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 12a is modelled from its 47 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SE18 6LF. 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 12a, 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 12a was lodged in July 2023 at band C and is valid until July 2033. 3 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 12a. 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 17 months, which places each incident at an approximate point. The 39 schools and 30 stops listed are measured in a straight line from SE18 6LF, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
