Overview

About 21 Birchfield Road

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

21 Birchfield Road is a one-bedroom mid-terrace house in Northampton (NN1 4RF). It has a recorded floor area of 192 m² (around 2067 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (September 2017) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 83), a 2-band jump.

It hasn't traded since June 2007, a hold of 19 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. At 192 m² the property is well over the postcode median (130 m² across 26 EPCs), placing it in the larger end of the local stock. Across 1997–2007, sale prices on this property compounded at 14% per year. Today's modelled estimate of £373,000 is 30.2% above the 2007 sale price.

How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
Valuation method in detail
How the estimate is made
The estimate for 21 Birchfield Road is modelled from its 192 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in NN1 4RF. 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 Birchfield Road. 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 Birchfield Road was lodged in September 2017 at band D and is valid until September 2027. Floor area, heating and insulation details on this page come from it.
Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 21 Birchfield Road. 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 33 schools and 30 stops listed are measured in a straight line from NN1 4RF, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Birchfield Road 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.
