Your MPRN number: what it is and how to find it

08 December 2021 | Matt Mostyn

If you’ve got a gas supply in your home (and let’s face it, you probably have!), you might have come across the acronym “MPRN”. This refers to your Meter Point Reference Number. 

Your MPRN is the number that identifies the gas supply to your home. It’s similar to the Meter Point Administration Number, which is the number that identifies the specific electricity supply for your home. Your MPRN or MPAN is sometimes known as your “supply number”.

Here, we’ll explain what your MPRN is, how to find it, and what you might want to use it for.

What is an MPRN (Meter Point Reference Number)?

An MPRN, or Meter Point Reference Number, is the unique 6 to 11-digit number that identifies the gas supply for your property. It’s also sometimes referred to as the “M Number” or “supply number”. 

Remember, it refers to your gas, rather than your electricity supply. It’s also not the same thing as your customer account number, which your supplier should tell you, nor your meter serial number, which is on the meter. 

What’s the difference between an MPAN and an MPRN?

Your Meter Point Administration Number, or MPAN, is the number that identifies your electricity supply. Meanwhile, your MPRN is connected to the gas supply. 

If you have both an electricity supply and a gas supply, you’ll also have both an MPAN and an MPRN. 

What does an MPRN number look like?

Your Meter Point Reference Number is a number that’s usually between 6 and 11 digits long. 

Unlike your MPAN or your meter serial number, the MPRN won’t contain any letters, just numbers. 

Why you need your MPRN

Your MPRN will most likely come in handy if you change suppliers, or move home. That’s because this number is linked specifically to your property. 

If you’re moving to a new energy supplier, you might need to let your new supplier know your old MPRN as part of the switching process. 

If you’re actually moving home, you might also need to give your new energy supplier the MPRN for your old home when you move. And when you move into your new home, if you’re sticking with the same supplier, they’ll need to update their records with your new MPRN.

How to find your MPRN number

MPRN number OVO gas bill

To find your MPRN, check your latest gas bill. Depending on your supplier, you could see it displayed at the top – or it might be under “details of charges”, or a similarly-titled part of the bill. If you’re an OVO member, it’s usually found in the top right corner of your bill. Find out more about understanding your energy bill in our in-depth guide.

Don’t have a recent bill to hand, or can’t see your MPRN on there? Keep reading to find out what to do. 

By the way, you won’t be able to spot your MPRN on your gas meter – so there’s no need to bother looking there.

How to find your MPRN online

Just visit Find My Supplier and enter your address details, and you’ll be able to find your MPRN in seconds.

How to find your MPRN by telephone

You can find out what your MPRN is by calling the meter number helpline on 0870 608 1524. You’ll have to tell them your postcode and the first line of your address. They’ll be able to let you know your MPRN, and who your gas supplier is if you don’t know. 

How to find your MPRN number without a gas bill

If you can’t find a gas bill to check your number, you can either call the meter number helpline (0870 608 1524), or visit Find My Supplier. With either option, just give your address and you should have your MPRN in just a jiffy.

What to do if you’re not sure who your gas supplier is

You can also check out our handy blog, which gives more guidance on finding your gas and electricity supplier.

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

Definitely not. Your meter serial number identifies your home’s meter. But an MPRN is used to identify an individual gas supply point. 

They might sound similar – but they’re actually 2 very different things. And while you can find a meter serial number on your gas meter itself, you won’t find the MPRN there.

Will my MPRN change if I move home?

Yes. You’ll get a new MPRN if you up-sticks to a new home.

This is because your MPRN is specific to the gas supply to your property. It’s how your energy supplier identifies which supply is connected to your home. So it makes sense that when you get a new home, you get a new number!

If you’ve just moved to a new home and you’re not sure what your MPRN is, try the steps above to find it. 

Will my MPRN change if I switch suppliers?

As long as you don’t move house, your MPRN won’t change. It stays the same even if you move suppliers. That’s because it’s a unique number that identifies the gas supply for your property. 

Switching to OVO couldn’t be simpler

If you decide to switch suppliers to get a better deal, it’s a really simple process. It shouldn’t take more than 21 days, and there’ll be zero interruption to your energy supply during the switchover. Now you know all about MPRNs, it should be really easy to have yours to hand when you switch, so the process runs even more smoothly.
