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 21 Blackthorn Close is modelled from its 44 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CB4 1FZ. 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 21 Blackthorn 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 21 Blackthorn Close was lodged in October 2021 at band C and is valid until October 2031. 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 21 Blackthorn 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 13 months, which places each incident at an approximate point. The 24 schools and 1 stop listed are measured in a straight line from CB4 1FZ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band: 21 Blackthorn Close is in council tax band B. 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.
