A test of the UK’s “national warning message” system will be conducted in the next few weeks.

A disaster alert that warns the public about the outbreak of war or a pandemic will be tested for the first time within weeks.

A “national warning message” will be sent directly to every mobile phone across Britain later this month or in early March.

Before the alert is sent a publicity campaign will warn people to expect it and not to panic when they get it.

Officials say the test may be the only time a nationwide message is sent but it will demonstrate that the new system is capable of reaching every part of the country.

Alerts can also be limited to specific areas by controlling which mobile phone masts they broadcast from. In practice the system is expected to be used for local “extreme weather warnings” such as flood alerts.

The Government previously sent out a national text message at the start of the Covid crisis in March 2020, ordering people to stay at home, but this was only possible with assistance from mobile phone operators. Rather than sending a text, the new emergency alert uses an app included in Android and Apple iPhone operating systems.

This can be turned off in phone settings, although it is thought many phone owners won’t even know they have it installed.

One of the benefits is that the system is not affected by the number of people making phone calls, which is likely to increase if they believe an emergency is imminent.

The message can include a link to a website which provides more information. A source said: “Hopefully this will be the only time we ever need to send a nationwide message.”

There will be “a very high threshold” for issuing an alert which will only happen if lives are at risk, officials say.

Existing methods of contacting the public, such as by text or phone messages and alerts on television or radio, will also continue to be used.

The new alerts are a 21st century equivalent of the former three minute warnings of a nuclear attack during the Cold War.
