About 7 Blackwell Hill
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
7 Blackwell Hill is a three-bedroom detached house in Northampton (NN4 9YB). It has a recorded floor area of 74 m² (around 797 sq ft), construction records dating it to 1983-1990 and council tax band C. The latest certificate (November 2013) shows an E (score 51), well below the UK norm with real room to improve. Earlier certificates rated it D (May 2009); the latest reading is one band lower. Between certificates, window efficiency went from Average to Good, lighting went from Very Poor to Average and main heating went from Average to Good; while roof efficiency dropped from Average to Very Poor. The recommended improvements would lift it to B (score 85), a 3-band jump. The latest certificate is from November 2013, so improvements made since then won't be reflected.
It hasn't traded since April 1998, a hold of 28 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £276,000 sits 311.9% above the 1998 sale of £67,000. On a £-per-square-foot basis, the last sale (£84/sq ft) was about 49.7% below the postcode norm. At 74 m² it's 19.4% smaller than the typical home in the postcode (92 m² median across 25 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs).

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 7 Blackwell Hill is modelled from its 74 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in NN4 9YB. 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 7 Blackwell Hill. 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 7 Blackwell Hill was lodged in November 2013 at band E and expired in November 2023, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. None is matched to 7 Blackwell Hill. 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 15 months, which places each incident at an approximate point. The 17 schools and 30 stops listed are measured in a straight line from NN4 9YB, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 7 Blackwell Hill 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.
