More than ten million UK homes can now take advantage of Virgin Media fibre broadband services, the firm has announced.
The broadband provider has launched 100Mb services in cabled areas of Bromley, Dundee, Norton Hawkfield in Somerset, and Staverton in Gloucestershire as its national rollout continues.
"These areas join places up and down the country with access to superfast speeds from Virgin Media that allow users to download even high quality movies in less than a couple of minutes," the firm said.
Virgin Media explained that its programme of work to enable superfast 100Mb broadband is now "ahead of schedule" and will be complete this spring.
Originally the project was due to run until mid-2012.
Jon James, Executive Director of Broadband at Virgin Media, said that soon half the country will be able to get superfast 100Mb broadband from the firm.
"Reaching today's milestone puts us ahead of schedule as we help propel the UK up the global broadband rankings," he claimed.
"Broadband is coming of age as more people give up on slow DSL in favour of superfast fibre optic speeds."
Mr James added that Virgin Media was again confirmed as the fastest broadband provider by media regulator Ofcom last week.
"This, along with our fantastic TiVo TV service, means we have an incredible combination that lets our customers enjoy the digitally connected world to the full," he said.
Last month, Virgin Media announced plans to double the speeds available to customers on its 10Mb, 20Mb and 30Mb broadband packages.
And higher-tier subscribers, those on a 50Mb or 100Mb broadband deal, are set to see download speeds increase to 120Mb.
This will increase the range of options for consumers looking to play games, download albums or stream high definition TV services over the internet.
