What is an MPAN number?

The electricity identifier

Your MPAN is a unique number that specifically identifies your electricity supply point in Great Britain. It is like a postcode for your electricity meter, ensuring that your supply is accurately identified within the UK's regulated energy market infrastructure. This number remains the same regardless of your energy supplier or if your physical meter is replaced.

MPAN vs MPRN vs meter serial number

It is easy to confuse the MPAN with other numbers related to your energy supply, but they serve distinct purposes:

  • MPAN (meter point administration number): This 21-digit number is solely for electricity supply points. It identifies the supply point itself, not the physical meter.
  • MPRN (meter point reference number): This is the equivalent unique reference number for your gas supply point. It identifies your gas supply, similar to how an MPAN identifies your electricity supply.
  • Meter serial number (MSN): This is the unique identifier printed on your physical electricity or gas meter hardware. The MSN changes if your meter is replaced, but your MPAN or MPRN remains constant for the supply point.

What is the difference between an MPAN and an MPRN?

An MPAN (Meter Point Administration Number) is a 21-digit reference number unique to your electricity supply point in Great Britain. An MPRN (Meter Point Reference Number) is a similar unique identifier, but it applies specifically to your gas supply point. Both are essential for managing your energy accounts and switching suppliers.

Understanding the MPAN structure

The 21-digit MPAN is not just a random sequence of numbers; it contains coded information about your electricity supply that helps energy companies and network operators understand the specifics of your supply.

Why you need your MPAN

Your MPAN is more than just a number; it is a vital piece of information for several key aspects of your energy management.

For switching energy suppliers

When you decide to switch energy suppliers, your new provider will ask for your MPAN. This number allows them to accurately identify your electricity supply point and initiate the transfer process seamlessly. Without your MPAN, switching suppliers would be impossible, as they wouldn't know which supply point to take over.

For managing your account and billing

Your MPAN is printed on your electricity bills and is used by your current supplier to manage your account. It ensures that your consumption data is correctly associated with your property and that you are billed accurately for the electricity you use. If you have any queries about your bill or account, quoting your MPAN can help your supplier quickly access your details.

How to find your MPAN

Locating your MPAN is usually straightforward. Here are the most common methods:

On your electricity bill

The easiest place to find your MPAN is on a recent electricity bill. Energy suppliers are required to display this number clearly. Look for a box or section labelled "MPAN", "Supply Number", or "S Number". It is typically a 21-digit number, often presented in a grid format.

Through your online account

Most energy suppliers provide online account management portals. If you have an online account with your current supplier, you can usually find your MPAN by logging in and navigating to your account details, billing information, or supply point section.

Using online lookup tools

If you don't have a bill handy or access to an online account, you can use an online tool. The National Grid's "What's My Supplier? Tool" can help you identify your electricity supplier and, in many cases, your MPAN directly. You'll typically need your postcode to use this service effectively.

Contacting your current supplier

If the above methods don't work, contact your current electricity supplier's customer service. They will be able to provide you with your MPAN after verifying your identity and account details.

What if you cannot find your MPAN?

Sometimes, finding your MPAN can be a bit more challenging, especially if you've recently moved or don't have access to previous bills.

No bill available

If you don't have a recent electricity bill, try checking your online account or using the National Grid's "What's My Supplier? Tool". If these options are unavailable, contacting your current supplier directly is the next best step. They can usually provide the MPAN over the phone or by email after security checks.

Contacting your distribution network operator (DNO)

Your Distribution Network Operator (DNO) is responsible for the electricity cables and power lines in your area. You can find out who your DNO is by entering your postcode into the Energy Networks Association's "Who's my network operator?" tool. Your DNO can assist with power cuts or network issues, but for MPANs, your energy supplier is the primary contact.

Frequently asked questions about MPANs

Does your MPAN change with a smart meter?

No, your MPAN does not change when you have a smart meter installed. The MPAN identifies your electricity supply point, which remains constant. The smart meter is simply a different type of physical meter hardware that measures your usage and communicates readings automatically.

What if you have multiple MPANs?

It is uncommon for a typical residential property to have multiple electricity MPANs, but it can happen in specific circumstances. For example, if you have a separate electricity supply for an outbuilding or an export MPAN for solar panels, you might have more than one. Each distinct electricity supply point will have its own unique MPAN. If you suspect you have multiple MPANs, check your bills carefully or contact your energy supplier for clarification.
