Verdict
A billing-model choice more than a brand choice. Electric Ireland is the traditional bill-pay incumbent: typically cheaper per unit, with discounts for direct debit. PrepayPower is pay-as-you-go via top-ups: you trade a meaningful price premium for absolute budget control and no bill shocks. If you can manage a monthly bill, Electric Ireland (or frankly any bill-pay supplier in our live table) beats prepay on cost; PrepayPower earns its keep only when avoiding arrears matters more than the premium.
Best for each use case
