Overview

About Lewis House

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

Lewis House is a semi-detached house in Isham, Kettering, Kettering (NN14 1HX). It has a recorded floor area of 50 m² (around 538 sq ft) and construction records dating it to 1983-1990. At 50 m² this is the smallest unit on EPC record across Lewis House (50–80 m²). The building's EPC ratings span D to C, with this unit at the top. On EPC score it ranks first in the building (70 versus a worst of 59). The latest certificate (October 2016) shows a C (score 70). Main heating runs on electricity.

It hasn't traded since April 2008, a hold of 18 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 50 m² it sits well below the postcode median (76 m² across 14 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 79% of similar EPCs). Across 1997–2008, sale prices on this property compounded at 6.6% per year. Today's modelled estimate of £123,000 is 43% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£160/sq ft) was about 16.9% below the postcode norm.

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 Lewis House is modelled from its 50 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in NN14 1HX. 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 Lewis House. 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 Lewis House was lodged in October 2016 at band C and expired in October 2026, 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 Lewis House. 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 7 schools and 30 stops listed are measured in a straight line from NN14 1HX, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
