Overview

About 20 Marle Close

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

20 Marle Close is a semi-detached house in Pentwyn, Cardiff, Cardiff (CF23 7EP). It has a recorded floor area of 58 m² (around 624 sq ft), construction records dating it to 2003-2006 and council tax band D. At 58 m² this is the 2nd smallest of 41 units on EPC record in the building, where floor areas span 57–131 m². The building's EPC ratings span D to B, with this unit at the bottom. On EPC score it ranks last in the building (66 versus a best of 85). The latest certificate (February 2013) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 82), a 2-band jump. Main heating runs on electricity. The latest certificate is from February 2013, so improvements made since then won't be reflected.

It hasn't traded since February 2006, a hold of 20 years that's notably long for the area. At 58 m² it's 18.9% smaller than the typical home in the postcode (72 m² median across 40 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £151,000 is 11.9% above the 2006 sale price. On a £-per-square-foot basis, the last sale (£216/sq ft) was about 22% above the typical sold price in the postcode.

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 20 Marle Close is modelled from its 58 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF23 7EP. 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 20 Marle 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 20 Marle Close was lodged in February 2013 at band D and expired in February 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. None is matched to 20 Marle 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 CF23 7EP.
Council tax band
20 Marle Close is in council tax band D. 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.
