How to read this page

Valuation method in detail
How the estimate is made
The estimate for 1 Castle Green is modelled from its 147 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in PE32 2RL. 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 1 Castle Green. 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 1 Castle Green was lodged in June 2026 at band C and is valid until June 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. 1 application is matched to 1 Castle Green. 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 12 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from PE32 2RL. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
1 Castle Green is in council tax band E. 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.
