The UK Government will be testing the UK Emergency Alert system on the 7th of September 2025 at 15:00 (3:00 PM)
The government will be testing the Emergency Alerts system this Sunday, and your phone is likely to make a loud noise even if it’s on silent. Here’s everything you need to know about what’s happening and why.
What is the Emergency Alerts test?
On Sunday 7 September 2025 at 3pm, the government will carry out a national test of the Emergency Alerts system. This means most mobile phones and tablets across the UK will receive a test message, accompanied by a loud siren-like sound and vibration that will last for about 10 seconds.
The message you receive will clearly state that this is a test and that no action is required on your part. The alert will come through even if your device is set to silent mode, which is an important feature of the system designed to ensure people receive warnings in genuine emergencies.
