Slightly Anxious is here to help you turn any crisis into a manageable adventure — for you and everyone you care about.

It is just after seven o'clock on a Friday evening, you are doing something entirely unremarkable — putting the bins out, watching the athletics, arguing gently with someone about what to have for dinner — and then every phone in the room starts making a noise you have never heard before, all at slightly different moments, and none of them stop for about ten seconds.

That happened to most of England and Wales on Friday 14th August, and judging by the reaction it startled an awful lot of people considerably more than the message itself warranted. So this is the calm version: what that noise actually was, why you got it, whether the government was right to send it, and — the important bit — what you should do the next time it happens, because there will be a next time and the next one may not be about barbecues.

What the alert actually said

The message was short, and worth reading properly now that you are not standing in a kitchen wondering whether the house is on fire:

"There is a very high risk of wildfires nationally. Residents, landowners and visitors should not undertake any activity that could start a fire, including disposable barbecues, firepits, garden incinerators or fireworks. Even a small flame can rapidly develop into a major wildfire placing lives, homes, businesses and emergency responders at risk. Follow official updates and report signs of fire immediately by calling 999."

It was sent by the Cabinet Office at 7.01pm and stopped sending at 11pm, and it went to England and Wales only, which is why your cousin in Glasgow was baffled when you rang her about it. It came at the end of a genuinely awful week in which a grass fire at Stourbridge destroyed 19 homes and damaged 18 more, a child and three firefighters were taken to hospital, and major incidents were declared in South Wales with around 200 military personnel deployed to help. The government also banned the sale of disposable barbecues (temporarily, and under review at the time of writing), and the Prime Minister described the country as a "tinderbox". By the government's own account, crews were tackling 43 wildfires on the Friday alone and had declared 11 major incidents, which it said was "stretching resources to the very limit". And these were not all remote moorland fires happening somewhere in the distance — one of them was at Hornchurch Country Park, which is an ordinary bit of green space with ordinary houses around it, and that is rather the point.

So the backdrop was real, and it was not a drill.

What an Emergency Alert actually is — and it is not a text message

This is the part almost nobody explains, and it is genuinely worth understanding, because a system you understand is a system you will not be frightened by.

An Emergency Alert is not a text. Nobody has your number, nobody looked you up, and no database anywhere has "Sarah, GU21" against a phone. The system uses something called cell broadcast, which means the message is transmitted by the mobile masts themselves to every compatible handset currently connected to them. It is closer to a radio station than to a text message — the mast simply shouts, and every phone in earshot hears it. That is why you will get an alert based on wherever you happen to be standing rather than where you live, and it is also why you do not need location services switched on for it to reach you.

A few other things worth knowing, because they are the things people ask us:

It overrides silent mode. This is deliberate and it is the whole point. An alert that politely respects your Do Not Disturb setting at three in the morning is an alert that does not work.
It lasts about ten seconds. Siren, vibration, and on some handsets it reads itself aloud.
Only a short list of bodies can send one — the emergency services, and government departments and agencies that deal with emergencies. Your energy supplier cannot send you one, and neither can anybody selling anything.
It will never ask you for anything. No links to click for a form, no details to confirm, no payment. If you get an email or a text claiming to be from Emergency Alerts, it is a scam, and you should report it rather than engage with it.
It does not replace the radio. The government says so itself. If the mobile network is down — and in a serious enough emergency it will be — the alert cannot reach you at all.

That last point is the one we would underline twice, and we will come back to it.

Why this one felt different — because it was

The system has only been used for real a handful of times since it launched, and every previous use followed the same shape: a specific danger, in a specific place, sent to the people standing in it. Around 3.5 million people in Wales and the South West during Storm Darragh in December 2024. Around 4.5 million in Scotland and Northern Ireland during Storm Eowyn in January 2025, which was the biggest use until now. An unexploded wartime bomb in Plymouth. Flash flooding in Cumbria and in Leicestershire.

Friday's alert was a different animal in two ways. Firstly it went to an entire country rather than to a hazard area, which is a jump from four and a half million people to something closer to sixty million. And secondly — this is the more interesting difference — it did not tell you that you were in danger. It asked you not to do something that might put somebody else in danger. Every previous alert said "this is coming for you, here is what to do." This one said "please don't light that."

That is not a small distinction, and it is the reason the argument started roughly four minutes after the sirens stopped.

So was the government right to send it?

We are going to give you both sides properly, because we think you are perfectly capable of forming your own view and we would rather you had the arguments than our verdict.

The case against is essentially about the threshold. The published purpose of the system is to warn you about an immediate danger to life nearby, and for the overwhelming majority of the people whose phones went off on Friday there was no immediate danger anywhere near them. The Conservative MP Alex Burghart pointed out that the system was set up on the explicit promise of "a very high threshold for its use based on strict criteria centred on an immediate risk to life," and asked the government to publish who authorised this one and against what criteria. That is not merely a political objection either, because Frazer Rhodes, one of the architects of the system itself, said the alert "really has divided opinion" and that the government ought now to set out the criteria for when it will and will not be used. There were also two real-world consequences that rather prove the point: fire and rescue services in Gloucestershire and Surrey both had to publicly ask people to stop calling 999 about neighbours having barbecues, and — much more seriously — a noticeable number of people responded to the alert by going into their settings and switching Emergency Alerts off altogether.

The case for is that wildfire is the one emergency where the people receiving the message are also the cause of it. You cannot ask the public to switch off a storm, and there would be no point trying. You can absolutely ask sixty million people not to light a disposable barbecue on the driest ground in fifty years, and if even a modest fraction of them listen then some number of fires simply never happen. It is also worth knowing that the government reportedly considered sending targeted alerts to the highest-risk regions and then widened it, not because the risk had spread, but because the fire services were running out of capacity to fight the fires they already had. Read plainly, that is a request to stop making the problem worse — which is a perfectly honest reason, and one we suspect would have landed rather better if it had been said out loud.

Where we come down, for what it is worth, is that the decision was defensible and the execution was not quite. Telling sixty million people to "report signs of fire immediately by calling 999" without a single word about what does and does not count as a sign of fire is how you end up with a jammed control room in Gloucester, and that was foreseeable. And the honest reason — our fire services are at capacity, please do not add to it — was a better argument than the one that was actually made.

But none of that changes what you should do, which brings us to the only genuinely important paragraph in this article.

The most serious objection, and the one we want you to read properly

Everything above is an argument about policy, and reasonable people can disagree about it over a cup of tea. This next part is not that, and we would ask you to read it even if you skim the rest.

Domestic abuse charities have said the alert put survivors at risk, and their reasoning is horribly simple. A great many people living with an abusive partner keep a second phone, hidden, which is how they contact a helpline, a refuge, a solicitor or a family member without it appearing on the handset their abuser checks. An Emergency Alert sounds at full volume for ten seconds whether or not the phone is on silent, and it will sound from wherever that phone is hidden — a drawer, a coat lining, the back of a wardrobe, a neighbour’s house. On some handsets it will sound when the phone is next switched on. There is no version of that which is not dangerous.

Veronica Oakeshott, head of external affairs at Women’s Aid, put it plainly: “Survivors of domestic abuse frequently turn to second phones to help them access lifesaving support or flee from abuse,” adding that it is vital those devices stay hidden. Maggie Evans, director of frontline services at the abuse prevention charity Hourglass, said there had been “no meaningful advance warning to frontline domestic abuse charities” and “no targeted safety guidance for victims”, and that “domestic abuse victims should never be put at risk by the very systems meant to keep us all safe.”

What makes this different from the two national tests is the absence of warning. Before the tests in 2023 and 2025 the date was public for weeks, charities ran campaigns, and anyone with a concealed phone had time to switch the alerts off on it and then switch them back on afterwards. A live alert on a Friday evening offers nobody that chance. The government says it works closely with domestic abuse charities on tests of the system, which rather concedes the point — a real alert is precisely the situation in which that co-operation has not been arranged.

We do not think this makes the alert indefensible, and we can see that a fire service asking for help on the worst day of the summer is not going to be told to wait a fortnight so that a communications plan can be drawn up. But it is the strongest argument on the table by some distance, it deserves a proper answer rather than a line in a statement, and any published criteria for using this system ought to say explicitly how survivors are to be protected when there is no notice to give.

If any of this describes your situation, or the situation of someone you know: the National Domestic Abuse Helpline is 0808 2000 247, it is free, and it is open 24 hours a day. Refuge maintains detailed, device-by-device guidance on Emergency Alerts and on phone safety generally at refugetechsafety.org. If you are in immediate danger, call 999 — and if you cannot speak, dial 999 and then press 55, which tells the operator you need help but cannot talk.

Whatever you think of it, do not switch the alerts off

With one exception, and it is the one above. If you are concealing a phone from somebody who would hurt you if they found it, turn the alerts off on that handset, and do not feel remotely conflicted about it. Your safety is the emergency. Everything that follows is addressed to everyone else.

And to everyone else: we understand the impulse entirely. You were startled, you were mildly patronised about barbecues, and there is a satisfying little act of protest available in three taps of a settings menu. We would ask you not to take it.

Here is the problem. The setting you turn off is not "annoying government messages about barbecues". It is the same setting that carries the gas leak, the chemical incident, the reservoir failure, the flood that arrives at two in the morning, and the words "leave now". Those messages are rare precisely because the threshold is high, and the whole value of the system rests on it being switched on in the eleven months of the year when nothing happens. Turning it off in August because you disagreed with the tone is a decision made by August-you on behalf of a version of you who might badly need it in February, and who will not get a second chance to change it back.

Frankly, if you think Friday's alert was an overreach, the more useful response is to say so — to your MP, in the consultation, in public — while leaving the siren switched on. Those two things are not in conflict.

If you did switch it off, or you are not sure, it lives under Notifications in your phone's settings, usually right at the bottom, listed as Emergency Alerts or Government Alerts. Go and look now, while you are thinking about it, rather than at some later date when you are not.

What to actually do when the next one arrives

The behaviour that makes an alert useful is unglamorous and takes about fifteen seconds.

Stop what you are doing and read the whole thing, including the last line, because the instruction is usually at the end and the panic is usually at the beginning. If you are driving, do not touch the phone at all — it is illegal, and the alert is not going anywhere; pull over somewhere safe and legal, or if there is nowhere, put the radio on, because local radio will be carrying it within minutes. If you are with somebody who is deaf or hard of hearing, or blind or partially sighted, check that they have received it too, and check now rather than then that their accessibility notifications are enabled so the audio and vibration signals reach them.

And then do the thing it asks. That really is it. The alert is a starting pistol, not an essay.

Your to do list is:

Check Emergency Alerts are switched on — for every phone in the house, including the children's and any elderly relative's. Under Notifications, at the bottom of the list.
Have a conversation about it — so that the next siren produces a calm room rather than five people shouting "what's that?" at each other. Ten seconds of noise is much less alarming when everyone knows what it is.
Check the older phones — because a handset more than about seven or eight years old, or one on 2G or 3G only, may not receive alerts at all. If that is Mum's phone, she needs somebody to ring her.
Do not rely on it — and make sure you have a way of finding out what is happening that does not need the mobile network. See our article on keeping informed below.
Sign up to your water and energy supplier's Priority Services Register — if anybody in your household is elderly, disabled, chronically ill or has young children. It is free, it takes about five minutes, and it is a different and far more useful list to be on.
Keep something charged — because every warning system we have now assumes a phone with battery in it, which is an assumption worth quietly undermining.

The kit, and why it is mostly not what you would expect

There is no product that makes an Emergency Alert work better, and we are not going to pretend otherwise. What there is, is kit that covers the two ways the alert can fail you: your phone is flat, or the network is down. Both are entirely ordinary and neither requires the end of the world.

Philips TAR1659 Portable FM/AM Radio at c.£30-£40 – a plain battery radio, and perhaps the single most important thing on this page. When the mobile network goes, and in a large enough incident it will, radio keeps going, and local BBC radio is the designated emergency broadcaster in exactly this situation. It is a slightly comical object to own in 2026 and you will be very glad of it precisely once.

Midland ER10VP Weather Radio with Flashlight at c.£40-£50 – for a little more you get a torch built in and a radio designed for emergencies rather than for kitchens. Whether that is worth it depends entirely on whether you would rather own two things or one, and we can see the argument both ways.

Anker Prime Power Bank 20,000mAh at c.£110-£130 – this is a lot of money for a power bank and we will not pretend it isn't. What it buys you is roughly four full phone charges, which in practical terms is the difference between a household that can still receive alerts on day two and one that cannot. If the price makes you wince, almost any charged power bank beats no power bank, and the important word in that sentence is "charged" — a flat one in a drawer is an ornament.

Blukar LED Torch Rechargeable Ultra High Lumens at c.£20-£30 – included here for the unglamorous reason that people read alerts at night, then go looking for the stopcock, the fuse box or the cat, and the phone torch they are using is the same phone they need to keep alive.

Cabinzero Classic Backpack 36L at c.£70-£90 – if the next alert is the one that says leave, this is the thing you pick up on the way out. Our article ‘Slightly Anxious says Get a Grab Bag’ covers what goes in it, and 19 households in Stourbridge would tell you it is worth an hour of your afternoon.

And the wider point

Being sensibly prepared is not really about kit at all, and it is certainly not about the sort of person who has a bunker and a spreadsheet. It is mostly about not being surprised. The people who coped best on Friday were not the ones with the most equipment, they were the ones who heard the noise, thought "ah, that will be the wildfire thing," and carried on making dinner.

That is all an alert is asking of you: recognise the sound, read the message, do the thing. And keep the thing switched on, so that the one that matters — whenever it comes, and about whatever it turns out to be — finds you paying attention.

If this has been useful, you may also want to read ‘How to keep informed and keep talking’, which covers what to do when the mobile network is the thing that has failed, ‘Slightly Anxious about approaching flames’ for the wildfire specifics, ‘What to do when the lights go out’, and ‘Looking after your pets in an emergency’, because evacuating with animals is the part almost everybody freezes on.
