Emergency Alerts System Test – Sunday 7 September at 3:00 PM
The UK Government will be conducting a nationwide test of the Emergency Alerts System on Sunday 7 September at 3:00 PM.
This system is intended to provide urgent warnings in situations where there is a risk to life, such as during severe weather events or other emergencies. Routine testing is essential to ensure the system operates effectively should it be required in a real-life scenario.
Key details of the test:
The alert will be sent to compatible mobile phones and tablets.
Devices will emit a loud, siren-like sound, even if set to silent.
The alert will also vibrate and may read out the message aloud.
The alert will last for approximately 10 seconds.
No action is required from recipients.
Please let elderly or vulnerable friends, family and neighbours know that this is happening so as not to alarm them.
