Tomorrow afternoon, Sunday 23 April 2023 at 3pm, there will be a national test of the UK Emergency Alerts service. 'Emergency Alerts' is a UK government service that will warn you if there's a danger to life nearby. In an emergency, your mobile phone or tablet will receive an alert with advice about how to stay safe.
The government does not need to know your phone number or location to send you an alert. You may get alerts about: severe flooding, fires or extreme weather. Emergency alerts will only be sent by the emergency services or government departments, agencies and public bodies that deal with emergencies
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.
