Below you will find a guide to why checking your MPAN is important, what information it can provide you with, and how we help you figure everything out!

WHAT IS YOUR MPAN?

It is a 21-digit reference used to identify individual electricity meters. They were introduced in 1998 to help simplify administration for energy suppliers and make it easier for customers to switch their supplier.

The number is separated into two sections: the core and the top-line data.

The core is the final 13 digits. This is the unique identifier of your meter.
The top-line data explains characteristics of the supply you are provided with.

Thanks to the ease of our MPAN calculator we are able to remove the need for you to have to make sense of these numbers.

However, for your intrigue, below is a breakdown of what your MPAN number means:

Section	Meaning
Profile Class	This gives the supplier an indication of the property’s typical energy consumption. Domestic properties will be either in profile class 01 or 02
Meter Time Switch Code	This refers to how many registers (sets of meter numbers or dials) your electricity meter has. Examples of this are single rate registers, day/night split register or a seasonal time of day register.
Line Loss Factor	These numbers indicate the Distribution Use of System charges that your supplier is expected to pay for using the networks and cables in your area
Distribution ID	These numbers identify the regional distribution company for your electricity supply. This company is responsible for the management of the wires that deliver electricity to your home. This number can be useful to you if you need to figure out who operates the electricity network in your area.
Meter Point ID	This number is unique within the distribution area, it identifies the specific meter.

Answering Your MPAN Questions

What do the digits on an MPAN mean?

The Meter Point Administration Number (MPAN) is a vital identifier used in the electricity supply industry to uniquely distinguish supply points. Each MPAN is made up of a combination of digits, providing valuable information about the supply and its characteristics.

The MPAN consists of two main components: the MPRN number, which stands for Meter Point Reference Number, and the electricity supply number, also known as the electricity MPAN. In some cases, it may also include gas MPRN numbers for properties with both electricity and gas supplies.

The MPAN number is divided into segments that represent different aspects of the supply. It includes a meter number, meter point administration number, and profile class, all of which help energy suppliers manage and bill the supply accurately. The digits within the MPAN correspond to specific details like distributor ID, meter serial number, and electricity supply point, enabling efficient communication between suppliers and distributors.

When switching energy suppliers, knowing your MPAN and MPRN numbers is essential. These numbers are typically found on your energy bill or, if unavailable, by contacting the helpline for assistance. As you move to a new property or change suppliers, the MPAN will remain the same, ensuring continuity and a seamless energy transfer.

Understanding the digits on an MPAN can be beneficial in assessing your energy consumption and making informed decisions to optimize your energy usage. As a customer, having access to this unique number helps you find the best energy deals, manage your energy bills efficiently, and ensures a smooth transition between suppliers.

What’s the difference between an MPAN and an MPRN?

The main difference between an MPAN and an MPRN lies in their respective purposes and the utilities they identify. An MPAN, or Meter Point Administration Number, is a unique identifier used specifically for electricity supply points. On the other hand, an MPRN, or Meter Point Reference Number, serves the same function but is exclusively used for gas supply points.

Both the MPAN and MPRN are crucial for accurate billing, energy management, and communication with energy suppliers. The MPAN is utilized by electricity suppliers to track usage, apply tariffs, and manage billing for individual electricity meters. It consists of various segments, including the supplier’s information, meter details, and profile class.

Similarly, the MPRN is essential for gas suppliers to identify and manage gas supply points effectively. Like the MPAN, the MPRN comprises specific segments, such as the distributor ID, meter serial number, and gas supply point details.

While the MPAN and MPRN share similarities in their structure and function, they are specific to their respective utilities—electricity and gas. Customers need to be aware of the distinction between these two unique numbers to ensure proper handling and management of their energy supplies.

Should I give out my MPAN number?

Your MPAN is an essential identifier for your electricity supply, and it is generally safe to provide it to your energy supplier or relevant authorities when required. Your MPAN, which stands for Meter Point Administration Number, helps ensure accurate billing and effective energy management. It contains vital information such as your supplier details, meter reference, and profile class.
