The latest certificate (March 2009) shows a D (score 61), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 71).

It hasn't traded since July 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 89 m² it sits well below the postcode median (137 m² across 12 EPCs), making it one of the more compact homes locally. Today's modelled estimate of £444,000 is 30.6% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£356/sq ft) was about 67.9% above the typical sold price in the postcode.
