Within days of the government’s “Be Ready” checklist landing, the shelves actually emptied. Ocado ran out of several types of bottled water, beans and soup. Iceland’s tinned food sales jumped 40%. Maplin’s torch sales nearly quadrupled and radio sales almost doubled in three days — managing director Ollie Marshall said people were reaching for “basics such as torches, wind-up radios, and power banks” within hours of the announcement. Robert Dyas saw the same pattern. Preppers Shop UK reported a 650% jump in “off-grid” sales.

If you’ve been feeling like this all got a bit much a bit quickly, here’s the context that was missing from most of the coverage: it isn’t just Britain, and it isn’t really new. It’s happening in at least 33 countries right now, and in some of them it’s been government policy for the best part of a century.

This is a global story, not a British one

A tracked map of government guidance puts at least 33 countries now actively telling households to keep emergency supplies — not just advising it quietly on a page nobody reads, but campaigning on it. The list spans every inhabited continent: the UK, Ireland, France, Germany, the Netherlands, Denmark, Norway, Sweden, Finland, Estonia, Latvia, Lithuania, Poland, the Czech Republic, Austria, Switzerland and Croatia in Europe; the US, Canada and Mexico in North America; Chile, Colombia, Argentina and Brazil in South America; South Africa; Japan, Taiwan, Israel, India, the Philippines and Singapore in Asia; and New Zealand and Australia.

The specific ask varies by country, and the variation is informative in itself:

• UK, France, Canada, Japan, Mexico, Netherlands: 72 hours of supplies.
• Sweden, Norway: up to a week.
• Germany: up to 10 days — in case emergency aid or critical services are disrupted.
• United States: Ready.gov asks for “several days,” with no fixed number.
• India: a disaster kit, with no stated duration.
• Cape Town, South Africa: at least three days.
• Cyclone-prone Western Australia: a kit with food, water and medication, sized to the local risk rather than a national standard.

The common kit, wherever you are, is the same unglamorous list: non-perishable food, drinking water, medication, batteries, a torch, a radio. None of it is exotic, and none of it requires the “650% increase” panic-buying that made the headlines this week.

Where Britain’s “three days” actually came from

Security Minister Dan Jarvis was explicit about this when the UK guidance launched: the three-day figure was chosen specifically to match “European peers that also use a three-day message.” That’s not a coincidence of wording — it’s the European Commission’s own Preparedness Union Strategy, published back in March 2025 under Crisis Management Commissioner Hadja Lahbib, which asked all EU citizens to hold a minimum 72-hour emergency kit. France’s Normandy region put it on social media in characteristically blunt terms: “Do not wait for the emergency to happen, prepare now.”

Britain isn’t in the EU any more, but it’s adopted the EU’s own number. Make of that what you will — we’d read it as catching up with a continental norm rather than reacting to anything specifically British.

Some countries have been doing this for decades

The bit that rarely makes the panic-buying headlines: several of the countries on that list aren’t reacting to anything. They’re maintaining a habit.

• Sweden has told households to keep roughly 1,000 Swedish krona (about £80) in cash at home in case electronic payment systems go down, alongside its “If Crisis or War Comes” household guidance.
• Switzerland has run national emergency reserves of meat, rice and sugar since the interwar period of the 20th century.
• Finland has run a comparable national reserve and household-preparedness system for more than a hundred years.

None of those three countries had a sellout week. They didn’t need one — the habit was already there before this month’s headlines existed. That’s arguably the most useful fact in this whole story: the goal isn’t a frantic shop on the week the news tells you to, it’s a kit that’s already sitting in the cupboard, quietly rotating, the next time anyone mentions it.

Why now, and why it isn’t really about any one threat

Reporting on this round of guidance keeps citing the same cluster of reasons: extreme weather, hostile state activity, and disruption to power, payments or supply chains — without any single confirmed trigger behind the timing. Wes Streeting, asked about it on BBC Newsnight, deliberately pulled the framing away from geopolitics and back toward the ordinary: having tinned food and a torch in the house helps with disruption “whether that’s flooding, power cuts or burst pipes.” That’s also the honest British framing, and it’s the one we’d stand behind — most people reading this will use their kit for a power cut or a burst pipe long before they use it for anything more dramatic.

What to actually do with this

Nothing about the global picture changes the advice we gave when the Be Ready campaign itself launched — if anything it confirms the UK number is modest by international standards, not alarmist.

• Don’t panic-buy. Three days of ordinary tinned food and water you’ll actually rotate through normal use beats a cupboard of things bought in one go that you’ll eat out of boredom next month.
• Build it like Sweden or Finland would — a standing habit with a six-month check, not a one-off reaction to a news cycle.
• If you haven’t put a grab bag together, our UK 72-hour grab bag guide is built around exactly the figure every one of these countries is now using.
• If a power cut is your realistic scenario — and for most UK households it is — our power cut kit guide covers the torches and radios everyone’s suddenly buying, at the level of detail the headlines skip.
• If you’re short on space, the flat-prepping version covers the same ground without assuming a garage.
• For the official UK checklist itself and what’s genuinely changed in it, see our piece on the Be Ready launch.

Bottom line: the empty shelves this week weren’t a British overreaction to a British warning. They were a British reaction to a genuinely global policy shift that’s been building since the EU’s Preparedness Union Strategy in March 2025 — and several countries got there a century before the EU did. The number being asked of you, three days, is on the low end of what’s being asked elsewhere. Build it steadily, check it twice a year, and you’ll be done long before the next news cycle makes everyone else do it in a panic.
