The locations for the series' filmed sequences were the universities of Keele and Birmingham. Most episodes of series 1 begin with sequences shot from the roof of the Arts Building tower at Birmingham, revealing the distinctive Ashley and Strathcona Buildings as the refuse truck drives along Ring Road North past the School of Education building and sometimes past residential block D at Keele. The scenes involving the lake were shot in the vicinity of the Vale halls of residence at Birmingham; the buildings that can be seen around the lake were demolished and replaced with modern student residences in 2006. Also used for exterior filming was the BT engineer training school at Yarnfield Park in Staffordshire. Most of the interiors were shot at BBC Pebble Mill (first series) and London (second), in the common combined film/video format.
