Instantly assess flood risk to individual properties

FloodScore™ provides instant, cost-effective property-level flood risk scores and information for all properties in England, Scotland, Wales and Northern Ireland. The data enables businesses or users to quickly evaluate and quantify flood risk and is available as an online checking service or as an easy to integrate database. 

The product uses the same advanced flood modelling techniques that are used by some of the UK’s major insurers, and integrates the most complete and up-to-date flood and building stock data available.

FloodScore™ gives its user the ability to quantify the likelihood of an individual property being flooded due to rainfall, overflowing rivers or tidal surges. The results include a range of return periods and also provide the likely depth of the flood waters for each of these periods.

To make it easy to use, each property has a single overall score which classifies the flood risk as being negligible, minimal, moderate, high or extreme. Reports can be saved and printed for future reference, and the search history makes your due diligence easy to audit.
