Start with dependencies. Once you know what stops when the electricity stops, you can decide which items need backup, which need a manual workaround and which can simply wait.
Know what an outage changes
List everything that depends on electricity
Walk through the property and write down the systems you normally take for granted: heating controls, borehole or well pumps, sewage treatment, freezers, alarms, cameras, gates, garage doors, routers, telecare, livestock equipment and workshop systems. The point is not to back up everything. It is to spot the few failures that would create a safety or welfare problem quickly.
Note whether each item stops immediately, has a manual release, contains a battery or can safely wait. Government emergency guidance warns that gas ovens and boilers may still fail without electricity, and that internet, mobile service and even mains water can be disrupted.
Write a simple household outage plan
Decide who does what when the power goes off. One person can check the network operator, another can secure gates or animal areas, and somebody can make sure vulnerable household members are comfortable. Keep the plan short enough to use in the dark. A complicated emergency folder nobody reads is less useful than one page of clear priorities.
Include children, older people, visitors, pets and anyone who may not be able to operate equipment alone. Keep the plan short enough to use in the dark.
First actions: Give each adult one clear first job and place a printed copy of the plan beside the emergency kit.
Save reporting and emergency contacts
Store 105 for electricity network problems, supplier details and any essential local contacts on paper as well as in phones. If the cut is widespread, mobile data may be slow and the router will not help you. Write down the property's full address and what3words location too, particularly if emergency services can struggle to find the entrance.
Keep the network operator, energy supplier, medical or equipment provider, insurer, neighbours and animal-care contacts together. Use 999 or 112 only for a life-threatening emergency, fire or immediate danger—not simply to report an outage.
Reporting details: Add the correct outage number and your property details to the paper plan.
Register for priority support if eligible
The Priority Services Register can provide extra support for people who are vulnerable because of age, disability, medical needs or other circumstances. Registration does not guarantee uninterrupted power, so it should sit alongside your own practical plan. Keep the details current if needs change.
Your energy supplier and electricity network operator may keep separate Priority Services Registers, so check both. Registration can improve support but does not guarantee uninterrupted electricity, so keep a personal backup plan.
| Need | first layer | Backup consideration |
|---|---|---|
| Lighting | Battery LED torches and head torches | Spare batteries kept with each torch |
| Information | Charged mobile and paper contacts | Battery or wind-up radio with written frequencies |
| Warmth | Layers, blankets, curtains and one warm room | Property-specific safe heating plan |
| Water and food | Bottled water and food needing no cooking | Private-pump, livestock and infant needs |
| Medical support | Plan agreed with clinical or equipment provider | Approved backup power and emergency contacts |
Build safe, practical backup layers
Prepare safe lighting and information
Put torches where people can find them without crossing a dark staircase or yard. Head torches are useful for animal care and hands-on tasks. Keep spare batteries and a battery or wind-up radio. Avoid making candles the default; open flames create a new risk when people are moving around an unfamiliar dark house.
Add a battery or wind-up radio and write down useful local and national station frequencies. Avoid leaving loose batteries touching metal objects, and replace damaged or leaking cells.
Lighting check: Place a working torch by every occupied sleeping area and one beside the main emergency kit.
Store practical food and water
Keep food that can be eaten cold or heated safely with whatever cooking method you genuinely have. If you rely on a private water pump, store drinking water before you need it. Know how long refrigerated and frozen food remains safe and avoid repeatedly opening doors just to check.
During an outage, keep fridge and freezer doors closed. Food Standards Agency advice says a fridge should stay cold for up to four hours and a full freezer for up to 48 hours—24 hours if half full—but these are estimates. A fridge thermometer gives better information, and current official food-safety guidance should be followed.
Food/water check: Add a fridge thermometer, water and two days of ordinary ready-to-eat food your household will actually use.
Plan warmth, cooking and carbon-monoxide safety
Know what heating still works without mains electricity. Many boilers, pumps and controls stop even when the fuel supply is available. Never bring barbecues, camping stoves, patio heaters or generators into the house, garage or other enclosed space. Carbon monoxide can kill long before a cold room becomes dangerous.
If a generator or fixed backup supply is justified, choose it for clearly defined essential loads and arrange safe installation and changeover with a competent electrician. Never improvise a connection to household wiring. Maintain smoke and carbon-monoxide alarms as required for the fuels and appliances at the property.
CO safety: Remove any plan that depends on an outdoor cooking or generating appliance being used inside or in an enclosed building.
Protect medical, telecare and essential equipment
If somebody depends on powered medical or care equipment, get the backup plan from the clinical team or equipment supplier rather than inventing one during an outage. Know battery duration, charging arrangements, warning alarms and where to go if backup power will not last. Keep those instructions on paper.
If the only emergency-calling method is a landline, ask the provider whether it works without mains power and whether a backup solution is available. Do not buy or connect unapproved power equipment to a medical device.
Prepare phones and communications
Charge phones and reputable power banks before severe weather and keep the correct cables together. Remember that broadband routers and many cordless phones stop immediately without power, and mobile masts can also be affected. Agree a simple family contact plan that does not depend on one app or one network.
Emergency mobile calls may roam to another available network, but coverage is not guaranteed. Agree a nearby contact or neighbour check-in and keep paper telephone numbers with the radio and torches.
Phone backup: Charge and label each power bank, then test that it actually charges the intended phone.
Plan for rural systems, access and animals
Private pumps, troughs, electric fencing, ventilation, milking, gates and feeding systems can turn a household outage into an animal-welfare or access problem. Write down the safe manual method for each essential system and keep release tools and keys where authorised people can find them. Test those procedures before winter.
Set a realistic order of priority: people and medical needs, safe water, animal welfare, property access and only then convenience loads. Ask the installer or manufacturer how equipment should be shut down, backed up and restarted; do not assume every motor or pump suits a small portable supply.
Access/animals: Operate each manual gate or door release once in daylight and confirm that every responsible person can use it.
Is backup power worth considering?
It may be justified where an outage creates a genuine medical, water, heating, animal-welfare or access risk. Start with an essential-load list, not a generator advert. Compare a small approved battery backup, uninterruptible power supply or professionally installed generator arrangement against the actual equipment, starting current, runtime, fuel, ventilation, servicing and safe changeover required.
Stay safe during the cut and recover carefully
Act safely while the power is off
Report the outage and follow the network operator's advice. Stay well clear of damaged lines or electrical equipment and assume fallen cables are live. Turn off appliances that could create a hazard when power returns and protect sensitive equipment where appropriate. Do not start improvising electrical connections because the outage is taking longer than expected.
Keep cold-storage doors shut, conserve phone power, use safe lighting and check vulnerable neighbours if it is safe to do so. Never investigate network equipment or storm damage yourself.
Restore, inspect and replenish
When power returns, do not switch everything on at once. Check for unusual smells, heat, leaks or equipment alarms, then restart important systems in a sensible order. Follow manufacturer procedures for pumps, heating, treatment systems and animal equipment. Afterwards, recharge batteries, replace used supplies and note anything that did not work as planned.
Check food temperatures and current Food Standards Agency advice, reset clocks and security settings, recharge batteries and replace used supplies. Record what failed or ran out so the plan improves after every real outage or practice.
Recovery check: Add a post-outage checklist to the kit and review it within 24 hours of any cut.
A 20-minute outage-readiness check
- Find and test the torches; place spare batteries beside them.
- Save 105 and write it on paper.
- Charge phones and power banks, then test the correct cables.
- Locate the manual releases for gates and garage doors.
- Check water, ready-to-eat food, infant, pet and medicine needs.
- Confirm the plan for medical, telecare, pump and animal-care equipment.
- Ask one neighbour whether you should check on each other during an outage.
Field use: print this page and complete the checklist before the next storm warning or planned interruption.
