Power, water, phone service, payments and transport can fail separately—or at the same time. Choose a few to rehearse and get a short household action list. The cause does not need to be known: this is useful for storms, equipment faults, planned work and other disruptions, not an attack forecast.
Immediate safety comes first. This planning aid is not live outage information or medical advice. If someone is in immediate danger, contact local emergency services. If safety depends on powered medical or assistive equipment or temperature-sensitive medicine, make an individual plan with the relevant care team, supplier and utility—do not rely on a generic runtime estimate.
This is only a scenario assumption, not a prediction of how long anything will last.

This is a prompts-and-checklist tool, not a live outage map, probability model, emergency-services dispatch, medical assessment or engineering calculator. It does not estimate how long a battery, medicine or food will remain safe. Follow your utility, care provider and public-health instructions.
For England, the official Prepare service has guidance on power cuts and disabled people and carers. Advice, numbers and support arrangements vary elsewhere; check your local authority and service providers. If you rely on powered medical or assistive equipment, the UK guidance advises making an individual plan with your care team and equipment supplier in advance.
