Power cuts
If you’re experiencing a power cut, you should call 105. Do not call your electricity supplier. Electricity suppliers sell consumers energy and are not responsible for power lines. Calling 105 is a free service.
Who is my distribution network operator?
When you call 105 you’ll be put through to your distribution network operator. Or you can find out which one is yours by visiting this page.
