Every speedtest I see in that town is at least double that, looks like Virgin offer 50Mbit cable in your area too, judging by the 42.3Mbit/s speedtest someone got : http://www.top10-broadband.co.uk/speedtest/streetstats/#home_whyteleafe_download_0_all_all_3_1

I must be one of the few, too. I'm on the 50mbit service, and getting 50.1Mbit/s and 8ms ping according to speedtest.net. My 20Mbit service before was faultless, and also my 4Mbit service when I lived 90 miles from here (with NTL, before rebranded Virgin), and also my 2Mbit from my flat before that, and also my original 600kbit service in 2000 - and everyone I know on Virgin (and NTL before) has a similar story. (no I don't work for Virgin, just a happy customer)
