Every electricity supply point has an MPAN number which identifies that particular
supply point. MPAN stands for: Meter Point Administration Number.
Some properties, usually businesses can have more than one MPAN number on their premises.
Why is your MPAN number significant for solar installations?
Whenever your house or office has solar panels installed, your Distribution Network
Operator (DNO) only identifies your premises by the MPAN number, rather than the
physical address. Therefore, when your installer applies to your DNO for your solar install,
the DNO will request your MPAN number so they can identify the exact supply point.
Where can you find your MPAN number?
Your MPAN number usually consists of 21 digits and starts with an S, followed by a
series of numbers. You can sometimes find your MPAN number at the location of your meter.
If you have a smart meter, you can also find it using the scroll button. It also usually
appears on your utility bill from your electricity supplier i.e., British Gas.
What do the numbers on your MPAN number mean?
Each set of numbers represents different information. For example:
- Profile Type
- Meter Time-Switch Code
- Line Loss Factor
- Distributor ID
- Unique Identifier
- Check Digit
Is the MPAN number needed for anything else?
Yes, if you are intending to apply for SEG - Smart Export Guarantee, you will
need your MPAN number for the application. Again, this is so your export point can be identified.
