Overview

About 12a

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

12a is a two-bedroom end-of-terrace house in St. Mellons, Cardiff, Cardiff (CF3 0BF). It has a recorded floor area of 65 m² (around 700 sq ft), construction records dating it to 2003-2006 and council tax band D. The latest certificate (June 2015) shows a C (score 71). The recommended improvements would push it to B (score 85). The latest certificate is from June 2015, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history.

Most recent transfer: September 2021 at £186,000. Across the public record there are 4 sales, relatively high churn for a single property. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. Across 2006–2021, sale prices on this property compounded at 1.6% per year. Today's modelled estimate of £241,000 is 29.6% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£266/sq ft) was about 31.2% 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 12a is modelled from its 65 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in CF3 0BF. 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. 4 sales are recorded for 12a. 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 12a was lodged in June 2015 at band C and expired in June 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 12a. 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 0BF.
Council tax band
12a 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.
