Emergency alert to be sent to smartphones in UK test

BRITAIN, SEP 7 – The UK government will test the emergency alert system on 87 million smartphones to ensure readiness for life-threatening events, following five prior regional activations since 2023.

  • The UK government will test its national emergency alert system on September 7, 2025, sending alarms to mobile phones nationwide at 3pm BST.
  • This follow-up test aims to improve system reliability and public familiarity after the initial nationwide drill in April 2023 revealed technical issues affecting some networks.
  • Compatible phones on 4G and 5G will vibrate, sound a 10-second siren even if silent, and display a message clarifying the alert is only a test, with the new test including British Sign Language support.
  • The alert system has issued five real emergency warnings to millions during events like Storm Eowyn affecting 4.5 million people and aided evacuations including 10,000 residents during a WWII bomb operation in Plymouth.
  • The test supports a wider resilience action plan investing billions in biosecurity and flood defenses and seeks to ensure the system works optimally while addressing concerns for vulnerable groups including domestic abuse victims.
