Switch and Save Every Year

The central message is that you can easily save around €200 to €300 in one year by changing your electricity provider.
Even if you switched electricity supplier more than a year ago – it is worth your while switching again.  You should treat energy supply like insurance and shop around and look for the cheapest electricity deal once a year. Loyalty does not pay.

The main energy price comparison sites sometimes don’t automatically include cashback offers in their calculations. The figures in the table above do include all cashback offers.

Most suppliers will sign you up for a 12-month contract. You will usually be charged an exit fee of around €50 if you leave early.
Our advice is to compare electricity prices after the contract is up and switch again to the supplier with the cheapest electricity prices in Ireland. Sometimes paying the exit fee could be worth it if a new supplier is offering a very good deal.
