It has a recorded floor area of 117 m² (around 1259 sq ft), construction records dating it to 1991-1995 and council tax band D. The latest certificate (August 2015) shows a C (score 69), just inside the C band. The recommended improvements would push it to B (score 81).

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 17 Alder Close is modelled from its 117 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SO40 4YS. 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 17 Alder 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 17 Alder Close was lodged in August 2015 at band C and expired in August 2025, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 17 Alder 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 12 months, which places each incident at an approximate point. The 4 schools and 30 stops listed are measured in a straight line from SO40 4YS, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
17 Alder Close is in council tax band D. 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.
