The recommended improvements would lift it to B (score 85), a 3-band jump. The latest certificate is from April 2016, so improvements made since then won't be reflected.

It hasn't traded since February 2006, a hold of 20 years that's notably long for the area. Today's modelled estimate of £521,000 sits 96.6% above the 2006 sale of £265,000.
