Valuation method in detail
How the estimate is made
The estimate for 7 Grafton Close is modelled from its 120 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in CF23 9JA. 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. 3 sales are recorded for 7 Grafton Close. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 7 Grafton Close was lodged in June 2021 at band C and is valid until June 2031. 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 7 Grafton Close. 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. Schools and stops are measured in a straight line from CF23 9JA.
Council tax band
7 Grafton Close is in council tax band E. 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.
