Valuation method in detail
How the estimate is made
The estimate for 1 Harrison House is modelled from its 45 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP3 9DH. 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 1 Harrison House. 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 Harrison House was lodged in January 2026 at band C and is valid until January 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 1 Harrison 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 13 months, which places each incident at an approximate point. The 18 schools and 30 stops listed are measured in a straight line from HP3 9DH, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
