Cheapest Electricity Provider Ireland

Electric Ireland  (formerly ESB)  used to be the only domestic Electricity Provider  in Ireland – but since deregulation in 2011 many thousands of households have switched to suppliers such as  SSE Airtricity , Energia or Bord Gais Energy  in order to get cheaper electricity prices.
Many  many thousands more have never switched – and  could save around €200 in just 12 months on electricity bills if they changed supplier.

The electricity switching market is competitive,  with companies regularly doing special offers, discount codes or other promotions such as cashback.
We had a spate of Electricity price rises recently – with Electric Ireland teh last supplier to raise prices (1st Feb).

Who has the Cheapest Electricity Deal in Ireland in February 2018 ?

We carried out a quick comparison of Electricity prices in Ireland for new customers in Feb 2017 and this is what we found:

Low Usage – smaller households will use less electricity. Typical usage for a 1 or 2 person household that doesn’t use electricity for heating – would be 3000kwh per year. On Electric Ireland’s standard rates – paying bills as they arrive – this would cost €792 a year. You could cut this by €216 in the first 12 months by switching to Bord Gais Energy.(€576 including €175 cashback)

Medium Usage
For medium sized homes that use gas , oil  or solid fuel to provide heating and hot water ,  an annual electricity usage  of about 4200 Kwh a year would be typical. This is the avearge national usage. The best deal currently would be to switch to Bord Gais Energy with €175 cashback  – working out at €775 over the first year. A saving of €231 compared to staying on Electric Ireland’s standard rates.

Higher Usage:
Electricity usage will be higher in larger homes with 4 or more occupants –  and in households that use only electricity for heating and hot water.  Consumption figures of 5500 kwH or more per year would be typical for higher usage households .
The best switching deal for someone using these amounts would be with  Energia .  They have a special offer only available online through the Energia website. You need to enter the promo code CHEAPELEC and this will get you 29% off their standard electricity rates for 12 months and  €50 cashback . This would work out at €985 in the first year. (Paying by Direct Debit).  This is a saving of €253 compared to Electric Ireland’s standard rates .

Households with Very high Usage – of 7000kwh or more per year  would be better off switching to the Energia deal available through of 33% of their standard rates. You can use the Switcher site to check prices for your specific usage.


In all cases – after the first 12 months , households should look into switching again to obtain the best deal.

If you also have gas – take a look at  our  Dual Fuel Price Comparison 


Cashback offers are not included in comparison sites calculations – but we include them. So don’t assume the cheapest deal shown on the comparison sites are actually the best available. Cashback offers can often make a big difference to the overall cost.

You should really think about switching your energy supplier every 12 months to take advantage of all these special offers – otherwise most providers will just rput you back on their standard rates after the first year.
It only takes a few minutes – and as we have shown it can save you in the region of €200 just on electricty bills over a year.

  1. Hello!
    Despite the fact that it is such a useful site I didn’t manage to find a place where the electricity and gas bill is explained. But it is probably my neglect….
    Anyway-I’d like to know what the Standing Charge is as well as what PSO Levy is since both charges seems to me very suspicious and do not appear reasonable at all.
    I am getting impression that it is one of many ways how to empty the pockets of ordinary people. Another words from my understanding it is called a looting of the masses!
    So correct me please if I am wrong with this statement and explain in details what does charges I mention above mean!
    Thank you very much in advance!
    Respectfully Ivar.

  2. my friend had his electricity switch off ,cos of a high bill he didnt pay .Can he go to another company and have his electricity switched on and start fresh

  3. Hi, I changed from Electric Ireland (ESB) to Pre Pay Power recently but when I worked out the standing charges PPP charge €29 per month plus other hidden cost, now I did get €150 free credit from them, I was not happy been told they are the cheapest electricity on the market (lies), so within the 2 weeks cooling off period I went back to Electric Ireland and their standing charges are only €17.17 per month with no call out charges or any other hidden charges, I also got €175 free credit as a returning customer after only 1 week with PPP, I would advise anybody thinking of changing to check out the hidden cost they don’t tell you about, or do as I did go to another company and if not happy go back to EI within 2 weeks and get yourself €175 free electricity

    • Did you get the prepay meter with Electric Ireland when you moved back?

  4. How can I find and compare the actual cost of electricity from one supplier to another for a 2 year contract?

    • Most (if not all) of the switching deals are based on 12 month contracts. The vast majority are not based of fixed rates – so any figures we have given assume the charges stay the same for 12 months. Usually – when there is an increase in rates they all increase by almost the same amount.
      You are probably best looking at pricing over 12 months – and then look again in another 12 months for a better deal.
      Good Luck

  5. We have just bought a flat in Dublin and need to put the electricity into our name. How do I find who the existing supplier is – previous owner now living abroad ? Will be letting the flat eventually, so don’t really want to set up a standing order.

    • Normally the estate agent or solicitor should make sure utility suppliers are sorted out . Try contacting them to get the previous owner’s suppliker details. You could try ringing ESB Networks on 1850 372 757 – to get the the MPRN number . They might have details of the supplier. With the MPRN you could ring the various suppliers to see if they are your supplier. Or – just wait for a bill?

    • I’ve been in exact same situation as yourself, previous owner living abroad, contacted management company, no details available, they gave me the care taker number, he sent me the metre image with the serial number, I called ESB networks today and gave them the metre number and they were able to give me MPRN number

  6. I have a small home in Donegal which is empty as I live and work in the UK. The only things in use are the boiler which comes on twice a day to heat the place, perhaps 4 or 5 hours in total. Other than that my mother would be there once a week to check on the place, maybe have a brew and watch some TV. I just got a bill from Electric Ireland for 153.32 for what is essentially an empty house. The last bill was 78.83, which I wasn’t particularly impressed with either. The bill was around 60 euros when I first bought the place over a year ago, which I still thought was kinda steep for an empty house. Can somebody please recommend another supplier who isn’t going to keep ripping me off.

    • Hi Paddy
      It sounds about right if your boiler pump is running for 4 or 5 hours a day. They can use about 1 unit an hour. Add on the kettle and TV – and it soon adds up. Of course the standing charge , PSO levy and VAT make up a sizeable chunk.
      Based on a total annual bill of say €750 with Electric Ireland – you couls cut this by about €120 over 12 months. But you will need to chaeck again in a year to see who is cheaper then. Put your figures in the Switcher website to see the savings. ( I used 3000kwh per year for you)

  7. House in Donegal there more often than in the case above
    Electric Ireland charge just under 54 cents per day over an average 56 day bi-monthly period for low usage charge.Bill circa 70euro actual usage 14euro, rest low usage charge as above, pso, standing charges and vat.

    Any suggestions please

  8. It can be very difficult to get standard rates when enquiring (you usually have to be insistand and persevere as they try to blind you with special offers etc.). The whole competetive market thing is a scam and allows the companies involved to play a complicated shell game. As a consumer I want a straight forward pricing model (no special offers, discounts etc). Low usage is also a disgrace, the existing standing charge is to cover cost of billing etc. Also not very eco-friendly, I’m surprised regulators let them get away with it.
