Overview

About 21 Cottesbrooke Gardens

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

21 Cottesbrooke Gardens is a four-bedroom detached house in Northampton (NN4 0DE). It has a recorded floor area of 155 m² (around 1668 sq ft), construction records dating it to 1996-2002 and council tax band E. The latest certificate (June 2015) shows an E (score 52), well below the UK norm with real room to improve. Earlier certificates rated it D (March 2009); the latest reading is one band lower. Between certificates, lighting went from Average to Good; while wall efficiency dropped from Good to Very Poor. The recommended improvements would lift it to C (score 79), a 2-band jump. The latest certificate is from June 2015, so improvements made since then won't be reflected. The home occupies a cul-de-sac position.

At 155 m² the property is well over the postcode median (105 m² across 38 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 87% of similar EPCs). Across 1998–2012, sale prices on this property compounded at 4.9% per year. Today's modelled estimate of £421,000 sits 99.5% above the 2012 sale of £211,000. 14 years since the last transfer (October 2012).

Method

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 Cottesbrooke Gardens is modelled from its 155 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in NN4 0DE. 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 Cottesbrooke Gardens. 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 Cottesbrooke Gardens was lodged in June 2015 at band E and expired in June 2025, 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 21 Cottesbrooke Gardens. 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 18 schools and 30 stops listed are measured in a straight line from NN4 0DE, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Cottesbrooke Gardens is in council tax band E. 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.
