The latest certificate is from June 2016, so improvements made since then won't be reflected.

It hasn't traded since June 1999, a hold of 27 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 147 m² the property is well over the postcode median (85 m² across 20 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 85% of similar EPCs). Today's modelled estimate of £308,000 sits 262.4% above the 1999 sale of £85,000. On a £-per-square-foot basis, the last sale (£54/sq ft) was about 64.1% below the postcode norm.
