Overview

About 21 Eider Close

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

21 Eider Close is a two-bedroom semi-detached house in St. Mellons, Cardiff, Cardiff (CF3 0DF). It has a recorded floor area of 46 m² (around 495 sq ft), construction records dating it to 1983-1990 and council tax band B. At 46 m² this is the 4th smallest of 14 units on EPC record in the building, where floor areas span 37–108 m². The building's EPC ratings span E to C, with this unit at the top.

Between certificates, wall efficiency went from Average to Good; while lighting dropped from Average to Poor. The latest certificate is from August 2016, so improvements made since then won't be reflected.

Valuation method in detail
How the estimate is made
The estimate for 21 Eider Close is modelled from its 46 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in CF3 0DF. 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 21 Eider 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 21 Eider Close was lodged in August 2016 at band C and expired in August 2026, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 21 Eider 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 0DF.
Council tax band
21 Eider Close is in council tax band B. 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.
