What’s My MPAN – And What Does it Mean?

1. What is your MPAN?

An MPAN (Meter Point Administration Number) is a unique number to the property. It is found on the electricity bill issued issue by the supplier. This is sometimes called a Supply Number but it should not be confused by the customer reference number. It is not displayed on the actual meter.   The full MPAN is 21 digits in length and should be printed on the electricity bill for the supply. 

Suppliers can also obtain the MPAN on the behalf of customers by using the MPAS   Customers wishing to find out their MPAN you can also call their local Distribution Company and they will be able to provide the 13 digit MPAN core over the phone.   In most cases this should be enough information to arrange the transfer of an electricity supply, it is also worthwhile asking that they send the information by post – that way you will also receive the full MPAN.

2. What does the MPAN mean?

a) 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.

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

Your profile class will give suppliers an idea of your consumption patterns and your efficiency at using the energy you consume. This in turn is reflected in the standing charge and unit rates that you will be charged. As a general rule, higher usage needs a higher profile.   So shops, small offices, etc are fine on an 03 / 04 tariff, whereas larger users are better off on higher numbers, 05 to 08, and the higher the number the better (lower unit costs).   If there has been a significant change is usage, with may be worth asking your suppler to review your profile.

b) Meter Time Switch Code (MTC)

The Meter Time Switch Code indicates how many registers (set of meter reads or dials) the electricity meter has and what times they will operate during the day. The Meter Time Switch Code will show if the meter has two registers, one which records day consumption, the other night. Numbers 501 – 799 indicate that there are related meters.

c)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 the 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 supply to the meter.

d) Distributor ID

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

e) Meter Point ID Number

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

f) 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 MPAN.
