Find my cheapest planBord Gáis vs Flogas — frequently asked
Is Bord Gáis cheaper than Flogas?▾
On the common usage shapes above, Bord Gáis 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 most expensive 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 Bord Gáis and Flogas?▾
Yes. Switching electricity supplier in Ireland is free, can take a few weeks, and there's no interruption to your supply — the wires and meter stay exactly the same.
