Quick Answer
Flogas pays the higher CEG rate at 18.50 c/kWh versus PrePayPower at 15.89 c/kWh. For a typical 4.4 kWp Irish solar home exporting 2,000 kWh/year, the difference is €52 per year. The cheaper rate isn't always the wrong call though, import unit rates, standing charges and contract terms can offset a small CEG gap. Always compare the total annual bill rather than the export rate alone.

Verdict: Flogas or PrePayPower?
Flogas wins on rate at 18.50 c/kWh versus PrePayPower at 15.89 c/kWh, a 2.61 c/kWh gap worth roughly €52 per year on a typical 4.4 kWp Irish system exporting 2,000 kWh. That gap is significant enough to be worth switching for, assuming import unit rates are broadly comparable.
Whichever you pick, also consider the import unit rate, standing charge, and any sign-up bonuses, CEG income is rarely the deciding factor on its own. See our full CEG rate comparison for all eleven Irish suppliers.

Can I switch suppliers without losing CEG payments?
Yes. Switching takes 2–14 days and you don't lose power. Outstanding CEG with your old supplier clears on your final bill; you re-register the microgenerator with your new supplier and CEG resumes from the next bill.
Does either supplier cap how much export it pays for?

Is the CEG payment taxable?
Under Section 216D of the Taxes Consolidation Act 1997 (as extended by Finance Act 2025 to 31 December 2028), the first €400 per year of CEG export income is exempt from income tax. Income above that is taxable.
