Overview

About 9 Barnsbury Avenue

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

9 Barnsbury Avenue is a one-bedroom semi-detached house in Aylesbury (HP20 1NL). It has a recorded floor area of 43 m² (around 463 sq ft), construction records dating it to 1950-1966 and council tax band B. The latest certificate (May 2019) shows an E (score 50), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since December 2008. Between certificates, main heating went from Poor to Average; while hot-water efficiency dropped from Poor to Very Poor. The recommended improvements would lift it to C (score 75), a 2-band jump. Main heating runs on electricity. At 43 m² this is the 5th smallest of 29 units on EPC record in the building, where floor areas span 38–120 m². The building's EPC ratings span F to C across 29 units on file.

It hasn't traded since December 2002, a hold of 24 years that's notably long for the area. Today's modelled estimate of £163,000 sits 85.2% above the 2002 sale of £88,000. At 43 m² it sits well below the postcode median (70 m² across 28 EPCs), making it one of the more compact homes locally.

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 9 Barnsbury Avenue is modelled from its 43 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP20 1NL. 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 9 Barnsbury Avenue. 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 9 Barnsbury Avenue was lodged in May 2019 at band E and is valid until May 2029. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 9 Barnsbury Avenue. 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 18 months, which places each incident at an approximate point. The 27 schools and 30 stops listed are measured in a straight line from HP20 1NL, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
9 Barnsbury Avenue is in council tax band B. 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.
