Overview

About 15 Mathias Close

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

15 Mathias Close is a two-bedroom end-of-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 1983-1990 and council tax band D. The latest certificate (March 2015) shows a D (score 68), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from March 2015, so improvements made since then won't be reflected.

It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs). Across 2015–2021, sale prices on this property compounded at 6.1% per year. Today's modelled estimate of £267,000 is 18.3% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£375/sq ft) was about 62.4% above the typical sold price in the postcode. Last sale on file: £225,750 in October 2021. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.

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 15 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 15 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 15 Mathias Close was lodged in March 2015 at band D and expired in March 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. None is matched to 15 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
15 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.
