Government's 3-day emergency kit advice explained: What you really need at home

The government's Be Ready campaign advises British citizens to maintain emergency survival kits at home to prepare for natural disasters or foreign threats. These kits should sustain a household for three days without essential services. Recommended supplies include food, warm clothing, and 36 litres of water for a family of four. Additionally, the guidance suggests stocking cash, emergency radios, and phone chargers to ensure readiness during critical events where standard infrastructure may fail or become unavailable.
