The new headline speed represents an increase of 50 Mbps with those on the VIVID 300 being transferred to VIVID 300 at no additional cost.
The download of a standard HD movie file of 5 GB should be completed in around two minutes, compared to more than 16 minutes on the UK’s average local connection of 44 Mbps.
Anthony Vollmer, executive director for connectivity at Virgin Media, said: “We’ve always been proud of our network’s speed and for good reason. Our lines bring blazingly fast download speeds which are leagues ahead of those our customers could find elsewhere. We have been the speed leader since 2007: We intend to remain at the front of the pack.”
Virgin claims the 350Mbps service up to four times as fast as Sky and BT’s fastest widely available speeds.
