Overview

About 6 Alderwood Close

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

6 Alderwood Close is a semi-detached house in St. Mellons, Cardiff, Cardiff (CF3 0BW). It has a recorded floor area of 67 m² (around 718 sq ft), construction records dating it to 1967-1975 and council tax band D. The latest certificate (June 2009) shows an E (score 47), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 55). Main heating runs on electricity. The latest certificate is from June 2009, so improvements made since then won't be reflected.

It hasn't traded since November 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £256,000 sits 89.6% above the 2009 sale of £135,000.

Valuation method in detail
How the estimate is made
The estimate for 6 Alderwood Close is modelled from its 67 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF3 0BW. 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 6 Alderwood 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 6 Alderwood Close was lodged in June 2009 at band E and expired in June 2019, 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 6 Alderwood 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 0BW.
Council tax band
6 Alderwood 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.
