Emergency Alert on Sunday 7 September 2025 at 3pm

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.
Comprehensive guidance on how to support the
campaign, including download links to relevant
assets, key messages and copy can be found on
GOV.UK.
