Overview

About 138 Rhiw R Ddar

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

138 Rhiw R Ddar is a three-bedroom semi-detached house in Taffs Well, Cardiff, Cardiff (CF15 7ND). It has a recorded floor area of 83 m² (around 896 sq ft), construction records dating it to 1967-1975 and council tax band D. The latest certificate (January 2009) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 71), a 2-band jump. The latest certificate is from January 2009, so improvements made since then won't be reflected. Other recorded features include notable views. Records show the property has been extended at some point in its history.

Held since December 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 83 m² it's 25.3% larger than the typical home in the postcode (66 m² median across 12 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £267,000 sits 74.5% above the 2009 sale of £153,000.

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 138 Rhiw R Ddar is modelled from its 83 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF15 7ND. 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 138 Rhiw R Ddar. 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 138 Rhiw R Ddar was lodged in January 2009 at band E and expired in January 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 138 Rhiw R Ddar. 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 7ND.
Council tax band
138 Rhiw R Ddar 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.
