Overview

About Flat 1

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

Flat 1 is a one-bedroom detached house in Northampton (NN2 6BT). It has a recorded floor area of 40 m² (around 426 sq ft) and construction records dating it to 1900-1929. The latest certificate (December 2008) shows an E (score 50), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 75), a 2-band jump. Main heating runs on electricity. The latest certificate is from December 2008, so improvements made since then won't be reflected.

Across 1996–2006, sale prices on this property compounded at 14.8% per year. On a £-per-square-foot basis, the last sale (£458/sq ft) was about 315.8% above the typical sold price in the postcode.

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 Flat 1 is modelled from its 40 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in NN2 6BT. 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. 2 sales are recorded for Flat 1. 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 Flat 1 was lodged in December 2008 at band E and expired in December 2018, 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. None is matched to Flat 1. 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 31 schools and 30 stops listed are measured in a straight line from NN2 6BT, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
