503a is a detached house in Thornton Heath (CR7 6AR). It has a recorded floor area of 67 m² (around 721 sq ft), construction records dating it to 1900-1929 and council tax band C. At 67 m² this is the 9th smallest of 12 units on EPC record in the building, where floor areas span 20–219 m². The building's EPC ratings span E to C across 12 units on file. The latest certificate (February 2016) shows a D (score 59), a step below the typical UK home. The recommended improvements would push it to C (score 77).
