Switch and Save Every Year

The central message is that some average-usage households could save over €700 in just one year by changing electricity provider.
Even if you already switched your electricity supplier more than a year ago – it is worth your while switching again.  You should treat energy supply like insurance, 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.

You should register at One Big Switch which often arranges good deals with energy providers for members. It’s free and once you are registered they will let you know about any energy deals they have agreed with suppliers.


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.
We advise comparing electricity prices after the contract is up and switching 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.
