UK Prepares for Nationwide Emergency Alert Test in 2025
This year, every mobile phone across the UK will receive a loud, 10-second emergency alert as part of a government-led nationwide test. First introduced in 2023, the Emergency Alert System is designed to warn the public swiftly during serious threats such as severe weather or other life-threatening emergencies.
What to Expect from the Alert
When the test is conducted, phones will emit a distinctive alarm sound accompanied by a strong vibration — even if devices are set to silent or Do Not Disturb mode. Alongside the siren, a message similar to the previous 2023 test will appear, stating:
“Severe Alert. This is a test of Emergency Alerts, a new UK government service that will warn you if there’s a life-threatening emergency nearby. In a real emergency, follow the instructions in the alert to keep yourself and others safe. Visit gov.uk/alerts for more information. This is a test. You do not need to take any action.”
The system also delivers messages in Welsh when appropriate to support inclusivity across the UK.
Why the System Matters
The Cabinet Office emphasizes that these alerts are not meant to cause alarm or panic, but rather to ensure citizens receive timely warnings so they can act swiftly to protect themselves during emergencies. Since its rollout, the system has been successfully used in two real-life alerts, including severe weather warnings linked to Storm Darragh in late 2024.
Technical Notes and Network Challenges
The inaugural test in 2023 faced some hiccups; some users on major networks like Three Mobile reported not receiving the alert. Network operators explained that varying speeds across their infrastructure could affect delivery timing. The government and mobile providers continue working together to iron out these issues and improve reliability ahead of the upcoming test.
Advice for Drivers Receiving Alerts
Safety experts urge motorists to exercise caution upon receiving the alert while driving:
- Do not interact with your phone while behind the wheel.
- Find a safe and legal place to stop before reading the message.
- If unable to stop safely, listen to live radio for updates instead.
Using a handheld device while driving remains illegal, so prioritizing road safety above all is critical.
Controlling Alert Notifications
While the alert system is vital for public safety, individuals can opt out of receiving these notifications if desired. Here’s how:
- Apple devices: Go to Settings > Notifications, then scroll down to Extreme and Severe Alerts and toggle them on or off.
- Android devices: Navigate to Settings, search for Emergency Alerts, and toggle off alerts for extreme and severe threats.
However, bear in mind that disabling these alerts also means missing potentially life-saving notifications in genuine emergencies.
Looking Ahead: Frequency of Tests
The government plans to conduct emergency alert tests at least once every two years to maintain public awareness and system readiness. Though the exact date for this year’s test is yet to be revealed, authorities assure it will be widely communicated in advance.
Stay Prepared, Stay Safe
As the UK strengthens its emergency communication infrastructure, these alerts are set to become a crucial tool in protecting lives and enhancing national resilience during crises. By familiarizing yourself with how the system works — and following official guidance — you can ensure you’re ready to respond calmly and effectively when that alarm sounds.
