How the estimate is made
The estimate for 21a is modelled from its 111 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SE1 4BF. 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.

Start your researchHow to read this page
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 21a is modelled from its 111 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SE1 4BF. 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. No sale is recorded for 21a, which usually means it hasn't changed hands since 1995 or the sale was not for value. 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 21a was lodged in February 2026 at band D and is valid until February 2036. Floor area, heating and insulation details on this page come from it.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 21a. 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 17 months, which places each incident at an approximate point. The 97 schools and 30 stops listed are measured in a straight line from SE1 4BF, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
