Overview

About 20 Penmaes

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

20 Penmaes is a four-bedroom detached house in Pentyrch, Cardiff, Cardiff (CF15 9QS). It has a recorded floor area of 146 m² (around 1572 sq ft), construction records dating it to 1976-1982 and council tax band F. The latest certificate (December 2015) returns a high B (score 87), putting the home a stone's throw from an A rating. The latest certificate is from December 2015, so improvements made since then won't be reflected. The home occupies a cul-de-sac position.

Held since July 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 146 m² it's 15.9% larger than the typical home in the postcode (126 m² median across 12 EPCs). On energy efficiency it sits in the top 10% of properties in this postcode. Across 1997–2007, sale prices on this property compounded at 9.5% per year. Today's modelled estimate of £477,000 sits 76.7% above the 2007 sale of £270,000. On a £-per-square-foot basis, the last sale (£172/sq ft) was about 24.7% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, 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 20 Penmaes is modelled from its 146 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in CF15 9QS. 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 20 Penmaes. 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 Penmaes was lodged in December 2015 at band B and expired in December 2025, 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. 2 applications are matched to 20 Penmaes. 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 13 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF15 9QS.
Council tax band
20 Penmaes is in council tax band F. 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.
