Find my cheapest planSSE Airtricity vs Energia — frequently asked
Is SSE Airtricity cheaper than Energia?▾
Not always — it depends on your home. SSE Airtricity works out cheaper for some usage patterns and Energia for others (see the breakdown above). An EV owner who charges overnight and a household that's out all day can get opposite answers from the same two suppliers.
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 SSE Airtricity and Energia?▾
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.
