It has been mentioned many times on AAM that the discount rate is not what we should be looking at but the price per unit and also the annual charge which can vary a lot from one company to another.
Most people move each year to avoid this existing customer problem.
I have found of late that the deals on Bonkers and Switcher are not great and it is better to check both those and the rates on the individual company's website.
It pays to run your electricity usage figures through
www.energypal.ie also.
From a customer service point of view I would rate the companies as follows from the ones that I have used plus I don't have an EV/panels/gas heating:
1. Energia - excellent but dearer
2. Electric Ireland - good, but last time I checked figures, which is a couple of months ago, were dear
3. Bord Gais - cheaper but can be troublesome and time consuming to deal with
