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 13 St Mellons Road. 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 13 St Mellons Road was lodged in September 2013 at band D and expired in September 2023, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
