Overview

About 22 Allen Close

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

22 Allen Close is a detached house in Old St. Mellons, Cardiff, Cardiff (CF3 5DH). It has a recorded floor area of 72 m² (around 775 sq ft), construction records dating it to 1996-2002 and council tax band E. The latest certificate (October 2013) shows a D (score 67), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 86), a 2-band jump. The latest certificate is from October 2013, so improvements made since then won't be reflected.

Today's modelled estimate of £289,000 sits 240% above the 1999 sale of £85,000. On a £-per-square-foot basis, the last sale (£110/sq ft) was about 23.6% below the postcode norm. One planning record on file: tree works approved in 2018. Past consents include tree works, meaningful when judging how the property has evolved.

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 22 Allen Close is modelled from its 72 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in CF3 5DH. 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. 2 sales are recorded for 22 Allen 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 22 Allen Close was lodged in October 2013 at band D and expired in October 2023, 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 22 Allen 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 5DH.
Council tax band
22 Allen Close 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.
