UK Government new Emergency Alerts System

The UK government’s new Emergency Alerts system is now live.  The system will enable people to be contacted via their mobile phone when lives are in danger. 

Emergency Alerts are sent to compatible mobile phones within an area  of risk.  They don’t track your location, need your phone number, or collect  personal data, and only the emergency services can send them.  An Emergency Alert is a loud, siren-like sound with a message on  your screen.  If you receive an alert, read the alert carefully and follow the instructions. You can check an alert is genuine at

You can opt out of receiving emergency alerts; for more information on how to opt out please go to

If you don’t have a mobile phone, you’ll still be kept informed through other channels. To find out more about Emergency Alerts, visit

On Sunday 23 April 2023 at 3pm, there will be a national test of the Emergency Alerts service.

A UK-wide alerts test will take place at 15.00 on Sunday 23 April which will see people receive a test message on their mobile phones.
