Overview

About 9 St Mellons Road

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

9 St Mellons Road is a detached house in Marshfield, Cardiff, Cardiff (CF3 2TX). It has a recorded floor area of 102 m² (around 1098 sq ft), construction records dating it to 1930-1949 and council tax band F. The latest certificate (October 2013) shows a D (score 56), a step below the typical UK home. When first surveyed in August 2013 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Good, roof efficiency went from Average to Good and hot-water efficiency went from Poor to Average; while lighting dropped from Good to Very Poor. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from October 2013, so improvements made since then won't be reflected.
