About Flat 1
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
Flat 1 is a semi-detached house in London (SW17 9AL). It has a recorded floor area of 45 m² (around 484 sq ft), construction records dating it to before 1900 and council tax band C. At 45 m² this is the smallest unit on EPC record across the building (45–67 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 (44 versus a best of 72). The latest certificate (November 2015) shows an E (score 44), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 74), a 2-band jump. Main heating runs on electricity.
