UK cupboard · last look October 2026

What should I stock up on?

Food you already eat, for about three days, plus drinking water and a tin opener that works in the dark. Tinned fish, beans, fruit in juice, crackers, peanut butter, UHT milk, and pasta or rice if you can boil a kettle. That covers a power cut, a missed van, or a thin bay. It is not a year’s store, and it is not a reason to clear the aisle.

People type this when a shelf looks thin, diesel is dear, or the news has been loud for a week. The shopping list is smaller than that feeling. A tin of fish, a bag of pasta, a carton of long-life milk, some water, and a tin opener you can find with the lights off. Eat those things on ordinary Tuesdays. Buy them again when the gap appears. If you would not eat it this month, do not put it at the back of the cupboard “for later”.

GOV.UK Prepare is written for a short gap. It asks for bottled water and food that does not need cooking — ready-to-eat tinned meat, fruit or vegetables — and a tin opener. The water figure on that page comes from the World Health Organisation: about 2.5 to 3 litres of drinking water per person per day. About 10 litres covers drinking, a bit of cooking and a basic wash. A few days of plainer meals will not make a healthy adult seriously ill. The practical job is not to be the person in the queue on the first morning, and not to open a tin you then have to throw away.

Why does a cupboard help if the shops are still open?

Because the delays do not arrive on the same day. Fuel can change a price in 1 to 14 days. A parcel from Asia can be 3 to 6 weeks late if the ship goes around Africa. Bread, cooking oil and chicken often take longer than that. A gap in one aisle is often a late lorry. The cupboard is for the boring bit in between: a power cut, a water fault, snow, a van that does not come, or a week when the bottle of oil is simply dearer than last month.

What you are covering How long it usually lasts What the cupboard is for
Power cut or hob off Hours to a couple of days Food you can eat cold, plus a manual tin opener
Mains water off Hours to a few days Sealed drinking water first
One shop, one bay empty Often the same day The brand you already use, so you can wait
A dear week, shelves still full Days to months Tins you bought earlier, eaten on a normal night

Shelves can look full while the price on the bottle has already moved. Cooking oil is the usual example on this site. The tins you already rotate also take the edge off a dear week, because you paid last month’s price. If the worry is the aisle rather than the cupboard, read why UK supermarket shelves look empty and why shops run out when a sea route is stuck.

What should the cupboard actually contain?

Mostly energy food, then protein, then fruit and vegetables, then drinks and the small things that make a tin edible. A cupboard of biscuits is calories and a headache by day two. A cupboard of fish is awkward in a different way. The shares below are a picture for planning, not a rule.

40%

Energy

Pasta, rice, oats, crackers

25%

Protein

Fish, beans, peanut butter

15%

Fruit and veg

Tomatoes, veg, fruit in juice

20%

Drinks and extras

Water, UHT, oil, salt, tea

Planning share, not a shopping law. Salt and oil weigh little and get used a lot. A plain tin is a meal if you can season it.

What lasts longest in a UK cupboard?

Shelf life is mostly the pack and the cupboard, not the brand. Food Standards Agency rules split the date into two jobs. A use-by date is safety. Do not eat the food after that date, even if it looks fine. A best-before date is quality. After that date the food is usually still safe if you stored it as the label says. It may taste flatter.

Tins, dried pasta, rice, oats and UHT milk carry best-before dates. Fresh meat, fresh fish, takeaway rice and most ready meals carry use-by dates. Those live in this week’s fridge. If the power goes, eat them before you touch the store.

Food Unopened, cool and dry Once opened What actually happens
Dried pasta, rice, oats, lentils 1–3 years, often longer Use as normal Stales slowly. Needs water and heat.
Tinned fish in oil or water About 3–5 years 1–3 days in the fridge, out of the tin Best ready protein. Oil-packed holds flavour longer.
Tinned beans, chickpeas About 2–5 years 2–3 days in the fridge Buy in water, not brine, if salt is a worry.
Tinned tomatoes and veg About 1–3 years 2–3 days in the fridge Tomatoes are more acidic, so quality drops sooner.
Tinned fruit in juice About 1–2 years 2–3 days in the fridge High-acid food. Juice adds fluid.
UHT milk About 6–12 months 3–5 days in the fridge Fine in a cupboard until the seal is broken.
Peanut butter About 6–12 months Weeks if cool Calories and protein. Oil can separate. Stir it.
Crackers, oatcakes About 6–12 months Days once the pack is open Goes soft. Still food.
Honey, sugar, salt Years Years if dry Honey can crystallise. Stand the jar in warm water.
Bottled water Up to about 2 years A few days Cool, dark, away from petrol, paint and bleach.
Cooking oil About 1–2 years unopened A few months Rancid oil smells like crayons or old nuts. Bin it.

Those year counts are planning figures for a cool cupboard, not a promise printed on every tin. Low-acid tins — beans, fish, meat — keep their best quality for roughly two to five years if the tin is sound. Fruit and tomatoes are better inside one to two years. Protein and calories stay. Vitamin C is what fades.

A tin keeps because it was heated and sealed. Oxygen stays out. If the rim is dented, the end is swollen, the outside is deeply rusted, or it hisses when you pierce it, the seal may have failed. Bin it. Do not taste it to check.

A tin above the boiler, next to the oven, or in a loft that hits 40°C in July ages faster than the same tin in a hallway cupboard. Damp rusts the outside. Light fades oils. Cool, dry, dark, and off the floor so a leak does not sit the bottom row in water.

What does the date on the tin actually mean?

Mark on the pack What it means What you do
Use-by Safety Eat, cook or freeze before that date. Do not guess after it.
Best before Quality Check look, smell and pack. A sound tin is often fine later.
Best before end Quality, often a month or year Same rule. Common on tins and dried food.

The date assumes you stored it as the pack says. Rice in a damp shed can go off early. A sound tin in a cool cupboard can be fine after the stamp. Once it is open, tip it into a bowl or a plastic box. An opened tin in the fridge tastes of metal, and the food is no longer sealed. Eat opened fish, beans and fruit within a couple of days. If the fridge is off, finish them the same day or bin them.

How much does a family need?

Count days, then people, then food, then water. NHS figures used for an average adult are about 2,000 kcal a day for a woman and about 2,500 for a man. Use 2,000 as the household average or you will buy food you never rotate. A young child eats less. A teenager can eat like an adult. Someone ill, pregnant, or doing heavy work needs more. Treat the table as a floor.

People 3 days of food 7 days of food Drinking water, 3 days Drinking water, 7 days
1 adult 6,000 kcal 14,000 kcal 9 litres 21 litres
2 adults 12,000 kcal 28,000 kcal 18 litres 42 litres
2 adults, 1 child about 16,000 kcal about 36,000 kcal 27 litres 63 litres
2 adults, 2 children about 20,000 kcal about 46,000 kcal 36 litres 84 litres

Three litres a person a day is drinking water only. Once you add a wash and a bit of cooking, GOV.UK uses about 10 litres. That gets heavy. A family of four for three days at the higher figure is 120 litres. Buy the drinking water first. Pets, baby formula and some medical kit need extra on top. The Prepare page says that in so many words.

Drinking water for 3 days

1 adult · 9 litres

2 adults · 18 litres

2 adults and 2 children · 36 litres

Bars scaled to 36 litres. Children counted at the same 3 litres so the water is not under-bought.

Item 1 adult, 3 days Family of four, 7 days Why it is there
Tinned beans 2 12–16 Protein and bulk. Fine cold.
Tinned fish 1–2 8–10 Protein, and useful fats if it is oily fish.
Tinned tomatoes or veg 1 6–8 Turns a tin into a meal.
Tinned fruit in juice 1–2 8 Fluid, taste, some vitamins.
Pasta or rice 250 g 2 kg Cheap energy if you can boil water.
Oats 200 g 1 kg Breakfast. Can be soaked if you cannot cook.
Crackers or oatcakes 1 pack 4 packs Food with no hob.
Peanut butter 1 small jar 2 jars Dense calories.
UHT milk 1 litre 6–8 litres A drink, plus calcium and protein.
Cooking oil a small bottle 500 ml Calories and flavour.
Bottled water 9 litres 84 litres Easy to forget because it is bulky.
Manual tin opener 1 1 Electric openers die with the power.

A one-adult three-day basket is often under £15 in own-brand. A family of four for seven days is a normal shop plus the water, not a second kitchen. Babies change the list more than adults do. Ready-to-feed formula is the safer store if you cannot boil water or sterilise bottles. Powder needs clean water and a clean bottle. Nappies run out faster than pasta. Pet food matters if the animal lives in the house. A few days of the usual prescription, where the GP and the pharmacy will allow it, matters more than another tin of soup. Insulin and some other medicines need a fridge. Ask the pharmacist. Do not guess from a blog.

What does a day of eating look like?

It is a dull day. It is still food. Breakfast can be oats soaked in UHT milk, or crackers and peanut butter. Lunch can be tinned fish and crackers, with fruit in juice. Dinner can be beans and tinned tomatoes, cold if the hob is off, or with pasta if you can boil water. Tea and a biscuit stop it feeling like a punishment. The biscuit is allowed. It is not the meal.

Meal No power, no hob Hob works, water works
Breakfast Crackers, peanut butter, UHT milk Porridge
Lunch Tinned fish, oatcakes, fruit Same, or fish with rice
Dinner Beans, tomatoes, crackers Pasta, tomatoes, beans
Extra Nuts, a biscuit, tea if you have a flask Tea, a piece of chocolate

Cold soaked oats are edible. They are not nice. If you can see a power cut coming, boil a flask while the kettle still works. Oats and tea are a different job once you have hot water.

What should I buy, and what should I skip?

The usual mistake is food you would not eat on a Tuesday, or food that needs a hob, a microwave and a fridge all at once. Buy the boring version of what you already like.

Buy Buy very little of Why
Tinned fish in water or oil Tinned sausages, hot dogs, corned beef Processed meat is salty and fills the shelf
Beans in water Beans in brine Salt adds up if beans are the meal
Fruit in juice Fruit in syrup Syrup is sugar. Juice is fluid
Pasta, rice, oats Instant noodles as the main store Noodles are salt, and they still need boiling water
Food you already eat Novelty ration packs You will not rotate them
A manual tin opener An electric opener Useless in a power cut
Sealed bottled water Tap water in old lemonade bottles Sealed bottles store more cleanly
Low-salt soup you like A cupboard of ordinary tinned soup A lot of soup is salt and water

Ordinary nutrition advice lands on the same short list: oatcakes and oats, tinned pulses, tinned oily fish, nut butter, fruit in juice, long-life milk. Nuts go rancid sooner than a tin, so buy a bag you will finish this month. Salt, stock cubes and vinegar do not feed you. They stop a cold tin tasting like punishment.

What happens to the fridge in a power cut?

A fridge stays cold for about four hours if the door stays shut. A full freezer stays frozen for up to about 48 hours. A half-full freezer is closer to 24 hours. Food that has thawed and sat warm is a bad guess if someone in the house is pregnant, very young, elderly, or already ill. If you are unsure, bin it.

Appliance Door stays shut What to do
Fridge About 4 hours Eat perishable food first. Do not keep opening it.
Full freezer Up to about 48 hours Leave it closed. Cook thawed food if it still has ice crystals and you can heat it through.
Half-full freezer About 24 hours Same rule. Empty space warms faster.
Cupboard tins Unchanged Backup. Not the first meal.

Fridge first, then bread and fruit, then the tins. A full freezer holds cold longer than an empty one because the frozen food is the ice pack. A chest freezer helps if you already own one. It does not carry a house for a week with no power.

How should I store the water?

You run out of water sooner than you run out of biscuits. Sealed bottles are the simple store. Keep them cool, out of sun, and away from petrol, paint, bleach and weedkiller. Plastic picks up smells. A shelf next to a fuel can is a bad shelf.

Tap water in a clean drinks bottle is fine for a day or two. It is a poor long store. If you fill your own, use a container that has only held drinking water, fill it from the cold tap, and change it. Skip old milk bottles. If the mains is off, do not drink from the heating system or the toilet cistern. If you are told to boil water, boil it. If you cannot, use the sealed bottles.

What should I buy this week?

Space stops most people, not the price. Own-brand beans, pasta and UHT milk are among the cheaper calories in a UK supermarket. Water is cheap and takes the room.

Buy this week Buy when you can Leave it
Tin opener, 9 litres of water, 2 tins of beans, 1 tin of fish Pasta, oats, UHT, fruit, oil, salt A second freezer, ration buckets, a year’s rice

Add one extra of something you already buy. Two tins of beans instead of one. An extra carton of milk. After a month you have three days, and you have not made a special trip for food you dislike.

How do I stop it going to waste?

Write the month on a bit of tape. Eat from the front. Once a month, cook two tins into a normal meal and replace them. If you cannot face that meal, you bought the wrong tin.

Newest at the back, oldest at the front. A labelled box beats a wall of tins you have to unstack to read a date.

What if someone in the house cannot eat the ordinary list?

Coeliac disease means the pasta and the oats have to be the gluten-free ones that house already trusts. Ordinary wheat pasta is not a store for them. Diabetes still needs carbohydrates, in amounts you already know, not a tin of sweets. High blood pressure means you watch the brine and the soup. Allergies mean you read the tin you do not usually buy. The allergy box can change between brands.

Vegetarians can skip the fish and use beans, lentils, peanut butter and UHT, or a long-life plant drink with calcium added. A few days will not open a new vitamin gap. A fortnight of plain rice might. Mix it.

A list you can stick inside the cupboard

Check Done when
Manual tin opener in the same cupboard You can find it in the dark
Drinking water for 3 days 9 litres per person, dated
Ready-to-eat food for 3 days Fish, beans, fruit, crackers, peanut butter
One meal that needs a hob Pasta or rice, plus tomatoes
Baby, pet, prescription extras Only what that house actually uses
Rotation Oldest at the front, two tins eaten each month

Three days for the people who live there is enough to start. Eat it, replace it, and only then add days. The shop is still where most food comes from.

Last look October 2026. Water amounts follow GOV.UK Prepare, which uses the World Health Organisation figure of about 2.5 to 3 litres of drinking water per person per day, and about 10 litres once cooking and basic washing are included. Date rules follow Food Standards Agency use-by and best-before guidance. Calorie figures are the usual NHS adult planning numbers.
