Between certificates, wall efficiency dropped from Poor to Very Poor and window efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 84), a 3-band jump.

Held since January 2008 — that's 18 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. Across 2004–2008, sale prices on this property compounded at 16.4% per year. Today's modelled estimate of £103,000 sits 50.4% above the 2008 sale of £68,500. On a £-per-square-foot basis, the last sale (£85/sq ft) was about 80.6% above the typical sold price in the postcode. At 75 m² it's 15.7% smaller than the typical home in the postcode (89 m² median across 9 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs).
