An MPAN (Meter Point Administration Number) is a unique number to the property found on the electricity bill issued by your supplier. Sometimes called a Supply Number, it should not be confused by your customer reference number

The full MPAN is 21 digits in length and should be printed in the format below on a recent electricity bill.

If you wish to find out your MPAN you can call your local electricity supplier – whose telephone number you will can see at MPAN Requests.

If you ask for their MPAS department they should be able to either tell you the full 21 digit MPAN or arrange to send it to you.

For a detailed explanation of your MPAN see the following:

Profile Class

Every property has a profile class.

Profile classes are used where half -hourly metering is not installed and provides the electricity supplier with an expectation as to how electricity will be consumed throughout the day.

From a domestic customer viewpoint we are interested in two classes 01 and 02. Other classes that exist are 03, 04, 05, 06, 07, and 08. Where half-hourly metering is installed (large consumers) the profile class in 00.

Detailed below are the profile classes used as guidance to show your likely electricity consumption throughout the 24 hour period. You will notice that summer and winter figures are different:

01 Domestic Unrestricted


02 Domestic Economy 7


03 Non-Domestic Unrestricted



04 Non-Domestic Economy 7


05 Non-Domestic Maximum Demand 0-20% Load Factor



06 Non-Domestic Maximum Demand 20-30% Load Factor


07 Non-Domestic Maximum Demand 30-40% Load Factor


08 Non-Domestic Maximum Demand >40% Load Factor



Meter Time Switch Code (MTC)

The Meter Time Switch Code indicates how many registers (set of meter reads or dials) your electricity meter has and what times they will operate during the day. The Meter Time Switch Code will show if your meter has two registers, one which records day consumption, the other night.

Line Loss Factor (LLF)

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

The Distributor ID 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.

Meter Point ID Number

This is a unique number within the distribution area to identify the actual metering point.

Check Digit

This number is calculated from the Distributor ID and Meter Point ID Number to provide a check digit that other systems can use to validate the both numbers.


MPAN Request

If you are trying to obtain your MPAN to enable you to transfer electricity supplier(s) you can do this in number of ways:

  • MPAN from existing energy bill : If you have an existing electricity bill for your property you should be able to find your MPAN. MPANs are often printed at the bottom of the first page of your bill or on the reverse of the front page.
  • MPAN from a DNO MPAS Service: You can obtain your MPAN from the Distribution Network Operator (DNO) who is responsible for the distribution network for your area.

If you telephone the Distribution company for your area they will be able to provide you with the 13 digit MPAN core over the telephone. In most cases this should be enough information to arrange the transfer of your electricity supply, it is also worthwhile asking that they send the information to you – that way you will also receive the full MPAN.
