About 21 Brynbala Way

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

It has a recorded floor area of 122 m² (around 1313 sq ft), construction records dating it to 1967-1975 and council tax band C. The latest certificate (March 2015) shows a C (score 70). The rating has held steady at C across 2 certificates since August 2014. Between certificates, lighting went from Good to Very Good; while roof efficiency dropped from Good to Very Poor.

How to read this page

Valuation method in detail
How the estimate is made
The estimate for 21 Brynbala Way is modelled from its 122 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF3 1SX. 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 Brynbala Way. 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 Brynbala Way was lodged in March 2015 at band C and expired in March 2025, 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 Brynbala Way. 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 1SX.
Council tax band
21 Brynbala Way 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.
