Electricity Suppliers in Ireland

Helps you compare electricity suppliers, tariff types and switching options in Ireland so you can pick the best deal for your home.

Ireland's electricity market is fully deregulated — ESB Networks owns and maintains the physical wires and your meter no matter who you're with, but you're free to choose which supplier bills you and at what rate. Switching doesn't touch your physical connection or cause any interruption, so there's no real downside to shopping around.

  • communitypower.ie

Understanding the tariff types

  • Standard (24hr): one flat rate for every unit, all day. Simplest to understand, usually not the cheapest if you can shift usage.
  • Day/night (NightSaver-type): cheaper overnight rate, higher day rate — worth it if you can run washing/dishwashers/EV charging at night.
  • Smart (day/night/peak): requires a smart meter; adds a more expensive "peak" evening band on top of day/night, in exchange for a lower off-peak rate.
  • EV tariffs: a dedicated cheap overnight (or scheduled) window sized for EV charging, usually needs a smart meter and sometimes a second, EV-only, circuit/meter.
  • PAYG (Pinergy, PrepayPower): top up in advance rather than a monthly direct debit/bill — useful for tight budgeting, no credit checks or deposits.

Sizing solar panels and a home battery

If you're thinking about solar PV and/or battery storage to cut your bills further — especially useful alongside an EV or a smart/night tariff — homebattery.ie lets you enter your household's usage (and EV charging habits, if relevant) to get a recommended solar panel and battery size, estimate what you'd save against your current tariff, and compare EV charging costs across the different smart/EV plans above.

Note: the SEAI Solar Electricity Grant is only available for homes built before 31 December 2020, so Hawk's Bay houses don't qualify — factor quotes without it.

Switching suppliers

  • Switching is free and typically takes about 1–2 weeks; your supply is never interrupted during the switch.
  • The market is regulated by the CRU (Commission for Regulation of Utilities) — a good place to check licensing if a supplier is unfamiliar.
  • Comparison sites like bonkers.ie and selectra.ie let you compare unit rates and standing charges side by side.

A few practical tips

  • Compare the unit rate and standing charge together, not just a headline "% off" discount — discounts are often only for the first 12 months.
  • Check what happens after year one — most discounted plans revert to a higher standard rate; note the date so you can switch again before then.
  • If you have (or plan to get) a smart meter, day/night and EV tariffs are usually only worth it if you can actually shift a good chunk of usage to the cheap window.
  • Prices and plans change — the details above are correct as of mid-2026; always confirm current rates directly with the supplier or a comparison site before switching.
