Phone numbers in flood risk areas

Your phone number has been added to our basic flood warning service because it's been registered to an address in a flood risk area. 

Mobile and landline phone operators have provided the numbers for at-risk properties, giving us the opportunity to reach people who may not know about our free flood warning service. 

Personal information

If you've received a message about being added to the service, we do not know your name or address.

When you sign up to the full flood warning service we will record your name, address and contact details.

The Environment Agency manages the flood warning systems that we use. Their privacy notice explains how they deal with your information. Natural Resources Wales can only process the personal data for customers in Wales. See our privacy notice.

Understanding your flood risk

If you have been added to the service this means that your address is in a flood risk area. It does not mean that a flood is currently expected.
