Get started29 Cowper Gardens is a mid-terrace house in Wallington (SM6 9RN). It has a recorded floor area of 105 m² (around 1127 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (June 2009) shows an E (score 51), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 57).
