Valuation method in detail
How the estimate is made
The estimate for 49 Napsbury Lane is modelled from its 250 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in AL1 1DU. 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 49 Napsbury Lane. 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 49 Napsbury Lane was lodged in March 2026 at band B and is valid until March 2036. 3 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 4 applications are matched to 49 Napsbury Lane. 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 15 months, which places each incident at an approximate point. The 26 schools and 30 stops listed are measured in a straight line from AL1 1DU, not by walking route.
Council tax band
49 Napsbury Lane is in council tax band G. 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.
