About 1a
1a is a detached house in Barnet (EN5 4AH). It has a recorded floor area of 208 m² (around 2239 sq ft), construction records dating it to 1967-1975 and council tax band G. The latest certificate (January 2016) shows a D (score 62), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since August 2014. Between certificates, roof efficiency went from Very Poor to Good; while lighting dropped from Good to Poor. The recommended improvements would push it to C (score 78). The latest certificate is from January 2016, so improvements made since then won't be reflected.

Today's modelled estimate of £1,222,000 sits 361.1% above the 1996 sale of £265,000.
