Our Annual Damage Ratio data enable technical risk pricing at an individual property level over a 10,000-year period, allowing you to select the right price for the risk identified and compare risk profiles.

Analytics To Manage
Your Flood Risk

Our flood analytics assist with risk reflective pricing at an individual property level to provide a yearly technical price, expressed as an Annual Damage Ratio (ADR).

The data uses flood frequency, flood severity, defence information and property vulnerability analysis to produce a unique flood risk profile at each location. ADR uses our flood maps to estimate the full range of possible flood severities over a 10,000-year period at each location. This approach provides a sufficient range of flood hazard to derive an annualised cost of flooding at an individual location level.

ADR data, coupled with our flood maps, enable underwriters to set the right price for the risk identified, adopt a more competitive pricing structure and compare risk profiles globally.

ADR data are immediately available for the UK and Canada and are in development for the US based on 5m mapping. Due to our global coverage of mapping, ADR data can be generated for other countries on request.

Our flood analytics are platform agnostic and available to use in-house or via our many resellers.
