Your electricity network operator looks after the safety and security of your electricity supply. In the event of an electrical emergency or power outage you can contact your individual operator by using the emergency contact numbers shown below. If you would simply like to enquire about guaranteed standards or a service provided by your electricity network operator, please use the general enquiry numbers. To identify your electricity distributor you’ll need the relevant two digits shown as part of your supply number on your electricity bill. This number is made up of 13 digits and shown in the bottom row of the ‘S grid’. The chart below shows an example of this. Alternatively you can call us at 0330 088 2679 to find out who your electricity distributor is.
