The UK Government will be testing the Emergency Alerts system on Sunday 7 September at 3pm.
Your mobile phone or tablet will vibrate and make a loud siren-like sound, even if it’s set on silent. The alert message will confirm this is a test and that you do not need to take any further action.
Regular testing ensures the system is functioning correctly, should it need to be used in a life-threatening emergency.
You can opt out of the Emergency Alerts, including the national test, but you should keep them switched on for your own safety.
Please note that the national alert will also sound on devices that are set to silent; the only way to stop the national alert sounding on a device is to either opt out of Emergency Alerts or turn the device off for a period of time prior to and after the scheduled test.
