National test of the UK Emergency Alerts service.

On Sunday 23 April 2023 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.

Reasons you may get an alert include:

  • severe flooding.
  • fires.
  • extreme weather.

Emergency alerts will only be sent by the emergency services or Government departments, agencies and public bodies that deal with emergencies.

When you get an alert your mobile phone or tablet may:

  • make a loud siren-like sound even if it’s set on silent.
  • vibrate for around 10 seconds.
  • read out the alert.

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’re deaf, hard of hearing, blind or partially sighted have a vision or hearing impairment the audio and vibration attention signals will let you know you have an emergency alert.

You can opt out of emergency alerts but you should keep them switched on for your own safety.

To opt out search your settings for ‘emergency alerts’ and turn off ‘severe alerts’ and ‘extreme alerts’. However if you still get alerts contact your device manufacturer for help.
