If you’re experiencing a power cut, call 105 free (lines are open 24 hours a day).

Important:

Do not call your electricity supplier to report a power cut. Your distribution network operator (DNO) maintains the power lines that connect your home or business to our network. When you call 105, you will be put through to your DNO.
