Business electricity: what is my MPAN and where do I find it?


To get an accurate business electricity quote your MPAN or meter point administration number is vital. But what and where is it?

What is an MPAN and where do I find it?

As you can see from the image above the 21 digits that make up the MPAN, sometimes called the Supply Number or S number, all tell us something.

Profile class

Starting in the top left hand corner, the first two numbers tells us the profile class, which shows whether it’s a domestic or business meter. If the number begins 01 or 02 then it’s a domestic meter. This doesn’t mean we can’t switch the supply but we will need to have proof that a business runs from your home. A typical business meter begins with either 03 or 04 and those beginning 05-08 refer to maximum demand meters. These are capable of supplying greater amounts of electricity than 03 profiles.

These numbers can also tell us if the meter is a day and night meter. Some customers are charged different rates during certain hours of the day.

Half hourly meters, which are associated with large consumption rates will have a profile class of 00.

Meter time switch code

The next three numbers tell us the meter time switch code. This tells us how many meters or dials your electricity meter has and what times they operate. If your meter has two registers one of them will record day usage and the other will record night consumption.

Line loss code

The next three digits make up the line loss code, which shows how much the distribution company is likely to charge the supplier for using the cables and network in your region. There are many different distribution networks across the country and how much they charge depends on the area your business is based and therefore will impact on your energy prices.

Distribution ID and meter point ID

The next two digits show us the distribution ID. This tells us which distribution company transports your electricity to you.

The meter point ID number is really self-explanatory – it allows us to identify the meter. It’s a unique number within the distribution area.

Check digit

The final three numbers are called the check digit. This number is calculated using the distribution ID and the meter point ID. As the name suggests it allows other systems to check both the numbers.

As you can see the MPAN can provide us with a great deal of information. But giving us this number doesn’t allow us to switch your meter – this won’t be done unless you ask us to. However, your SwitchMyBusiness.com personal switcher will be able to use this number to provide you with accurate energy quotes before guiding you through the whole switching process.

Super helpful and easy to work with

"Recommend this company in a heartbeat - Nicole Borneuf was super easy to talk to, was not pushy in the slightest, very helpful and replied with all my questions very professionally and did all she could to help. I had to deal with a few companies to sort my business energy out, all but Nicole were too pushy for my liking and I refused to follow through with them. Thank Nicole - you are a credit to your company, thank you for making the stressful energy change so easy."

An Extremely Competent Company

"Switch my business has not only helped my SME secure a good energy deal for the second year running but Jessica swiftly found a alternative supplier for me when I was let down on the day of switching by the new contractual provider I had chosen some 4 months previously. Being suddenly out of contract and without provider is everyone's energy nightmare. Greatest thanks."

Quick & Easy

"Kabibi was very helpful and the whole process was very efficient. The one small reservation I had was that I was phoned up by Kabibi almost immediately having received my online quote - which wasn't enough time for me to finish reading the quotes! Fortunately she was able to assist me in a greater savings on both Gas & Electricity, and so as long as the switchover is seamless I will remain very happy with the service."
