Cheapest Electricity Supplier in Ireland

The electricity switching market is very competitive,  with companies 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 June 2019 ?

We carried out a comparison of Electricity supplier prices in Ireland for new customers in June 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 : €624Energia: €664

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 €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  supplier to Energia  . This offer works out at €838 ( 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.

The next best deal is to go for Electric Ireland with €150 cashback . This works out at €847 in year one.

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 €624 for 3000kwh.

The next best deal is to switch to Energia . This will work out at €664 in year one  . (This Offer of  36% discount  is only available online with Promo code CHEAPESTFUEL through the Energia Website.

Switching to Bord Gais Energy’s best deal will work out more expensive 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 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.
