UK Emergency Alerts System test
This is a general announcement to let you know that on 7 September 2025 at 3pm, the UK Government will be carrying out a national test of the Emergency Alerts system.
Emergency Alerts
Emergency Alerts is the UK government system that provides warning and advice in a life- threatening emergency.
The government will be running a national test of the system at 3pm on 7 September 2025. An alert will be sent to all compatible mobile phones and tablets across the UK.
The government does not need to know your phone number or location to send you an alert. You will get alerts based on your location not where you live or work and you do not need to turn on location services to receive alerts. You can opt out of the alerts.
When you get an alert, your mobile phone or tablet may:
- make a loud siren-like sound, even if it is set on silent
- vibrate
- read out the alert
If you have a vision or hearing impairment, audio and vibration attention signals will let you know you have an emergency alert if accessibility notifications have been enabled on your mobile phone or tablet device.
The alert message will confirm it is a test and you do not need to take any further action. You can confirm the alert is genuine on the GOV.UK website.
You can read more about the UK government Emergency Alerts Systems on the GOV.UK website.
