About 18 Rockleigh Avenue
18 Rockleigh Avenue is a three-bedroom mid-terrace house in Leigh On Sea (SS9 1LA). It has a recorded floor area of 77 m² (around 829 sq ft), construction records dating it to 1900-1929 and council tax band C. The latest certificate (April 2016) shows a D (score 67), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 89), a 2-band jump. The latest certificate is from April 2016, so improvements made since then won't be reflected. The home occupies a cul-de-sac position.
