Valuation method in detail
How the estimate is made
The estimate for 18 Gratwicke Road is modelled from its 123 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in BN11 4BH. 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 18 Gratwicke Road. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC

Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 18 Gratwicke 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 16 months, which places each incident at an approximate point. The 20 schools and 30 stops listed are measured in a straight line from BN11 4BH, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
18 Gratwicke 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.
