If you experience an unexpected power cut, you should report it by calling 105 or visiting the 105 website. 105 is a power cut helpline covering England, Scotland and Wales, and is free to call.
The UK has several Distribution Network Operators (DNOs) who are responsible for overseeing power supply to different regions. 105 will connect you with your local DNO so you can report the problem.
The operator may ask for details like your postcode and address, when the power went out, and if you noticed unusual signs like flickering or noises before the outage. If the power cut has already been reported, you’ll probably be given an estimated restoration time.
If you’re the first to report the issue, engineers will be dispatched to investigate, and you’ll be updated accordingly.
Following reporting the issue, you may be able to stay up to date with progress via channels like your electricity supplier’s website, energy providers' social media pages, or your DNO’s website.
If you ring to report a power cut that only affects your property whilst your neighbours still have electricity, the process may look different. The operator will likely advise you to check your fuse box and reset any tripped switches or suggest testing for faulty appliances.
If your home is the only one affected, the problem is likely inside your property’s wiring. Since DNOs only manage external power lines, they won’t send an engineer to inspect internal electrical faults. Instead, they will advise you to contact a qualified electrician.
When your power goes out, it's easy to panic and fear the worst. Knowing what to do in a power cut can help you stay safe and protect your property and possessions. Here are some steps to take in a power cut.
Firstly, check if the power cut is widespread or only affects your home. This will decide which steps you need to take next. Here’s how to tell:
If the power cut isn’t limited to your home, report it via 105, as per the steps in the previous section.
If the power cut is isolated to your home, you can still report it. However, the operator will likely advise you to contact an electrician, as the cause is probably related to your home’s internal wiring, not a network outage.
A qualified electrician can test your wiring, find the source of the problem, and restore electricity to your home. When you use our emergency call-out service, a NICEIC-certified electrician could be at your door in as little as 30 minutes to solve the issue.
Electrical surges during power cuts can damage digital devices like phones, TVs, laptops, and tablets. Make sure these are unplugged to keep them safe. Moreover, dangerous appliances like irons, electric heaters, and hair straighteners can pose a hazard if they’re switched on/plugged in when the power comes back on.
Use battery-powered lights and torches to navigate your home and make it feel more comfortable. Avoid using your phone torch, as this can drain the battery, and you might not be able to charge devices for a while. Avoid using candles, too, as these can pose a fire risk.
According to the Food Standards Agency (FSA), food in a fridge will stay safe for about four hours without power, while a full freezer will hold a safe temperature for approximately 48 hours (or 24 hours if half full) if the door remains closed. Add a blanket over the appliance for an extra layer of insulation.
When the power returns, check each item for unusual smells, paying particular attention to more high-risk foods like meat and dairy products.
It’s important to keep electronics like phones, laptops, and tablets charged so you can make calls in case of an emergency and receive updates about the power outage. Refrain from using devices unless you need to, and use battery backup chargers if you have them.
Most central heating systems will stop working in a power cut, so it’s important to keep warm, especially during winter. Wear thick clothes, use blankets, and keep doors shut to trap heat in.
Read our guide on how to keep your home warm in winter for more helpful tips on warming your home, even without central heating.
If your power cut is only affecting your home and isn’t caused by a network outage, you may have an internal electrical fault that needs professional attention. You might be able to fix some issues yourself (see DIY vs. Professional: When to call an electrician), but others require the expertise of a qualified electrician.

While you can’t always prevent power cuts, you can be prepared for them. Take these steps to prepare you for any planned or unplanned outages.
The length of a power cut can vary depending on the cause. Most power cuts are resolved within a few hours, especially if they’re due to routine maintenance or minor faults. However, if the issue is caused by severe weather, equipment failure, or more complex problems, restoring power could take several hours or even a day.
When you report a power cut, your electricity network operator will often provide an estimated restoration time, and updates will usually be available via their helpline, website, or social media pages.
Power cuts can have various causes, including bad weather, equipment failure, planned maintenance, and damage caused by trees, traffic, or construction work.
If the power outage is only in your home, it might be because of a tripped circuit breaker, a faulty appliance, or a wiring problem.
If you experience a power cut, you may be entitled to compensation if it lasts for a certain amount of time. The compensation rules depend on your energy supplier and network operator.
Generally, you’re eligible for compensation if your power is out for over 12 hours. Then, if the power is out for 24 hours, you’ll likely be offered a higher amount. However, if the outage is due to severe weather or a major incident, compensation may vary. To claim compensation, you should contact your electricity supplier.
