Structure E7: The Electrical Sub Station is a rectangular brick-built structure of cavity wall construction with an inner wall of red brick laid to English bond and faced in Burwell whites laid to stretcher bond. The building has a flat concrete roof. It is entered from the east through a double entrance, formerly with wooden doors, with a 3 light metal-framed window above. This is flanked to the north and south by four light metal framed windows with sloping tile sills. At the rear of the main transformer bay is a pebble-filled subfloor channel. On the rear and front internal walls are four electrical heaters and in the southeast corner are three steel CO2 cylinders which were connected to a fire suppressant system of red painted pipes, which could be activated by an external emergency pull handle to the south of the main door. At the north end of the building is a small self-contained switch room entered through a single door and lit by a two light metal framed window in its north wall. Internally is the remains of a large switch cabinet over a sub-floor duct, a sign on the cabinet reads ‘From 300KVA transformer’.
