At 95 m² this is the 39th smallest of 45 units on EPC record in the building, where floor areas span 32–229 m². The building's EPC ratings span E to C, with this unit at the bottom.

Untraded for 19 years, with the last transfer in April 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 95 m² the property is well over the postcode median (55 m² across 44 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs). Today's modelled estimate of £188,000 is 25.3% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£147/sq ft) was about 18.6% below the postcode norm.
