Electricity emergency

To report a power cut or electrical damage please call us on 0800 032 6990, or call the free UK power-cut number on 105

If you have a power cut, first check whether your neighbours have also lost their supply.

If your neighbours DO NOT have power:

  • Call us on the above number or call 105.

If your neighbours DO have power:

  • Check your trip switch. If the trip switch is still on, call the emergency number. If the trip switch is off, switch it back on
  • If it switches back off, one of your appliances may be faulty so unplug all appliances and then reset the trip switch
  • If only part of your supply has failed, and the trip will not reset, there may be a fault with your internal wiring. Please contact a registered electrician
  • Check your electricity meter. Is the dial/display working? If not, call us
