About 21 Islwyn Road

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

21 Islwyn Road is an end-of-terrace house in Mayhill, Swansea, Swansea (SA1 6SS). It has a recorded floor area of 72 m² (around 775 sq ft), construction records dating it to 1930-1949 and council tax band B. The latest certificate (April 2013) shows an E (score 46), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since September 2010. Between certificates, window efficiency went from Average to Good and main heating went from Average to Good; while lighting dropped from Poor to Very Poor.
