Frequently asked questions

How does air quality affect property value?
Research from King's College London shows that properties in areas with poor air quality sell for 2–4% less than comparable properties in cleaner areas. The effect is strongest in urban areas near major roads. HouseCheckup's IQ Score factors air quality into the overall property assessment.
What air quality data does HouseCheckup use?
HouseCheckup uses DEFRA's background air pollution maps, which model PM2.5, NO₂, PM10, SO₂, and ozone concentrations across the UK at a 1km grid resolution. This is the same data used by local authorities for Air Quality Management Areas (AQMAs).
