How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
How the estimate is made
The estimate for Cornwall House 55 57 is modelled from its 65 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SL1 1DZ. 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 Cornwall House 55 57, 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 Cornwall House 55 57 was lodged in May 2016 at band D and expired in May 2026, so a new one is needed to sell or let. 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 Cornwall House 55 57. 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 32 schools and 30 stops listed are measured in a straight line from SL1 1DZ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
