Overview

About 20 Mathias Close

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

20 Mathias Close is a two-bedroom mid-terrace house in Penylan, Cardiff, Cardiff (CF23 9BE). It has a recorded floor area of 56 m² (around 603 sq ft), construction records dating it to 1991-1995 and council tax band D. The latest certificate (August 2013) shows a D (score 61), on the cusp of jumping into the C band. The recommended improvements would lift it to A (score 94), a 3-band jump. The latest certificate is from August 2013, so improvements made since then won't be reflected.

Held since November 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. Across 1996–2007, sale prices on this property compounded at 10.6% per year. Today's modelled estimate of £249,000 sits 59.6% above the 2007 sale of £156,000. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs).

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 Mathias Close is modelled from its 56 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in CF23 9BE. 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 20 Mathias 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 Mathias Close was lodged in August 2013 at band D and expired in August 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 Mathias 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 9BE.
Council tax band
20 Mathias 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.
