The rating has held steady at C across 3 certificates since March 2014. Between certificates, wall efficiency dropped from Good to Poor. The recommended improvements would push it to B (score 82).

It hasn't traded since May 2007, a hold of 19 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 176 m² the property is well over the postcode median (122 m² across 23 EPCs), placing it in the larger end of the local stock. One planning record on file: an extension approved in 2016. Past consents include an extension and partial demolition, meaningful when judging how the property has evolved. Across 2000–2007, sale prices on this property compounded at 14.4% per year. Today's modelled estimate of £358,000 is 33.6% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£141/sq ft) was about 35.8% above the typical sold price in the postcode.
