Overview

About 7 St Mellons Road

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

7 St Mellons Road is a detached house in Marshfield, Cardiff, Cardiff (CF3 2TX). It has a recorded floor area of 303 m² (around 3261 sq ft), construction records dating it to 2007 onwards and council tax band F. The latest certificate (July 2014) shows a C (score 76), near the top of the C band. When first surveyed in June 2009 the rating was E, the property has climbed 2 bands since. Between certificates, wall efficiency went from Good to Very Good, roof efficiency went from Average to Good and window efficiency went from Average to Good. The latest certificate is from July 2014, so improvements made since then won't be reflected.

Untraded for 17 years, with the last transfer in August 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 303 m² the property is well over the postcode median (114 m² across 23 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £632,000 sits 174.8% above the 2009 sale of £230,000. On a £-per-square-foot basis, the last sale (£71/sq ft) was about 72% below the postcode norm. One planning record on file: an extension approved in 2009. Past consents include an extension, meaningful when judging how the property has evolved.

Valuation method in detail
How the estimate is made
The estimate for 7 St Mellons Road is modelled from its 303 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF3 2TX. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
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 7 St Mellons Road. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC
Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 7 St Mellons Road was lodged in July 2014 at band C and expired in July 2024, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 7 St Mellons Road. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures
Crime is police-recorded street-level data over the last 18 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF3 2TX.
Council tax band
7 St Mellons Road is in council tax band F. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
