TalkTalk is offering new customers 12 months free ADSL broadband when they sign up to an 18 month contract.
The offer is available from today and runs until 19 February.
A £16.70 per month line rental applies and the broadband will cost an additional £3.50 a month after the initial 12 month free offer.
For the money, customers will enjoy speeds of up to 17mb, with no usage or download caps.
TalkTalk ISP claims the deal represents a saving of £250 compared to the equivalent BT package.
Customers will also get access to the new Talk2Go app which lets them pick up landline calls anywhere and make calls at landline rates via a mobile app.
