The latest certificate (February 2016) shows a C (score 79), near the top of the C band. Main heating runs on electricity: electricity, unspecified tariff.

Today's modelled estimate of £463,000 is 14.3% below the 2022 sale of £540,000, a rare downward gap that often correlates with deferred maintenance or unfinished works.

At 50 m² it sits well below the postcode median (89 m² across 33 EPCs), making it one of the more compact homes locally. Sold November 2022 for £540,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One historical planning record sits against the property in 2005.
