Overview

About 1 Barmouth Road

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

1 Barmouth Road is a four-bedroom semi-detached house in Rumney, Cardiff, Cardiff (CF3 3JZ). It has a recorded floor area of 122 m² (around 1313 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (March 2016) shows an E (score 48), well below the UK norm with real room to improve. Earlier certificates rated it D (October 2013); the latest reading is one band lower. Between certificates, wall efficiency went from Poor to Good; while roof efficiency dropped from Average to Very Poor and lighting dropped from Good to Poor. The recommended improvements would lift it to C (score 80), a 2-band jump. The latest certificate is from March 2016, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history.

At 122 m² the property is well over the postcode median (89 m² across 15 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs). Across 2015–2023, sale prices on this property compounded at 6.9% per year. On a £-per-square-foot basis, the last sale (£217/sq ft) was about 70.1% above the typical sold price in the postcode. Last sale on file: £285,000 in July 2023.

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 Barmouth Road is modelled from its 122 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in CF3 3JZ. 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. 2 sales are recorded for 1 Barmouth 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 1 Barmouth Road was lodged in March 2016 at band E and expired in March 2026, so a new one is needed to sell or let. 3 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 1 Barmouth 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 18 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF3 3JZ.
Council tax band
1 Barmouth Road is in council tax band C. 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.
