Residents in 2.7 million apartments around the UK are now able to access super-fast broadband using BT's fibre network, it has been claimed.
According to Openreach - the firm which manages BT's network infrastructure - the flats have access to a mixture of fibre-to-the-cabinet (FTTC) and fibre-to-the-premises (FTTP) technology.
Some 608,000 apartments with FTTP or FTTC access are in Greater London, with the network expected to reach a further 550,000 in the capital over the coming years.
Openreach explained that more than 70 broadband providers offer services over BT's wholesale network, giving potential customers a range of subscription options.
"A fibre broadband connection offering download speeds of up to 80Mb in FTTC areas or up to 300Mb in FTTP areas means that residents of apartments can do so much more online," the firm stated.
"Download songs in two seconds, entire albums in 30 seconds, HD-TV programmes in five minutes and feature-length HD movies in less than ten minutes – all at the same time."
Openreach added that for people who want to work at home, fibre broadband enables them to be just as productive as if they were in the office.
Fibre broadband allows professional people to share files and videoconference with other sites, suppliers and clients, the firm noted.
