Food-supply disruption preparedness
The planner measures food in household-days instead of pretending every household needs the same menu. A household-day means enough suitable food for everyone in your home for one day.
Turn shops / food supply OFF, set your target duration and enter your current shelf-stable food coverage.
Run this scenarioWhy this page exists
Generic checklists often hide dependencies. Home Resilience Check is designed to make those dependencies visible and keep the underlying assumptions auditable.
Source-led, not fear-led
Planning guidance is based on recognised public authorities. During a real event, current instructions from emergency services, utilities and local government take priority over this planning page.
Measure food that is actually usable
Food resilience is calculated in household-days, person-days and meal occasions. The important distinction is preparation: if the selected cooking method is unavailable, only food marked ready-to-eat or no-cook counts toward the active scenario.
Optional energy planning
If you already use a daily food-energy planning figure, you can enter it and the tool will multiply your own figure across the uncovered person-days. The site deliberately does not prescribe an individual calorie requirement.
Use the result as a stockpile gap
The output tells you how many household-days remain, how many person-days that represents and the approximate number of eating occasions. That is more actionable than simply repeating that a 30-day scenario with three days of food leaves 27 days uncovered.
Food disruption can combine with utility failure
A supply interruption is more difficult when electricity or gas is unavailable at the same time. Refrigeration may be affected, cooking options can disappear and shops that remain open may have limited stock. The scenario switches let those failures be combined instead of assuming the food problem happens in isolation.
Prioritise food that matches your actual cooking capability
If the selected cooking method fails, the plan uses only the ready-to-eat/no-cook household-days entered. That can expose a large gap even when the headline amount of shelf-stable food looks adequate.
Use the gap for purchasing and rotation
The person-day and meal-occasion figures provide a useful scale for building a reserve gradually and rotating it through normal household use. The tool does not prescribe brands, diets or emergency-food products.
