18 William Mews is a two-bedroom mid-terrace house in Westminster, London, London (SW1X 9HF). It has a recorded floor area of 127 m² (around 1369 sq ft), construction records dating it to 1991-1995 and council tax band G. The latest certificate (February 2009) shows a C (score 77), near the top of the C band. The latest certificate is from February 2009, so improvements made since then won't be reflected. Other recorded features include a balcony.
