About 6 Bostock Avenue
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
6 Bostock Avenue is a four-bedroom mid-terrace house in Northampton (NN1 4LW). It has a recorded floor area of 125 m² (around 1349 sq ft), construction records dating it to 1900-1929 and council tax band C. The latest certificate (January 2009) shows an E (score 51), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since January 2009. Between certificates, roof efficiency went from Average to Good. The latest certificate is from January 2009, so improvements made since then won't be reflected. Other recorded features include a basement. The home occupies a cul-de-sac position.
Last sold in July 2018, so it's been off the market for around 8 years. Across the public record there are 6 sales, relatively high churn for a single property.

Today's modelled estimate of £329,000 is 16.5% above the 2018 sale price. On a £-per-square-foot basis, the last sale (£209/sq ft) was about 61.1% above the typical sold price in the postcode.

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 6 Bostock Avenue is modelled from its 125 m² EPC floor area, its 6 recorded sales and recent sales of comparable homes in NN1 4LW. 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. 6 sales are recorded for 6 Bostock 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 6 Bostock Avenue was lodged in January 2009 at band E and expired in January 2019, 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 6 Bostock 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 NN1 4LW, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 6 Bostock 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.
