Homes and businesses in Liverpool can now take advantage of Hyperoptic's 1Gb Fibre-to-the-Building (FTTB) broadband services.
Connections have gone live across five developments in the city, including Hamilton House, Waterloo Warehouse, The Reach and X Building, and fibre will soon be launching in Wapping Quay, Kings Dock Mill, Princes Dock and City Quay.
There are also a further 16 developments undergoing installation, meaning more people will be able to capitalise on ultra-fast connectivity before the end of 2015.
Hyperoptic's FTTB network will be able to deliver broadband speeds 50 times faster than the average connection in Liverpool, which according to Ofcom, offers 19.3Mb downloads.
This is because it uses fibre-optic connections all the way from the telephone exchange to each customer's landline, with no need for a copper link.
Tim Huxtable, National Team Manager at the service provider, claimed Hyperoptic is "revolutionising" broadband services in Liverpool.
"We are investing millions in telecoms infrastructure to extend our footprint," he stated.
"The reception to our services has been phenomenal - the difference in experience is like chalk and cheese - with 19.3Mbps, a 50GB game would take over seven hours to download, but less than seven minutes with our gigabit connection."
Joe Anderson, the Mayor of Liverpool, welcomed Hyperoptic to Merseyside, describing the network launch as being "tremendous news".
He said Hyperoptic’s offer helps transform Liverpool into a truly ‘Gigabit City’ and gives it a massive competitive edge.
Councillor Anderson said the local authority is aiming to grow the scale and breadth of businesses in the digital sector and improving broadband speeds is "essential in allowing that to happen".
"When we think of key utilities like water, gas and electricity we should also now think of super-fast broadband," he added.
"It’s an essential building-block in growing businesses and attracting new investment into the city as well as improving and future proofing the online lives of all."
