UK Resilience Drive Puts Business Continuity in Focus

27 September 2026

Executive Summary

UK businesses and households are being encouraged to strengthen emergency preparedness as the government expands its focus on national resilience against severe weather, infrastructure failure, cyberattack and hostile-state activity.

Official government preparedness guidance recommends households maintain supplies capable of supporting them through emergencies lasting several days.

Recommended preparations include:

• Bottled water.
• Non-perishable food.
• Essential medication.
• Battery or wind-up torches.
• Battery or wind-up radios.
• Portable power banks.
• Spare batteries.
• First-aid supplies.
• Hygiene products.

Government guidance recommends approximately 2.5–3 litres of drinking water per person per day as a minimum survival requirement, with additional water required for cooking, hygiene, medical equipment, babies and pets.

The guidance is not an announcement that the UK expects an imminent attack.

However, it sits alongside a broader strengthening of national resilience.

Ministers are arranging closed-door security briefings with representatives of critical national infrastructure and defence businesses regarding threats from Russia, including cyberattack, sabotage and disruption.

The government is also developing Defence Readiness legislation intended to improve the preparedness of industry, infrastructure and resources during crisis or war.

For businesses, the important message is not to predict the emergency — it is to understand how long the organisation could continue operating if essential services suddenly became unavailable.

UK Impact

The issue extends far beyond household preparedness.

Businesses depend upon:

• Electricity.
• Water.
• Telecommunications.
• Internet connectivity.
• Fuel.
• Banking.
• Payment systems.
• Transport.
• Cloud infrastructure.
• Suppliers.

Government preparedness guidance explicitly acknowledges that widespread power outages, although unlikely, could potentially last several days.

Loss of electricity can also affect telecommunications, internet connectivity and potentially water supplies.

That creates interconnected rather than isolated failures.

Global Impact

Governments across Europe are increasingly examining national resilience against combinations of:

• Extreme weather.
• Cyberattack.
• Sabotage.
• Infrastructure failure.
• Energy disruption.
• Geopolitical conflict.
• Supply-chain interruption.

The UK’s Strategic Defence Review also identified energy, food, water, telecommunications, medical supplies and transport infrastructure as areas requiring protection during crisis or conflict.

For multinational companies, resilience planning therefore increasingly overlaps with national-security planning.

Our View

Businesses should consider conducting a 72-hour operational resilience test.

Ask what would happen if electricity, telecommunications or water were unavailable for three days.

Companies should ask:

• How long can operations continue without mains electricity?
• Is backup generation available?
• How much fuel is held for generators?
• Can generators operate continuously?
• What happens if fuel cannot be delivered?
• Can staff communicate without normal internet access?
• Are emergency telephone numbers available offline?
• Can customers still contact the business?
• Can payments still be processed?
• Can employees access buildings?
• Can refrigeration continue?
• Can critical IT systems operate?
• Is important information available offline?
• Are alternative suppliers identified?
• How much critical inventory is physically held?
• Could the business operate manually?
• Which suppliers represent single points of failure?
• Are business-continuity plans actually tested?

Companies should also distinguish between backup and genuine resilience.

A backup server connected to the same electricity supply is not independent.

Two telecommunications providers using the same physical infrastructure may not provide genuine redundancy.

A generator without secure fuel supplies provides only temporary resilience.

A secondary supplier dependent upon the same manufacturer does not remove supply risk.

The objective should therefore be to identify shared failure points.

The government’s message to households is essentially simple: maintain enough basic capability to function temporarily without normal services.

Businesses should ask themselves exactly the same question.

Resilience is not predicting which emergency will occur — it is ensuring that several different emergencies do not produce the same business failure.
