Cheapest Electricity Provider in Ireland

Many thousands of people in Ireland have never switched electricity provider  – (about 36% of all  households) . By switching to the cheapest electricty provider, those households could save ,on average , €206  in just 12 months on electricity bills.

Electric Ireland  (formerly ESB)  used to be the only domestic Electricity Provider  in Ireland – but since deregulation in 2011 , thousands of households have switched to other suppliers such as  Energia , SSE Airtricity  or Bord Gais Energy  in order to get cheaper electricity prices.

The electricity switching market is very competitive,  with companies regularly doing special offers, discount codes or other promotions such as cashback.


Who has the Best Electricity Deal in Ireland in April 2019 ?

We carried out a comparison of Electricity prices in Ireland for new customers in April 2019 and this is what we found:

Electricity Usage
Cheapest Provider
(Over 1st Year)
Next Best
High (6000kWh)Energia - €1100 BE Energy €1141
Medium (4200 kWh)Energia - €838Electric Ireland €846
Low (3000 kWH)Electric Ireland €625Energia €665

For Higher Usage:
Electricity usage will be higher in larger homes with 4 or more occupants –  and also in smaller households that use only electricity for heating and hot water.  Electricity consumption figures of 6000 kwH per year would be possible for higher usage households .

The  best switching deal for higher usage homes is with Energia . They have a special offer only available through the Energia website. You need to enter the promo code CHEAPESTELEC and this will get you 36% off their standard electricity rates for 12 months.
This will work out at €1100 in the first year. (Paying by Direct Debit).  This is a saving of €299 compared to Electric Ireland’s standard rates (Non DD) .
The next best deal for 6000 kWh usage is from BE Energy at €1141.


Medium Usage
For medium sized homes that probably 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 average national usage.)
The best deal currently would be to switch your electricity to Energia  . This offer works out at €838 ( with a 1 year 36% discount) and is only available  online with Promo code CHEAPESTELEC at the Energia Website.

This is a saving of €206 on Electric Ireland’s standard rates.


Best for Lower Usage :
Smaller households will use less electricity. Typical usage for a 1 or 2 person household that doesn’t use electricity for heating might be 3000kwh per year.
If you are not currently with Electric Ireland for your Electricity supply – then the best deal for lower usage households would be to use Switcher.ie to switch to Electric Ireland and go for their €150 cashback offer . This will work out as a year one price of €625 for 3000kwh.

The next best deal is to switch to Energia . This will work out at €665 in year one  . (This Offer of  36% discount  is only available online with Promo code CHEAPESTELEC through the Energia Website.

Bord Gais Energy will work out at €700 in year one.


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 very big difference to the overall cost- especially for lower usage households.


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 put you back on their standard rates after the first year.
It only takes a few minutes – and as we have shown it can easily save you in the region of €250 just on electricty bills over a year.

  1. Thank you!
    Question
    I have moved into a 2 bedroom home for myself and my 2 children.
    I am keen to switch electricity provider to save money but I THINK the company which is cheapest is what the last occupant was with.

    So would I get the cheap deal if I signed up to them as a “new” client ?

    In grateful appreciation
    Of good reliable advice!!!

    • You should be treated as a new customer and get all the new customer deals. If you are not – then switch to the next cheapest deal.

  2. I’m currently with Energia and my 12 month contract is just up . I use 10000 Kw per year, yes high I know.
    I pay them 200 per month Dd through my bank.
    Who should I switch to as I’m guessing Energia won’t give me the 36% discount I see they give new customers hat come on board.

    • MAybe switch to the Electric Ireland cashback offer , wait for the cashback , them move back to Energia as a new customer. Electric Ireland will chanrge you to leave early – but it will be €100 charge on dual fuel with €200 cashback.

      • Do I have to contact Electric Ireland directly to ask for cashback deal, how long would I have to stay with them before moving back to Energia

      • That’s a good idea.
        To switch back, after the “cash-back”
        I suppose folks do this all the time?

        I am just wondering if I stay with the same electricity provider that the house is currently with,
        *but my name goes in instead of the former tenant* ,
        will that count as a “New contract”…. or not?

      • Not sure – best to ask the supplier to make sure before you sign up. They should treat you as a new customer.

  3. who or what would be the best electric provider moving into a new house, air to water system. 6kwh pump. 2 adults 1 child.
    advice much appreciated
