Short answer. In the UK, national preparedness advice comes from the Cabinet Office through its GOV.UK/Prepare website 12. It asks households to keep supplies for an emergency lasting a few days, with at least 2.5-3 litres of drinking water per person per day 1. Warnings reach phones through Emergency Alerts 4. No public shelter programme is published; the advice is to shelter indoors or evacuate on instruction 5.
Information verified on 20 October 2026.
Who is responsible for emergency preparedness in the UK?
The Cabinet Office's Resilience Directorate developed GOV.UK/Prepare and is responsible for national resilience policy 2. Local planning is done by Local Resilience Forums (38 in England, 4 in Wales), 3 Regional Resilience Partnerships in Scotland and Emergency Preparedness Groups in Northern Ireland 2. The UK Health Security Agency (UKHSA) gives radiation and health protection advice 56.
The UK has no printed household crisis booklet in current use; GOV.UK/Prepare, with a printable household emergency plan, is the official resource 12. A national resilience public engagement campaign anchored in GOV.UK/Prepare was announced in July 2026 to launch later in the year 3.
