Between certificates, window efficiency dropped from Good to Average and hot-water efficiency dropped from Very Good to Good.

Held since September 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 54 m² it sits well below the postcode median (87 m² across 20 EPCs), making it one of the more compact homes locally. Across 2005–2007, sale prices on this property compounded at 11.1% per year. Today's modelled estimate of £201,000 is 18.9% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£291/sq ft) was about 27.1% above the typical sold price in the postcode.
