Flooding: information to support constituents before, during and after

Published 16/12/2025

Natural Resources Wales (NRW) estimates that almost 273,000 properties are at risk of flooding in Wales. This is approximately one in seven properties across the country.

This number is projected to rise as we see an increase in the frequency and intensity of extreme weather events, including storms and prolonged wet periods.

This webpage provides links to useful information to help Senedd Members and their staff support constituents before, during and after a flood.
