How the estimate is made
The estimate for 20 Calton Avenue is modelled from its 48 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SE21 7DQ. 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 20 Calton Avenue is modelled from its 48 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SE21 7DQ. 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 20 Calton Avenue, 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 20 Calton Avenue was lodged in March 2016 at band E and expired in March 2026, so a new one is needed to sell or let. 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 20 Calton Avenue. 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 67 schools and 30 stops listed are measured in a straight line from SE21 7DQ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 20 Calton Avenue is in council tax band C. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
