The cable operator made the announcement while reporting record performance in the three months to June 30, including the addition of 9,100 net new customers.
Over the quarter, Virgin added 28,100 net new broadband customers and 22,300 net new digital TV subscribers, helping overall revenue grow 7.1% to £964m.
Moving forward, the company has confirmed plans to start offering a broadband package of 100 megabits per second in the fourth quarter of this year.
Customers taking the service will be able to download an hour-long standard definition TV show in 31 seconds or a full high definition movie in seven minutes 25 seconds.
Also in Q4, Virgin Media will launch its first set top boxes featuring a new television and broadband interactive User Interface (UI) created by American firm TiVo.
The new UI is designed to seamlessly blend linear TV and on-demand content, along with opening up a range of online functionality, such as recommendations engines and social media functions.
In a statement today, Virgin Media chief executive Neil Berkett said that the company's strong performance in Q2 was "driven by our ability to offer households and businesses an increasingly differentiated range of digital services".
He added: "Going forward, we'll continue to differentiate our propositions by proactively exploiting the advantages of our network and our mobile capability."
Virgin Media also recently revealed plans to offer 3D content to subscribers via its on-demand platform, with the firm's new V HD Box offering full support for 3D streams.
