Overview

About 15 Cowley Close

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

It has a recorded floor area of 96 m² (around 1033 sq ft), construction records dating it to 1950-1966 and council tax band D. The latest certificate (May 2012) shows an F (score 37), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 77), a 3-band jump.

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 Cowley Close is modelled from its 96 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in HP22 5DQ. 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 15 Cowley 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 Cowley Close was lodged in May 2012 at band F and expired in May 2022, 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 15 Cowley 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 13 months, which places each incident at an approximate point. The 19 schools and 30 stops listed are measured in a straight line from HP22 5DQ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
15 Cowley 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.
