About 12b
12b is a three-bedroom semi-detached house in Southsea (PO5 3DP). It has a recorded floor area of 106 m² (around 1141 sq ft), construction records dating it to 1967-1975 and council tax band D. The latest certificate (July 2012) shows a D (score 60), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from July 2012, so improvements made since then won't be reflected.
