Method

How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
Valuation method in detail
How the estimate is made
The estimate for 20 The Green is modelled from its 186 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP18 9RU. 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 20 The 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 20 The Green was lodged in July 2022 at band F and is valid until July 2032. 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 20 The 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. The 2 schools and 9 stops listed are measured in a straight line from HP18 9RU, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
20 The Green is in council tax band F. 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.
