Your Meter Point Administration Number, or MPAN for short, is the unique reference number for your electricity supply.

People also refer to the MPAN as the ‘S number’ or ‘Supply number’ and it is often confused with the meter serial number, but your MPAN serves a very important purpose.

Your MPAN is used to uniquely identify your electricity supply point, meaning that suppliers know which house to provide energy for when switching.

How do I find my MPAN?

You can find your S number on any recent electricity bill, but it’s not always easy to spot.

Your MPAN will look like the image above, with a large S preceding two rows of numbers. Your MPAN is the 13 numbers on the bottom row.

If you don’t have a recent bill to hand, you can call your supplier who will have a record of your MPAN on file.

Finally, you can call the National Grid on 0870 608 1524 who will also be able to tell you what your MPAN is.
