- 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 17 Clos Ty Mawr. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
