About 12 Middleton Street

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

12 Middleton Street is an end-of-terrace house in St. Thomas, Swansea, Swansea (SA1 8HH). It has a recorded floor area of 79 m² (around 850 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (January 2023) shows a D (score 62), on the cusp of jumping into the C band. When first surveyed in March 2009 the rating was G, the property has climbed 3 bands since. Between certificates, window efficiency went from Average to Good, hot-water efficiency went from Very Poor to Good and lighting went from Very Poor to Very Good. The recommended improvements would lift it to B (score 86), a 2-band jump.
