Flogas vs PrepayPowerWhich is cheaper for you?
Both suppliers run several plans, and the cheaper one depends on how your home uses electricity. Here's who wins for different kinds of household.

Is Flogas cheaper than PrepayPower?▾
On the common usage shapes above, Flogas tends to be cheaper — but that's an average, not your bill. The result can flip on a time-of-use plan, which is why we compare against your real smart-meter data rather than a stereotype.
Why isn't there one "cheapest" plan?▾
Because electricity plans charge different rates at different times of day. A night-saver plan is the cheapest thing going for an EV owner charging at 3am, and one of the dearest for someone home all day. The "best" plan depends entirely on when you use power — so a single league table is misleading.
How do I find which is actually cheapest for me?▾
Link your smart meter to SmarterMeter (free). We rank every plan from every supplier against your actual half-hourly usage — not an average household — so you see your real cheapest plan, not a generic winner.
Can I switch between Flogas and PrepayPower?▾
Yes. Switching electricity supplier in Ireland is free, takes about two weeks, and there's no interruption to your supply — the wires and meter stay exactly the same.
