Between certificates, roof efficiency went from Average to Very Good and lighting went from Poor to Average; while wall efficiency dropped from Average to Poor.

Valuation method in detail
How the estimate is made
The estimate for 3 Brynmawr Close is modelled from its 89 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF3 0HJ. 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 3 Brynmawr Close. 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 3 Brynmawr Close was lodged in February 2014 at band D and expired in February 2024, 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 3 Brynmawr Close. 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 0HJ.
Council tax band
3 Brynmawr Close 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.
