The recommended improvements would lift it to B (score 90), a 2-band jump.

It hasn't traded since August 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 36 m² it sits well below the postcode median (81 m² across 7 EPCs), making it one of the more compact homes locally. 2 planning records sit against the property, 2 approved, 0 refused. Today's modelled estimate of £228,000 is 13.3% above the 2009 sale price.
