Plusnet is now offering 12-months' free internet services along with £50 cashback for new customers taking out its Unlimited Broadband and Calls package
The broadband deal ordinarily costs £9.99 per month plus line rental, but online subscribers can browse the web for free for the first year of their 18-month contract.
All they are required to pay for during this introductory offer period is line rental, which is priced at £15.95 per month, or the equivalent of £12.99 per month if paid a year in advance.
With £50 cashback thrown into the mix, customers can almost £170 on their broadband bills when they sign up with Plusnet.
The firm's Unlimited Broadband and Calls package offers download speeds of up to 17Mb with no restrictions on usage, meaning consumers can use as much data as they like.
Weekend calls to UK landlines are included as part of the deal, as is a free wireless router - which offers connectivity for a variety of web-enabled devices - and a free connection worth £25.
Plusnet is running the broadband deal until April 21st 2015, meaning UK consumers have over a week to take advantage of the offer.
The service provider is also offering £50 cashback with its Unlimited Broadband and Talk Anytime package, which allows subscribers to use their home phone 24/7.
In terms of deal features, this is essentially the same offer as Unlimited Broadband and Calls. However an upgrade to Talk Anytime - priced at £5 per month - is bolted on.
So for the first 12 months of an 18-month contract, new Plusnet Unlimited Broadband and Talk Anytime subscribers pay £5 per month plus line rental, rising to £14.99 per month thereafter.
They too can qualify for a discount on line rental by paying for a full year in a single instalment.
