Description, fields, and how we track updates on the provider’s site.
Description
The British Geological Survey (BGS OpenGeoscience) provides open access to a range of geoscience datasets focused on geological risk factors impacting UK properties.
Key datasets include radon gas potential maps, mining hazard data (covering coal, tin, salt and historical mines), ground stability information related to subsidence, hydrogeology, and superficial deposit thickness.
These datasets are primarily utilised by environmental search companies, insurers, conveyancers, and property professionals who require detailed ground condition and risk assessments.
Data can be accessed via the BGS OpenGeoscience web portal and through APIs, with datasets freely available under an open licence.
Data types
Key data fields
- Radon Gas PotentialEstimated radon gas risk levels across Great Britain relevant to property health and safety assessments.
- Mining Hazard AreasLocations and extents of historical and active mining sites, including coal, tin and salt mines affecting ground stability.
- Ground Stability / Subsidence RiskInformation on areas potentially affected by ground movement and subsidence, crucial for structural risk analysis.
- HydrogeologyDetails on groundwater presence and behaviour that may influence property foundations and flood risk.
- Superficial Deposit ThicknessData on the depth and composition of superficial deposits impacting soil properties beneath buildings.
Update frequency
Data is periodically updated by BGS, with revisions published as new geological information becomes available.
