   UK 'Black Sky' plans urge households to stock battery radio and three days of supplies

   The UK government and BBC have detailed emergency preparations for a 'Black Sky event', a prolonged, nationwide power outage that would cut electricity, water, mobile networks and internet for days. Official guidance recommends every household keep at least three days of food, water, medication and a battery-powered or wind-up radio to receive BBC emergency broadcasts on FM and long-wave frequencies. The BBC has confirmed its role as the official emergency broadcaster with hardened studios and reserve power to stay on air. Civil contingency experts say a UK-wide blackout has never occurred but is treated as a low-likelihood, high-impact risk.

   Why it matters

   A 'Black Sky event' describes a catastrophic, extended power loss across Great Britain caused by severe space weather, cyber attack or infrastructure failure. Unlike routine outages, it would disable water pumps, fuel stations, cash machines and digital communications simultaneously. The government's 'Prepare' campaign and National Risk Register treat it as a plausible extreme scenario. The BBC's radio continuity plan is designed to function when all other information channels fail, making a simple battery radio the critical link to official instructions.

   What is confirmed

   • A 'Black Sky event' is the informal term for a widespread, long-duration power outage across Great Britain.
   • The UK government advises households to store at least three days of food, water, essential medication and a battery-powered or wind-up radio.
   • The BBC is designated as the official emergency broadcaster and will transmit on FM and long-wave (198 kHz) during a national blackout.
   • Civil contingency assessments rate a GB-wide blackout as low likelihood but high impact; it has never happened historically.

   Still unconfirmed

   • Some reports claim the official plan includes drinking water mixed with bleach for purification.

   What to watch next

   • Publication of the updated National Risk Register with revised likelihood assessments
   • BBC test broadcasts or public drills on the designated emergency frequencies
   • Government 'Prepare' campaign advertising spend and reach metrics
