The torch is in the right drawer, but nobody remembers which drawer. The power bank is charged, but its cable fits the old phone. The radio works, but the volume control takes several attempts. These are hypothetical examples, yet they describe the sort of small problem a household can check before an actual outage.

You do not need to turn off the mains to find them. Set aside an hour and work through a few ordinary tasks while treating selected appliances as unavailable. Keep the electricity on. The exercise is a chance to improve an arrangement, not a test of endurance.

Agree what you are practising

Tell everyone what will happen and let people opt out. Choose a calm time, preferably while daylight is available, and stop if the activity becomes uncomfortable or unsafe. Keep phones available for real calls. Never call 999 or 105 simply to rehearse.

Leave medical equipment, care alarms, smoke alarms, heating, refrigeration and other essential systems operating normally. Do not change medicines, meals needed for health, or any care routine. If a person depends on equipment, practise finding the agreed instructions and contact details instead of testing the device by removing its power.

The government's power-cut guidance describes several services that can be affected by an outage. Use it to choose a few relevant questions for your home. There is no benefit in attempting to recreate every possible failure at once.

Find light before discussing specifications

Ask someone who did not pack the supplies to find a torch. Keep normal lighting available, and do not create a dark stairway or obstacle course. Check whether the person can operate the switch and whether the light is useful for reading a contact sheet.

A hypothetical family may discover that the brightest lamp is too heavy for the person expected to carry it, or that the button cycles through several modes before reaching steady light. That points towards a placement or usability problem. It does not automatically mean the household needs a more powerful lamp.

Put the torch back where it will actually live. If the successful test depends on leaving everything arranged on the kitchen table, the storage plan still needs work.

Assemble a meal without the normal appliances

Choose suitable food that can be eaten without cooking, following the labels. Keep the fridge and freezer running and avoid repeatedly opening them for the exercise. Do not try out an outdoor stove indoors or improvise a heater. The aim is to find a practical meal from safe, familiar supplies.

In a hypothetical two-person household, the food choice might be fine but the only tin opener may be awkward for one person to use. Another household may discover that its planned meal needs far more preparation water than expected. Record the actual difficulty before buying a solution.

Consider the clean-up as well. Which utensils did you use? Where are the normal hygiene supplies? You can discuss how a water interruption would change the task without shutting off the water or abandoning handwashing. Our emergency food guide can help revise a menu that looked easier on paper.

Follow the contact plan to its next step

Locate the number for your electricity network and the written household contacts. Check them against the relevant official information while normal services are working. Read the next step aloud: which service would you use, what information would you give and where would you look for updates?

For a digital landline, ask what powers the router and handset. Ofcom's guidance explains the need for backup during a power cut. Do not unplug a telecare connection to experiment. Record the questions for the provider and device supplier.

Try charging the actual phone from its intended power bank, following the manufacturer's instructions. Confirm that charging starts. This check establishes compatibility at that moment; it does not prove how many hours the arrangement will last or whether a mobile network will be available.

If you have a battery radio, find a station you would use and write down its frequency. Check that another person can repeat the task. Reception during a real incident may differ, so avoid treating one successful rehearsal as a guarantee.

Finish with changes you can complete

At the end of the hour, record the few things that caused friction. Be specific: "put a compatible cable beside the battery" is actionable; "improve communications" is not. Identify whether each problem needs a purchase, a different location, clearer instructions or a conversation with a provider.

Restore anything moved and recharge equipment as directed. Then make the easiest useful correction straight away. Ask another household member to repeat the task after the change. If they can now find the light or open the meal, you have evidence that the correction helped.

An hour cannot tell you how the household would manage several cold nights or a changing medical need. Those questions need separate planning. Our power-cut guide covers the wider response. The rehearsal earns its time by making a few immediate actions easier when the lights really do go out.
