About 17 Cowgill Close
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
17 Cowgill Close is a five-bedroom semi-detached house in Northampton (NN3 8PB). It has a recorded floor area of 115 m² (around 1238 sq ft), construction records dating it to 1967-1975 and council tax band B. The latest certificate (April 2026) shows a C (score 75), near the top of the C band. When first surveyed in August 2013 the rating was D, the property has climbed 1 band since. Between certificates, lighting went from Poor to Good; while wall efficiency dropped from Good to Very Poor. This certificate was lodged in the last six months, so the rating reflects current condition. Records show the property has been extended at some point in its history. The home occupies a cul-de-sac position.
Untraded for 25 years, with the last transfer in March 2001. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 115 m² the property is well over the postcode median (72 m² across 24 EPCs), placing it in the larger end of the local stock. 5 bedrooms is on the larger side for this postcode, where 3 is the typical count. Today's modelled estimate of £301,000 sits 370.3% above the 2001 sale of £64,000. On a £-per-square-foot basis, the last sale (£52/sq ft) was about 67% below the postcode norm. One planning record on file: an extension approved in 2020. Past consents include an extension, meaningful when judging how the property has evolved.

- How the estimate is made
- The estimate for 17 Cowgill Close is modelled from its 115 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in NN3 8PB. 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 Cowgill Close. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC

- Area figures
