The recommended improvements would lift it to B (score 81), a 2-band jump. The latest certificate is from December 2010, so improvements made since then won't be reflected.

Held since July 1998 — that's 28 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £354,000 sits 280.6% above the 1998 sale of £93,000. On a £-per-square-foot basis, the last sale (£216/sq ft) was about 35% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs).
