What is an MPRN and where do I find it?
Gas's answer to the MPAN: the MPRN (Meter Point Reference Number), a 6 to 10 digit number that uniquely identifies your gas supply point. It's sometimes just called an "M number".
Where to find it
On your gas bill — usually near the supply address or in the supply details section. Like the MPAN, it is not printed on the meter; the number on the meter is its serial number, which is a different thing. No bill to hand? The national Find My Supplier service can look it up from your postcode — or give us the postcode and we'll do it as part of your quote.
MPRN vs meter serial number
| Number | Identifies | Found on |
|---|---|---|
| MPRN | The supply point (the connection to the gas network) | Your bill |
| Meter serial | The physical meter box, which can be swapped | The meter itself |
Why quotes need it
The MPRN tells a supplier exactly which supply they're pricing and registering — region, network, and consumption history via industry data. Quotes without it are estimates; switches without it can't happen at all. A new supplier registers your MPRN, not your business name, which is why one wrong digit can (briefly) switch the wrong building — it gets caught, but it costs weeks.
The short version: 6–10 digits, on the bill, not the meter. Send it with your annual kWh and your gas quote comes back same-day. Get a gas quote →
