When is the UK Emergency Alert System Test Happening?

Whether you’re quietly revising, working s part time shift, or simply enjoying a Sunday walk through your student city, a loud, unexpected alarm going off can be jarring. For most of the UK, that is exactly what will happen when the next UK Emergency Alert System Test takes place. Since it was first trialled in 2023, the system has been deemed a necessary tool in keeping the public safe and informed during really life emergencies.

The alert only last a few seconds but knowing why it’s happening (and how to prepare for the real thing) can help you avoid any confusion and ensure you’re expecting it come the next test. As a student living away from home for the first time it can be a scary thought, but being aware that this is one of the ways that the UK handles public safety is important for your peace of mind.

What is the UK Emergency Alert System?

The UK Emergency Alert System is a government run service that broadcasts vital safety messages to mobile phones within a pre-determined geographical area. It’s designed to inform the public quickly in the event of serious threats such as flooding, fires, or other safety related issues that could risk lives.

Here’s how it works:

• It uses both 4G and 5G mobile networks and does not factor in your mobile phone number or data plan.
• The system sends alerts to phones within a certain location range.
• The alerts occur automatically, so there’s no need to download any apps or sign up to email lists (be aware of any scams claiming you need to).

The UK isn’t the only country that has implemented the system in recent years. Nations such as Japan, the Netherlands, and the United States all do similar things. It ensures that if something dangerous happens near to your student accommodation, you’ll be informed within seconds.

When is the Next UK Emergency Alert System Test?

Mark your calendar, because the next nationwide test of the emergency alert system is set to take place on Sunday 7th September 2025 at 3:00 PM (BST). 

This national trial of the system had been planned to check that the alerts work effectively throughout the UK, across all regions and network providers.

📱What to expect at 3 PM on the day:

• Your mobile phone will emit a loud, siren like sound for around 10 seconds.
• The alert is designed to override any silent or do not disturb modes.
• A clear message will appear on your screen explaining that the alert is a test and that you do not need to do anything.
• You can manually dismiss the alert upon its activation by swiping it away and clicking “OK”.

Remember, it’s only a test. There’s no need to take any drastic action. It’s important not to ignore the alert, so that you can avoid any embarrassment if you’re sat in a quiet place at the time.

Will This Alert Affect You as a Student?

Yes. Whether you’re living in student accommodation, commuting into the city, or visiting friends elsewhere, the alert could briefly interrupt your Sunday afternoon.

Here a few ways your day could be impacted, and how you can plan around it:

• If you’re studying in the library or a public café, make sure to be ready to swipe away the alert as quickly as possible. It will come through any silent settings on your phone.
• For those in work, there’s a good chance you won’t have access to your phone during your shift. In this case, let the alert ring out along with the rest of your colleagues.
• If you’re travelling on public transport, the collective alarm might cause a stir for a few moments. It’s normal and should be expected.
• In spaces where silence is important, such as a faith service, then it could be wise to turn your phone off on this occasion as it will no longer come through.

Can I Turn it Off?

We wouldn’t advise doing so, but you can deactivate the emergency alert system through your phone’s settings.

The reason we would strongly recommend against turning it off is that this system was created to protect people from danger in everyday life. These warnings may seem trivial, but they could one day save lives and help you act quickly in a crisis.

If you are adamant that turning if off is what you want to do, here’s how:

iPhone users:

• Go to Settings > Notifications
• Scroll down until you find Emergency Alerts
• Turn them on or off here

Android users: 

• Navigate to Settings > Safety & Emergency or Wireless Emergency Alerts
• Look for Severe alerts or Extreme Threats
• Toggle your preferences accordingly

Why Does the UK Use Emergency Alerts?

As we’ve touched upon already, the UK Government introduced this system to provide timely warnings in times of public safety concern. There are a number of moments in which the system could be activated for real following the scheduled test.

• Flash floods following heavy rainfall
• Sudden chemical leaks, fires, or explosions
• Terror attacks or other threats to critical infrastructure
• Public health emergencies such as disease outbreaks

According to the the UK Government website, the test’s goal is to ensure that “the system is functioning correctly” so that is can be rolled out during any genuine threats to public safety. The latest test is part of an ongoing trial period that has been designed to ensure the system can be used nationwide across various types of device.

Information for International Students

Studying in the UK comes with plenty of new experiences, but moments like this can be daunting if you don’t have similar systems in your native country. It may feel like an invasion of your privacy, but here’s what you need to know.
