The stands, which feature multimedia plasma screens and live digital satellite feeds, offer consumers direct access to Sky products and enable customers to subscribe to any service or to manage their accounts in person.
William Mellis, director of customer acquisition at BskyB, said: "Retail stores are an increasingly important part of our marketing capability, delivering an engaging experience for consumers who value face-to-face contact.
"Their success is demonstrated not only by the number but by the quality of customers joining Sky in this way."
Sky began its stand network with the acquisition of 59 stands owned by independent retailer You Me TV in July 2006.
Land Securities, which owns retail centres including Cardiff St. Davids, Leeds White Rose and Liverpool St. John, is just one of a number of shopping centre-owners that Sky has exclusive agreements with. These include Westfield, Capital Shopping Centres, Mall Corp, Prudential and Lend Lease.
