Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for Flat C is modelled from its 43 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SE21 8EA. 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 Flat C. 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 Flat C was lodged in September 2024 at band C and is valid until September 2034. 6 certificates are on record, which shows how the home has changed.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. None is matched to Flat C. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
- Crime is police-recorded street-level data over the last 18 months, which places each incident at an approximate point. The 60 schools and 30 stops listed are measured in a straight line from SE21 8EA, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
