What is an MPAN? A Comprehensive Guide to the Meter Point Administration Number
In the modern energy market, the MPAN plays a central role in how electricity is measured, billed and managed. For households and businesses alike, understanding what is meant by “What is an MPAN” can save time, prevent confusion during a move or a switch, and help you navigate invoices with confidence. This guide explains the Meter Point Administration Number in clear, practical terms, with real-world examples and tips for finding, using and safeguarding your MPAN.
What is an MPAN?
The MPAN, or Meter Point Administration Number, is a unique identifier assigned to each electricity supply point across Great Britain. It is used by energy suppliers, distribution network operators (DNOs) and metering agents to locate and manage the specific meter that serves a particular property. Although often printed on invoices and meters, the MPAN is primarily a data reference rather than a value you would typically read off the display of a smart meter.
Put simply, what is an MPAN is best understood as the “address” of your electricity supply point, not the physical meter itself. It links your property to the correct wiring network, the correct meter, and, crucially, the correct billing arrangements. Knowing your MPAN is especially useful during moves, when switching energy suppliers, or when you need to instruct a new meter operator or network company.
MPAN structure and digits
MPANs have a defined structure that helps the industry quickly identify the right points in the network. In everyday terms, an MPAN is a 13-digit number that is typically shown in two lines on the electricity meter or on your energy bill. While the exact formatting can vary slightly by supplier or meter type, the core purpose remains the same: to uniquely identify your electricity supply point within the national grid.
Top line and bottom line: two-line presentation
When you look at an MPAN on a bill or a meter, you may see it presented as two lines. The top line usually contains a series of digits that identify the core supply point, while the bottom line includes additional digits that specify the exact location and characteristics of the meter within the distribution network. This two-line display makes it easier for both customers and industry staff to confirm the correct MPAN at a glance.
Key components you might encounter
Although the industry uses a standard 13-digit MPAN, the way it is shown can differ. You may come across phrasing such as:
- 13-digit MPAN, shown as two blocks on the meter or the bill
- Core MPAN digits followed by distributor-specific digits
- Reference pairings used by suppliers for switching and metering services
What matters in practice is that the number uniquely identifies the supply point linked to your property and that it is valid within the energy market’s data systems. If you ever need to provide this information to a new supplier or a metering contractor, supplying the MPAN in full and exactly as shown is essential.
What MPAN parts do in practice
- Distributor identification: Some digits indicate the distribution network operator responsible for the local area.
- Meter point identity: The remaining digits identify the specific meter and its connection to the property.
- Audit and billing routing: The MPAN allows the system to route read data and usage to the correct customer for accurate billing.
MPAN vs MPRN: understanding the difference
It is easy to confuse MPAN with related reference numbers, particularly when you encounter different energy points or different energy sources. The most common distinction is between MPAN and MPRN.
MPAN – electricity
The MPAN is the Meter Point Administration Number for electricity. It identifies the electricity supply point and the meter in a given property. When you switch electricity supplier, you’ll typically be asked for your MPAN to ensure the new supplier can access the correct meter data and billing.
MPRN – gas
The MPRN, or Meter Point Reference Number, serves a similar purpose for gas. It identifies a gas supply point and its associated meters and is used when arranging gas supply, meter reading, and billing. While MPAN and MPRN are parallel systems for different fuels, they are not interchangeable. If you are dealing with a gas supplier or a dual-fuel service, you will encounter both numbers, each relevant to its own energy type.
Where to find your MPAN
Locating the MPAN is a common task during a move, a switch, or when checking a bill. There are several reliable places you can look:
- On your energy bill: The MPAN is usually printed on the front page or on an accompanying page titled “Meter Point Administration Number.” It may be grouped as two lines of digits or presented as a single 13-digit block, depending on the bill format.
- On the electricity meter: Many meters display a sticker or a small label next to the display bearing the MPAN. Some digital meters offer a menu option to display the MPAN if you navigate through the settings.
- In your online account: If you have an online account with your energy supplier, you can usually view the MPAN by selecting the property or service point associated with your account.
- From the supplier or distributor: If you are unable to locate it, contact your energy supplier or the local Distribution Network Operator; they can provide the MPAN after confirming your identity and property details.
Tip: When you are moving house or arranging a switch, keep a note of your MPAN in a safe place. You may be asked to quote it to a new supplier or a metering contractor, and having it ready can speed up the process and reduce the chance of errors.
Why the MPAN matters in switching and metering
The MPAN is fundamental to how the energy market allocates metering data to the correct customer, and it plays a key role in several everyday activities:
- Switching suppliers: The MPAN ensures that the right meter data and billing history are connected to the new supplier, preventing misreadings or incorrect charges.
- Meter readings: Accurate MPANs help auditors and meter readers identify the point in the network that belongs to your property, ensuring readings are recorded against the correct account.
- Billing accuracy: The MPAN provides a stable reference for energy use and tariff application, helping to avoid mix-ups in charges, credit, or arrears between properties or tenants.
- Network operations: The distribution network operator uses MPANs to manage demand and plan maintenance safely without affecting the wrong customer.
Common questions about the MPAN
What is the difference between MPAN and meter serial number?
The MPAN is a supply-point reference used by the energy market to identify the point of supply. The meter serial number is a hardware identifier assigned to the measuring device itself. You might see both on bills or in supplier portals, but they refer to different concepts: one is about the supply point in the grid, the other about the physical meter.
Can I use the MPAN if I do not have a recent bill?
Yes. If you do not have a current bill handy, you can obtain your MPAN from the online account with your supplier, from the meter display (if available), or by contacting the supplier or the Distribution Network Operator. When you move or set up a new account, you will be asked for the MPAN to ensure proper setup.
What should I do if I cannot locate my MPAN?
Start with your latest bill or online account. If these do not yield results, contact your supplier or the local network operator. In multi-occupancy buildings, the property manager or landlord should also be able to provide the MPAN per unit or per sub-meter if applicable. Do not rely on guesses; provide the exact 13-digit MPAN to avoid misrouting your energy data.
Practical tips for households and businesses
- Keep your MPAN in a dedicated energy folder or secure digital note. It is frequently requested during changes of tenancy or supplier switching.
- When moving into a new property, locate the MPAN for the new service point and share it with the incoming supplier to streamline setup and avoid delays in supply.
- For landlords managing multiple units, maintain a central record of MPANs linked to each property, ensuring updates when tenants or meters change.
- In a business setting, if you operate multiple metering points, create a simple inventory that lists MPANs alongside property addresses, meter IDs and contact details for your facilities team.
Security and privacy considerations
The MPAN is a non-sensitive piece of information on its own, but it is part of a broader energy data set. Treat it as you would any utility data: avoid sharing it publicly, and be mindful when posting energy documents online or on social media. If you suspect that someone has misused your MPAN, report it to your supplier or the Distribution Network Operator; they can verify and correct any mistaken associations.
Historical context and evolution of the MPAN system
The MPAN framework emerged alongside liberalisation of the energy market in Great Britain, aimed at creating a clear, auditable method for identifying every point of electricity consumption. The system has evolved to accommodate smart metering, easier supplier switching, and more robust data governance. Today, the MPAN remains a fundamental building block of how energy data travels from the property to the supplier and grid operators, ensuring reliable, accurate billing and efficient network management.
