National Emergency Alert Test Run
Emergency Alert Test

Next Sunday, 23 April at 3pm, the Government is going to test the national UK Emergency Alert Service. What this means is that if you have a mobile or tablet on the 4G or 5G phone network, you will receive an alert. 

What will your mobile do when you get the emergency alert?

According to the UK government portal, 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.

According to the official website, the text you will see on your mobile device will look like this:  

“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 an actual emergency, follow the instructions in the alert to keep yourself and others safe.

Visit for more information.

This is a test. You do not need to take any action.”

There is no need to sign up to alerts. You will receive them automatically whether or not you are connected to mobile data or Wi-Fi. The Government Alert Service does not need your phone number or location to alert you. There is no charge to you for the service. Emergency alerts are free. 

Why is the Government doing this?

The emergency alert is a UK government service that issues warnings if there is a danger to life nearby. The Alert on April 23rd is a test so that everyone knows what to expect if ever the service was to be used ‘for real’. 

Future emergency alerts are only likely to be issued for extreme weather conditions, such as severe flooding or fires. Alerts will only be sent by the emergency services, government departments, agencies and public bodies that deal with emergencies.  

In a real emergency, your mobile device will receive an alert with advice about how to stay safe based on your current location, not where you live or work.
