INTERACTIVE TOOL // 72-HOUR KIT
72 Hour Survival Kit Builder
Three days sounds short until the taps stop, the shops cannot take payment and the phone battery starts falling. Build a realistic household kit and see what your current setup is missing.
SCENARIO: The power is still down. Mobile service is patchy. Authorities are asking people to stay home while engineers investigate whether automated systems can be trusted. Nobody knows whether the disruption lasts three hours or three days. Your first 72 hours are now a logistics problem.

What this builder is trying to prevent
The purpose of a 72-hour kit is not to recreate your normal life in a cupboard. It is to stop the first few days of disruption becoming a chain of avoidable emergencies. UK preparedness guidance recommends thinking about supplies for an emergency lasting a few days and specifically highlights torches, power banks, radios, non-perishable food, water, medicines and household-specific needs.
The builder therefore scores coverage rather than price. A £300 gadget cannot compensate for having no water, no medication plan and no way to receive information when the router is dead. Conversely, a modest kit assembled from ordinary household items can remove a surprising number of failure points.
Your water and food targets are deliberately simple
The result uses two litres of drinking fluid per person per day as a minimum planning baseline and calculates three meal-equivalent portions per person per day. That is not a personalised nutrition prescription. It is a quick inventory target designed to make shortages visible. Children, pregnancy, breastfeeding, illness, hot weather, physical exertion and some medicines can change fluid or food needs, while pets and formula feeding create separate requirements that must be planned individually.
For water, some emergency planners recommend storing more than the drinking minimum because cooking and washing also consume water. The point of showing the baseline is to stop “we have a few bottles somewhere” being mistaken for a measured reserve. Once you know the number, you can decide whether to store additional water for hygiene and cooking.
What a machine-driven crisis changes
In our fictional worst case, scarcity is only half the problem. Information may be contaminated too. If AI-generated voice calls, fake alerts and manipulated social posts appear during a real infrastructure outage, the household that has a paper contact list, a radio and a verification rule has an advantage over one that owns more gadgets but depends completely on the same compromised information channels.
That is why this builder includes documents, cash, keys and a written household plan. If card payments stop, cloud storage is unavailable or family members are separated when the incident begins, those low-tech items can matter more than another battery pack. The goal is not fear for its own sake. It is to make the fictional scenario concrete enough that the boring gaps become obvious.
How to use the missing-items list
Fix essentials before upgrades. Start with drinking water, ready-to-eat food, essential medicine continuity, safe lighting and a way to receive information. Then deal with the particular people in your household: babies, older relatives, disabilities, pets, prescription needs, spare glasses and mobility equipment. After that, add redundancy such as a second charging method or duplicated paper contacts.
Review the kit every few months. Batteries discharge, food dates change, medications change, children grow and people move. The strongest kit is one the household has actually opened and checked, not one that looked impressive the day it was bought.
