Valuation method in detail
How the estimate is made
The estimate for 9 Darleys Close is modelled from its 141 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP18 0SE. 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 9 Darleys Close. 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 9 Darleys Close was lodged in July 2025 at band E and is valid until July 2035. Floor area, heating and insulation details on this page come from it.
Planning records
Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 9 Darleys Close. 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. The 1 school and 14 stops listed are measured in a straight line from HP18 0SE, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
9 Darleys Close 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.
