- How the estimate is made
- The estimate for 12 South Dene is modelled from its 122 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in HP2 6HP. 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 South Dene. 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 12 South Dene was lodged in August 2025 at band E and is valid until August 2035. Floor area, heating and insulation details on this page come from it.
