Where to find an electric meter serial number
An electricity meter serial number or MSN (Meter Point Administration Number) is a unique number used to identify an electricity meter in your home. This number can typically be found on your electricity bill—usually on the bottom left—and on the meter itself.
If you are unable to locate the serial number on your bill, you can check the physical meter, which is usually located on the front, near a barcode. The Meter Serial Number will either be stamped, engraved, or on a sticker on the face of your meter.
For smart meters, the Meter Serial Number can be found next to the barcode on the front of the meter box. It will usually begin with "14P" or "15P".
If you are still unable to find the serial number, you can contact your energy supplier, and they will be able to provide you with the correct number.
It is important to know your Meter Serial Number in several situations, such as switching energy providers, moving premises, or upgrading your meter. Additionally, ensuring that the Meter Serial Number on your energy bills matches the one on your actual meter can help prevent inaccurate billing.

What does an electric meter serial number look like?
A meter serial number (MSN) is an alphanumeric reference used in Great Britain to identify an electricity meter. While meter serial numbers are meant to be unique, duplicates do exist. The serial number is usually a combination of letters and numbers, sometimes just numbers, that identifies your electricity or gas meter. The first letter indicates the manufacturer, the first two digits indicate the year the meter was calibrated and certified, and the second letter (or pair of letters) indicates the company that purchased the meter. The five- or six-digit sequence is a serial batch number. There may be a space separating the groups of numbers and letters. For example, S06DS123456.
Electricity meters in countries other than Great Britain may not follow this standard. On most electricity meters, the Meter Serial Number will begin with the letter ‘F’. If you have a smart meter installed, your Meter Serial Number should be found next to a barcode on the front of the meter box. On electricity smart meters, the Meter Serial Number will begin with either ‘14P’ or ‘15P’. On newer gas meters, you’ll find the Meter Serial Number located, again, above or below the barcode on the face of the meter. For older gas meters without a barcode, the Meter Serial Number may be printed in red and located on the front. Your gas Meter Serial number will usually be longer than the MSN on your electricity meter. This combination of letters and numbers typically starts with an ‘L’ and ends with ‘M’.
For customers on a smart meter, your gas Meter Serial Number can be found by the barcode on the front of the meter and will start with ‘G4P’. You can also find your Meter Serial Number on your energy bills. Most suppliers will list the Meter Serial Number either at the top or bottom of the bill, usually under the ‘Meter Readings’ section. Sometimes your Meter Serial Number will be referred to on your bill as ‘Meter Number’, ‘Meter ID’ or ‘MSN’. If you can’t locate your Meter Serial Number on your bill, you should be able to find it on the meter itself, either stamped, engraved or on a sticker.

Why you need to know your electric meter serial number
An electricity meter serial number or Meter Point Administration Number (MPAN) is a unique identifier for the meter in your home. This alphanumeric reference is used to identify an electricity meter in Great Britain. While these numbers are intended to be unique, duplicate serial numbers do exist.
The meter serial number can be found on your electricity bill, usually on the bottom left, and on the meter itself, typically on the front near the barcode. Knowing your meter serial number is essential for various reasons, including switching energy providers, moving premises, and upgrading or replacing your meter.
When switching energy providers, your new supplier may use your meter serial number to locate your home or business premises if they cannot find your MPAN or MPRN number. This number helps them identify your specific meter and ensure accurate billing.
If you are moving into a new property, it is crucial to verify that the meter serial number on your energy bills matches the number on the physical meter. Inaccurate bills may result from a mismatch, and you could be charged for more or less energy than you have actually used.
Additionally, if you need to replace or upgrade your meter, noting the new meter serial number is essential. Since this number is specific to each physical meter, replacing the meter will result in a different serial number, impacting your billing and energy management.
By understanding the significance of your electric meter serial number, you can effectively manage your energy affairs, ensure accurate billing, and facilitate necessary changes or transitions related to your energy provider or premises.

What to do if your electric meter serial number doesn't match
If the serial number on your electricity meter doesn't match the one on your bill, it could mean that you are being charged for someone else's usage. This may result in you being charged for more or less energy than you have actually used.
First, you should take a reading of your meter. Take a photo of the meter reading and serial number as evidence. Next, you should contact your energy supplier with your Meter Serial Number as soon as possible. Your supplier will be able to tell you what the correct serial number is. If you are unable to find your MPAN or MPRN number, your new supplier will often use your Meter Serial Number to help locate your home or business premises.
If you are still unable to find the serial number, ask your supplier what it is. The test is free. However, if the test shows that the meter is accurate, your supplier will charge you for removing the meter and installing a replacement. If the screen is blank or showing an error message, there is probably a fault with the meter. Tell your supplier straight away or you could be left with no energy. If your electricity or gas has already stopped, your supplier has to send someone to repair or replace the meter.

How to identify your electric meter
Electric meters have serial numbers, which are used to identify them. These serial numbers are known as Meter Serial Numbers (MSN) or 'meter IDs'. They are alphanumeric references used to identify electricity meters in Great Britain.
Firstly, you need to locate your meter. If you are unable to find your meter inside your property, you may need to look outside. You are likely to find your meter box outside, which is usually white. If you live in a flat, you might find your meter on the ground floor. Each meter should be labelled with the corresponding flat. If not, you can contact your landlord, property agent, or supplier to help you locate it.
Once you have located your meter, you can identify it by its serial number. The Meter Serial Number will be either stamped, engraved, or on a sticker on the face of the meter. On most electricity meters, the Meter Serial Number will begin with the letter 'F'. If you have a smart meter, your Meter Serial Number will be found next to a barcode on the front of the meter box and will begin with either '14P' or '15P'. Your Meter Serial Number can also be found on your electricity bill, usually on the bottom left.
In addition to the serial number, you can identify your meter by reading the dials. An electricity dial meter has five or more dials. They each turn to point to a number between 0 and 9. The dials turn in opposite directions to one another, with some starting with a clockwise dial and others with an anticlockwise dial. When reading an electric meter, you should read and write down the numbers as shown on the dials from right to left. If the pointer is directly on a number, look at the dial to the right. If the pointer is between two numbers, use the smaller of the two numbers. If it is between 9 and 0, write down 9.
It is important to regularly read your meter to help monitor your energy use and ensure accurate billing. You can submit these readings to your supplier through a phone call, their website, or an app.
