Overview

About 18 Bibury Crescent

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

18 Bibury Crescent is a two-bedroom detached house in Northampton (NN3 6AG). It has a recorded floor area of 85 m² (around 915 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (June 2009) shows an E (score 50), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 66). The latest certificate is from June 2009, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history. The home occupies a cul-de-sac position.

Untraded for 17 years, with the last transfer in October 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 85 m² the property is well over the postcode median (65 m² across 29 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 76% of similar EPCs). Across 1999–2009, sale prices on this property compounded at 5.9% per year. Today's modelled estimate of £256,000 sits 89.6% above the 2009 sale of £135,000. On a £-per-square-foot basis, the last sale (£148/sq ft) was about 28.1% below the postcode norm. One planning record on file: an extension approved in 2017. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.

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 18 Bibury Crescent is modelled from its 85 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in NN3 6AG. 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 18 Bibury Crescent. 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 18 Bibury Crescent was lodged in June 2009 at band E and expired in June 2019, 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. 1 application is matched to 18 Bibury Crescent. 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 30 schools and 30 stops listed are measured in a straight line from NN3 6AG, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
18 Bibury Crescent is in council tax band C. 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.
