What is an MPAN for your electricity supply?
MPAN means Meter Point Administration Number. It identifies an electricity supply point; your bill shows a 13-digit core number on the bottom line of the supply-number box [S1]. An installer may need it when assessing connection changes. Confirm the number matches your premises and distinguish import from export details [S2]. Checked October 2026.
What does MPAN mean?
MPAN stands for Meter Point Administration Number. Use it to identify the relevant electricity supply when discussing your site with a supplier, network or installer. UK Power Networks distinguishes its incoming-supply lookup from export MPAN information [S2].
For your business, the immediate task is matching the correct supply to the proposed chargers, solar panels or battery. Read how much power your site has before treating a supply reference as evidence of available capacity.
Where can you find your MPAN?
Look on the electricity bill. National Grid identifies the MPAN as the 13-digit number on the bottom line of the supply-number display [S1]. Record it exactly, including any leading zeroes. Ask the bill payer to confirm the premises and supply it relates to.
An illustration, not a quote: assume your business has two separately billed supplies, one for a shop and one for a workshop. Prepare a two-row schedule with each building, its supply number and the bill reference. Do not send the workshop’s details for a proposal connected through the shop.
Treat this as an administrative example, not a rule that every building needs a separate supply.
How should you distinguish import and export MPANs?
Import identifies electricity coming into the premises; export details concern electricity sent out. UK Power Networks provides separate information for these records [S2]. Ask the installer and network to confirm the appropriate references for your proposed arrangement.
A distribution network operator (DNO) runs the local electricity distribution network. If you lack a bill or supplier details, its Meter Point Administration Service can help identify the registered supply [S3].
Use the DNO application guide and energy supply contract guide. Ask the installer to verify the physical connection and agreed capacity before finalising the design; a correct identifier does not establish either.

Common questions
Can the network operator help if you cannot find a bill?
Yes. The Meter Point Administration Service can identify the registered supplier and provide the supply number. Use the service for your network area [S3].
Should you expect to find the MPAN on the meter itself?
Start with the electricity bill rather than assuming the equipment label is the supply number. Network guidance identifies the bill’s bottom-line 13-digit number as the MPAN [S1].
Does an MPAN show how much extra power you can use?
No. National Grid requests existing and proposed capacity separately from the MPAN when assessing a load change. Ask for a capacity check as well as supply identification [S1].
