At 107 m² this is the 47th smallest of 51 units on EPC record in the building, where floor areas span 22–143 m². The building's EPC ratings span E to C, with this unit at the bottom. On EPC score it ranks last in the building (43 versus a best of 78). The latest certificate (November 2014) shows an E (score 43), well below the UK norm with real room to improve. Earlier certificates rated it D (June 2009); the latest reading is one band lower. Between certificates, window efficiency dropped from Poor to Very Poor and hot-water efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 81), a 3-band jump. The latest certificate is from November 2014, so improvements made since then won't be reflected.
