About 1 Margaret Street
1 Margaret Street is a three-bedroom end-of-terrace house in St. Thomas, Swansea, Swansea (SA1 8HT). It has a recorded floor area of 103 m² (around 1114 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (November 2009) shows an E (score 44), well below the UK norm with real room to improve. When first surveyed in February 2009 the rating was G, the property has climbed 2 bands since. Between certificates, hot-water efficiency went from Very Poor to Good, lighting went from Average to Very Good and main heating went from Poor to Good. The latest certificate is from November 2009, so improvements made since then won't be reflected.
