What is an MPAN?

Your MPAN or supply number is the unique 21 digit number and is made up of information regarding your meter type and supply point. It is often called an MPAN (meter point administration number) or simply known as the 'S number'.

Where can I find my MPAN?

Your supply number is located on your bill and usually follows a format similar to that depicted. If you can not find this number it may be possible to obtain a quote based on your postcode but this wont be as accurate. If you are still unsure we can always find this information on your behalf, get in touch to find out how.


If you have just occupied a property the easiest and quickest way is to find a statement from the previous occupier's energy supplier. You are what is known as a CoT customer, to understand a bit more check out our guide here, in short as the new occupier, you have inherited the current energy supplier. If you're still unsure, grab the serial number from your meter or take photo of it and get in touch, we will do the rest!

What makes up my MPAN?

Profile Class


Your profile class is used to identify your supply as domestic, profiles 1 and 2, or business.  it can offer a little information as to the type of meter at the supply point, for example a 00 profile class denotes a half hourly meter.


Meter Time Switch Code


Your meter time switch code tells your supplier how many registers (periods of measure) your meter has and when they measure consumption.  For example you might have a meter with  2 registers measuring consumption from 12am to 6:59 am and 7am to 11:59pm


Line Loss Factor


Your Line Loss Factor indicates the efficiency of the transmission of energy to your meter, whenever power is transmitted over a distance some energy is inevitably lost.  The amount lost can vary but increases as the distance from the main network increases


Area Code


There are 13 separate distribution areas in the UK, each area can have its own meter configurations and unique pricing structure.  These companies are responsible for maintaining and improving the network and cables that deliver energy into your premises.


Unique Identifier


These digits contain a unique code to identify your supply point.

Making use of a complicated mathematical algorithm, these innocuous three numbers ensure there are no errors in your MPAN!

Domestic MPANs

Domestic properties are generally only equipped with supplies that have a profile class of either 1 or 2:


01 ‘Domestic Unrestricted’, where you are charged a standard rate based on your consumption;


02 ‘Domestic Economy 7’ which includes off-peak pricing during certain hours of the night.


If you move into a business premise supplied by one of the above profiles it is still possible to get a business energy tariff although some suppliers may ask that you upgrade your profile to a business class first. If this is the case, get in touch and we will be happy to talk you through the process.


In some cases it is necessary to install a half hourly meter in a domestic property in which case the profile class will be 00 but the good news is you will almost never encounter this when moving house!

Is an MPAN or MPRN the same as a meter serial number?

They are often confused but no, MPANS and MPRNs are very different from meter serial numbers. A single energy supply can have more than one meter and meters can be changed or upgraded during the lifetime of the supply.  This means the serial numbers will change and it is important the supply number is kept separate to enable continuity of billing.   

What is a meter serial number and what does it look like?

A meter serial number, often abbreviated to MSN, is a unique combination of numbers and letters that identifies your meter. It enables energy companies to keep an accurate record of information about a given meter.
