About 11 Westbury Street
11 Westbury Street is a five-bedroom mid-terrace house in Swansea (SA1 4JN). It has a recorded floor area of 150 m² (around 1615 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (March 2016) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 70), a 2-band jump. The latest certificate is from March 2016, so improvements made since then won't be reflected.
