GeoSmart GW5 is the definitive groundwater flood risk map data with unparallelled detail for clearer decisions

With groundwater flooding costing the UK economy £210million a year, there has been a clear need for better defined data at a property level. Our market leading 5m map dataset addresses this need directly.

Combining comprehensive data on geology, permeability and historic groundwater levels, it advances data insight to reveal risk of groundwater flooding rather than potential susceptibility.

The new 5m map dataset also incorporates the new 5m digital terrain model (DTM) to deliver enhanced resolution at the property scale, with the latest ‘state of the art’ LIDAR data from the Environment Agency. It reveals the complex relationship between terrain and “ponding” of groundwater in specific locations.

By offering better granularity of risk boundaries, topography and integration with other 5m surface and fluvial flooding datasets, the map provides far more ‘real world’ clarity than ever before. It will deliver address level insight which will have significant implications in terms of insurance premium calculations, land and property resilience planning and conveyancing due diligence.

  • Datasets can be integrated to property assets on a bespoke level.
  • Enhanced property information data as part of conveyancing due diligence
  • Integrated to insurance risk assessment.


  • Greater confidence in knowing individual conditions than ever before.
  • More informed choices for the property, infrastructure and insurance industries
  • Greater clarity on groundwater flood risk for property information providers
  • Property specific analysis to give property buyers, lenders and solicitors confidence
  • Important preparation support for emergency response, flood mitigation and land-use planning, as well as the assessment of climate change impact for property asset managers
