About 21 Byron Street
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
21 Byron Street is a three-bedroom mid-terrace house in Northampton (NN2 7JE). It has a recorded floor area of 81 m² (around 872 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (October 2022) shows a D (score 64), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since September 2009. Between certificates, roof efficiency went from Very Poor to Average and lighting went from Poor to Very Good; while window efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 82), a 2-band jump.
It hasn't traded since October 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Across 2000–2009, sale prices on this property compounded at 6.8% per year. Today's modelled estimate of £207,000 sits 68.3% above the 2009 sale of £123,000.

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 21 Byron Street is modelled from its 81 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in NN2 7JE. 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 21 Byron Street. 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 21 Byron Street was lodged in October 2022 at band D and is valid until October 2032. 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 21 Byron Street. 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 35 schools and 30 stops listed are measured in a straight line from NN2 7JE, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 21 Byron Street is in council tax band B. 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.
