Overview

About 21 Ironbridge Road

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

21 Ironbridge Road is a three-bedroom mid-terrace house in Tongwynlais, Cardiff, Cardiff (CF15 7NJ). It has a recorded floor area of 77 m² (around 825 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (May 2009) shows an E (score 51), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 65). The latest certificate is from May 2009, so improvements made since then won't be reflected.

Held since May 2003 — that's 23 years off the open market, well above the local norm. Today's modelled estimate of £257,000 sits 144.8% above the 2003 sale of £105,000. On a £-per-square-foot basis, the last sale (£127/sq ft) was about 31.8% below the postcode norm. One planning record on file: tree works approved in 2023.

Valuation method in detail
How the estimate is made
The estimate for 21 Ironbridge Road is modelled from its 77 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF15 7NJ. 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 21 Ironbridge Road. 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 Ironbridge Road was lodged in May 2009 at band E and expired in May 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. 1 application is matched to 21 Ironbridge Road. 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 13 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF15 7NJ.
Council tax band
21 Ironbridge Road 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.
