Valuation method in detail

How the estimate is made: The estimate for 23a is modelled from its 32 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SL1 2DA. 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. No sale is recorded for 23a, which usually means it hasn't changed hands since 1995 or the sale was not for value. 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 23a was lodged in July 2022 at band E and is valid until July 2032. 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 23a. 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 33 schools and 30 stops listed are measured in a straight line from SL1 2DA, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band: 23a 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.
