Keep meals on the table.

Start with three days of ordinary food your household already eats. For an adult planning reference, the NHS uses around 2,000 kcal per day for an average woman and 2,500 kcal for an average man. That means roughly 6,000–7,500 kcal per adult across 72 hours, although individual needs vary.

Do not try to hit that target with biscuits alone. Build three breakfasts, three lunches, three dinners and a few snacks using shelf-stable carbohydrates, protein, fats, fruit/vegetables and familiar comfort foods. Make sure at least the first 24 hours can be eaten with no cooking at all.

Then extend from three days to a week if you have the space and budget. The best emergency pantry is simply a deeper version of your normal pantry that still works when the fridge, cooker or shops do not.

Use 72 hours as the first Prepared Base target, then build toward seven days. Three days gives you meaningful breathing room through a short power cut, severe weather event, local supply interruption or period when shops and deliveries are disrupted. A week gives you much more resilience without turning your home into a warehouse.

For one adult, use roughly 6,000–7,500 kcal across three days as a planning reference, based on the NHS average daily figures of about 2,000 kcal for women and 2,500 for men. Adjust for age, body size, activity, pregnancy, health conditions and children.

The important part is not just calories. Store food you can actually prepare with your available water and fuel, and include at least one full day of meals that can be eaten cold.

Choose food that is familiar, shelf-stable and efficient in water and fuel. A good three-day adult plan might include three breakfast portions, three lunch portions, three evening meals, six snacks and drinks, totalling roughly 6,000–7,500 kcal depending on the person.

Useful categories include oats or cereal, crackers or wraps, tinned fish/meat, beans, ready-to-eat pulses, soups, nut butter, long-life milk, dried fruit, nuts, tinned fruit/vegetables, shelf-stable ready meals and a few high-energy snacks.

Include food that can be eaten directly from the pack or tin. Dried beans and large bags of rice look economical, but both need water and cooking fuel. Your emergency pantry should work when resources are constrained, not create a second emergency in the kitchen.

Normal supermarket food should be your default. It is cheaper, familiar, easy to replace and can be rotated through normal meals. Specialist long-life or freeze-dried food is useful where you need very long shelf life, compact storage or lightweight meals, but it does not need to make up the whole pantry.

A sensible approach is to build the first three to seven days almost entirely from ordinary shelf-stable food, then use specialist products to fill gaps such as compact meals, grab-bag food or deeper long-term reserve.

If you would not willingly eat a product on a normal Tuesday evening, do not buy a cupboard full of it simply because the label says “25-year shelf life”. Familiar food reduces waste, improves morale and is much easier to rotate.

Keep enough food for at least the first 24 hours that needs no cooking. If you then need to cook, use only equipment that is designed for the location in which you are using it.

Outdoor barbecues, camping stoves and similar fuel-burning cooking equipment must not be used indoors, in a garage, tent, conservatory or other enclosed space. They can cause fire and deadly carbon-monoxide poisoning.

For outdoor cooking, keep the appliance stable, away from combustible materials and follow its fuel and ventilation instructions. Indoors, your options during a power cut depend on the appliances and utilities that remain safely available. A resilient pantry deliberately includes ready-to-eat meals so you are never forced into unsafe cooking simply because everyone is hungry.

Choose foods that cook quickly and use absorption rather than large volumes of boiling water. Keep lids on pans, prepare only what you need and use residual heat where appropriate.

Good low-fuel options include couscous, instant oats, noodles, pre-cooked grains, tinned meals, soups and foods that only need warming. Dried beans and some whole grains can consume a lot of both fuel and water; they are excellent pantry foods only if your plan includes the resources to cook them.

A wide-mouth insulated food flask can also help: bring suitable food to temperature, transfer it to the flask and allow retained heat to continue the cooking process. The principle is simple — in an outage, optimise meals for calories per minute of cooking, not culinary ambition.

Keep fridge and freezer doors closed. The Food Standards Agency says a power cut of less than four hours is unlikely to affect the safety of chilled or frozen food. As a guide, a fridge should stay cold for up to about four hours; a full freezer can keep food frozen for up to about 48 hours, or around 24 hours if it is half full — provided the doors stay closed.

Those are estimates, not guarantees. Room temperature, appliance efficiency and how often the door is opened all matter. A fridge/freezer thermometer removes a lot of guesswork.

If food has become too warm for too long, do not rely on smell or appearance to decide whether it is safe. Follow current Food Standards Agency advice and, when safety is uncertain, discard the food rather than risk food poisoning.

Use “first in, first out”: newest items go to the back, oldest items come to the front and are eaten in normal meals. Do a pantry check every three months rather than waiting for a yearly clear-out.

At each check, look for damaged packaging, rusted or bulging tins, pests and items approaching their date. Move anything you need to use soon into your normal kitchen plan and replace it the next time you shop.

Write the month and year on the front of products if the printed date is difficult to find. Keep a simple minimum stock level for staples — for example, never allow your household to drop below three days of ready-to-eat food. Rotation turns preparedness from a pile of “emergency food” into a living system that is constantly refreshed.
