It has a recorded floor area of 48 m² (around 517 sq ft), construction records dating it to 1976-1982 and council tax band A. At 48 m² this is the 2nd smallest of 27 units on EPC record in the building, where floor areas span 46–138 m². The building's EPC ratings span E to B, with this unit at the bottom.

Earlier certificates rated it D (July 2013); the latest reading is one band lower. Between certificates, hot-water efficiency dropped from Average to Very Poor and lighting dropped from Good to Very Poor. The recommended improvements would lift it to C (score 76), a 2-band jump. The latest certificate is from December 2013, so improvements made since then won't be reflected.
