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 18 Bay Tree Close is modelled from its 77 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP11 1JN. 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 18 Bay Tree 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 18 Bay Tree Close was lodged in April 2025 at band D and is valid until April 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. None is matched to 18 Bay Tree 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 15 months, which places each incident at an approximate point. The 12 schools and 30 stops listed are measured in a straight line from HP11 1JN, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band: 18 Bay Tree 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.
