What is an MPAN?

26th June 2017

The energy industry is so full of jargon and acronyms that even specialists find it hard to follow and understand sometimes. However, as part of our commitment to making energy simple, Haven Power is explaining some of the most common terms.

We’re starting with one of the most basic acronyms: MPAN or Meter Point Administration Number. Each MPAN identifies a unique electricity supply point, although it can apply to several meters – or to none at all when it’s an unmetered supply (e.g. a street lamp).

You can find your MPAN on your electricity bill, by contacting your electricity supplier, or by using this tool by UK Power Networks.

The industry also uses the term Supply Number or S-Number instead of MPAN (note the “S” that appears before the 6-part, 21-digit MPAN in the image below).

Profile Class (PC)

Used for non-half-hourly meters, the Profile Class indicates the expected level of electricity consumption for the site. Large half-hourly customers have a profile class of 00 and the other Class types are:

Meter Time Switch Code (MTSC)

This 3-digit reference code indicates how many registers (set of meter reads or dials) a meter has, and at what times they operate.

It may show a Single Rate, a Day/Night split, or a Seasonal Time of Day.

Line Loss Factor (LLF)

The Line Loss Factor identifies the expected costs of the Distribution Use of System (DUoS). The distribution company charges the supplier this amount to cover the cost of using the cables and network in a region, as well as for possible losses of energy.

Distributor ID

This identifies the local distribution company that manages and distributes your electricity supply. Great Britain has 12 distribution areas.

Meter Point ID Number

This is a unique identification number within a distribution area, used to recognise the metering point.

Check Digit

The industry uses these final numbers to validate the MPAN.
