Valuation method in detail

How the estimate is made: The estimate for 12 Heol Dewi Sant is modelled from its 89 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SA4 9BD. 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 12 Heol Dewi Sant. 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 Heol Dewi Sant was lodged in March 2020 at band D and is valid until March 2030. 2 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 12 Heol Dewi Sant. 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 14 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from SA4 9BD.
Council tax band: 12 Heol Dewi Sant is in council tax band B. 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.
