Valuation method in detail
How the estimate is made
The estimate for 21 Windway Avenue is modelled from its 87 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in CF5 1AP. 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. 3 sales are recorded for 21 Windway Avenue. 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 Windway Avenue was lodged in February 2018 at band D and is valid until February 2028. 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 21 Windway Avenue. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures
