A TalkTalk spokesperson said: "While some of our prices are changing, millions of TalkTalk customers can reduce their monthly bill and pay less than they do today by switching to our Fixed Low Price Plans.
"They'll be guaranteed no broadband price hikes for 18 months - something which no other provider can guarantee. And if they see a better deal from TalkTalk, the can switch and save money."
