Overview

About 1 Southminster Road

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

1 Southminster Road is a four-bedroom end-of-terrace house in Cardiff (CF23 5AT). It has a recorded floor area of 110 m² (around 1179 sq ft), construction records dating it to 1930-1949 and council tax band F. The latest certificate (January 2009) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 71), a 2-band jump. The latest certificate is from January 2009, so improvements made since then won't be reflected. Period features are noted in the property record. Our model identifies extension potential, subject to local planning policy.

Untraded for 17 years, with the last transfer in June 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £443,000 sits 101.4% above the 2009 sale of £220,000. At 110 m² it's 20.6% smaller than the typical home in the postcode (138 m² median across 23 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 87% of similar EPCs). One historical planning record sits against the property in 2013.

Method

How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
Valuation method in detail
How the estimate is made
The estimate for 1 Southminster Road is modelled from its 110 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF23 5AT. 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 1 Southminster 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 1 Southminster Road was lodged in January 2009 at band E and expired in January 2019, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
Planning records
Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 1 Southminster 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 CF23 5AT.
Council tax band
1 Southminster 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.
