Find your MPRN - Quick Summary

Your Meter Point Reference Number (MPRN) is a unique 6 to 10 digit code that identifies the gas supply point for your business premises. It stays the same even if you switch suppliers because it is tied to the location rather than the account.

It is the specific identifier for the pipe that brings gas into your building. Whether you are a small shop or a large industrial site, knowing this number is the first step toward getting accurate gas quotes for business.This guide explains exactly how to track down your MPRN and how to tell it apart from other similar numbers on your meter.

Locating your MPRN on a recent gas bill

The fastest way to find your MPRN is to look at a copy of a recent business gas bill. Every supplier is required to include this information on your statement. However, they do not always make it easy to spot. Different companies use different labels for the same piece of information.

You should look for a section often titled "Details of Charges" or "About your supply". The number itself is usually between six and ten digits long. It will consist only of numbers and will not contain any letters. If you see a code that includes letters, you are likely looking at your electricity supply number (MPAN) or your meter serial number instead.

Common labels you might see on your bill include the following terms.

If your business has recently moved into a new unit, you might not have a bill yet. In this case, you can ask the previous tenant or the landlord for a copy of an old statement. This is often the most reliable way to ensure you have the correct data before you begin a business gas price comparison.

Having this number ready allows you to get much more accurate pricing. When suppliers provide quotes, they use your MPRN to check the technical details of your connection. This includes things like your annual consumption and the type of meter you have installed. Without it, any quote you receive might just be an estimate that changes later.

Finding your MPRN without a bill

Sometimes bills go missing or you might be taking over a premises where the previous records are unavailable. If you do not have a bill, you still have several ways to find your MPRN. You do not need to wait for a statement to arrive in the post.

The most common method is to use the "Find My Supplier" online tool. This is a central database where you can enter your business postcode and address to see who currently supplies your gas. Once the search results appear, they often display the MPRN alongside the supplier name. This service is designed to help businesses and households identify their supply points quickly.

If the online tool does not work for your specific address, you can call the National Grid Meter Number Helpline. They maintain a national database of every gas connection in the country. You will need to provide your full address and confirm that you are the authorised person for the business. They can then read the number out to you over the phone.

Another option is to check with your local Gas Network Operator. These are the companies responsible for the actual pipes in your region. They are different from the company you pay for your energy. You can find out who your network operator is by checking the Energy Networks Association website.

Pro Tip

If your MPRN starts with the digits 74 or 75, your gas is supplied via an Independent Gas Transporter (IGT). This simply means your local pipes are managed by a private company rather than the main national network. Some suppliers charge a small extra fee for IGT connections, so it is helpful to know this when you compare business gas prices.

If you are currently in a contract but just cannot find your paperwork, your current supplier is obliged to give you this number. You can call their customer service team and they will verify your account before giving you the MPRN. This is a good time to check if they have your correct business name and address on file as well.

The difference between MPRN and meter serial numbers

A common mistake business owners make is confusing the MPRN with the Meter Serial Number (MSN). While they both relate to your gas supply, they serve very different purposes. Mixing them up can lead to delays when you try to switch or set up a new account.

The Meter Serial Number is a unique ID for the actual physical box on your wall. It is printed on the front of the meter, often near a barcode. If your meter is old and gets replaced with a new smart meter, your Meter Serial Number will change. It identifies the hardware itself.

The MPRN is different because it identifies the location. Think of the MPRN as the permanent address of the gas pipe. Even if you rip out the old meter and install a brand new one, the MPRN stays the same. It is linked to the land and the building.

To help you distinguish between the two, here is a quick comparison of their characteristics.

When you are looking at your meter, do not look for the MPRN. It is very rarely printed on the physical device. If you see a series of numbers and letters like "G4K012345678", that is your serial number. If you provide that number when asked for an MPRN, the supplier's system will likely flag it as an error.

Understanding how business gas supply works in the UK involves knowing these technical distinctions. It ensures that when you are shopping around for new rates, you are giving the experts the right information to identify your specific site.
