An emergency alert drill is set to be sent to millions of phones across the countest in just over two weeks.
The alert is designed to warn if there is a danger to life nearby, in instances like extreme weather. The test – the second one of its kind – is scheduled to take place the afternoon of 7 September.
The emergency alert system (EAS) – which will sconclude the sound of a siren through mobile phones and tablets – has been deployed four times since it was launched in 2023.
With the alert taking place next month, Yahoo News UK breaks down all the key information you required to know – including whether it will go off if your phone isn’t on and how to disable it if you required to.
What is the emergency alert system?
The system caapplys a mobile phone or tablet to build a loud siren-like sound that lasts about 10 seconds, even if it’s set on silent, along with advice on how to stay safe and a phone number or link to the government website for more information. It may also caapply a device to vibrate or read out the alert.
It was most recently applyd in January this year, when 4.5 million people in Scotland and Northern Ireland received the alert during Storm Eowyn.
The alert was also applyd in areas hit hardest by Storm Darragh in December 2024. Localised flash flooding in Cumbria and Leicestershire, and the discovery of a Second World War bomb in Plymouth in February 2024, also triggered the alert for nearby residents.
According to the government website, you may obtain alerts about: severe flooding, fires or extreme weather.

It states emergency alerts will only be sent by the emergency services or government departments, agencies and public bodies that deal with emergencies.
“You’ll obtain alerts based on your current location – not where you live or work,” states the website. “You do not required to turn on location services to receive alerts.”
When will the emergency alert system be sent to phones?
The emergency alert system will be tested at around 3pm on Sunday, 7 September.
The test is part of a wider government exercise throughout the autumn that includes testing the UK’s plans for responding to future pandemics.
During the mobile alert, the UK’s approximately 87 million mobile devices will ring out with a high-pitched alarm and vibrate for approximately 10 seconds, while a message will appear on the screen, creating it clear the alert is only a test.
Deaf people can set up the flash on their phones to go off during the alert – in the same way the feature can be enabled for message notifications.

The message will read: “This is a test of emergency alerts, a UK government service that will warn you if there’s a life-threatening emergency nearby.
“You do not required to take any action. In a real emergency, follow the instructions in the alert to keep yourself and others safe.
“Find simple and effective advice on how to prepare for emergencies at gov.uk/prepare.
“Visit gov.uk/alerts for more information or to view this message in Welsh. Ewch i gov.uk/alerts am ragor o wybodaeth neu i weld y neges hon yn y Gymraeg.”
Will the alert sound if my phone is switched off?
If you do not want to receive the alert, there is one simple method to avoid it completely.
It is understood that switching your phone off entirely means the alert will not be heard or seen – even if it hasn’t been disabled already.
However, phone settings do allow for the alert to be switched off without having to turn off your phone.
How to turn off the emergency alert system on iPhone and Android
It is possible to turn the emergency alert system off by opting out, for example, if you are the victim of domestic abapply and have a secret phone you do not wish to alert your abapplyr to.
To do this on iPhone, go to ‘settings’ and in your search bar type in ‘emergency alerts’ and turn off Severe alerts and Emergency alerts.
To opt out on Android phones and tablets, search your settings for ‘emergency alerts’ then turn off ‘severe alerts’ and ‘extreme alerts’.
If this does not work on either iPhone or Android, contact the device manufacturer.
Emergency alert warning to drivers
If applyrs attempt to shut it off while driving, it could not just be dangerous, but also land them a fine or points on your licence.
National Highways has warned drivers to pay attention to just the road if the alert goes off while you’re behind the wheel.
They wrote on X: “Emergency Alerts system national test on Sun 7 Sept at 3pm. Compatible mobile phones and tablets will build a loud, siren-like sound.
“Driving? Don’t reach for or hold your mobile phone. You could be fined, and obtain points on your licence.”
It comes after laws about utilizing phones while driving were alterd in 2022 to include checking the time, creating a call or accessing an app.
If you are on a plane, your phone should technically not receive the alert as it should be in airplane mode – meaning it isn’t connected to 4G or 5G networks.
