Cheapest Electricity Supplier in Ireland

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

Many thousands of people in Ireland have never switched electricity supplier  – (about 36% of all  households) . By doing a comparison and switching to the cheapest electricty supplier, 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.

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

We carried out a comparison of Electricity supplier prices in Ireland for new customers at the start of October 2019 and this is what we found:

Electricity Usage

Cheapest Provider
(Over 1st Year)
Next Best
High (6000kWh)Energia - €1091Bord Gais €1103
Iberdrola : €1125
Medium (4200 kWh)Energia - €829Bord Gais
Electric Ireland: €838
Low (3000 kWH)Electric Ireland : €616Bord Gais €654
Energa €655

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 CHEAPESTFUEL and this will get you 36% off their standard electricity rates for 12 months.
This will work out at €1091 in the first year. (Paying by Direct Debit). 
This is a saving of €300 in year one , compared to Electric Ireland’s standard rates (Non DD) .

Next best is Bord Gais at €1103 and third best deal for 6000 kWh usage is from newcomer Iberdrola at €1125 .

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 supplier to Energia  . This offer works out at €829 ( with a 1 year 36% discount) and is only available online with Promo code CHEAPESTFUEL at the Energia Website.

This is a saving of €206 compared to 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 to switch to Electric Ireland and go for their €150 cashback offer . This will work out as a year one price of €616 for 3000kwh.

The next best deal is to switch to Bord Gais Energy . This will work out at €654 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 other comparison sites calculations – but we include them. So don’t assume the cheapest deal shown at the top 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.

One thought on “Cheapest Electricity Supplier in Ireland

  1. Is it that old fashioned ‘loyalty’ means nothing anymore?
    there was a time when staying with one insurance or supply company meant slightly cheaper annual costs.
    does any company try to retain customers ‘automatically’ ?
