About 35a
35a is a semi-detached house in Isleworth (TW7 4AJ). It has a recorded floor area of 51 m² (around 549 sq ft), construction records dating it to 1900-1929 and council tax band D. At 51 m² this is the smallest unit on EPC record across the building (51–214 m²). The building's EPC ratings span D to C, with this unit at the bottom. The latest certificate (December 2015) shows a D (score 60), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 76).
