How to read this page

Valuation method in detail

How the estimate is made: The estimate for 15 Biddestone Avenue is modelled from its 99 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SN3 6DE. 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 15 Biddestone 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 15 Biddestone Avenue was lodged in May 2026 at band C and is valid until May 2036. 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 15 Biddestone 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: Crime is police-recorded street-level data over the last 15 months, which places each incident at an approximate point. The 17 schools and 30 stops listed are measured in a straight line from SN3 6DE, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
