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.

Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 1 sale is recorded for 9 St Mellons Road. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
