The latest certificate (April 2026) shows a D (score 61), on the cusp of jumping into the C band. When first surveyed in April 2016 the rating was E, the property has climbed 1 band since. The recommended improvements would push it to C (score 72). This certificate was lodged in the last six months, so the rating reflects current condition. At 48 m² this is the 3rd smallest of 4 units on EPC record in Alton Court, where floor areas span 44–50 m². The building's EPC ratings span D to C, with this unit at the bottom. On EPC score it ranks last in the building (61 versus a best of 70).
Untraded for 28 years, with the last transfer in March 1998. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time.
