Unveiled in February, the 100Mbps service will be the fastest commercially available broadband speed in Britain. The connection will allow users to download an entire music album in around five seconds or a TV show in around 30 seconds. A full high definition movie will take just 7 minutes.
Virgin Media said that the speed will demonstrate its "clear network advantage over rival broadband providers". It further hopes that the superfast speed will help "propel the UK up the global broadband league table".
Welcoming the development, Prime Minister David Cameron said: "We want to see superfast broadband brought to people's homes and businesses right across the country and this exciting news takes us a step closer towards reaching that goal."
Neil Berkett, Virgin Media's chief executive, added: "The launch of our 100Mb service is a significant milestone in the UK's broadband evolution and a vivid illustration of the power of our next generation network.
"From establishing the UK's first ever broadband service in 2000 to the launch of 100Mbps in 2010, in the space of just ten years Virgin Media has led the greatest developments in digital Britain. The world of possibilities that broadband will enable is set to explode and we're excited about the innovations we can bring to consumers in the next decade."
The 100Mbps service will be rolled out across Virgin Media's entire cable network, which reaches nearly 13m households. The first areas to receive the service will include parts of London, the South East and Yorkshire. The rollout is expected to be complete by mid 2012.
As well providing 100Mbps download speeds, the service will also deliver 10Mbps upload speeds, enabling users to share content such as live high definition video.
The package comes with a custom built combined modem and wireless 'N' router, which has the potential to deliver speeds of up to 400Mbps as new services roll out in the future. Pre-registration for the 100Mbps service has started now on Virgin Media's website.
Berkett added: "We have already seen a massive uptake in the number of customers watching video-rich services and bandwidth-hungry high definition programmes and clips.
"We are now in a world where people want the best connectivity with whatever screen they are using and those service providers that aren't able to deliver this will simply be left behind."
In financial results for the three months to September 30, Virgin Media added 33,800 net new broadband customers, bringing its base to 4.24m. Around 700,000 of the company's broadband subscribers now take packages of 20Mbps or 50Mbps, up 41% year-on-year.
