How to find out your energy supplier in Ireland

How do I find out who my electricity supplier is?

You can find out who your electricity supplier is by looking at the details of your energy tariff on a recent energy bill.

If you don’t have a bill available, or if you’ve just moved home and aren’t sure which utility company supplies your new property, you can:

• Call ESB Networks on 1800 372 757

How do I find out who my gas supplier is?

As with electricity, you can find out who your gas supplier by looking at the details of your energy tariff on a recent energy bill.

If you can’t find a recent bill, and no-one you live with knows who your gas supplier is, you can:

• Call Gas Networks Ireland on 1800 464 464
• Use the Gas Networks Contact Us form

How do I find who my dual fuel supplier is?

If you have both gas and electricity in your home, you may be signed up to the same supplier for both. If you have just moved home or can’t find a recent bill contact ESB or Gas Networks using the contact details above.

Your supplier will be able to confirm whether you have a dual fuel tariff or stand-alone plan.

What if I don’t have a supplier yet?

Alternatively, you can sign up as a customer with any electricity, gas or dual fuel supplier who will organise the connection to ESB Networks or Gas Networks Ireland for you.
