How to Prepare for a Power Cut or Flood in the UK
By Clarity Books editorial team · 4 min read · Updated:
Preparing for a UK power cut or flood means keeping torches, warm layers, a battery radio, and a charged power bank ready, knowing your flood risk on GOV.UK, and saving the right helplines such as 105 and Floodline. These are the disruptions UK homes face most, so plan for them before the wetter, stormier months.
The Most Likely UK Disruptions
For most British households, the realistic emergencies are a power cut and a flood, not the dramatic disasters that dominate the news abroad. Winter storms bring down lines and leave homes without electricity for hours or, in rural areas, far longer. Heavy rain and high tides flood properties near rivers, the coast, and places where drains struggle to cope, sometimes with little warning.
Because these are the likeliest events, prepare for them specifically rather than generically. Check your flood risk on the GOV.UK service and sign up for flood warnings if you are in an at-risk area. Note that 105 connects you to your electricity network during a power cut, and join your supplier Priority Services Register if anyone at home relies on powered medical equipment.
Before, During, and After
Before, keep a power-cut kit within easy reach: torches, spare batteries, a wind-up or battery radio, warm layers and blankets, a charged power bank, and some food that needs no cooking. For flood risk, store valuables and documents upstairs or high up, know how to turn off gas, electricity, and water, and keep sandbags or flood barriers ready if your area floods often.
During a power cut, switch off appliances that were on to avoid a surge when power returns, keep the fridge and freezer closed, and call 105 to report it and get updates. During a flood, move to higher ground, avoid walking or driving through flood water, and follow any evacuation advice. After either event, check on vulnerable neighbours, photograph any damage for insurance, and only use the water once authorities confirm it is safe.
Follow UK Protocols in the Guide
Power cuts and floods call for different responses, and remembering the right steps under stress is hard without a plan. Ready For Anything, United Kingdom Edition sets out clear UK protocols for both, from safely managing a long outage to flood preparation and the helplines to call, so your household is not guessing when the lights go out or the water rises.
The guide turns scattered advice into one ordered routine you can rehearse in calm and trust in the moment. If you also spend time on the continent, the Complete Ready For Anything Collection bundles every edition for less than buying them separately. Start with the UK edition to prepare for your most likely disruptions, with the correct numbers and risks built in. These power-cut and flood steps are the start, and our Ready For Anything series builds them into a full UK plan.

Helplines and Alerts
Knowing who to call saves time when something goes wrong. For a life-threatening emergency call 999, or 112 which also works across the UK and Europe. For a power cut call 105 to reach your local electricity network operator for free. Floodline gives recorded and live flooding information, and your water and gas suppliers have their own emergency lines worth saving in your phone.
Set up the alerts that warn you early. Register for GOV.UK flood warnings if you are at risk, keep your phone able to receive the national Emergency Alerts that the UK now tests, and follow your local council and energy supplier for outage updates. With the 2026 emergency-alert rollout and winter grid pressure, having these numbers and alerts ready before you need them keeps a disruption from becoming a crisis.
