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 8 Heol Y Dderwen. 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 8 Heol Y Dderwen was lodged in October 2010 at band F and expired in October 2020, so a new one is needed to sell or let.
