Government Emergency Alert System - test on 23 April

Published: Tuesday, 11 April 2023

On Sunday April 23, 2023, there will be a national test of the UK Emergency Alerts service.

Emergency Alerts is a new UK government service that will warn you if there’s a danger to life nearby.

In an emergency, your mobile phone or tablet will receive an alert with advice about how to stay safe. If you receive an alert, read the alert carefully and follow the instructions.

Emergency Alerts are sent to compatible mobile phones within an area of risk. They don’t track your location, need your phone number, or collect personal data, and only the emergency services can send them. You can check an alert is genuine at

An Emergency Alert is a loud, siren-like sound with a message on your screen.
