The UK’s Be Ready advice asks households that can do so to prepare for three days of disruption. It is practical preparation for interrupted services, not a forecast of when an emergency will happen.

A small emergency kit is intended to help a household manage when ordinary services are interrupted. The UK’s Be Ready campaign, launched in October 2026, recommends preparation for three days, so responders can concentrate on people needing the most help.

Its checklist covers drinking water, food that keeps without refrigeration, light, warmth, a radio, cash and household-specific needs. It encourages people to check what they already own and build supplies gradually. Preparation also includes knowing neighbours and arranging extra support where needed; it is not solely a shopping list.

Three days is a planning starting point. It is neither a prediction that an outage will last exactly that long nor a promise that every service will return on day four. The comparison with American military-base resilience concerns different responsibilities and resources.
