Working with mobile broadcasting technology, the Emergency Alerts system will transform the UK’s warning and informing capability; providing a means to get urgent messages quickly to nearly 90 percent of mobile phones in a defined area; providing clear instructions about how best to respond.
The system is now ready to be tested across the country following successful tests in East Suffolk and Reading, as the Government continues to strengthen its resilience capability, making sure it offers the best possible protection against an ever-evolving range of threats.
A UK-wide alerts test will take place in the early evening of Sunday 23 April which will see people receive a test message on their mobile phones.
The alerts will only ever come from the Government or emergency services, and they will issue a warning, always include the details of the area impacted, and provide instructions about how best to respond - linking to gov.uk/alerts where people can receive further information.
Emergency Alerts will be used very rarely - only being sent where there is an immediate risk to people’s lives - so people may not receive an alert for months, or even years.
The service has already been used successfully in a number of other countries, including the US, Canada, the Netherlands and Japan, where it has been widely credited with saving lives, for example, during severe weather events. In the UK, alerts could be used to tell residents of villages being encroached by wildfires, or of severe flooding.
By broadcasting from cell towers in the vicinity of an emergency, the alerts are secure, free to receive, and one-way. They do not reveal anyone’s location or collect personal data. Alerts can only be sent by authorised Governmental and Emergency Services users. Successful live tests of the service have already taken place in East Suffolk and Reading.
