Sky has launched a new broadband service that will be offered free of charge to all of its 8 million customers.

All of Sky’s customers living in unbundled areas will be able to take Sky up on this offer, and Sky expects 30% of its eight million clients to sign up.

Price comparison website uSwitch.com believes this move will “revolutionise the telecommunications market”.

Tim Wolfenden, senior product manager at uSwitch.com said: “This is extremely exciting news for consumers as it heralds the arrival of genuinely free broadband. First of all we witnessed TalkTalk linking their proposition to the sale of their Home Telephony package, and then Orange doing the same thing with mobiles.

Yet he adds: “The Sky offer could shake the broadband market up dramatically, because they have four million customers who are currently with another provider, and who very soon are going to be able to turn around to that provider and say ‘Why should I carry on paying for my internet connection?’.”
