Valuation method in detail
How the estimate is made
The estimate for 8 Clos Cilfwnwr is modelled from its 97 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in SA4 9BU. 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 8 Clos Cilfwnwr. 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 8 Clos Cilfwnwr was lodged in September 2024 at band A and is valid until September 2034. 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 8 Clos Cilfwnwr. 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 14 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from SA4 9BU.
Council tax band
