At 94 m² this is the 9th smallest of 12 units on EPC record in the building, where floor areas span 45–106 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 (53 versus a best of 78). The latest certificate (May 2012) shows an E (score 53), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 76), a 2-band jump. The latest certificate is from May 2012, so improvements made since then won't be reflected.
