Emergency Alerts Test – Helping You Prepare for Sunday 7 September 2025 at 3pm

Published on 28 August 2025 09:10 AM

At 3pm on Sunday 7 September, the UK Government will be running a nationwide test of the Emergency Alerts system.

This system is designed to warn people about life-threatening emergencies such as severe flooding, wildfires, and extreme weather.

What you can expect

  • Your phone or tablet may emit a loud siren, vibrate, and read out a message.

  • This will happen even if your device is on silent.

  • The alert will last for around 10 seconds and will include a link or number for further information.

Preparing for the test

  • The sound can be startling, so it may help to remind yourself that this is only a test.

  • If you live with or care for someone who may be more vulnerable, you might want to let them know in advance.

  • If you are affected by domestic abuse and have a second or hidden phone, turn it off before the test. You can also opt out of receiving alerts altogether: www.gov.uk/alerts/opting-out.

  • A short video guide is available here: Managing Emergency Alerts on your phone to stay safe if you’re experiencing domestic abuse – YouTube.

If you are driving

  • Do not check your phone when the alert sounds.

  • Stop safely and legally if you need to, or listen to live radio for updates.

This is a test only. The Emergency Alerts system has been created to help keep people safe in real emergencies.
