About 25 Castle Street
25 Castle Street is a two-bedroom end-of-terrace house in Newport (NP20 2DF). It has a recorded floor area of 67 m² (around 721 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (November 2014) shows an E (score 49), well below the UK norm with real room to improve. When first surveyed in July 2013 the rating was G, the property has climbed 2 bands since. Between certificates, roof efficiency went from Average to Good, hot-water efficiency went from Very Poor to Good and lighting went from Good to Very Good. The recommended improvements would lift it to B (score 85), a 3-band jump. The latest certificate is from November 2014, so improvements made since then won't be reflected.
