The government will be carrying out a national test of the UK Emergency Alerts system on 7 September 2025 at 3pm.

The test alert will be sent to all compatible 4G and 5G mobile phones and compatible tablets across the UK. The test is not intended to alert you to real danger and you will not need to take any further action.

The emergency alert looks and sounds very different to other types of messages you might receive on your phone. You’ll hear a loud, siren-like sound and your phone or tablet will vibrate.

The alert system is in place to warn people if there’s a danger to life nearby, such as flooding or fires. This Sunday is SIMPLY A TEST - do not panic!

Those who wish to opt-out, e.g. abuse survivors who might have a phone hidden, can do so by following the instructions here: https://www.womensaid.org.uk/uk-emergency-alerts/
