Your MPAN is your unique 21 digit identifier for the electricity supply to a particular address or particular site at an address. It is needed in order to analyse your electricity usage and change suppliers.
It is divided into two parts: the MPAN Core, (13 digits at the bottom) and the Supplementary Data (8 digits at the top) as depicted in the figure below.
MPAN also known as Supply Number or S Number should not be confused with your customer reference number.
The best place to find your MPAN is on your bill. It is there even if you can't find it. If you need help just send it to us and we will find it for you.
MPAN from existing energy bill: If you have an existing electricity bill you should be able to find your MPAN printed on the main pages.
Two of the most important numbers are the Profile Class (top line) and the Distributor ID (bottom line).
Copy all the numbers from the MPAN keeping the top line separate from the bottom. If you can't find it, send us a copy of your bill and we will do it for you.
