If you’re out of contract, you can easily switch energy supplier and save hundreds annually on your energy bills. In this guide, we outline the steps involved in making the switch.

This guide outlines how to switch gas and electricity prices using our energy comparison service. This is the third guide in our eight-part energy switching series, which we’ve created to help you make the most out of our energy services. You can find the rest of the guides in this series linked at the end of this article.

Switching energy supplier is easier than you think. Once you’ve carried out an energy comparison and have selected the gas and/or electricity deal that best suits you, you can proceed with the switching stage.

Before reading this guide, we’d recommend taking a look at our other guide on how to compare gas and electricity prices if you haven’t already done so, which outlines how to review the options available to you.

Step 1 - Account

After you complete the final step of the comparison stage using our free energy comparison tool and click the ‘proceed’ button on your chosen energy deal, you’ll be asked for some personal information.

Your details

To proceed with your switch, we’ll need the following information from you:

  • Your full name
  • Your email address: We need your email address to send you a confirmation email.
  • Mobile number
  • Your home telephone number: Please leave this blank if you don't have a landline
  • Date of birth: You must be over 18 years of age to complete the switch.

Step 2 - Supply

Your meter numbers  

To complete your switch, you’ll need to provide us with information about your gas and/or electricity meter.


Your MPRN (Meter Point Reference Number) is an 11-digit number that indicates the exact location of a property’s connection to Ireland’s electricity network.

Your MPRN is usually printed on the top of your electricity bill. However, the numbers are located in different sections of the relevant bills, depending on the supplier. 

Your electricity meter reading

You’ll need to let us know your electricity meter reading. If you don’t know your meter reading on hand, you can provide it later. If you need a meter key to open your electrical box let us know and we'll send one out to you. 

Unsure of how to read your meter? Take a look at this guide to find out how

Meter readings will differ depending on the type of meter you have, e.g. standard, NightSaver, smart meter, pay-as-you-go, etc.

If you have a NightSaver meter, you’ll need to input both your daytime and night reading.  

If you have a new meter installed, enter 0. 


Your GPRN (Gas Point Reference Number) is a unique 7-digit code that identifies your home’s connection to the gas network.

Your GPRN is usually printed on the top of your gas bill. However, the numbers are located in different sections of the relevant bills, depending on the supplier. 

It's important to note that both your MPRN and GPRN are attached to the location of your home and not to your supplier or you personally. So even if you switch energy supplier these numbers will never change.

Your gas meter reading 

Similar to electricity above, you’ll need to let us know your gas meter reading. If you don’t know your meter reading on hand, you can provide it later. 

Once again, meter readings will depend on the type of meter you have installed. If you have a new meter installed, enter 0. 

Your address

We’ll need to know the following information about your address:

  • You’ll need to tell us your current address for correspondence.
  • Let us know if you have lived at this address for over 14 months.
  • Let us know if you own the home you live in. If you select ‘no’, you’ll be prompted to input information about your landlord. This includes their name and their telephone number.

Step 3 - Your payment details 

You’ll need to provide your bank account deals to proceed to the confirmation stage of your switch.

Name of the account holder 

Let us know the name of the bank account holder. This may be in single or joint names. 

Choose to use IBAN or Bank Sort Code

Here you’ll have a choice about whether or not you’d like to submit your IBAN or use your bank’s sort code and your bank account number.  

  • IBAN: ​​This is a 22 character international bank account number, which can be found on your bank statement 
  • Bank sort code and bank account number: Alternatively, you can use your bank’s 6-digit sort code and your bank account number. 


You’ll need to confirm that you are the bank account holder and that you agree to provide the above banking information for payment purposes.

Step 4 - Confirmation

Do you need to sign up for the Priority Services Register?

You will need to indicate whether anyone residing at the property is dependent on life-supporting medical equipment, such as an Oxygen Concentrator, or is dependent on any assistive technologies, like environmental control transmitters.  

If your answer is ‘yes’ and someone does rely on these technologies in your home then you will need to fill in a Priority Services Support application form. This form will be sent to you by your new supplier and you will have to complete it and return it to them. 

Do you require any special services? 

Suppliers and Network operators understand that certain customers may require additional services to assist their needs. 

For instance, if you have a visual or hearing impairment you can request a range of services, from braille bills to bills typed in a large print from your energy supplier. 

In this section, you can indicate whether any of the following categories covered in the special services register to apply to you. These categories are:

  • Language difficulty
  • Speech impairment
  • Advancing age
  • Hearing impairment
  • Dexterity impairment
  • Vision impairment 
  • Learning difficulty
  • Mobility impairment
  • Mental health

Once you have completed these steps it is time to move on to the last stage of the switching process.
