Overview

About 12 Celyn Grove

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

12 Celyn Grove is a four-bedroom semi-detached house in Cardiff (CF23 6SH). It has a recorded floor area of 163 m² (around 1755 sq ft), construction records dating it to 1930-1949 and council tax band G. The latest certificate (May 2025) shows a C (score 73). When first surveyed in November 2010 the rating was F, the property has climbed 3 bands since. Between certificates, wall efficiency went from Poor to Average, roof efficiency went from Good to Very Good and window efficiency went from Very Poor to Good.

Today's modelled estimate of £682,000 sits 139.3% above the 2013 sale of £285,000. On a £-per-square-foot basis, the last sale (£162/sq ft) was about 33.6% below the postcode norm.

Valuation method in detail
How the estimate is made
The estimate for 12 Celyn Grove is modelled from its 163 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF23 6SH. 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 12 Celyn Grove. 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 12 Celyn Grove was lodged in May 2025 at band C and is valid until May 2035. 4 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 12 Celyn Grove. 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 6SH.
Council tax band
12 Celyn Grove is in council tax band G. 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.
