The latest certificate (June 2013) shows an E (score 44), well below the UK norm with real room to improve. Earlier certificates rated it D (February 2012); the latest reading is one band lower. Between certificates, hot-water efficiency dropped from Poor to Very Poor and main heating dropped from Average to Very Poor. The recommended improvements would lift it to C (score 79), a 2-band jump. Main heating runs on electricity. The latest certificate is from June 2013, so improvements made since then won't be reflected. At 72 m² this is the 8th smallest of 9 units on EPC record in the building, where floor areas span 24–72 m². The building's EPC ratings span G to C across 9 units on file.

It hasn't traded since September 1998, a hold of 28 years that's notably long for the area. 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 £149,000 sits 609.5% above the 1998 sale of £21,000. On a £-per-square-foot basis, the last sale (£27/sq ft) was about 83.8% below the postcode norm. At 72 m² it's 21% larger than the typical home in the postcode (60 m² median across 66 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 74% of similar EPCs).
