About Flat
Flat is an end-of-terrace house in Sunderland (SR6 7DL). It has a recorded floor area of 66 m² (around 710 sq ft), construction records dating it to 1900-1929 and council tax band A. At 66 m² this is the smallest unit on EPC record across the building (66–117 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 (47 versus a best of 71). The latest certificate (January 2019) shows an E (score 47), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 70), a 2-band jump.
