Overview

About 1 Crystal Avenue

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

1 Crystal Avenue is a four-bedroom detached house in Cardiff (CF23 5QJ). It has a recorded floor area of 176 m² (around 1894 sq ft), construction records dating it to 1950-1966 and council tax band G. The latest certificate (February 2014) shows an E (score 49), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 68). The latest certificate is from February 2014, so improvements made since then won't be reflected.

Held since October 1998 — that's 28 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. At 176 m² the property is well over the postcode median (90 m² across 11 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 82% of similar EPCs). Today's modelled estimate of £550,000 sits 570.7% above the 1998 sale of £82,000. On a £-per-square-foot basis, the last sale (£43/sq ft) was about 82.5% 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 1 Crystal Avenue is modelled from its 176 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF23 5QJ. 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 1 Crystal Avenue. 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 1 Crystal Avenue was lodged in February 2014 at band E and expired in February 2024, 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 1 Crystal Avenue. 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 CF23 5QJ.
Council tax band
1 Crystal Avenue is in council tax band G. 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.
