Get started10 Astell Street is a five-bedroom mid-terrace house in Kensington And Chelsea, London, London (SW3 3RU). It has a recorded floor area of 448 m² (around 4818 sq ft), construction records dating it to before 1900 and council tax band H. The latest certificate (January 2011) shows an E (score 51), well below the UK norm with real room to improve. Earlier certificates rated it D (September 2009); the latest reading is one band lower. The latest certificate is from January 2011, so improvements made since then won't be reflected.
