Virgin Media is to embark on the largest single expansion of its UK network since the company launched in 2007.
Some 100,000 homes and businesses across east London are to gain access to the firm's 152Mb fibre-optic broadband for the first time.
Premises across Bethnal Green, Isle of Dogs, Newham and West Ham will be the first to benefit from the network rollout, with those in Stratford, Poplar, Stepney, Bow and East Ham to follow.
Households in the newly-connected areas will be able to take advantage of Virgin Media's connected TiVo service, as well as ultra-fast broadband.
Tom Mockridge, Virgin Media's Chief Executive Officer, said extending its network into east London means 100,000 more homes will benefit from the UK’s fastest broadband for the first time.
He commented that this is a "significant investment" for the broadband provider.
"We are very proud to be supercharging east London, helping thousands of people make the most of the UK’s exciting digital future," Mr Mockridge added.
Boris Johnson, the Mayor of London, claimed that London is earning a reputation for being "the Tech capital of Europe".
"That is why we need to ensure every Londoner is able to access superfast broadband services," he added.
Mr Johnson said super-fast services have become a utility that every Londoner expects, and the latest expansion is "a further welcome step towards making that aim a reality".
At present, Virgin Media's network covers over half of all London homes.
It also powers Wi-Fi services on the London Underground, ensuring one million commuters can access the web on the Tube every day.
In addition, Hackney residents benefit from free public Wi-Fi, provided by Virgin Media Business as part of a partnership with the local council.
