Nationwide Emergency Alert Test Set for September 7th
Millions of mobile phones across the UK will go off at 3pm on Sunday, September 7, as the government carries out its second-ever nationwide test of the Emergency Alerts system. The alert will cause phones to vibrate and play a loud siren-like sound for 10 seconds, even if they’re on silent. A message will pop up on the screen, clearly stating that it’s only a test and that no action is needed.
The system is designed to warn people about life-threatening situations, such as severe weather or major incidents, by sending real-time updates through 4G and 5G networks. It’s already been used five times since its first full-scale test in 2023, including during Storm Éowyn and the evacuation of 10,000 people in Plymouth after the discovery of a WWII bomb.
While officials stress the alerts can save lives, some concerns have been raised. Domestic abuse charities have warned that hidden phones could be discovered during the test, putting victims at risk, and there is also concern that people who are driving at the time could be startled, increasing the risk of accidents. The government has published guides on how to opt out, and the public information campaign ahead of the test includes support for vulnerable groups and resources in British Sign Language.
“This test is like a fire drill for the whole country,” said Pat McFadden, Chancellor of the Duchy of Lancaster. “It’s a vital part of building national resilience and making sure the system works when it matters most.”
