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. 2 sales are recorded for 12 Down Leaze. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC

The latest one for 12 Down Leaze was lodged in December 2008 at band D and expired in December 2018, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.

Area figures
