MPAN

Key takeaways

An MPAN identifies your electricity supply point, not the tariff.
It’s used for admin tasks like billing and switching, so having the right MPAN avoids delays.
You’ll usually find it on your bill as a “Supply Number” shown in a grid.

What is an MPAN?

MPAN stands for Meter Point Administration Number.

Distribution network operators describe it as a unique reference used to identify an electricity supply point.
That’s why it’s useful for anything that needs to pinpoint the exact supply connected to your premises (especially if you have more than one meter/site).

How is an MPAN shown on bills?

Businesses commonly see MPAN details shown as a “Supply Number” in a box/grid on the bill.

Some suppliers describe it as a 21-digit number beginning with “S” in that grid format, while network operators often talk about the 13-digit core identifier. The practical takeaway is: use the full supply number exactly as it appears on the bill when you’re asked for it.

Why you might need it

You’re most likely to be asked for your MPAN when you’re:

1. setting up an account at a new premises
2. switching supplier
3. querying meter details or correcting billing/supply records
