The latest certificate is from August 2013, so improvements made since then won't be reflected.

It hasn't traded since October 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 36 m² it sits well below the postcode median (66 m² across 20 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 70% of similar EPCs). Today's modelled estimate of £110,000 is 29.4% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£219/sq ft) was about 28.6% above the typical sold price in the postcode.
