UK Emergency Alerts

Emergency Alerts are messages sent to all compatible 4G and 5G mobile phones when there’s a danger to your life, health or property in the area you’re located.



Emergency Alerts is a service provided by the UK government to warn you if there’s a danger to life nearby.

When there’s an emergency, your mobile phone or tablet will receive a notification, accompanied by a loud siren-like sound, with guidance on how to remain safe.

The government does not require your phone number or location information to send you a notification.

Circumstances in which you might receive a notification include:

  • Significant flooding
  • fires
  • extreme weather conditions.

Emergency notifications will only be issued by:

  • Emergency services
  • government departments, agencies, and public bodies responsible for emergency management.

What happens when you get an emergency alert

Your mobile phone or tablet may:

  • Make a loud siren-like sound, even if it’s set on silent
  • vibrate
  • read out the alert.

The sound and vibration will last for about 10 seconds.

An alert will include a phone number or a link to the GOV.UK website for more information.

You’ll get alerts based on your current location – not where you live or work. You do not need to turn on location services to receive alerts.
