Ministers say the alerts could save lives by giving people crucial warnings when danger is near

It will happen at 3pm on Sunday, September 7, with the system expected to reach around 87 million devices across the UK.
Ministers say the alerts could save lives by giving people crucial warnings when danger is near, similar to systems already used in countries like the US and Japan.
Cabinet minister Pat McFadden said: 'Emergency Alerts have the potential to save lives, allowing us to share essential information rapidly in emergency situations including extreme storms. Just like the fire alarm in your house, it's important we test the system so that we know it will work if we need it."
The last nationwide test in 2023 saw mobiles across the UK blare out the alert, and since then, the system has been triggered during major storms, floods, and even when a World War II bomb was discovered in Plymouth.
In January this year, 4.5 million people in Scotland and Northern Ireland received an alert as Storm Éowyn battered the UK with a red weather warning in place.
During Storm Darragh last December, 3.5 million people in Wales and the South West got an alert — the storm killed two people.
Police say the alerts were vital during the Plymouth evacuation, when more than 10,000 people were moved after the discovery of an unexploded bomb.
Tracey Lee, Chief Executive of Plymouth Council, said: "It played a vital role in helping us safely evacuate over 10,000 people and coordinate a complex, multi-agency response."
Assistant Chief Constable Glen Mayhew added: 'By their nature, emergency incidents occur with very little notice. They can develop at speed and across wide areas which puts lives at risk. This system has the ability to send an alert to those whose lives may be at risk, to ensure they can act to help themselves and others."
The alerts work on all 4G and 5G networks, but phones must be switched on to receive them.
Special guidance is being issued to victims of domestic abuse with hidden phones, who may need to opt out to stay safe.
The message sent on September 7 will clearly state it is only a test.
The test comes alongside wider government plans to boost the UK's resilience — including £1.3 billion for new biosecurity centres, £4.2 billion for flood defences, and the biggest pandemic exercise in Britain's history, dubbed Exercise Pegasus.

New hosepipe ban announced as temps to hit 31C in UK this week – check 9 rules to follow
Parts of the country are expected to meet heatwave criteria THIRST TRAP New hosepipe ban announced as temps to hit 31C in UK this week – check 9 rules to follow Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) A NEW hosepipe ban has been announced as temperatures are set to hit 31°C later this week. Yorkshire Water announced the hosepipe ban would come into effect on Friday, July 12. Sign up for Scottish Sun newsletter Sign up 2 Watering the garden or washing the car with a hosepipe will be restricted Credit: Getty Brits will not be permitted to use hosepipes to water their gardens, wash their cars or for any other purpose while the ban is in effect. Businesses will still be permitted to use a hosepipe if it relates to commercial purposes. Blue badge holders and people on Yorkshire Water's priority services register will also be exempt from the restrictions. Restrictions are set to stay in place until the region has seen some rainfall but the ban could last until winter. It comes as Yorkshire reservoirs reached 55.8 per cent, 26.1 per cent lower than usual for this time of year. A particularly warm spring is blamed for lowering the reservoir levels. Temperatures this week are set to skyrocket again with London due to reach 31°C on Friday according to the Met Office. A yellow heat health alert has been issued for parts of England as temperatures are forecast to soar in the coming days. The UK Health Security Agency alert will come into place at 10am on Wednesday and continue until 10am next Tuesday for the East Midlands, West Midlands, East of England, London, the South East and the South West. It comes as the Met Office said temperatures in some parts of the UK could surpass 30C - meeting the criteria for a heatwave - by the end of the week. The hot weather has parched the land and drained reservoirs across the country as UK hit with hosepipe bans The Met Office warned that several areas of the UK could reach their respective criteria for a heatwave later in the week. Temperatures across the nation are expected to climb into the low 30s. Deputy Chief Meteorologist Dan Holley explains: 'High pressure from the Atlantic will gradually exert its influence over the UK this week. "We'll see temperatures build day-on-day, with the potential for hot conditions to become quite widespread by the end of the week and into the weekend. 'On Wednesday, temperatures could reach up to 28°C in parts of England, climbing to 30°C on Thursday and 32°C by Friday. "By this stage, heatwave criteria are likely to be met in parts of England and Wales, and in parts of Scotland over the weekend. 'High temperatures are likely to persist into the weekend, especially away from coasts with onshore winds, reaching the low 30s in portions of England and Wales, and accompanied by rising humidity and warmer nights. 2 Brits will be asked not to use their hosepipe Credit: Getty 'This heatwave is likely to last longer than previous ones so far this summer, and affect a wider area, with the focus for some of the highest temperatures displaced across more central and western areas at times. "In addition, pollen and UV levels will also be very high in some areas.' Yorkshire Water's director of water, Dave Kaye, said: "Introducing these restrictions is not a decision we have taken lightly, and we've been doing everything we can to avoid having to put them in place. "Our region experienced an extremely dry spring, which resulted in the region entering drought status in June. "Usually, spring is a time when our groundwater sources and reservoirs continue to be topped-up by changeable weather, but this has not been the case in 2025, with our reservoir stocks falling since the last week of January."

Date when armageddon siren will sound on all UK phones in emergency alert test
Mobile phones across the country will blast out a loud siren this September as part of a nationwide emergency alert test designed to save lives in real disasters. Mobile phones across the UK will emit a loud, unavoidable siren at 3pm on Sunday, September 7, as part of a nationwide test of the Government's emergency alert system. The alarm, which will sound for around 10 seconds even if phones are on silent, is part of a drill to prepare for real-life emergencies. A warning message will flash on screens, clearly stating it's just a test, and users can simply swipe it away or press 'OK', reports the Mirror. This marks the second national test of the system, first rolled out in 2023 and since used five times to alert the public during extreme weather and other life-threatening events. Pat McFadden, Chancellor of the Duchy of Lancaster, said: 'Emergency alerts have the potential to save lives. They allow us to quickly share vital information in dangerous situations, such as severe storms. 'Just like a fire alarm at home, testing ensures the system works when we need it most.' One of the largest real uses of the alert was during Storm Eowyn in January 2024, when 4.5 million people in Scotland and Northern Ireland were warned following a red weather warning. Another 3.5 million received alerts during Storm Darragh, while messages were also sent during flash flooding in Cumbria and Leicestershire. The alert system was also activated in Plymouth earlier this year when a World War II bomb was discovered, helping officials evacuate over 10,000 people. Tracey Lee, Chief Executive of Plymouth City Council, said the alert played a 'vital role' in coordinating the emergency response. Similar systems operate in countries like Japan, the US, and Germany, with Finland running monthly national tests. Join the Daily Record WhatsApp community!

A public awareness campaign will launch ahead of the UK-wide test, with special attention to vulnerable groups, including domestic abuse survivors. While the alerts are strongly recommended for everyone, the Government has confirmed it is possible to opt out—particularly for those who may be put at risk by a sudden alert sound. Campaigners have previously raised concerns the siren could expose people with hidden phones to abusive partners. The test comes as the Government publishes a new strategy to improve the UK's readiness and response to national emergencies. Ministers are also releasing an update on the 2023 Biological Security Strategy, aimed at better pandemic preparedness.

Emergency texts with 'loud siren' to be sent out in Glasgow
Mobile phone users will receive a test emergency alert around 3pm on Sunday, September 7, as part of plans to strengthen the country's preparedness. The devices will vibrate and make a loud siren noise for roughly 10 seconds, even if they are set to silent. This allows vital information and advice to be sent to people rapidly in an emergency. The system is used to warn if there's a danger to life nearby, including extreme weather. It allows vital information and advice to be sent to people rapidly in an emergency. It will be just the second of its kind and follows a government commitment to test the system regularly to make sure it works optimally and familiarise the public with the alerts. This is in line with standard practice in other countries, such as Japan and the USA. READ NEXT: New plan revealed for historic Glasgow pub - here are the details Pat McFadden, Chancellor of the Duchy of Lancaster, said: 'Emergency alerts have the potential to save lives, allowing us to share essential information rapidly in emergency situations, including extreme storms. "Just like the fire alarm in your house, it's important we test the system so that we know it will work if we need it. 'This test is part of our action plan to build resilience across the whole country and secure the nation under the Plan for Change - from the £1 billion we're investing in a new network of National Biosecurity Centres to the £4.2 billion we're investing to build a new generation of flood defences to protect local communities.' Since the first national test of the emergency alert system in April 2023, five alerts have been sent, including during major storms when lives were at risk. The largest ever use of the system saw approximately 4.5 million people in Scotland and Northern Ireland - including Glasgow - receive an alert during Storm Eowyn in January 2025, after a red weather warning was issued, meaning there was a risk to life.
