⚠️ Government Emergency Alert Test – What You Need to Know if You’re Affected by PTSD or C-PTSD
On Sunday 7th September 2025, there will be a nationwide test of the UK Government’s Emergency Alerts system. This test is designed to trial the system used to warn people about life-threatening emergencies like severe flooding, fires, or extreme weather events.
As part of the test, your mobile phone or tablet may make a loud, siren-like sound, even if it’s set to silent. It will also vibrate and display a message on your screen. The alert will last for around 10 seconds.
Why we’re sharing this
We know that sudden, unexpected noises - especially those that sound like alarms - can be distressing or triggering for people living with PTSD or C-PTSD.
Many people with PTSD or C-PTSD experience hypervigilance, a state of being constantly alert and on guard, always scanning the environment for potential threats. Loud sounds, abrupt vibrations, or unexpected messages can understandably cause feelings of fear, panic, or flashbacks.
That’s why we want to make sure you have the chance to prepare, plan, and protect your wellbeing, especially if you think this alert might affect you.

What to expect on 7th September
If your device is compatible and the alerts are switched on, it may:
🔊 Make a loud, siren-like sound (even on silent mode)
📳 Vibrate
📱 Display a message on your screen, including a link or phone number for more info
The alert will last for about 10 seconds, and there’s no action required from you during the test.
Can I turn the alert off?
Yes, you can opt out of emergency alerts on most devices - and we’ve included clear instructions in our article to help you do this, if you feel it’s necessary for your wellbeing.
Please note, for your safety, we don't suggest you turn the notifications off. Emergency alerts contain life-saving information and should be kept switched on for your own safety. But we always advise people to make informed decisions that feel right for them.
You can read step-by-step guidance for iPhones, Androids, and other devices on our article.
A gentle reminder
We aren’t able to answer questions about the Emergency Alert system itself - this is a government-led initiative. But we’re sharing this information to ensure you’re not caught off guard, and so you have the tools to make the right choice for your own safety and peace of mind.
