In this year's series of The Great British Bake Off twelve amateur bakers started the competition and they were gradually eliminated during each round of the contest. Unlike series 1, this year the competition was held in a single location - in the ground of Valentines Mansion, a 17th-century mansion house in Redbridge. In addition to their on-screen presenting roles, Mel Giedroyc and Sue Perkins also took over the narration of the show, which in series 1 had been done by Stephen Noonan. Series 2 also introduced the "star baker" award for the most impressive performer each week. Three and a half thousand people applied for the competition, and 12 were selected. Each episode was filmed over two 14-hour days.
