Finding Your MPAN and MPRN Numbers

When switching business energy suppliers or checking the details of your bill, you’ll often be asked for your MPAN or MPRN. These numbers identify the supply points for your electricity and gas. Knowing where to find them and what they mean speeds up quotes, avoids delays and ensures your contract is set up correctly.

This guide explains the above and what to do if you can’t locate yours.

What Are MPAN and MPRN Numbers?

What is an MPAN?

Your Meter Point Administration Number (MPAN) is a 21‑digit number that uniquely identifies the electricity supply point for your business premises.

It’s sometimes called a:

• Supply Number

• Electricity Supply Point Number

• S‑Number

This number is used by energy suppliers and network operators to make sure electricity is billed to the correct property.

What is an MPRN?

Your Meter Point Reference Number (MPRN) is the unique number for your business gas supply.

It’s sometimes called a:

• Gas Supply Point Number

• Gas Reference Number

• M‑Number

Unlike an MPAN, your MPRN is usually up to 10 digits long and has no letters.

Where Do I Find My MPAN Number?

The easiest place to find your MPAN is on your latest business electricity bill. Most suppliers display the MPAN in a dedicated ‘Supply Number’ box. The number looks like this:

S 01 801 1234 567 8901 2345 6

Where to look on the bill:

• The top section of the bill

• Near the meter reading or supply details

• In a labelled ‘MPAN’ or ‘Supply Number’ box

Here’s a simplified breakdown of each part:

The 13‑digit core is the most important part. This is what suppliers use to generate your quotes.

Where Do I Find My MPRN Number?

You can find your MPRN on your latest business gas bill. An MPRN has no letters or spaces like this:

1234567890

Typical places to look:

• Near the gas meter readings

• In a ‘Gas Supply Point’ or ‘MPRN’ section

• On the first page, often alongside your account number

Can I Find My MPAN and MPRN Without a Bill?

Yes. Even if you don’t have a copy of an energy bill, there are several ways to find your supply numbers.

1. Use the National Lookup Services

Two official services exist:

2. Check Your Meter

Some modern meters display the supply number on the screen or on a sticker attached by the network operator.

3. Ask Your Landlord or Building Manager

Supplies for multi‑tenant buildings are often managed centrally.

4. Ask Your Current Supplier

They can confirm the numbers over the phone after verifying your details.

Why Do I Need My MPAN and MPRN Numbers?

Businesses usually need these supply numbers when:

• Switching suppliers

• Comparing contract quotes

• Setting up a new business site

• Resolving billing disputes

• Checking if a property is live or has a dormant supply

Having these numbers ready makes the switching process faster and avoids delays caused by mismatched supply points.

Why Doesn’t My MPAN or MPRN Match My Meter?

It’s not uncommon for businesses - especially those in shared buildings - to receive mismatched supply details. Common issues are:

• Two meters were swapped during installation

• An incorrect supply was assigned during a previous switch

• Old meters are never removed from the central database

How to fix these issues:

• Ask your supplier to run a meter exchange or site verification check

• Provide meter serial numbers and recent photos

• Confirm the supply point address with the relevant network operator

Resolving these errors early prevents incorrect billing down the line.

In Summary: How to Quickly Find Your MPAN and MPRN

• MPAN = Electricity supply number (21 digits)

• MPRN = Gas supply number (up to 10 digits)

• Both appear on the first few pages of your energy bill

• You can find them without a bill via network lookup services

• Always check your MPAN and MPRN when switching suppliers
