Jot down a few questions to make the most of your conversation.
What a power outage means
A power outage happens when the electricity supply to your home, street, or wider area stops unexpectedly. In the UK, this can be caused by severe weather, faults on the network, accidents, or planned maintenance.
Most outages are temporary and are resolved by the local electricity network operator. However, the impact can range from a few minutes without power to several hours or, in rare cases, longer.
What stops working
When the power goes off, lights, heating systems, and most electrical appliances will stop working. If you rely on an electric boiler, storage heaters, or a heat pump, your home may quickly become cold.
Broadband routers, Wi-Fi, and mobile charging can also be affected. Fridges and freezers will stay cold for a while, but they should be kept closed to preserve food for as long as possible.
How it affects everyday life
A power cut can disrupt work, cooking, and communication. If you are using a laptop or phone, battery life may become limited if the outage lasts longer than expected.
It can also make it harder to move around safely, especially in dark stairways or outdoor areas. For older people, young children, or anyone with medical needs, the disruption can be more serious.
What to do during an outage
First, check whether the problem is only in your home or affects the wider area. If your neighbours also have no power, the issue is likely with the local network rather than your fuse box.
Turn off or unplug sensitive appliances to protect them from any power surge when electricity returns. Keep a torch handy rather than using candles, as candles can create a fire risk.
Who to contact in the UK
If you are in the UK, you should report a power cut to your local electricity network operator. Their phone number is usually available on your electricity bill or on their website, and many have a 24-hour helpline.
If someone is in immediate danger, such as due to a fallen power line, call 999 and stay well clear of the area. You should never touch damaged cables or try to move them yourself.
Preparing for future outages
It helps to keep an emergency kit with a torch, spare batteries, phone power bank, bottled water, and some non-perishable food. A battery-powered or wind-up radio can also provide updates if mobile networks are busy.
If someone in your home depends on powered medical equipment, make sure you have a backup plan. You may also want to keep a list of important contacts and a fully charged phone for emergencies.
