Between certificates, window efficiency went from Very Poor to Poor and lighting went from Very Poor to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The recommended improvements would push it to B (score 84). The latest certificate is from May 2012, so improvements made since then won't be reflected.

On a £-per-square-foot basis, the last sale (£1,168/sq ft) was about 181.9% above the typical sold price in the postcode. Last sold in August 2012, so it's been off the market for around 14 years.
