At 37 m² this is the smallest unit on EPC record across the building (37–103 m²). The building's EPC ratings span F to C, with this unit at the bottom. On EPC score it ranks last in the building (31 versus a best of 74). The latest certificate (December 2015) shows an F (score 31), near the bottom of the EPC scale. When first surveyed in December 2015 the rating was G, the property has climbed 1 band since. Between certificates, lighting dropped from Good to Very Poor. The recommended improvements would lift it to C (score 78), a 3-band jump. Main heating runs on to be used only when there is no heating/hot. The latest certificate is from December 2015, so improvements made since then won't be reflected.

Held since October 2006 — that's 20 years off the open market, well above the local norm.
