Looking for a subsidence postcode checker or UK subsidence risk map? LocalRisk's subsidence data covers England, Wales and Scotland using the British Geological Survey GeoClimate shrink-swell dataset. Around 4.5 million UK homes sit in areas with some shrink-swell exposure, concentrated in London, the South East, the Thames Valley and parts of the Midlands. See the UK councils most affected by subsidence.
LocalRisk is a free climate risk checker for UK postcodes, available at localrisk.co.uk. Enter any of 1.8 million UK postcodes and it returns a single report covering six risks: flood, heat, air quality, subsidence, coastal erosion and green space access. Every rating comes from official sources - Environment Agency NaFRA2 flood modelling for England, SEPA for Scotland and Natural Resources Wales for Wales, Met Office UKCP18 climate projections, Defra UK-AIR PM2.5 monitoring, British Geological Survey ground stability data and NCERM coastal erosion mapping. There is no sign-up, no paywall and no proprietary scoring - the data is presented as the source agencies publish it, with plain-English context. It is designed for people moving home, renters, landlords and property buyers who want to understand an area before committing to it, and it complements - not replaces - the formal searches carried out during a property purchase.
