A meter serial number is a unique string of numbers, or numbers and letters, used to identify a gas or electric meter. Sometimes people refer to it as ‘MSN’ for short. It's different to a supply point number.
Finding your meter serial number
Your meter serial number is usually found on the front of the meter, next to a barcode.
We also put it on your energy statement. It'll be listed as the 'meter number'.
If you have an older meter
Some older meters don't have barcodes, and so the serial number might be:
- embossed on the meter (for electricity meters)
- printed in red (for gas meters)

How this is different to a supply point number
The supply point number (your MPRN or MPAN) is a reference point for the property where the meter is located, not the meter itself. When a meter is replaced, the meter serial number will be different. The supply number always stays the same.
