A power cut can disrupt your business, but acting fast can minimise downtime. Check if it’s an internal issue or a wider outage, ensure staff safety, protect equipment from surges, and communicate with customers. Backup power and a solid plan can keep operations running smoothly. Here’s what to do step by step.
1. What’s the First Thing You Should Do When the Power Goes Out?
The first thing to do when your business loses power is to stay calm and assess the situation. A sudden power cut can be disruptive, but panicking won’t help. The key is knowing whether the issue is internal or external.
Check your circuit breakers to see if the issue is local to your premises.
Look outside to see if streetlights or other buildings are affected.
Contact your electricity supplier for an update on the outage and estimated restoration time.
Inform your employees and guide them to follow your business continuity plan.
If your area is affected, make sure your emergency lighting is working so that staff and customers aren’t left in the dark. Turn off or unplug sensitive equipment to protect it from power surges when electricity is restored.
2. How Can You Keep Employees and Customers Safe?
Safety should be the top priority when the power goes out. A sudden blackout can create hazards, especially in a workplace with machinery, kitchens, or digital security systems.
Ensure exits are clear and emergency lights are working so that staff and customers can move around safely.
Use torches or battery-powered lights instead of candles to avoid fire risks.
Check security systems and alarms—some may have backup power, but others might fail, leaving your business vulnerable.
If ventilation or heating is affected, consider whether it’s safer to send employees home, especially in extreme weather.
It’s also worth reminding staff to avoid using lifts during a power cut in case they get stuck. If customers are in your premises, communicate clearly—let them know what’s happening and whether they need to leave or stay put.
3. Can Your Business Keep Running Without Power?
A power outage doesn’t always mean everything grinds to a halt. Depending on the nature of your business, you may be able to keep operations going.
If you have a generator, switch to backup power to keep essential systems running.
Use a UPS (uninterruptible power supply) for computers and point-of-sale systems to allow a smooth shutdown or limited use.
Switch to manual processes where possible, such as writing receipts by hand.
Encourage remote work if your employees can continue using laptops and mobile hotspots.
For businesses that rely on refrigeration—like restaurants and shops—it’s important to keep fridge and freezer doors shut to maintain temperature for as long as possible. Perishable stock should be monitored, and you should know your insurance cover for spoiled goods.
4. How Should You Communicate with Customers and Suppliers?
Keeping people informed is essential during a power cut. A lack of communication can cause frustration and harm your business’s reputation.
Use social media and your website to update customers about the situation.
Set up an automatic phone message letting callers know about the power outage.
If you have a battery-powered internet hotspot, continue answering emails and messages.
Notify suppliers if deliveries or services will be delayed due to the outage.
If the outage is likely to last a while, consider alternative ways to serve customers—for example, taking card payments via mobile devices or redirecting calls to another location.
5. What Can You Do to Prevent Future Power Disruptions?
While you can’t stop power cuts from happening, you can reduce their impact on your business. Taking preventive steps can help keep operations running smoothly when the next outage occurs.
Invest in a reliable backup generator to keep essential equipment powered.
Use surge protectors to prevent damage to computers and appliances when the electricity comes back on.
Schedule regular maintenance checks for your electrical system to spot potential issues early.
Consider alternative energy sources, such as solar panels with battery storage.
Develop a business continuity plan so that staff know exactly what to do when the power goes out.
6. How Can You Recover After the Power Comes Back?
Once the power is restored, it’s not just a case of flicking everything back on and carrying on as normal. Some equipment may need to be restarted in a specific order to prevent overloads or data loss.
Turn power back on gradually, prioritising essential systems.
Check for damage to electrical equipment before using it.
Monitor refrigeration temperatures to ensure food and perishable items are still safe.
Reassure customers and employees that the business is back up and running.
It’s also worth taking a moment to review what went well and what could be improved. Did your emergency lighting work? Were customers and suppliers updated quickly enough? If there were issues, use the experience to fine-tune your power outage response plan.
7. What’s the Best Way to Be Prepared for the Next Power Cut?
Power cuts are unpredictable, but businesses that prepare in advance can minimise disruption. Taking simple steps now will make future outages easier to handle.
Create an emergency response plan and make sure all employees are trained on it.
Keep a list of essential contact numbers, including your energy supplier and emergency electrician.
Invest in backup power options, such as generators or battery storage.
Use cloud-based systems so that work can continue remotely if needed.
Regularly test your plan to make sure everything works as expected.
Power cuts don’t have to mean lost business. A little preparation goes a long way—and with the right approach, you can keep your staff safe, your customers informed, and your business running as smoothly as possible.
