Customers who sign up to the 24-month deal will get internet access at up to 8Mbps, along with a free wireless router and unlimited evening and weekend calls to UK landlines.
Users will be required to fork out for TalkTalk's £11.49 line rental each month and a one-off £29.99 connection fee. Once the year is up, the internet access will then be charged at £6.99 per month.
To sign up to the offer, which is available until February 1, web users can either visit a carphone warehouse store, or visit the dedicated web page.
"Our 12-months free offer is unbeatable value and provides a great way for people to get online in 2010," said a TalkTalk spokesperson.
