Get startedFlat 3 is a mid-terrace house in Kensington And Chelsea, London, London (SW3 1NG). It has a recorded floor area of 51 m² (around 549 sq ft) and construction records dating it to 1900-1929.

The latest certificate (November 2014) shows a C (score 71). The rating has held steady at C across 3 certificates since December 2008. Between certificates, wall efficiency went from Very Poor to Poor and window efficiency went from Average to Good; while hot-water efficiency dropped from Very Good to Average and main heating dropped from Very Good to Very Poor. The recommended improvements would push it to B (score 82). Main heating runs on electricity. The latest certificate is from November 2014, so improvements made since then won't be reflected.
