Sky has sweetened its TV and broadband deals ahead of Christmas with the offer of a free Marks & Spencer voucher worth £50.

Under the terms of the limited-period promotion, all new customers who sign up online for any Sky package that combines a broadband connection with the company’s pay TV channels get the token free of charge. Sky’s previous incentive provided a Marks & Spencer voucher for £25.

Among the packages included in the promotion is the entry level Sky+ Starter. Priced £18 per month, this entitles customers to a broadband connection of up 2Mb and a free wireless router and anytime calls. They can also pick two Sky TV entertainment packs.

Those seeking a richer entertainment experience can opt for the Sky World and Sky+ HD bundle. This also includes a free wireless router, a 2Mb broadband connection and anytime calls. However, subscribers will additionally benefit from the full range of Sky entertainment packs, as well as the broadcaster’s sports and movie channels.

Premium programming on offer with Sky includes live action from the Premier League, the documentary-focussed National Geographic channel, movie premieres on Sky Movies and coverage of cultural events from Sky Arts.

Jessica McArdle, Marketing Manager at Top 10 Broadband, said: “This is not just a broadband promotion this is an M&S and Sky broadband promotion - the team at Top10 are pretty sure that you'll be able to taste the difference.”

Take up of Sky’s services is usually especially strong in the months before Christmas as Britons look to tailor their viewing over the festive period. This year’s flagship Christmas Day movie is Madagascar: Escape 2 Africa which will be making its UK TV debut on the network.

Sky’s £50 voucher promotion is one of an array of incentives currently being operated by broadband suppliers. 3 is offering all new customers who sign up online for its 24-month dongle deal at £15 per month a free voucher worth £20 to spend on accessories. Alternatively, new Be customers can bag themselves a £25 Amazon voucher as well as three months free broadband when they subscribe to any of its three broadband products.
