The latest certificate (November 2015) shows an E (score 53), well below the UK norm with real room to improve. Earlier certificates rated it D (June 2015); the latest reading is one band lower. Between certificates, wall efficiency went from Poor to Average; while roof efficiency dropped from Average to Poor and lighting dropped from Very Good to Very Poor. The recommended improvements would lift it to B (score 84), a 3-band jump. The latest certificate is from November 2015, so improvements made since then won't be reflected.

Held since January 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 65 m² it's 15.6% smaller than the typical home in the postcode (77 m² median across 29 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £115,000 sits 125.5% above the 2007 sale of £51,000.
