Public Testing of the UK Emergency Alerts System

National Test Scheduled for 7 September 2025

The UK government has confirmed that a national test of the Emergency Alerts system will take place on Sunday 7 September 2025 at 3pm.

The alert will be sent to all compatible 4G and 5G mobile phones and tablets across the country, including here in Leicester and Leicestershire. This follows the first successful national test in April 2023.

Why Is the Test Happening?

Emergency Alerts are designed to keep the public safe by warning of life-threatening events such as:

• Severe flooding

• Fires

• Public health emergencies

Regular testing helps ensure the system works properly if it is ever needed in a real emergency.

The government has made information about the test available in British Sign Language (BSL) and Easy Read formats, ensuring accessibility for all.

What to Expect

On the day of the test, your phone or tablet will:

• Emit a loud, siren-like sound

• Display a clear message on screen

• Vibrate for around 10 seconds

This alert will look and sound different from other notifications, so it will be immediately recognisable. If you have a vision or hearing impairment, the combination of audio and vibration signals is designed to ensure the alert is noticed.

Do You Need to Do Anything?

No action is required. The test is not a real emergency, and the message will disappear once the alert finishes.

Can You Opt Out?

It is possible to opt out of receiving Emergency Alerts, including this test. However, the government advises keeping them switched on, as they could provide crucial information that helps keep you safe in a genuine emergency.
