How to find your gas and electricity meter numbers
In order to set up your school on Energy Sparks, we need to be supplied with your school’s meter details. Energy Sparks uses your meter details as a unique reference number in order to identify your school’s energy data on our system. It can be difficult finding your school’s meter details if you do not know where to look so we have created this guide to help you find the information that Energy Sparks needs.
What is an electricity meter number?
Your school’s electricity meter number is known as a Meter Point Administration Number (MPAN.) It is also sometimes known as a ‘supply number’ or ‘S number’. MPANs are 13 digits long and they often start with 22 or 11.
What is a gas meter number?
Your school’s gas meter number is known as a Meter Point Reference Number (MPRN.) It is also sometimes known as an ‘M number.’ MPRNs are made up of numbers only but they are less than 13 digits long.
What is a Meter Serial Number?
A meter serial number (MSN) is different from a meter number (MPAN and MPRN.) A meter serial number is also known as a Meter ID. The meter serial number refers to the meter itself, whereas, your MPAN and MPRNs refer to the supply. Therefore, if your meter is replaced, the meter serial number will change but your MPAN or MPRN will always stay the same.
Electricity meter serial numbers are made up of numbers and letters. Most will begin with the letter ‘F.’ If you have a smart meter, it will start with either 14P or 15P.
Gas meter serial numbers might be made up of all numbers or a combination of numbers and letters. It usually starts with an ‘L’ and ends with an ‘M.’ On a gas smart meter, it starts with G4P.
Energy Sparks uses meter numbers (MPAN and MPRN) as the unique identifier for your school’s energy data.
Where can I find out my school’s meter numbers?
To find your electricity and gas meter numbers (MPAN and MPRN,) please look at a recent invoice.
The electricity meter number is usually listed in a box marked ‘Supply number.’ This will start with an ‘S’ and will be 21 digits long. You only need to share the last 13 digits on the bottom row.

The gas meter number is usually listed under the Meter Point Reference Number heading.

Please note that physical meters usually have the meter serial number on there but not the MPAN or MPRN.
I’m still having trouble finding my school’s meter numbers, what can I do?
If you purchase your energy through your Local Authority or via a procurement organisation, please contact them and ask them to share the meter details with you.
If you purchase directly from your supplier, please contact them to find out your meter details.
Alternatively, if you have a copy of your school’s recent energy bill, you can share this with Energy Sparks by emailing hello@energysparks.uk and we can help you to identify your meter numbers.
