Overview

About 8 Clos Alyn

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

8 Clos Alyn is a three-bedroom semi-detached house in Pontprennau, Cardiff, Cardiff (CF23 8LB). It has a recorded floor area of 90 m² (around 969 sq ft), construction records dating it to 1976-1982 and council tax band E. The latest certificate (April 2015) shows a D (score 64), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since December 2011. Between certificates, hot-water efficiency went from Average to Good; while wall efficiency dropped from Good to Average and roof efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from April 2015, so improvements made since then won't be reflected.

Across 2002–2013, sale prices on this property compounded at 3.9% per year. Today's modelled estimate of £290,000 sits 67.6% above the 2013 sale of £173,000. One planning record on file: an extension approved in 2021. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved. Last sold in May 2013, so it's been off the market for around 13 years.

Valuation method in detail
How the estimate is made
The estimate for 8 Clos Alyn is modelled from its 90 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in CF23 8LB. 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. 3 sales are recorded for 8 Clos Alyn. 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 8 Clos Alyn was lodged in April 2015 at band D and expired in April 2025, 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 8 Clos Alyn. 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 8LB.
Council tax band
8 Clos Alyn is in council tax band E. 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.
