Electricity and Gas Price Comparison

cheapest gas irelandWhat are the Cheapest Options For Switching Both Gas and Electricity Providers in Ireland ?

Updated September 4th 2018 

Our latest Electricity and Gas Price comparison shows that, for average usage  households ,  switching energy supplier could save as much as €339 in just one year.
 (Someone on €28k a year would you have to work about 30 hours to earn  €339 in take home pay .)

Hundreds of thousands of people in Ireland have never switched energy providers. Recent figures show that around   half of all electricity and gas customers  have never switched supplier.
Of those that have switched to get a cheaper deal  – 51% have just gone back on the default standard rates after the discounted rate ended.

Note: The price comparisons below are based 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 .)

We have assumed that the household 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 would be €1880 in the next 12 months –  if paying bills as received ,not by direct debit.

Switching Dual Fuel – Same Supplier :

  1. The best price for dual fuel is  on the Energia website using the promo code CHEAPDUAL . You will get €50 cashback and 29% off their standard electricity rate and 28% off gas rates for a year. This deal will work out at €1541  in the first year – a saving of €339.
  2.  The best value switching deal for a dual fuel bundle if you are not already with Electric Ireland  – is  from  Electric Ireland . With €200 cashback . It works out at  €1530 over the first year. (Saving of €350).


 Switching to Separate Suppliers for Gas and Electricity  :

The lowest priced option for switching your gas ,  if you are currently on Bord Gais Energy’s standard rates , or with any other supplier,  is to switch your gas over to  Electric Ireland . In the first year this would work out at €680  (this includes €75 cashback offer ).  This is a saving of  €137 in year one compared to the €817 cost on Bord Gais Energy standard rates.

Other prices –    Just Energy €700 ; Flogas €702


The  cheapest electricity switching deal for Electric Ireland customers is currently available from  Energia   at €865  in year one (including €50 cashback).  Available only on the Energia website with promocode CHEAPELEC .This would be a saving in year one of €198 compared to staying on Electric Ireland’s standard rates. (€1063)

If you are already with Energia for Electricity – then the €150 cashback offer from Electric Ireland for new electricity customers works out as he best deal for you at  €869 in year one.

The  combination of the two cheapest separate energy providers  (Energia for Electricity and Electric Ireland for gas)  works out at a total of €1545 in year one. But – switching both fuels to Energia   on the  Energia website using the promo code CHEAPDUAL  will work out slightly lower at €1541  in the first year .



 Note :To get these lower prices with any of the suppliers you will usually have to pay by direct debit and have online billing.

See our Electricity Price Comparison Here

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.
You should try and treat energy supply like car insurance – shop around when the one year contract is over 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.

Switching 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  Sept 4th 2018  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 .

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 printied 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 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.

You could obviously save even more money on your electricity bills by just cutting your energy usage . For  example –  switching any halogen downlighters to Gu10 LED  Low Energy Bulbs (Savings as much as 90%  compared to Halogen 50 watt!)

Insulating your home can also cut your energy bills – see our article about grants for insulation.

    • I am confused – does the comparison include eg the 175 euro cashback from Electric Ireland? I am with Bord Gais for Electric and Flogas for Gas – I don’t care if I need to move to dual or single supplier – I just want the TOTAL cheapest deal but I can’t figure that out if the cash backs are not included….or am I reading it wrong?

      • Cashback is included in all prices we have listed .
        Based on average usage and assuming you are on your current supplier’s standard rates – the best deal for you would be to switch Electricity to Electric Ireland and get the €175 cashback and switch gas to Just Energy .

      • when I put my data into switcher.ie BORD GAIS electricty – Energia is recommended number 1 with 208.26 savings
        Electric Ireland is number 19 on the list with 62.35 savings with the comment underneath as “€175.00 cash-back not include in annual savings”
        So if I add the 175 to 62.35 I get savings of 237.35 which puts it ahead of Energia
        So why does the calculator not do this automatically as I am sure lots of people don’t scroll down to option 19

      • Switcher are not allowed to include cashback in the total price (Government rules) . Our list of prices includes cashback – which is an important point to note.

    • how reliable is Panda for gas and electricty supply ? I thinking of changing to them as they are cheapest on market at moment.

      • The supply is the same as all other providers , same wires and pipes – so it’s jsut the admin and billing that will be different. Once you are set up , there should be very little that could go wrong.

  1. This website is super, thanks a mill.
    Question: I am currently with pre-pay power for my electricity and find it is costing me a small fortune. I am with them over 12 months now and want to change. Thinking of Energia as they seem to be the cheapest. How can I move from Pre-Pay power, as I dont get a bill so where do I get the number to give to Energia?

    • Prepaying is usually one of the most expensive ways of getting electricity. What made you move to them?
      Prepay power will have your mprn number – it must be on documentation from them. Failing tyr calling ESB Networks on 1850 372 757 to get the MPRN

  2. great thanks very much for the quick reply! good to get some straight advice/information, I think with all of the sites its quite difficult to see what your actually saving.

    great site, thanks

  3. I’m moving into a new house for the first time. Do the switcher deals apply to those that will be opening gas/electricity accounts for the first time?

    • All the discount deals and cashback offers are for new customers – so you should be able to get any of them Ciaran.

  4. Hi. This is the just and only website with comparison you can trust. I have used it last year and now again. Won again. Just read and listen and do… guaranteed winner.
    I have worked out all calculations and it’s right. Moneyguideireland is the only one providing full info after discounts.
    Thank you very much.

  5. I’d like to switch to save as I am on standard now but I know I’ll be moving in 5 months. Will I be penalised when I move, since most deals are for a 1 year sign up. Or could I take the contract with me?

    • Suppliers should allow you to move your contract to a new property. We will double check this for you.

      • Energia say they would transfer the contract to the new house without any penalty. Is it Energia you are thinking of switching to?

  6. I am the new owner of a house that has a bulk LPG tank. The previous owner had a contract with Calor. Is it worth switching supplier from one LPG supplier to another, eg Flogas or Tervas?

    • Prices on LPG are not really publicised – each company will negotiate a price with homeowners for the tank and supply. So you will need to get in touch with all 3 and compare prices and contract details. Make sure you look closely at terms and conditions . Let us know what you decide – Thanks

  7. Just one small issue when switching providers, you may be ask to pay deposit of between 200 – 300 euro as new customer with no history.

  8. I ve looked at your info re best deals for gas and electricity, i.e. when you switch. I cannot see advice for a someone moving to a new house(new build). Does the same hold or are the new sign up deals with different providers? I d appreciate your help with this.

  9. I’m with bord gais
    I use 7000 kWh elect approx
    & 26000 kWh gas approx

    What would u recommend
    I like to pay by dd ( level pay )
    but I also like to get a bill in post ( I can keep tract better )


  10. I have a 3 bed semi detached house and I am with Electric Ireland for my gas and electric should I change my provider also i have a electric allowance as I have a senior citizens pension will that be easy to transfer to a new provider. Mary

    • Hello Miriam
      If you have been with Electric Ireland for more than a year – then you will get a cheaper deal by moving. If you want gas and elec from one supplier – your best option is currently Energia using the promo code CHEAPDUAL
      The Electric allowance will still be given by Energia – but it will be paid to you direct to your bank account instead of being deducted from your bills.

  11. i signed up to eleactric ireland electricity last month and got a €175 cashback offer. im with flogas for my gas, can i get the €175 cashback offer if i switch my gas to electric ireland too?

    • The €175 cashback is supposed to be only paid once per customer. But maybe wait a month or two and try it – you never know, it might work . Let us know if it does.

  12. I am moving into a new build and was going to stick with electric ireland pre pay power only because we have an outstanding bill due to many years of estimated bills. Is this my only option in the new build house to stick with electric Ireland pre pay for the next year until we have paid what we owe. ?

  13. Hi there, I am in my new place nearly a year. I am using Energia for electricity and Flogas for gas and worked out I use approx. 533KWh/€292 of gas and 258KWh/€463 of electricity per year. Would I be best to go to a dual supplier or change to different suppliers of both? Bit confused, thanks.

    • Hi Aoife, based on those charges you gave –
      Your best option currently is to switch Electricity to Bord Gais (cost €247 in year one incl 175 cashback)
      switch gas to Electric Ireland – working out at just €98 in year one ! (incl €175 cashback)

      Assuming you have no contract penalties to pay your existing suppliers. If you have been with them more tha a year you should be OK . I would do it soon because these cashback offers might not be around for much longer.

    • From my calculations i use 10315kWh of GAS and 4325kWh of Elec.

      I am with sseairtricity and just discovered if i had An Post Smart Account (Which i might just open and transfer money into pay the bill each month) i can get 10% MoneyBack rebate. Would it be worth my while trying to get a better discount off sseairtricity or follow your advise and move to Energia

      • You current annual bill with SSE should be about €1430 – so 10% cashback with An Post is worth just €140. There is a €5 per month fee with An post – which comes to €60 a year , reducing that cashback benefit to just €80.
        (See http://www.moneyguideireland.com/post-smart-current-account-charges.html

        You can easlily save more than €80 in a year by switching to Energia for both fuels (ABout €332 savings in year one if you go to the Energia website using the promo code CHEAPDUAL http://www.moneyguideireland.com/go/Energia-Direct/ )

        Or if you prefer – get electricity from Bord Gais and Has from Electric Ireland to take advantage of €175 cashback from eacch of them .

        • Thanks for taking the time to reply to my question.

          Does the new offer from onebigswitch with Bord Gais make any difference to your reply. I only found it today

        • The separate deals from BG and Electric Ireland will be cheaper than the One Big Switch deal for dual fuel.
          Your usage is close to average – and for average usage the “OBS” dual fuel deal works out at €1400
          The two offers from BG and Elec Ireland with cashback work out at €1302 for the same usage.

          Plus – they seem to store a lot of data about you and y maight be sent lots of third party emails (see https://www.onebigswitch.ie/privacy-policy)

    • thank you so much for this information. I am market to switch my gas and electricity. I am currently with energia ( 26% off) and flow gas ( 20% off) and it is finishing in april.

      So if I understand correctly, best deal for me is
      1. switch electricity to electric ireland ( get 175 euros)
      2. switch gas to just energy

      or should I choose
      1. for gas: electric ireland ( get 175 euros saving)
      2. for electricity : Bord Gáis Energy ( get 175 euros saving
      can you please help?

      • The last option will be best – Gas – Electric Ireland ; Electricity from Bord Gais
        (Because of the 2 cashbacks)

    • HI thanks for the info but would your recommendations be similar in this scenario:
      Currently with Bord Gais for Gas and Airtricity for Electricity. Reading your advice, I’m thinking it would be better to switch to Electric Ireland for Gas and Bod Gais for Electricity but would Bord Gais still give you the 175 euro? Otherwise would it be best to go for Electric Ireland for both Gas and Electricity? Thank you!

      • Bord Gais will give you the cashback for signing up as a new electricity customer with them. Do the switch of the gas first maybe – just to be sure , then switch the electrity afterwards. (But you shouldn’t really have to do this)

    • As a first time buyer ( 2nd hand house ), with no current supplier. Would you still recommend BG to electric and EI for gas ? – To maximise the two cash back options..

      • Also, there is an electric option with BG, either ‘10% discount + 175eur cash’ or ‘24% discount’.

        • If you are using less than around 6000 kwH a year of electricity s – then the 10% off with 175 cashback will be the best deal. Average usage is 4200kwh .

      • Yes – it works out the best deal. Check again after a year though for the best deals again.

    • I’m with Energia for the Electricity on the smart choice electricity and I’m with FloGas with 20% direct debit discount. I worked out the Dual Just Energy package is cheaper but with the €175 cash back with Electric Ireland am I better of going with two different providers. Over a year with my current suppliers so hoping to change in next day or two and stick with Direct Debit plan

      • The €175 cashback offers from Electric Ireland on gas and from Bord Gais on Electricity are currently the best deals for low to medium usage .

        • Thanks for your prompt reply, I’d use less than the national average as its a single household so is it still best to go with.

        • Yes – lower usage households will see the biggest savings by going for these cashback offers.

      • The deals shown are all available for new customers – so a new connection should be able to get the same deals. Many people assume they have to go with Electric Ireland for electricity and BG for gas – but they don’t have to.

    • Just switched from Airtricity to Energia dual fuel DD e billing and then noticed your comments on different suppliers.
      Last year: Elec 5870kWh Gas 11551kWh
      Should I have gone Elec to Bord Gais and Gas to Elec Ireland.
      What is difference over first year.

      • For those usage figures it would cost you €1665 with Energia (assuming you went for the promo code offer with €50 cashback)
        With Electric Ireland – gas would work put at €558 (inclusing the €175 cashback)
        With BGE – Electricity would work out at €1052 in year one (including €175 cashback) but Energia’s Electricty on it’s own would be €1040 (29% off and €50 cashback)

        So the lowest price would be by going with Energia for Elec and Electric Ireland for gas – a total of €1598
        Cheaper by just €67 over the year than the dual fuel deal from Energia. Not too big a difference.

    • Hi thanks for your great website and your quick replys.
      I’m nearly a year now with Electric Ireland for both Gas and Electricity.
      Whould you recommend changing to BG for gas/electricity and what provider for the other one? And also how can i find out our anual usage on both gas and electricity please? Is it by adding the values from each bill?
      Thanks in advance.

    • Hi guys.

      Curious to hear your opinion on getting Bord Gais via OneBigSwitch – I’ve been running the numbers and it appears cheaper than everyone else (including cash back offers etc) – seeing electricity at 11.68 cent/kWh (ex VAT) and gas at 3.592 cent/kWh (ex VAT). I’m approaching the end of my contract was going to switch to them (Bord Gais) directly, but this route appears more cost effective, especially seeing I use in excess of 20,000 kWh of gas each year.


      • The OBS offer is working out at €1400 in year one for average usage. An average user would get a cheaper deal by going direct to Electric Ireland for gas and to BGE for electricity , getting the €175 cashback from both – working out at €1302 in year one. You must have a big house if you are using that much gas in a year (or a badly insulated one) . If that figure is correct – the gas charges with OBS would be about €33 cheaper over year one than going direct to Electric Ireland. BUT – you have to get electricity off them to and would probably save more than that €33 by going direct to BGE for your electricity and getting the €175 cashback. Hope this helps ?

        • A badly insulated one, sadly… thanks for the reply, appreciate it. Because we use so much gas, it does work out a bit cheaper with OBS… by about €50 by our averages. However I’m hesitant to go to OBS now, not much contact info and I’m finding they take too long to reply to emails. It’s unfortunate, as it would have worked out the best for us. Cheers

    • Hi there,

      would appreciate some guidance – we used 6659 kwh of electricity over the last 12 months and 21159 units of gas and we are with Energia for both – on Smartchoice as our dual fual offer expired some months ago. What would you recommend for us – we intend to upgrade our insulation on our old house so our usage should go down also!!

      Thanks so much

      • With high usage such as this – the best deal we could find for you would be to go dual fuel with Panda Power via Switcher – they are offering 28% off thir gas and electricity standard rates. This would work out at €2256 over 1 year with your usage. Going with the best deals from BGE for Elec and Elec Ireland for gas would work out at €2274. Put the figures in to Switcher.ie and see for yourself.

    • Hi I am with electric ireland and spend about 700 on gas and 700 on electricity . Would I get a better deal elsewhere?

      • Based on those figures – you would be better off moving your Gas to Flogas and Electricity to Bord Gais Energy – 175 cashback). Total cost in year one = €1089 . Saving of €311 . If you want to go dual fuel from one supplier – the €200 cashback offer from SSE would work out at €1134. See figures on Switcher website

    • Hi, any help would be very much appreciated. One adult and two kids living in a small apt what would be the best deal to go with it? I am out of contract at the moment with SSE alectricity (both gas and electricity), by comparing website I should go with energia but I am confused on the cash back not included .. any help please?

    • Hi, I spend approx 850 on Elec and 800 on Gas per year. Currently with Flogas for Gas, and Elec Ireland for Elec – contract up over next few days for both. Im thinking of going with Elec Irel for Gas (get 175 back) and Bord Gais for Elec (again get 175 back) – alternatively could go with panda as they have 28/29% discount offer on switcher. What do you think is best option at present?

      • Yes – the two cashback offers you mention will work out the cheapest over 12 months – aven after the upcoming price increases. Switch the electricity to BGE first – so that you will be sure to get the 175 cashback when you go to Electric Ireland for the gas.

    • Hi, shopping for around for electricity and gas really confuses me. We are moving into an A rated house so I’m expecting our energy bills to be less than the average consumption figures.
      My question is do all suppliers have the same standard rates and the only difference between plans are the discounts?

      • The standard unit rates do differ between suppliers – but the best way to get good deals is to take advantage of the offers. For low usage households – the cashback deals will work out best. (Gas from Elec Ireland and Electricity from Bord Gais)

    • Hi I’m with electric Ireland (4years!) and have pay as you go meters for both gas and electricity.. I didnt want another bill in the door thats why I went with pay as you go. Ready to switch now to bill pay/direct debit. I’m thinking a dual fuel deal but can’t decide between energia & bord gais? Do I need to contact electric ireland about payg meters or can I just switch as normal? Thank you!

      • For an electricity Pay As You Go meter installed by Electric Ireland – they can just send a code to deactivate the Pay As You Go mode. This is free.
        For gas Pay As You Go meters, there is a removal fee of about €200 – unless things have changed in the last few months.

        You will need to contact Electric Ireland to get the meters converted/removed.

        If you are deciding aboutnew suppliers – then just go for the cheapest options as listed in the article above.

    • I switched my gas supplier to Flogas last February on a 12 month contract. Since they have now increased their prices by more than most other suppliers they may well be more expensive than my alternatives.

      Do I have to remain with them for the remainder of the 12 month commitment or can I now switch again because they have made a change to the rates which I agreed to when I entered into the contract with them ? It would be strange if the 12 month commitment was binding on me but not on them……

      • The contract would not have stated that the unit rates were fixed. They can increase charges. Some suppliers do offer fixed rate contracts – such as “Just Energy” – but these rates are typically higher than variable rates with other suppliers.
