Flat 2, 13 Calthorpe Road, Banbury, OX16 5HS

Flat 2 is a one-bedroom mid-terrace house in Banbury (OX16 5HS). It has a recorded floor area of 56 m² (around 603 sq ft), construction records dating it to before 1900 and council tax band A. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. At 56 m² this is the 3rd smallest of 4 units on EPC record in the building, where floor areas span 47–61 m². The building's EPC ratings span E to D, with this unit at the bottom. On EPC score it ranks last in the building (46 versus a best of 63). The latest certificate (May 2014) shows an E (score 46), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 82), a 3-band jump. Main heating runs on electricity. The latest certificate is from May 2014, so improvements made since then won't be reflected.
