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 11 The Square is modelled from its 33 m² EPC floor area, its 7 recorded sales and recent sales of comparable homes in HP1 1ER. 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. 7 sales are recorded for 11 The Square. 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 11 The Square was lodged in April 2019 at band D and is valid until April 2029. 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 11 The Square. 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 32 schools and 30 stops listed are measured in a straight line from HP1 1ER, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band: 11 The Square 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.
