Between certificates, wall efficiency dropped from Good to Poor and hot-water efficiency dropped from Good to Average. The recommended improvements would lift it to A (score 94), a 3-band jump.

Held since July 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. Across 2000–2007, sale prices on this property compounded at 8.2% per year. Today's modelled estimate of £690,000 sits 64.3% above the 2007 sale of £420,000. On a £-per-square-foot basis, the last sale (£187/sq ft) was about 33.4% above the typical sold price in the postcode. At 209 m² it's 20.1% larger than the typical home in the postcode (174 m² median across 5 EPCs).
