About 9 Chartwell Avenue
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
9 Chartwell Avenue is a three-bedroom semi-detached house in Northampton (NN3 6NT). It has a recorded floor area of 60 m² (around 641 sq ft), construction records dating it to 1967-1975 and council tax band C. The latest certificate (October 2010) shows a C (score 69), just inside the C band. The latest certificate is from October 2010, so improvements made since then won't be reflected.
Untraded for 15 years, with the last transfer in June 2011. Today's modelled estimate of £259,000 sits 67.1% above the 2011 sale of £155,000. On a £-per-square-foot basis, the last sale (£242/sq ft) was about 37.4% above the typical sold price in the postcode. At 60 m² it sits well below the postcode median (139 m² across 12 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 75% of similar EPCs). One planning record on file: an extension approved in 2011.

Start your researchHow to read this page
Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 9 Chartwell Avenue is modelled from its 60 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in NN3 6NT. 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 Chartwell 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 Chartwell Avenue was lodged in October 2010 at band C and expired in October 2020, 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 9 Chartwell 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 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 6NT, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 9 Chartwell Avenue 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.
