At 28 m² this is the 3rd smallest of 21 units on EPC record in the building, where floor areas span 26–185 m². The building's EPC ratings span E to C, with this unit at the bottom. On EPC score it ranks last in the building (46 versus a best of 76). The latest certificate (October 2008) shows an E (score 46), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 84), a 3-band jump. Main heating runs on electricity. The latest certificate is from October 2008, so improvements made since then won't be reflected.

Held since May 2009 — that's 17 years off the open market, well above the local norm. Across the public record there are 5 sales, relatively high churn for a single property. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 28 m² it sits well below the postcode median (89 m² across 20 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Across 1999–2009, sale prices on this property compounded at 8.2% per year. Today's modelled estimate of £191,000 is 38.4% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£461/sq ft) was about 42.5% above the typical sold price in the postcode.
