About 11a
11a is a two-bedroom end-of-terrace house in Harrow (HA2 0JD). It has a recorded floor area of 72 m² (around 775 sq ft), construction records dating it to before 1900 and council tax band E. At 72 m² this is the 7th smallest of 11 units on EPC record in the building, where floor areas span 44–145 m². The building's EPC ratings span E to C, with this unit at the top.

Between certificates, lighting went from Good to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good.
