BEFORE THE CUTMAKE A PLAN.

A storm warning arrives while your lights are still on. You have a few hours, or perhaps only a normal weekend, to decide what would be useful if your electricity stopped working. That is the easiest time to discover missing charging cables, an expired torch battery or a phone number stored in an account you cannot access offline.

This article covers power outage preparation before a cut happens: how to make a short, usable household plan, choose supplies according to actual needs, check equipment and avoid common traps. It is not a call for everyone to prepare for a disaster. If outages are a concern where you live, the steps below let you choose which precautions are worth your time and money.

The British Red Cross's October 2026 emergency-kit guidance recommends tailoring essentials to the household rather than purchasing expensive specialist equipment. Start by looking at what you already own.

What should you do before a power outage?

Think of an outage as the temporary loss of several services at once. Lights and sockets stop working; some boilers and water pumps need electrical controls; Wi-Fi routers stop unless backed up; a phone battery is finite; a refrigerator cannot maintain its normal temperature indefinitely. The useful preparation is to identify the consequences that matter most at your address.

Use this table to identify weak points, not to justify buying a product in every category. Some homes have adequate natural light and no critical equipment. Others have a lift-dependent resident or powered medical device and need a much more specific plan.

Find your electricity network operator and keep the contact

The company billing you for electricity is not necessarily the company managing the local cables. In Great Britain, you can use the UK power-cut guidance or call 105 to identify or contact the local network operator; Northern Ireland has its own reporting arrangements. Save the relevant contact and, if useful, write it on paper.

See whether your operator provides a fault map or text alerts and identify how it communicates during storms. The Met Office's power-cut guidance explains the distinction between the distribution network operator and the electricity retailer. Having the correct number prevents a frustrating search when broadband is down.

Check whether your building has a separate management contact for communal supply, lifts or fire systems. If you rent, find out whom to contact about a consumer-unit problem or damaged wiring. Do not attempt electrical work beyond safely accessible controls you understand.

Prepare lighting that does not introduce a fire hazard

Place a reliable battery torch near each essential access route, especially a stairway or bedroom. Check that batteries have not leaked and that you know where replacements are stored. A lantern can illuminate a shared room without leaving somebody holding a phone light all evening.

Battery lighting is usually a safer option than candles, particularly near curtains, children, pets and clutter. If you use rechargeable torches, charge them periodically. For older devices with replaceable batteries, store the batteries according to the manufacturer's instructions and check them at sensible intervals.

Make a short test in a safe, well-lit period: can everyone find their torch without opening a cupboard full of obstacles? Can someone reach the exit and use the stairs without relying on an electric stair light? Solve those issues before buying a more powerful lantern.

Work out which devices deserve backup power

A power bank is useful when you know which devices it can actually charge. Confirm connector compatibility and charging performance with a normal test. Label cables or keep them with the unit. Do not assume a large advertised battery capacity means it can run any appliance: devices have different power requirements, and some batteries cannot power mains-voltage equipment at all.

Choose a hierarchy. Communication and essential care devices usually matter before entertainment equipment. If you work from home, decide whether temporary internet access or a document copy is essential for the next working day. If a medical device depends on power, do not design a homemade clinical backup using a generic power bank; discuss tested equipment, alarms, safe runtime and escalation with the medical supplier or care team.

The Energy Networks Association's 1 November 2026 winter advice stresses keeping essential phones charged and checking whether additional support is available. It does not suggest that purchasing a generator is necessary for every household.

Choose practical food and water rather than a complicated 'survival menu'

Consider a few familiar ready-to-eat or easily prepared foods that you would use anyway: tinned food that can be eaten cold where the label permits, crackers, nut butter where allergies allow, and long-life drinks. Include a manual tin opener if you need one. This need not be a separate store of food that expires forgotten in a cupboard.

For water, think about the number of people, any pets, medical needs and whether the property uses pumps. Clean, sealed food-safe containers may be useful; follow storage instructions and rotate as needed. The British Red Cross provides a broad household emergency-kit starting point, while the correct quantity for you depends on local conditions and requirements.

Before an outage, place a thermometer inside your refrigerator. The Food Standards Agency recommends monitoring the actual temperature after a cut because estimates such as four hours for a fridge and up to 48 hours for a full freezer are affected by ambient temperature and how often doors are opened.

Know whether your heating and hot water need electricity

Even a gas-powered boiler commonly uses electricity for its pump, controls and ignition. Before a power cut, check the manufacturer's instructions or ask the service engineer what happens when the supply fails. Some homes have independently powered heating options, while others have none.

Prepare ordinary warm clothing, layered bedding and curtains that close properly. Do not block vents needed by fuel-burning appliances. Avoid treating a camping stove, barbecue, car engine or portable generator as an indoor heating solution. The NHS warns that these can produce lethal carbon monoxide in enclosed or partly enclosed spaces.

In cold weather, a simple named destination—such as a nearby friend or appropriate community facility—may be more useful than a risky improvised heater. Our winter outage decision guide explains when a colder house should prompt a serious reassessment.

Give medical and accessibility needs their own plan

Some households use powered oxygen equipment, ventilation support, refrigeration for medicines, electrically controlled mobility equipment or telecare devices. The right response cannot be reduced to a generic shopping checklist. Speak to clinicians, equipment providers and, where relevant, building managers about exactly what happens when electricity fails.

The Energy Networks Association's Priority Services Register guidance explains that eligible households may receive extra information and support, but registration does not make a home immune to outages or guarantee uninterrupted supply. Sign up and confirm details where eligible; plan independently for equipment that must remain powered.

Check whether anyone would be unable to operate a heavy door or stairway without an electric mechanism. Identify the manufacturer's safe manual process, not an improvised workaround. Put essential contact details somewhere reachable without relying on one phone.

Make a two-person or household communication plan

A plan can be short enough to fit on one page. Write where the lighting is stored, how to check the network fault map, whom to contact about a medically vulnerable resident and when you will next check on relatives. Decide whether to communicate by phone call, text, radio information or an in-person check where safe.

Do not assume every messaging app is independent. Most depend on a phone, charger and working data connection. If you use a digital landline, ask the provider how its service performs without mains electricity; a powered router or adapter may be necessary. The Met Office highlights this dependency for people without a good mobile signal.

Check insurance, appliances and home access in advance

Learn where the consumer unit is and which devices might restart dangerously after a cut. Never touch damaged or wet electrical equipment. A freezer full of expensive food, a home-based business or a lift-dependent resident can make the financial or practical impact of an outage different from one household to another.

If you are considering a backup generator, ask a qualified professional about correct installation and safe use. Never connect a generator to household wiring through an ordinary socket, which can backfeed the network and endanger workers. Portable generators must never be operated indoors, in attached garages or near openings where exhaust can enter living areas. Do not treat 'a cracked window' as protection from carbon monoxide.

Home insurance may cover some losses from power failure, but terms and exclusions vary; check the actual policy rather than relying on an article to promise reimbursement.

A practical 45-minute preparation drill

1. First ten minutes: identify network operator, emergency numbers and any building manager contact.
2. Next ten: locate torches, batteries, power bank and charging leads; test that they work.
3. Next ten: review food, water, refrigerator thermometer and heating dependencies.
4. Next ten: check medicines, essential equipment, important phone numbers and alternate communication routes.
5. Final five: write down one problem to fix this week and where the household plan will be kept.

Do not conduct this drill by switching off medical equipment, tampering with electrical systems or putting anybody at risk. You can learn most of what matters through a safe inventory and ordinary tests.

What not to buy before answering a simpler question

Expensive 'whole-home survival' packages often bundle equipment with no clear relevance to your property. Before buying a power station, ask what appliance you need it to run, its actual wattage, how long it must operate and whether the device can support that load safely. Before buying large quantities of food, ask where it will be stored and how it will be rotated.

Sometimes the better investment is a working torch and clear contact sheet. A short rehearsal that identifies missing cables may save more frustration than an additional gadget. When you finish preparing, a genuine outcome is being able to find what you need in the dark—not feeling anxious because the list could always be longer.

If an outage actually happens

Switch from preparation to immediate safety. Confirm whether the fault is local or widespread, report it through the genuine network operator, protect vulnerable people, use safe lighting and turn off appliances that could be hazardous if electricity returns. Then reassess as time passes. Our first-hour blackout sequence gives a minute-by-minute framework, while the prolonged-outage guide addresses ongoing household decisions.

Frequently asked questions

What is the first thing I should prepare for a power cut?

Identify a reliable torch and check your household's particular high-priority dependencies—such as powered medical equipment, communication and heating. Know who operates the local electricity network.

Do I need a generator?

Not necessarily. Many households benefit more from safe lighting, charging, essential information and an alternative warm location. Generators introduce cost, electrical hazards and carbon monoxide risk and require professional advice where appropriate.

Can I rely on the Priority Services Register?

It can offer additional communication and support for eligible people, but does not guarantee supply during an outage. Critical medical equipment requires an individual contingency plan with the provider.

What should I do if I have only a small budget?

Start with the highest-impact needs and use items you already own. A torch, printed contacts and an equipment-specific care plan may be more valuable than buying an expensive kit.
