Emergency food for normal people: tins you'd actually eat
Some links on this page earn us a small commission at no cost to you. We choose the kit first and add the link second — here's how we make money.
The official standard is simple: keep non-perishable food that needs no cooking, and a manual tin opener (GOV.UK Prepare, checked 26 Aug 2026). Three days of ordinary supermarket tins for one adult costs around £10 at typical Aug 2026 prices. Buy food you already eat, keep it in one cupboard, and rotate it through normal meals.
What the government actually asks for
The Prepare campaign’s food advice is one line long: “non-perishable food that doesn’t need cooking, such as ready-to-eat tinned meat, fruit or vegetables (and a tin opener)”. No brand names, no special products, no set number of days. The same page says you can “add to your emergency kit when you are able and build it up over time”.
That is the whole standard. Everything below is just a comfortable way of meeting it, and it all comes from the same aisles you already walk down. If you want the full cupboard, not just the food shelf, start with the home emergency kit guide.
The “would you eat it cold on a Tuesday” rule
Before any tin goes in the cupboard, ask one question: would you eat this cold, on an ordinary Tuesday, without complaint? Tinned food is already cooked in the can, so cold is safe. Cold is not always pleasant, though, and a disruption is a bad week to discover you hate cold lentil soup.
Baked beans, tuna, sweetcorn, rice pudding and tinned peaches all pass the Tuesday test for most people. Cold condensed mushroom soup does not. The rule also solves rotation, because food you genuinely like never sits long enough to become a problem.
A three-day menu for one adult
Here is three days of meals from ordinary tins, no cooking required. Warm anything you can if you still have a gas hob; everything here is fine straight from the tin if you don’t.
| Day | Breakfast | Lunch | Evening |
|---|---|---|---|
| 1 | Rice pudding with tinned peaches | Tuna and sweetcorn with crackers | Baked beans with cold new potatoes |
| 2 | Rice pudding with the rest of the fruit | Sardines on crackers | Vegetable soup, warmed if you can, with crackers |
| 3 | Peanut butter and honey on crackers | Baked beans, straight from the tin | Tuna, new potatoes and sweetcorn |
The shopping list, at typical supermarket prices (checked Aug 2026 — check monthly):
| Item | How many | Typical price each |
|---|---|---|
| Baked beans, 400 g | 2 | ≈ 60p |
| Tuna chunks | 2 | ≈ £1 |
| Sardines | 1 | ≈ £1 |
| Tinned fruit (peaches, pears) | 2 | ≈ £1 |
| Rice pudding, 400 g | 2 | ≈ 90p |
| Soup you’d eat lukewarm | 1 | ≈ £1 |
| Sweetcorn | 1 | ≈ 70p |
| New potatoes | 1 | ≈ 70p |
That is about £10 from any supermarket, own brands very much included. Multiply by the number of people in the house, and adjust for what your household actually eats. A vegetarian swaps the fish for chickpeas and more beans; nobody’s three days should contain a single tin they’d dread.
Long-life extras worth adding
A few non-tinned items make the menu feel like food rather than rations. All of these sit happily in a cupboard and carry best before dates months or years away.
- UHT milk, for tea, cereal and rice pudding that needs loosening.
- Crackers, oatcakes or crispbread, as the bread stand-in.
- Peanut butter, dense calories that need nothing doing to them.
- Honey or jam, because morale is part of preparedness.
- Dried fruit and nuts, for eating between meals when the kettle is off.
Add tea bags or instant coffee and a way to enjoy them: a flask filled while the kettle still works covers the first evening of a power cut. Our £100 weekend checklist folds all of this into one shopping trip.
What you can skip
Freeze-dried meal buckets and imported ration packs are heavily advertised and there is nothing dangerous about them. You don’t need them, though. Most need hot water, which is exactly what you may not have; they cost several times the price of the tins above; and because you’d never eat them on a normal Tuesday, they sit untouched until their dates quietly pass.
The Prepare campaign’s standard is met in full by the tins aisle. Spend the difference on a second week of food you like, or on water, which runs out long before food does.
Babies
The Prepare campaign is specific here: include “nappies and baby formula – ready made or ‘ready-to-feed’ formula is best as you may not be able to boil water or sterilise bottles”. Keep a few days’ worth of ready-to-feed cartons and rotate them as the baby grows, along with jars or pouches your baby already accepts.
Pets
The same government list says simply, “Don’t forget food for pets”. Keep a few days of whatever your animal normally eats, sealed and dated like the tins, plus a spare bowl. Pets drink from the stored water too, so allow a little extra.
Rotation: check it when the clocks change
Twice a year, when the clocks change in March and October, open the cupboard for ten minutes. Write the purchase month on new tins with a marker, move anything within six months of its date into the kitchen to be eaten, and replace it on the next shop. Because everything passed the Tuesday test, eating the rotation is no hardship.
Best before and use by: what the dates mean
Government food labelling guidance draws one clear line: “use-by dates relate to the safety of food, whereas best before dates relate to quality”. Eating food after a use-by date could make you ill, so those dates are firm. Best before is different: “after the best before date, the food is usually safe to eat but may not be of the same quality”.
Tins carry best before dates, and for those the guidance says you can use your senses, like looking for visible mould on bread or smelling dairy to see if it has soured. Storage matters either way: food stored badly can go wrong before any printed date. For dented, rusty and bulging tins, see how long tins really last.
What this asks of your body
A three-day cupboard is heavy. One person’s three days of drinking water alone weighs 9 kg, since a litre of water weighs a kilogram, and that’s before a dozen tins go in the basket. If carrying that from the car sounds unpleasant, that’s useful information. The five Ready Body tests tell you where you stand in ten minutes.
Frequently asked questions
How much emergency food should I keep?
The Prepare campaign doesn’t set a number of days; it asks for non-perishable food that needs no cooking, built up over time. Three days per person is a sensible start because it matches the government’s water guidance, and a week suits rural households or anyone who’d struggle to get to shops.
Do I need special emergency food?
No. The official ask is ready-to-eat tinned food and a manual tin opener, all from a normal supermarket. Special products mostly add cost and hot-water requirements. The one upgrade that matters is choosing tins you genuinely like, because those get rotated and eaten instead of expiring.
How long do tins actually last?
Best before dates on tins are about quality, not safety, so a sound tin is usually fine after its date. How long depends on the product, storage and brand. The full answer, including dented and bulging tins, is in how long do tins last.
What about allergies and special diets?
Keep what you actually eat, in tinned or long-life form. Gluten-free crackers, dairy-free UHT drinks and tinned pulses all exist in ordinary supermarkets. The Tuesday rule matters double here: in a disruption you cannot rely on popping out for the one product that suits you, so it should already be in the cupboard.
Can I cook during a power cut?
A gas hob you can light safely still works, and warming a tin takes minutes. Otherwise everything in this guide is safe to eat cold. Never use a camping stove, barbecue, patio heater or generator indoors, in a garage or in a tent; they produce carbon monoxide, which the NHS notes has no taste or smell.
Should I eat the fridge or the cupboard first?
The fridge. In a power cut, fridge food has a short safe window and the freezer follows, so the tins are your last line, not your first. The order and the timings are in keep the fridge cold in a power cut.
What drinks should I keep with the food?
Water first: 2.5 to 3 litres of drinking water per person per day is the WHO minimum quoted by GOV.UK Prepare. Add UHT milk and something for morale, like tea bags with that flask. Avoid relying on anything that needs the kettle, and see water storage for quantities.
