The second series of The Great British Bake Off started 14 August 2011 with twelve amateur bakers. Unlike series one, the competition was held in a single location – the grounds of Valentines Mansion, a 17th-century mansion house in Redbridge. In addition to their on-screen presenting, Mel Giedroyc and Sue Perkins also took over the narration, which had been done by Stephen Noonan for the previous series. Series two also introduced the "star baker" award for the most impressive performer each week.
