The UK government is testing the Emergency Alerts system on Sunday 7 September 2025 at 3pm. Compatible mobile phones and tablets will receive an alert, make a loud siren-like sound and vibrate. You will not need to take any action.

The Emergency Alerts system is used to warn if there’s a danger to life nearby, including extreme weather. Regular testing ensures the system is functioning correctly, should it need to be used in a life-threatening emergency.

If you receive an alert while driving, do not pick up your phone and attempt to deal with the message. Continue driving as normal, staying in full control of your vehicle.
