UK Emergency Alerts Service – National Test

On Sunday 23 April 2023 at 3pm, the UK government will be testing a new Emergency Alert system.

This service that will warn you if there is a danger to life nearby & in an emergency, your mobile phone or tablet will receive an alert with advice about how to stay safe. The government does not need to know your phone number or location to send you an alert.

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.

For more information about the alert please check the government website.
