Comparison of Electricity Prices in Ireland

By doing a comparison of electricity prices and switching to the cheapest deal on an annual basis, households can save significant amounts of money.
An average household that is still on Electric Ireland’s standard rates could save around €250  in just 12 months by switching supplier.

The electricity switching market in Ireland is very competitive. Most of the energy suppliers regularly have special offers, discount codes or cashback promotions. However, figures from the CRU show that many thousands of people in Ireland have never switched electricity supplier  – (about 35% of all households).

Before 2011 the only domestic electricity provider in Ireland was Electric Ireland. (It was known as ESB then).
However, since the deregulation of electricity in 2011, consumers can now choose from several electricity suppliers such as  Energia, BE Energy, SSE Airtricity, Panda , Bright , Iberdrola or Bord Gais Energy.

At the start of April 2021, we did a Comparison of Electricity Prices available in Ireland for new customers and this is what we found: These prices include any upcoming price increases that have been announced.

See the figures below.

Very High Electricity Usage

A large household with more than 5 or 6 occupants could use as much as 8000 kwh a year. This is almost double the average usage.

The lowest-priced deal is available from Bord Gais Energy – working out at €1382 in year one. (Includes April price increase).

Currently, the second-best switching deal for very high electricity usage homes is available on the Energia website. (Use Promo code ELECTJUNE)
Their offer of 41% off standard electricity rates for 12 months and €35 cashback will work out at €1387 in the first year.
This includes the April price increase.

High Electricity Usage:

Electricity consumption of 6000 kwH per year might be typical for high usage households. Generally speaking, electricity usage will be higher than average in larger homes with four or more occupants.
However, some smaller households that use electricity for both heating and hot water may also have high electricity usage. 

In April 2021 the best switching deal for high usage homes is with Energia only through the Energia website. (Promo code ELECTJUNE)
Their offer is 41% off standard electricity rates for 12 months and €35 cashback. This will work out at €1103 in the first year for 6000kwh. (Includes April price increase)

The second best switching deal for high usage households is with Bord Gas Energy. Their cheapest deal also works out at €1104 in year one

Average Electricity 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 national average usage figure.)

Flogas now has the cheapest electricity deal for switchers. Their “Green Future” deal with €80 cashback , works out at €845 in year one. (For average usage).

Energia has the second cheapest electricity deal – which will work out at €848 over 12 months for this usage , including €35 cashback. You can only get this offer on the Energia Website (Promo code ELECTJUNE).
This figure includes the April price increase.

Best for Low Electricity Usage :

Smaller households will obviously use less electricity. Typical usage for a 1 or 2 person household that doesn’t use electricity for heating might be 3000kwh per year.

Flogas has the cheapest electricity deal for low usage. Their “Green Future” deal with €80 cashback, works out at €642 in year one.

Electric Ireland’s cashback deal works out at €676 over the first year and this is the second cheapest deal.

Switch Annually

In all cases – after the first 12 months with a supplier, households should always compare electricity prices and look into switching supplier again to obtain the best deal.

When we do our Comparison of Electricity Prices, we always include cashback offers in the calculations. However, some comparison sites don’t automatically include cashback in the price. For this reason, do not assume that the deal shown at the top of a comparison site is actually the cheapest one available.

As you can see, cashback offers can make a big difference when comparing electricity prices – especially for lower usage households.

Ultimately you should be planning on switching your energy supplier every 12 months to take advantage of all these special offers. If you don’t switch, your provider will just put you back on their standard rates after the first year.
Switching only takes a few minutes – and as we have shown it can easily save you in the region of €300 just on electricity bills over a year.
