Between certificates, roof efficiency went from Very Poor to Good and hot-water efficiency went from Average to Good.

It hasn't traded since January 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 49 m² it sits well below the postcode median (98 m² across 21 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 71% of similar EPCs). On a £-per-square-foot basis, the last sale (£559/sq ft) was about 251.4% above the typical sold price in the postcode.
