Essentials

Emergency alerts, radio and failed networks

A useful information plan combines Emergency Alerts, local responders, radio, paper contacts and a family check-in rule. No single channel is guaranteed.

Last checked: 25 August 2026 How we use official sources

Understand UK Emergency Alerts

  • Compatible phones in an affected area receive cell-broadcast alerts without registration.
  • The system does not need your phone number or location history.
  • An alert can sound even when a phone is on silent.
  • Alerts may cover severe flooding, extreme storms, wildfires and other dangers to life.
  • Alerts do not replace local radio, television, news, emergency services or council information.

Create a communications fallback

  • Write important numbers, addresses, medical information and radio frequencies on paper.
  • Choose an out-of-area contact and two meeting points.
  • Agree when to send a short text instead of repeatedly calling.
  • Keep a battery or wind-up radio and charge power banks before forecast disruption.
  • Pre-register for EmergencySMS if you need to contact 999 by text, or install 999 BSL if appropriate.

Verify before sharing

  • Find the original source and check the place, time and exact instruction.
  • Distinguish a live order or warning from general planning advice.
  • Do not forward screenshots without a source link and timestamp.
  • If the internet fails, use radio and information from responders in your area.
