Method

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 15 Chantry Close is modelled from its 349 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in NN3 9EG. 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 15 Chantry Close. 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 15 Chantry Close was lodged in August 2016 at band B and expired in August 2026, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 2 applications are matched to 15 Chantry 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 16 months, which places each incident at an approximate point. The 18 schools and 30 stops listed are measured in a straight line from NN3 9EG, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
15 Chantry 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.
