Overview

About 12a

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

12a is an end-of-terrace house in St. Mellons, Cardiff, Cardiff (CF3 0SD). It has a recorded floor area of 63 m² (around 678 sq ft), construction records dating it to 1991-1995 and council tax band C. The latest certificate (August 2016) shows a C (score 69), just inside the C band. The recommended improvements would push it to B (score 84). The latest certificate is from August 2016, so improvements made since then won't be reflected.

Held since March 2001 — that's 25 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £210,000 sits 312.6% above the 2001 sale of £50,900. On a £-per-square-foot basis, the last sale (£75/sq ft) was about 55.5% below the postcode norm.

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 63 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF3 0SD. 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 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 August 2016 at band C and expired in August 2026, 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 0SD.
Council tax band
12a is in council tax band C. 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.
