Switching electricity supplier is the highest-return, lowest-effort thing you can do about your energy bills in Ireland — and most people never do it. Here’s exactly how, in a few minutes.
Short answer
Switching is free, takes minutes, and there’s no interruption to your supply. Moving off a standard rate onto a new-customer deal commonly saves a household a few hundred euro a year.
Why switching saves so much
Irish suppliers compete for new customers with discounts that last a set period (often 12 months). When that period ends, you roll onto the standard rate — the expensive default. Staying put = overpaying.
What you need
- A recent bill with your MPRN (the meter point reference number).
- Your estimated annual usage in kWh (also on the bill).
Step by step
- Compare on a CRU-accredited price comparison site (such as bonkers.ie or switcher.ie).
- Enter your actual usage for an accurate estimate — not the site defaults.
- Compare the estimated annual bill, not just the headline discount, and check the standing charge.
- Pick a deal and complete the switch online — the new supplier handles it.
- Give a meter reading on switch-over day.
- Put a reminder in your calendar for when the discount ends.
Mistakes to avoid
- Only looking at the unit rate — a low unit rate with a high standing charge can cost more.
- Forgetting to switch again — the savings vanish when your discount ends.
- Ignoring exit fees or dual-fuel terms — check the small print if you’re mid-contract.
Then squeeze the rest
Once you’re on a good deal, match your tariff to your usage and stack up efficiency wins — see how to reduce your electricity bill. If you generate your own power with solar panels, a smart meter also lets you be paid for what you export.
