Unplanned power cuts happen when there’s a problem on the power network. Like the trip switch in your home, the electricity network has safety equipment which switches power off if it detects a problem. This can happen if someone or something has damaged a wire, cable or other piece of electrical equipment.
What you can expect
If you have a power cut, you should report it online. Your local network operator will look into the problem and keep you updated while they work to reconnect you.
Depending on the cause of the problem, they might need to send a team of engineers to look at equipment or a substation near your home. They will rarely need to come into your home but if they do, they will always show identification. If someone calls at your door, always check their identification badge. You can call 105 for free to confirm they are who they say they are. Genuine power company employees won’t mind waiting outside while you do this.
If you are a member of the Priority Services Register and it’s likely the power will be off for a while, your network operator will try and contact you to keep you updated.
