St Cheldon's Comprehensive School

St Cheldon's Comprehensive School was a school in Upminster, London.

In the 2000s, Coldfire Construction built a technology block used as a transducer to absorb energy from the Sun and destroy the Earth so the Slitheen could sell it off. The capacitors left a strange lingering smell and food went off. Before he moved to Ealing, Alan Jackson worked in IT at this block, noticing the smell. Sarah Jane Smith investigated this school as the same was happening at Park Vale Comprehensive School. UNIT later cleaned up the transducer once the Slitheen left Earth. Wendy was the head teacher.
