UK Government to test emergency alert system on Sunday, 7 September
The system is designed to warn people about serious, life-threatening situations, such as extreme weather events. It allows emergency services and government agencies to send urgent safety information quickly to anyone in danger.
What to expect during the test
On 7 September, if your phone is switched on and connected to a mobile network, it will:
- Make a loud siren-like sound for about 10 seconds, even if it’s set to silent
- Vibrate
- Show a message stating this is only a test
The test alert will not need any action, and the government does not need your phone number or location to send it.
Who sends emergency alerts?
If you receive a real emergency alert, these will only be sent by:
- Emergency services
- Government departments, agencies, and public bodies responsible for managing emergencies
Information for British Sign Language users: National Emergency Alert BSL - English Version
Opting out of emergency alerts
While alerts are designed to keep you safe and should remain switched on, you can opt out if necessary.
For example, victims of domestic abuse with a hidden phone may wish to disable them.
How to opt out
iPhone
- Open Settings > Notifications
- Scroll to the bottom
- Switch off Severe Alerts and Extreme Alerts

Other devices
Depending on your phone’s manufacturer or software version, settings may be under:
- Messages > Message Settings > Wireless Emergency Alerts
- Settings > Sounds > Advanced > Emergency Broadcasts

Once there, turn off Severe Alerts, Extreme Alerts, and Test Alerts.
If alerts still appear after opting out, contact your device manufacturer for support.
