Overview

About 9 Cathcob Close

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

9 Cathcob Close is a three-bedroom mid-terrace house in St. Mellons, Cardiff, Cardiff (CF3 0AH). It has a recorded floor area of 92 m² (around 990 sq ft), construction records dating it to 1983-1990 and council tax band C. The latest certificate (June 2026) returns a high B (score 91), putting the home a stone's throw from an A rating. When first surveyed in March 2011 the rating was D, the property has climbed 2 bands since. Between certificates, wall efficiency went from Average to Good. This certificate was lodged in the last six months, so the rating reflects current condition. Other recorded features include a conservatory.

Most recent transfer: July 2021 at £160,000. Across the public record there are 4 sales, relatively high churn for a single property. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One planning record on file: an extension approved in 2013. Past consents include an extension and change of use to residential, meaningful when judging how the property has evolved. Its energy rating outperforms most of the postcode (better than 83% of similar EPCs). Across 2003–2021, sale prices on this property compounded at 4.7% per year. Today's modelled estimate of £229,000 is 43.1% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£162/sq ft) was about 58.2% above the typical sold price in the postcode.

Valuation method in detail
How the estimate is made
The estimate for 9 Cathcob Close is modelled from its 92 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in CF3 0AH. 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. 4 sales are recorded for 9 Cathcob Close. 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 9 Cathcob Close was lodged in June 2026 at band B and is valid until June 2036. 3 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 9 Cathcob Close. 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 0AH.
Council tax band
9 Cathcob Close is in council tax band C. 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.
