MPRN (Meter Point Reference Number)

What it is

MPRN stands for Meter Point Reference Number. It is the unique number given to each gas supply point in Great Britain. It is made up of digits only, with no letters, and like the MPAN for electricity it belongs to the supply point rather than to the meter or the supplier.

Where you will see it

• On your gas bill, normally under the details of your charges.
• On contract documents and renewal letters.
• Sometimes on a label on or near the meter, but the meter's serial number is a different thing and is not interchangeable.

This is a common mix-up. The serial number identifies the physical device, whereas the MPRN identifies the connection. Our guide to where to find your MPRN shows how to tell them apart.

Why it matters

You need the MPRN to get an accurate quote, to switch supplier, to give a meter reading and to move into or out of premises. Using the wrong number can delay a switch or send a quote for the wrong site. The number also links to the annual quantity held for your site, which feeds into how some charges are worked out.

Example

A pub with a kitchen and a separate holiday flat may have two gas supplies, each with its own MPRN. If you ask for one quote using only the pub's number, the flat stays on its old contract. When requesting quotes for several premises, list every MPRN.

Take the MPRN from a recent bill and keep a note of it with the site address.
