Sky has announced that it has connected the first customer to its fibre-to-the-home (FTTH) broadband network in York, making it the first city to be connected to ultrafast broadband.
The company's new service will enable broadband speeds of up to 940 Mbps, nearly 500 times faster than its existing service.
The increased download speeds of the service mean customers will be able to download a high-definition video in less than 30 seconds, while the pure fibre network will bring greater stability and reliability than standard fibre broadband.
It means that even when numerous people are using the same connection, it will never slow down.
Lyssa McGowan, Director of Sky Broadband, said: “Sky is the first broadband service provider in the UK to offer guaranteed broadband speeds.
"We are proud that these products will be available to our customers in York on our ultrafast and ultra-reliable gigabit network.
"As Ofcom continues its review of the broadband market, we believe that trials like this are a valuable demonstration of the alternative technologies now available.
"With the right conditions for investment and innovation, consumers and businesses could benefit from more ultrafast connections across the UK.”
Unlike the BT Openreach network, Sky's FTTH network is based entirely on the latest fibre technology, with no reliance on copper lines between the street cabinet and the home.
Sky claims it is building the network in partnership with TalkTalk and CityFibre, with a view to further testing the potential for the technology and gauging the response of customers.
