Electricity Supply Number

The Electricity Supply Number is also known as the Metering Point Administration Number (MPAN) number.

Your MPAN is the unique identifying number of the Electricity meter at your property. It is often referred to as a "Supply Number" or "S" number, and it can be found on your electricity bill (generally on the back of the bill).

If you can't locate your number, you should contact your current electricity supplier.

The Line Loss Factor code stipulates the expected costs the distribution company will charge the supplier for using the cables and network in your region. This Line Loss Factor code will also indicate to the electricity supplier the potential charges incurred, due to loss of energy incurred whilst getting the electricity supplier to your meter.

Distributor ID Code

The Distributor ID Code will identify the local Distribution Company for your electricity supply. The Distribution company is responsible for management of the distribution system and electricity wires which transports the electricity to your meter.
