MPAS - Meter Point Administration Service

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 (or MPAS) for a specific area of the UK. The MPAS 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. 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.

How does this affect my switch?

Usually, when a customer wants to switch their electricity supplier, they will not need to provide their supply number (or MPAN), as this information will be automatically retrieved from an ECOES database information provider. However, in some cases the information the supplier needs to process the application cannot be retrieved. Fortunately, UK Power can automatically detect whether the information is missing, and in such cases users will be asked to enter their supply number before they can submit their application. Your regional distributor will be able to tell you what your supply number is based on your address. The phone numbers for all the regional distributors in the UK are provided below (lines usually open during normal office hours).

More information

ECOES is funded by electricity suppliers and distributors and was designed to assist suppliers in the customer 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.
