The UK government is testing the Emergency Alerts system on Sunday 7 September 2025 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. Find out more at gov.uk/alerts.
You can opt out of the Emergency Alerts, including the national test, but you should keep them switched on for your own safety. Emergency Alerts will warn you via your mobile or tablet if there's a life-threatening emergency nearby. Only the government and the emergency services are able to send them.
There are simple and effective steps we can all take to be more prepared for an emergency.
Visit gov.uk/prepare for advice on how you can prepare.
