JBA's UK flood data is the UK’s leading tool for flood insurance underwriters, providing high-resolution hazard maps of multiple flood types. Since their first release in 2008, the UK maps benefit from several years of updates, feedback and validation against flood claims. Modelled in JFlow (JBA Risk Management's own highly acclaimed 2D hydraulic model that currently has some 300,000 stream processors in the grid), the hazard maps form part of our UK probabilistic model, and can be used to derive other datasets such as annual damage ratio data.

At 5m resolution the UK flood maps cover six flood perils throughout Great Britain (river, coastal, surface water, groundwater, canal failure and dam break) and three in Ireland (river, coastal and surface water). They remains an invaluable tool for gauging where flooding is likely to occur, right down to individual property level information
