Mobile phones in the UK will be sent a test Emergency Alert at around 15:00 on Sunday 7th September 2025, as part of plans to strengthen the country’s preparedness.

The Emergency Alerts system is used to warn if there’s a danger to life nearby, including extreme weather. It allows vital information and advice to be sent to people rapidly in an emergency.

During the test, mobile phones will vibrate and make a loud siren sound for roughly ten seconds, even if they are set to silent. A message will also appear on phone screens, making it clear the alert is only a test.
