TalkTalk is offering subscribers the chance to save £60 by waiving set-up fees on all its fibre products.
Among the deals where the saving is available is the TalkTalk Fast Broadband package.
This 12-month contract offers broadband speeds of up to 17Mbps and unlimited downloads, for a cost of £20 a month.
Another option for subscribers is the TalkTalk TV Plus, Faster Fibre & Phone deal, which also offers unlimited downloads and gives customers access to speeds of up to 38Mbps.
This 18-month contract costs £40 a month, plus £25 for a TV Plus box, which is 50 per cent cheaper than the regular price.
The device allows viewers to pause, rewind and record up to 180 hours of TV, as well as add and remove channels including Sky Sports and Sky Cinema on a flexible one-month contract.
This is the latest move by TalkTalk to bolster its proposition to customers, following its recent introduction of Fixed Low Price Plans.
In October, TalkTalk said it would seek to prevent customers experiencing "bill shock" by offering the new plans, which mean broadband prices would be fixed for 18 months.
The provider then announced in January it is extending this proposition further, ensuring people with 12 or 24-month contracts will not see prices go up during this period.
This week, TalkTalk said the response to this move has been "unprecedented", with more than 500,000 customers having switched to the plans by December 31st 2016.
Following the introduction of 12 and 24-month plans in January, an additional 80,000 customers re-contracted and three-quarters of new customers have since chosen to fix their price for 24 months.
