About 115 Dinas Street
115 Dinas Street is a mid-terrace house in Plasmarl, Swansea, Swansea (SA6 8LL). It has a recorded floor area of 74 m² (around 797 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (December 2013) shows an E (score 49), well below the UK norm with real room to improve. The rating has held steady at E across 3 certificates since January 2012. Between certificates, roof efficiency went from Poor to Good, window efficiency went from Poor to Good and lighting went from Average to Good. The recommended improvements would lift it to B (score 87), a 3-band jump. The latest certificate is from December 2013, so improvements made since then won't be reflected.
