Virgin Media is rolling out ultrafast broadband to more homes and businesses in London.
Approximately 100,000 new premises have been connected to its fibre-rich network in the capital since 2014.
Furthermore, Virgin Media believes it is on course to deliver ultrafast broadband to an additional 100,000 London premises by early 2017.
The company then expects to cover the remaining 250,000 by the end of 2018, which takes the overall total up to 450,000.
Areas set to benefit include Westminster, Barnet, St John's Wood, Twickenham and Hammersmith & Fulham.
The work is being carried out as part of Virgin Media’s £3 billion Project Lightning investment plan, which has seen fibre broadband offering speeds of up to 300Mbps being rolled out across the UK.
Tom Mockridge, Chief Executive of Virgin Media, commented: "London is one of the greatest capital cities in the world, so it deserves connectivity that meets its standing on the global stage. "This expansion will give Londoners the broadband boost they deserve."
"Our £3 billion Project Lightning network expansion is gaining momentum and by 2019, 17 million homes and businesses in the UK will have access to our ultrafast network.”
Households will receive broadband speeds of up to 200Mbps, which Virgin Media says is more than two-and-a-half times faster than the maximum speeds offered by Sky, TalkTalk and BT.
This, it stated, means every member of the family will be able to stream music, watch movies and perform other tasks online all at the same time.
Businesses with ultrafast connections will benefit from speeds of up to 300Mbps. Virgin Media says this is nearly four times faster than the maximum speeds available from its competitors.
