newGeoSure Insurance Product: Natural Ground Movement Risk for Great Britain Postcodes

Biannually updated data from the British Geological Survey, this dataset provides a derived product for insurance risk assessment. It evaluates the combined potential impact of six geological hazards—landslides, shrink-swell clays, soluble rocks, running sands, compressible ground, and collapsible deposits—on low-rise buildings at a postcode level across Great Britain. The product is created using statistical analyses and expert elicitation techniques and is designed for use at a 1:50,000 scale.

Use Cases

• Identifying property insurance risk based on postcode-level geological hazard susceptibility.
• Estimating susceptibility to natural ground movement for actuarial modeling.
• Spatial analysis of regional exposure to shrink-swell clays or landslides.
• Incorporating geological risk factors into property valuation models.

Strengths

• Covers six specific geological hazards: landslides, shrink-swell clays, soluble rocks, running sands, compressible ground, and collapsible deposits.
• Provides national coverage across Great Britain.
• Updated biannually with new releases of Ordnance Survey Code-Point data.
• Designed for a 1:50,000 scale, providing 50-meter ground resolution.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset has been superseded, according to the description.
