Between certificates, lighting went from Average to Very Good; while roof efficiency dropped from Good to Average. The recommended improvements would push it to C (score 77).

Untraded for 19 years, with the last transfer in June 2007. 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 (69 m² across 5 EPCs), making it one of the more compact homes locally. Today's modelled estimate of £308,000 is 36.3% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£583/sq ft) was about 113.4% above the typical sold price in the postcode. One planning record on file: an extension refused in 2012.
