About 7 Ash Grove
7 Ash Grove is a two-bedroom semi-detached house in Staines Upon Thames (TW18 1JE). It has a recorded floor area of 83 m² (around 893 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (June 2015) shows a D (score 64), on the cusp of jumping into the C band. When first surveyed in May 2012 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Good and lighting went from Poor to Very Good. The recommended improvements would push it to C (score 79). The latest certificate is from June 2015, so improvements made since then won't be reflected.

At 83 m² it's 16.1% larger than the typical home in the postcode (72 m² median across 10 EPCs). Last sold in January 2016, so it's been off the market for around 10 years.
