How to read this page

Where every figure above comes from, how current it is and what it can't tell you.

Valuation method in detail

How the estimate is made: The estimate for 9 Derwen Road is modelled from its 81 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in SA8 3AU. 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 9 Derwen Road. 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 9 Derwen Road was lodged in March 2021 at band E and is valid until March 2031. Floor area, heating and insulation details on this page come from it.
Planning records: Planning applications are collected from local authority registers through PlanIt. None is matched to 9 Derwen Road. 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 12 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from SA8 3AU.
Council tax band: 9 Derwen Road 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.
