Openreach has pledged to make fibre-to-the-premises (FTTP) broadband available to three million premises by 2020.
FTTP offers speeds of up to 1Gbps, which is enough to stream 200 HD movies simultaneously, and significantly faster than the 24Mbps speeds delivered by superfast broadband.
The work will start in the next few months in Birmingham, Bristol, Cardiff, Edinburgh, Leeds, Liverpool, London and Manchester.
Openreach believes this will set it "on the right trajectory" to achieve its goal of building a ten million FTTP footprint by the mid-2020s.
Indeed, Chief Executive Clive Selley said the new "fibre first" programme "fires the starting pistol on a potentially huge upgrade of critical UK infrastructure".
"Fibre first is more than just a programme," he continued.
"It’s about how Openreach thinks, and is approaching the challenge of building a large-scale FTTP network for the UK. That means wherever we can in the future, we will build fibre first - including in rural areas."
Mr Selley stated that the UK is currently experiencing a technological revolution, with the internet's influence constantly growing and evolving.
Indeed, he noted that just three years ago, British households used less than half the data they do now on their home broadband, while average speeds were a third of what they are today.
Mr Selley therefore believes it is important to invest in the next generation of faster broadband technology "in order to stay afloat on this digital tidal wave".
"I believe Openreach can be at the heart of this digital revolution and has a critical role to play in ensuring the UK has a FTTP network, fit for the future," he commented.
"The prize for our wholesale customers, their customers and the UK as a whole is huge."
Mr Selley went on to hail the government's recent announcement its goal of extending superfast broadband to 95 per cent of the UK by the end of 2017 has been achieved.
He stated that passing more than 27 million homes and businesses with superfast broadband is a "momentous milestone". However, he said it is also a "stepping stone to something much bigger".
