Overview

About 12 Aster Close

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

12 Aster Close is a three-bedroom semi-detached house in St. Mellons, Cardiff, Cardiff (CF3 0JB). It has a recorded floor area of 74 m² (around 797 sq ft), construction records dating it to 1983-1990 and council tax band D. The latest certificate (April 2012) shows a C (score 69), just inside the C band. The recommended improvements would push it to B (score 83). The latest certificate is from April 2012, so improvements made since then won't be reflected. Other recorded features include attached land beyond the plot. The home occupies a cul-de-sac position.

At 74 m² it's 28.7% larger than the typical home in the postcode (58 m² median across 8 EPCs). Across 2001–2021, sale prices on this property compounded at 5.5% per year. Today's modelled estimate of £262,000 is 32.7% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£248/sq ft) was about 54.9% above the typical sold price in the postcode. Sold May 2021 for £197,500. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.

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 12 Aster Close is modelled from its 74 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in CF3 0JB. 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 12 Aster 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 12 Aster Close was lodged in April 2012 at band C and expired in April 2022, 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 12 Aster 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 CF3 0JB.
Council tax band
12 Aster 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.
