its fine really, sometimes slow tho and server downtime is a couple of times a month, god knows what for.ive heard sky is good and also the same so low ping and no issues.This is connecting to UK/NL/DE/SWE (central Eu) servers. anything else is useless anyways but this is on call of duty, cs, css mainly
