UK to Test Emergency Alert System Nationwide Again

The UK government will conduct another nationwide test of its emergency alert system later in 2025, sending a loud 10-second siren to all mobile phones to warn of life-threatening emergencies like extreme weather, disasters, or national security threats. The system, introduced in 2023, will be tested biennially, with the next test’s date yet to be confirmed. The initiative comes amid heightened global tensions, especially following recent unrest in Iran, leading to a focus on public vigilance and readiness. Across Europe, the EU is advising its 450 million citizens to stockpile emergency supplies and prepare for crises including war, cyber-attacks, natural disasters, and pandemics. Officials emphasize that during actual emergencies, people should follow the alert’s instructions. The alert message during the test will clarify that it is only a trial and no action is needed.
