The latest certificate (September 2021) shows a D (score 67), on the cusp of jumping into the C band. Earlier certificates rated it C (September 2011); the latest reading is one band lower.

Today's modelled estimate of £6,578,000 is 30.4% below the 2021 sale of £9,445,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£1,011/sq ft) was about 65.9% above the typical sold price in the postcode. At 868 m² it sits well below the postcode median (1488 m² across 5 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs). 7 planning records sit against the property, 6 approved, 1 refused. Past consents include tree works, an extension, a basement excavation and new windows, meaningful when judging how the property has evolved. Sold December 2021 for £9,445,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
