What does MPAS do?

Each regional electricity distributor in the UK (also known as the Distribution Network Operator, or DNO) operates the Meter Point Administration Service (MPAS) for a specific area of the UK.

The MPAS number database, known as the Electricity Central Online Enquiry Service (or ECOES; previously known as MPAS Online), contains information about the supply of electricity to each address in the UK - it's essentially a national database of electricity supply.

You can find out more about ECOES access at or try the ECOES contact number - 0207 090 1024.

One important piece of information found on the database is the supply number or Meter Point Administration Number (MPAN).

The MPAN is a 21 digit number used to uniquely identify your electricity supply. This number is needed by electricity suppliers when you want to switch your supply, so that they can correctly identify your property.

What does an MPAN look like?


Here's what each of the digits in the above meter point administration number on your electricity meter relate to:

  • 01 - Profile class of the meter you have, for example, credit meter or prepaid meter.
  • 123 - Meter time switch code. If you have an Economy 7 or Economy 10 meter, this will show two rates.
  • 456 - Line loss factor. This is used to identify the related Distribution Use of System (DUoS) charges for the MPAN.
  • 16 - Distribution ID relating to the part of the conutry in which you live.
  • 6789 0123 - Meter Point ID number, which is your meter's unique identification numeber.
  • 222 - Check digit. This validates the previous 12 (the core) using a modulus 11 test. The check digit is calculated by multiplying the first digit by 3.

What does an MPRN look like?

Your gas meter wil have a meter point reference number (MPRN), which is a unique numebr assigned to your connection and meter. Your MPRN will contain up to ten digits with no letters, like the example below:

Meter Point Reference 0123456789

How does the MPAN affect your switch?

When switching electricity supplier, you don’t normally need to provide your supply number (or MPAN), as this information will be automatically retrieved from an ECOES database information provider, which is a national database of electricity meters. But, in some cases, the information the supplier needs to process the application can’t be retrieved.

Online gas and electric comparison sites can automatically detect whether the information is missing and, if so, you’ll be asked to enter your supply number before you can submit your application to switch supplier. Your regional distributor will be able to tell you what your supply number is based on your address.

More information on MPAS electricity national database

Funded by electricity suppliers and distributors, ECOES was designed to assist suppliers in the transfer process when customers choose to switch. ECOES is governed by the Metering Point Administration Service Company (MPASCo), who administers a multi-party agreement between all licensed electricity distribution businesses and suppliers in the UK.

The multi-party agreement is called the Master Registration Agreement (or MRA) and sets out terms for the provision of Metering Point Administration Services (MPAS Registrations) and procedures in relation to the Change of Supplier to any premise or metering point.
