A UK-wide test of the Emergency Alerts system is scheduled for Sunday 7 September 2025 at around 3pm — your phone may sound a loud siren and vibrate for up to 10 seconds, followed by a message explaining it is a drill. The national test helps check the system so it works fast when lives are at risk.

How the emergency alert system works (plain and simple)

Emergency Alerts use a technology called cell broadcast: mobile masts in an affected area send a single short message that reaches compatible 4G and 5G phones nearby. You do not need to have mobile data or an app installed to receive a message — and the service is free. The system is intended for truly life-threatening events and can target small geographical areas so only people at risk are warned.

Why it matters

The system has been used in real emergencies — for example to warn people during severe storms and when an unexploded World War II bomb was found in Plymouth — demonstrating how mobile alerts can reach people quickly and save lives. Regular emergency drills help test coverage, delivery times and public understanding.

Are we ready? Common practical limits

• Not every phone will get alerts: some older models or devices without recent software updates may not receive cell broadcast messages. Check your device’s compatibility and update its operating system when possible.
• You can opt out: both iPhone and Android let you switch off ‘Severe’ or ‘Extreme’ alerts in settings, though experts advise keeping them enabled for safety.

Step-by-step guide: what to do before, during and after an alert

• Before the test:check compatibility: go to your phone settings and look for Emergency Alerts (or Severe/Extreme Alerts). Update your OS if updates are available.
• Make a family plan: agree on a meeting point, an out-of-area contact and a simple checklist (medications, important documents, charger).
• During an alert: read the message quickly and follow official instructions (evacuate, shelter, avoid an area). If you’re driving, do not handle your phone — stop safely first.
• Keep emergency info handy: local radio stations, council webpages and the gov.uk alerts page list fuller guidance. Save key contacts and local shelter locations in your phone.
• After the alert: check official channels for updates before returning to normal activity and share accurate information with family and neighbours.
