Around 4.6 million properties are at risk of flash flooding, which occurs when drainage systems are overwhelmed by rainwater, an increase of 43% from the 2018 assessment. “These changes are almost entirely due to significant improvements in the Environment Agency’s data, modeling and use of technology, which enable a more accurate assessment of flood risk,” said the Agency.

Furthermore, around 3,500 properties will be located in areas at risk of coastal erosion by 2055. This figure will exceed 10,000 by the end of the century, according to analyzes by the Coastal Coast Agency. environment.
