2 Jillian Court is a semi-detached house in Surbiton (KT6 4SY). It has a recorded floor area of 59 m² (around 635 sq ft), construction records dating it to 1950-1966 and council tax band D. At 59 m² this is the smallest unit on EPC record across the building (59–63 m²). The building's EPC ratings span F to C across 9 units on file. The latest certificate (January 2014) shows an E (score 44), well below the UK norm with real room to improve. Earlier certificates rated it D (August 2012); the latest reading is one band lower. Between certificates, wall efficiency went from Poor to Good and lighting went from Very Poor to Average; while hot-water efficiency dropped from Good to Very Poor and main heating dropped from Good to Very Poor. The recommended improvements would lift it to C (score 77), a 2-band jump. Main heating runs on to be used only when there is no heating/hot. The latest certificate is from January 2014, so improvements made since then won't be reflected.
