New UK Emergency Alerts service
On Sunday 23 April 2023 at 3pm, there will be a national test of the new UK Emergency Alerts service.
Emergency Alerts is a UK government service to warn you via your mobile phone or tablet of a danger to life nearby, such as severe flooding, or other dangers to life, health or property in the area you're located.
In an emergency, alerts would be sent to all compatible 4G and 5G mobile phones within an area of risk. They don't track your location, need your phone number, or collect personal data. Only the government and emergency services will be able to send them.
If you don't have a mobile phone, you'll still be kept informed through other channels, such as local news, radio, television and social media.
If you get an Emergency Alert on your phone, you'll hear a loud, siren-like sound. A message on your screen will tell you about the emergency and how best to respond. You can check an alert is genuine.
On Sunday 23 April, there will be a national test of the Government's UK Emergency Alerts Service. If you receive an alert, read it carefully and follow the instructions.
