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 also 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.
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.
