Grimsby and Cleethorpes Flood Sirens

The Environment Agency’s old coastal flood sirens will stop being used from 31 December 2020.

The 18 flood sirens were originally installed after the Environment Agency’s free Flood Warning Service was first launched in 2006 because this didn’t have the capacity to reach all properties at coastal flood risk.

This service has been much improved since then and is now available for all properties at risk of tidal and/or river flooding here. The flood warnings can be issued in a more targeted way, and can give information much sooner, to help communities be prepared.

The EA can already reach 83% of properties at risk of coastal flooding with a flood warning message through this service. The sirens only have an audible range that could reach 72% of properties at risk, depending on factors like wind direction and double-glazing too.   

Make sure your home or business is fully signed up to this free service. Call 0345 988 1188 or do it online here

There is lots of information available to help you make a flood plan for your home business or a community group. Find out more about the decommissioned flood sirens.

If you have any questions, please contact the Environment Agency’s Flood Resilience Team by email or call 03708 506 506.
