TalkTalk Pro, which costs £14.99 per month, offers broadband speeds of up to 24Mbps and unlimited download limits along with a free 'N' wireless router and free calls to UK landlines, as well as 0845 and 0870 numbers.
The deal is subject to an 18-month contract and users will also be required to pay a monthly line rental of £11.25.
The ISP says the deal is over £150 cheaper than similar offerings from Virgin and £300 less than Sky's Unlimited package.
TalkTalk's Tristia Clarke said: "Once again TalkTalk is challenging the market and providing unbeatable value by offering a premium broadband product at a much lower price than its competitors' packages."
TalkTalk says the package will appeal to 'Digital Extroverts' or early adopters of new technologies and services, who regularly upload content online and view the internet as essential to their daily lives.
