The UK Government will send a test emergency alert to mobile phones across the UK at around 3 pm on 7 September 2025.

During the test, mobile phones will vibrate and make a loud siren sound for roughly 10 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. 

The test will be sent to approximately 87 million mobile phones in the UK.

It is important to test the system because alerts are used to warn if there’s a danger to life nearby, including extreme weather. They allow vital information to be sent to people rapidly in an emergency.
