Yiewsley Climate Risk Data

Yiewsley is a settlement in Greater London, within Hillingdon council area. This page shows flood, heat, air quality, and subsidence risk data for Yiewsley, drawn from official UK government sources. LocalRisk tracks 12 postcodes within Yiewsley.

Yiewsley has moderate flood risk based on Environment Agency NaFRA2 data. 17.3% of postcodes in Yiewsley fall into high or higher flood risk bands, with a further 12.4% at medium risk and 70.3% at lower risk. Flood risk at street level can differ significantly from these area-wide averages — elevation, proximity to watercourses, and local drainage all affect individual postcode risk bands. Check a specific postcode above for your exact Environment Agency flood risk rating.

Heat risk in Yiewsley is moderate under current projections. Met Office UKCP18 data suggests around 39 days above 25°C per year in this area by the 2021-2040 period (central estimate, high emissions scenario). These are probabilistic projections — actual outcomes depend on future emissions levels. Properties in Yiewsley without adequate ventilation or insulation may face increasing summer heat stress and higher cooling costs as temperatures rise.

Air quality in Yiewsley averages 8.2 µg/m³ PM2.5, which is elevated — above the WHO annual mean guideline of 5 µg/m³. Defra UK-AIR monitoring data underpins this figure. PM2.5 levels are typically higher near busy roads, industrial areas, and dense urban centres, and lower in parks, green corridors, and residential backstreets.

Subsidence data for Yiewsley is sourced from the British Geological Survey GeoSure dataset, which maps clay shrink-swell risk across Great Britain. In areas with shrink-swell clay, foundations can shift as soils dry out in summer and re-wet in winter. Properties built before 1980 on clay-rich ground are most exposed. Check a specific postcode for Yiewsley for a property-level subsidence risk band.
