About 17 Blackwell Hill
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
17 Blackwell Hill is a four-bedroom detached house in Northampton (NN4 9YB). It has a recorded floor area of 90 m² (around 969 sq ft), construction records dating it to 1983-1990 and council tax band D. The latest certificate (June 2011) shows a D (score 67), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 69). The latest certificate is from June 2011, so improvements made since then won't be reflected. Other recorded features include a conservatory.
It hasn't traded since July 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 1996–2008, sale prices on this property compounded at 10.2% per year. Today's modelled estimate of £309,000 sits 60.9% above the 2008 sale of £192,000. On a £-per-square-foot basis, the last sale (£198/sq ft) was about 18.6% above the typical sold price in the postcode. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and partial demolition, meaningful when judging how the property has evolved.

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 17 Blackwell Hill is modelled from its 90 m² EPC floor area, its 3 recorded sales 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. 3 sales are recorded for 17 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 17 Blackwell Hill was lodged in June 2011 at band D and expired in June 2021, 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. 2 applications are matched to 17 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
- 17 Blackwell Hill is in council tax band D. 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.
