21 Dulwich Wood Avenue is a semi-detached house in Southwark, London, London (SE19 1HB). It has a recorded floor area of 143 m² (around 1540 sq ft), construction records dating it to 1950-1966 and council tax band E. The latest certificate (July 2010) shows an E (score 51), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 65). The latest certificate is from July 2010, so improvements made since then won't be reflected.
