Prepare for supply chain disruption from cyber or climate emergencies, Streeting warns

The “Be Ready” campaign asks households to prepare for emergencies that could interrupt everyday services. The government wants people to be alert without becoming alarmed. Businesses are also urged to understand emerging risks and plan for supply chain disruption.

Households should store non-perishable food, bottled water and first aid supplies. The recommended kit includes a torch, sleeping bags and an FM radio. People should also write down the frequencies of local or national stations that provide news during outages.

The guidance is designed to help people manage for three days while emergency services focus on those needing the most support. The advice follows warnings about wildfires, expected flooding, cyber-attacks and hostile activity. Ministers say stronger preparation could improve the UK's national resilience and reduce dependence on others during crises.

In this context, supply chain disruption means an emergency interrupts the systems that move, sell or support essential goods and services. People could lose access to food, water, energy, communications or sewage services. The disruption may begin digitally, physically or through severe weather.

For example, a cyber-attack on a shop could make card payments fail at the till. A hostile state or terrorist group could target businesses or supply networks. Wildfires and flooding could also interrupt normal operations. The key mechanism is that one damaged part of a connected system can prevent goods or services from reaching users.

The risk matters because modern households depend on reliable networks. The National Audit Office warned that Britain's food supply chain is vulnerable to disease outbreaks, cyber-attacks and extreme weather. The government wants stronger planning so supply chains and energy security continue during a crisis.

The government recommends that households keep enough essential supplies to manage for three days. This preparation is intended for outages or interruptions affecting food, water, communications and other daily needs. It is a basic buffer while emergency services prioritise people who need more help.

The article also reports that 32 government services were temporarily offline while possible cyber-security problems linked to a critical PHP flaw were addressed. PHP is the programming language described as powering much of the internet. Organisations worldwide were scrambling to update systems after the vulnerability was discovered.

The incident illustrates why the campaign includes cyber risks as well as weather emergencies. A digital problem can affect public services even when homes and workplaces appear physically safe. Ministers expect cyber incidents to happen more often, so they want households and businesses to improve readiness before an outage occurs.

An emergency could leave households without basic services they normally rely on every day. The article specifically mentions mains water, sewage, phones and internet access. Power cuts could also affect homes and shops. These interruptions may make ordinary communication, hygiene, shopping and payment difficult.

The campaign therefore recommends keeping non-perishable food, bottled water, first aid supplies, a torch and sleeping bags. If a local shop suffers a cyber-attack and card payments stop working, stored supplies could help people manage. An FM radio could provide updates during outages, especially if people have written down useful station frequencies.

The immediate effect would be inconvenience and reduced access to essentials, while emergency services respond. Security Minister Dan Jarvis said preparation should help emergency services prioritise people who need more support. The wider aim is to make households and the country more resilient to cyber-attacks, severe weather and other crises.

The article identifies several possible causes of disruption. They include hostile state actors, terrorists, organised criminals and severe weather. Plant or human disease outbreaks are also mentioned as threats to the food supply chain. These risks differ, but each can interrupt services or the movement of essential goods.

Hostile states may engage in espionage or sabotage, while terrorists and criminals can target businesses or digital systems. The article highlights increasingly sophisticated cyber-attacks and says artificial intelligence can create threats when people push against conventional cyber defences. Wildfires and flooding provide non-digital examples of emergencies that can damage normal operations.

The government considers all these risks because the UK depends on interconnected services and supply networks. Its national security strategy warned of possible direct threats and a wartime scenario. Ministers want the country to reduce reliance on others and maintain supply chains and energy security during a crisis.

The campaign suggests relying on simple, prepared resources when digital systems fail. For information, households should keep an FM radio and write down the frequencies of national or local stations. This provides a way to receive updates during outages affecting phones or the internet.

For essential goods, people are encouraged to store non-perishable food, bottled water and first aid items at home. Those supplies could help if a local shop suffers a cyber-attack and card payments stop working. A torch and sleeping bags are also recommended for difficult conditions. The article does not give a specific replacement for digital card payments.

These alternatives matter because emergencies can affect several connected services at once. Radio can continue delivering news through an outage, while stored supplies reduce immediate dependence on shops. The government says this preparation should help emergency services focus on people who require more support during a crisis.

A vulnerability in widely used software can create a shared problem for many organisations. PHP is described in the article as the programming language that powers much of the internet. If a critical security flaw is found, every organisation using affected systems may need to act quickly to protect its services.

The key mechanism is common dependence. A weakness in the same programming language can appear across websites, online services and organisational systems. Organisations around the world were scrambling to update their systems after the flaw was discovered. In the UK, 32 government services were offline while potential cyber-security issues were addressed.

This shows why cyber incidents can become broad public-service problems rather than isolated technical failures. Streeting said such incidents will happen more and more. The government wants better preparedness because future attacks or vulnerabilities could interrupt access to services, businesses and supply chains.
