How to Switch Energy Supplier in Ireland: A Complete 2026 Guide
Energy bills in Ireland remain high, but switching your electricity or gas supplier is one of the easiest ways to cut costs. If you haven’t switched in the last 12 months, chances are you’re paying more than you need to.

When is the best time to switch?
The best time to switch is before your contract ends so you avoid rolling onto expensive out-of-contract rates. If you’re already out of contract, you can switch immediately.
What you need to switch
You only need a few details from a recent bill:
- MPRN (electricity) – 11 digits
- GPRN (gas) – 7 digits
- Your estimated annual usage (kWh)
