How the estimate is made
The estimate for Idsworth House is modelled from its 66 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in PO1 1HR. 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.

Start your researchHow to read this page
Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for Idsworth House is modelled from its 66 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in PO1 1HR. 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. No sale is recorded for Idsworth House, which usually means it hasn't changed hands since 1995 or the sale was not for value. 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 Idsworth House was lodged in December 2025 at band C and is valid until December 2035. 3 certificates are on record, which shows how the home has changed.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 2 applications are matched to Idsworth House. 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. The 40 schools and 30 stops listed are measured in a straight line from PO1 1HR, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- Idsworth House is in council tax band A. 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.
