Best Dual Fuel Deal in Ireland

What are the Cheapest Dual Fuel Deals For Switching Gas and Electricity Providers in Ireland ?

Updated August 1st 2020

At the moment many energy providers offer incentives for new customers such as reduced rates and cashback. Our latest Electricity and Gas Price comparison shows that switching to the cheapest dual fuel deal in Ireland could save around €450 in just one year. This figure would be for average usage households that have not switched before. Of course , households with higher usage could easily save as much as €600 in the first year.

Even if you have previously switched , but have been with your current supplier for more than a year, you could save even more by switching again.

Note: when we compare electricity and gas prices we base it on what might be typical usage in a medium-sized house, using gas for both heating and hot water. ( 11000 Kwh of  Gas and 4200 kWh of electricity a year .)
The prices shown include any cashback offers.

We have compared the prices to those of a household that is currently on the standard rate of Electricity with Electric Ireland and on the standard rates for gas with Bord Gais Energy. The total charge for both fuels for such a household would be €1787 over the next 12 months.

Switch and Save

You should try and treat energy supply like car insurance:- shop around every year and get a better deal. It only takes a few minutes to fill a form in and it could save you a few hundred euros each year.

The main message is ….  if you have never switched and are still on the standard rates from Electric Ireland or Bord Gais Energy  – then switching provider can save you significant amounts of money.

Even if you have switched previously – if you have been with your current supplier for more than a year you will get cheaper offers by switching again.

Switching energy supplier does not involve any wiring changes, pipe changes or disconnections. It just means that a different company is administering your bills. It is still the same electricity and gas coming into your house.

Figures were calculated to the nearest euro  on 1st August 2020  using published tariffs and standing charges on suppliers websites and including VAT, the PSO Levy on Electricity and Carbon Tax on Gas. Cashback offers included in calculations.
The prices given are for new customers only, paying by direct debit.

How to Switch

When you switch electricity suppliers you will need your  MPRN . This is an 11-digit number printed on your electricity bill. If you don’t have it, you can get it by calling ESB Networks on 1850 372 757.
If you’re switching gas suppliers they will need your GPRN . This is a 7-digit number printed on your gas bill. If you don’t have it, you can get it by calling Gas Networks Ireland on 1850 200 694.

Important: the comparison sites don’t include all the cashback offers in their calculations – but they do mention them. So make sure you don’t miss out on the best deals by manually adding any cashback offers onto the total savings to work out the cheapest deal for you.
