Please note the following news item concerning flood sirens within Grimsby & Cleethropes.

If further information is needed, please contact me, or Karl at Big Local, Cleethorpes.


Good morning,

I am contacting you regarding the future of the Grimsby and Cleethorpes flood sirens to seek your support.

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/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.

We are planning to stop using the sirens from 31 December 2020. Please see the attached briefing note for more details.

We would like to seek the North East Lincolnshire Neighbourhood Watch Network’s support to help raise awareness about this, and also our Flood Warning Service, in the community. I have attached two versions of a poster and Flood Action Guide leaflet to help with this.

The Flood Warning Service already reaches 83% of properties at risk of coastal flooding with a flood warning message. This compares with an audible range for the sirens of 72%.

We would appreciate your thoughts and ideas about how we can increase the number of properties signed up to the Flood Warning Service still further. It is really easy to sign up to the Flood Warning Service. People can just call 0345 988 1188, or do it online

If you would like hard copies of either poster or leaflet, please contact our Flood Resilience Team using or call me on 07388 852117.

Grimsby and Cleethorpes are also being specifically targeted with social media messages this month to encourage people to know as part of our national annual Flood Action Campaign. If you have social media channels please help us to share any content you see more widely. More information is available here.

We would sincerely appreciate any other suggestions on how we can best raise awareness currently in these unprecedented times and look forward to hearing from you.

Kind regards,


Samantha Jeeawock
