The UK Government will be testing the Emergency Alerts system on Sunday 7 September at 3pm.

If you have a compatible mobile phone or tablet, you’ll receive an alert that will make a loud sound and vibrate. You don’t need to do anything when this happens.

The Emergency Alerts system is designed to keep people safe by warning about serious dangers nearby, such as extreme weather. Regular testing helps make sure the system works properly if it’s ever needed in an emergency.
