Get started283 Headstone Lane is a two-bedroom mid-terrace house in Harrow (HA3 6PG). It has a recorded floor area of 82 m² (around 883 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (March 2016) shows a D (score 64), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since October 2014. Between certificates, roof efficiency went from Average to Good. The recommended improvements would lift it to B (score 81), a 2-band jump. The latest certificate is from March 2016, so improvements made since then won't be reflected.
