We are testing the UK’s Emergency Alerts system on Sunday 7 September at 3pm.
Emergency Alerts is a UK government system that provides warning and advice in a life-threatening emergency.
The government will be running a national test of the Emergency Alerts system on Sunday 7 September 2025.
The government does not need to know your phone number or location to send you an alert.
Reasons you might get an alert
You may get alerts about any type of life-threatening emergency, such as:
Wildfires, severe flooding, extreme storms,
What happens when you get an emergency alert
Your mobile phone or tablet may: make a loud siren-like sound, even if it’s set on silent. Vibrate, read out the alert. The sound and vibration will last for about 10 seconds.
An alert will include a phone number or a link to the GOV.UK website for more information.
You’ll get alerts based on your current location – not where you live or work. You do not need to turn on location services to receive alerts.If you cannot receive emergency alerts. If you do not have a compatible device, you’ll still be informed about an emergency. The emergency services have other ways to warn you when there is a threat to life.
If you’re deaf, hard of hearing, blind or partially sighted
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. For more information, go to:Â Gov.uk/alerts
