Your GPRN number or, Gas Point Reference Number, is a unique 7-digit code that identifies your home's connection to the gas network. Your GPRN number can be found on the top of any gas bill or by calling Gas Networks Ireland on 1800 464 464. Your GPRN number is important to have when you want to switch gas suppliers, or to report a fault with your gas supply.

What Is a GPRN Number?

A GPRN Number, or Gas Point Reference Number, is a 7-digit code that identifies your home's connection to the gas network. While bills from gas providers can be different, you will generally find it in the top right-hand corner of your bill.

Each home will have a unique number and will look something like this:

10 006 759 704

The first two digits indicate the system operator (usually 10 in Ireland), the next 7 digits are sequentially generated, and the final digit is a “check” digit (which is used to detect simple errors in a series of digits).

Much like MPRN numbers for electricity and smart meters, GPRN numbers in Ireland are fixed to a certain location and are not unique to you or your energy supplier. If you move home, your GPRN number will change to that of your new property.

How Do I Find My GPRN Number Without a Bill?

If you don't have a bill at hand and don't know the GPRN number of the property, you can find it by:

• Asking the previous owner if you have purchased the property.
• Ask your property manager or the landlord if you are renting the property
• Contact Gas Networks Ireland and ask for your GPRN number.

Gas Networks Ireland can be contacted on 1800 464 464 open Monday to Friday from 8 am to 8 pm, and Saturdays from 9 am to 5:30 pm.

Why Do I Need To Know My GPRN?

It's important to know your GPRN number for several reasons, including:

1. Gas Billing
   Your GPRN number is used by natural gas suppliers to accurately identify and bill your gas usage. It ensures that the correct gas consumption is associated with your account.
2. Gas Switching
   If you decide to switch your gas supplier, providing your GPRN number to the new supplier is essential. It allows the new supplier to initiate the transfer process smoothly and ensures the continuity of your gas service.
3. Gas Meter Reading
   Sometimes, you might need to provide meter readings to your gas supplier with your GPRN, but it's usually not common unless you are trying to identify the property.
4. Reporting a Fault
   If you experience any issues with your gas supply, such as leaks or disruptions, providing your GPRN number helps energy companies identify the specific gas connection and address the problem efficiently.
5. General Gas Inquiries
   When contacting gas suppliers or Gas Networks Ireland about your gas connection, mentioning your GPRN number helps them locate your property quickly and provide accurate information.

How To Get a GPRN Number?

If you have a new gas connection installed or are moving into a new build, you first need to get a GPRN number for the gas to flow into your property.

You’ll first need to get in contact with Gas Networks in order to get you set up.

Once you have the GPRN number, you can contact your gas supplier to arrange for the gas connection to be completed. Your gas supplier will then send out an engineer to install the gas meter. 

The engineer will need the GPRN number to access the meter.
