At 59 m² this is the 7th smallest of 25 units on EPC record in the building, where floor areas span 56–95 m². The building's EPC ratings span E to B, with this unit at the bottom. On EPC score it ranks last in the building (47 versus a best of 86). The latest certificate (July 2014) shows an E (score 47), well below the UK norm with real room to improve. Earlier certificates rated it D (August 2009); the latest reading is one band lower. Between certificates, hot-water efficiency went from Very Poor to Poor, lighting went from Very Poor to Very Good and main heating went from Poor to Average; while wall efficiency dropped from Good to Poor. The recommended improvements would push it to D (score 65). Main heating runs on electricity. The latest certificate is from July 2014, so improvements made since then won't be reflected.

Held since October 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 £273,000 sits 279.2% above the 1998 sale of £72,000. On a £-per-square-foot basis, the last sale (£113/sq ft) was about 50% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 83% of similar EPCs).
