About 6 Islwyn Road
6 Islwyn Road is a two-bedroom mid-terrace house in Mayhill, Swansea, Swansea (SA1 6SS). It has a recorded floor area of 60 m² (around 646 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (June 2016) shows an E (score 49), well below the UK norm with real room to improve. Earlier certificates rated it D (January 2009); the latest reading is one band lower. Between certificates, lighting went from Poor to Average and main heating went from Average to Good; while wall efficiency dropped from Poor to Very Poor. The recommended improvements would lift it to B (score 87), a 3-band jump. The latest certificate is from June 2016, so improvements made since then won't be reflected.
