Where do I find my MPRN?
Your MPRN is on your gas bill, usually labelled MPRN, Meter Point Reference or M number, and typically has 10 digits. If you can't find it, use the Find My Supplier tool at findmysupplier.energy with your postcode, or ask your supplier.
The MPRN (Meter Point Reference Number) identifies the gas supply at your premises. It's the gas equivalent of the electricity MPAN. See the MPRN glossary entry.
Where it appears
- Bill or statement: look for "MPRN", "Meter Point Reference" or "M number". A comparison site's guide says it has six to ten digits, usually ten.
- Online account or app.
- Contract and renewal letters.
Don't copy the number printed on the gas meter itself. That is normally the meter's serial number, and gas meters rarely show the MPRN.
If you don't have a bill
- Go to the Find My Supplier tool (findmysupplier.energy) and enter your postcode. Ofgem points to it for finding who supplies your gas and your MPRN.
- Or ring the Meter Point Administration Service on the number on Ofgem's page; calls are charged.
- Ask your supplier. They can read it from their records.
If there's gas but no MPRN
Cadent, a major gas network, says that if a supply exists but there's no meter, you request a live/dead check and, if live, an MPRN is created. If a meter is installed but has no MPRN, ask the supplier you want to use to register the supply. Other regions use other network operators, so start with your supplier.
Why it matters
You need it for quotes, switching and checking you are billed for the right meter. A business with two gas meters needs both numbers. Keep a note of each beside its address.
Next steps
Read the full MPAN and MPRN guide, or convert readings with the gas units to kWh converter. If you have just moved in, see telling your supplier.
Several gas meters, several numbers
A building divided into units, or with a separate kitchen supply, can have more than one MPRN. Match each number to the meter and address. Quoting for the wrong meter is a common reason a switch is rejected; see why switches are rejected.
Gas MPRN versus meter serial: a quick test
| Number | Where | Looks like |
|---|---|---|
| MPRN | Bill, account, contract | Usually ten digits |
| Meter serial | On the meter | Often letters and digits; smart gas serials reportedly start G4P |
Why accuracy matters
If you give a wrong MPRN to a broker or supplier, the price may apply to the wrong property, or the switch may fail. A correct number also makes it easier to track down a missing supplier if the bill stops arriving; see finding your supplier.
If you run several sites, keep a simple list of each address, its MPRN, the meter serial and the supplier, and update it whenever a contract changes. When you take gas readings, you may need to convert them to kWh; the converter does this for you.
