Cheapest Dual Fuel Deal in Ireland

What is the Cheapest Deal For Switching Gas and Electricity?

Most of the energy suppliers in Ireland offer deals for new customers such as reduced tariffs or cashback. Our latest comparison of the best dual fuel offers shows that switching to the cheapest dual fuel deal in 2021 could save an average usage household in Ireland around €500 in just one year.

This first-year savings figure of €500 is for dual fuel households that have never switched before and are paying the standard rates with Electric Ireland and Bord Gais Energy.
The total charge for both fuels for such a household would be €1871 over the next 12months.
Households with higher usage could easily save in the region of €700 or more in the first year.

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

Note: when we compared gas and electricity prices we based 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.

The current best deal on gas alone is from Flogas. Over one year of average usage this would work out at €602.


Energia has the cheapest Electricity deal for switchers. For average usage their “Home” deal will work out at €780 in year one , including their €35 cashback. Use Promo code ELECTJUNE to get this offer on the Energia Website . It’s not available elsewhere.

The combined price of these two separate suppliers comes to €1382 – therefore, for average usage, it works out cheaper to go with the Dual Fuel bundle from Flogas or Energia.

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.

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 to the Cheapest Dual Fuel Bundle 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.

Prices were calculated to the nearest euro on 14th February 2021  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.
