Best dual fuel deals in Ireland

Dual fuel is the tidiest product in Irish energy: one supplier, one app, one direct debit covering both your electricity and your gas. Seven of the nine suppliers we track will sell it to you — Electric Ireland, Bord Gáis Energy, SSE Airtricity, Energia, Yuno, Flogas and Prepay Power. The other two cannot: Pinergy and Community Power sell electricity only, so there is no bundle to buy.

Tidy is not the same as cheap. On the verified figures we pulled from the suppliers' own sites on 28 August 2026, the cheapest dual bundle — SSE Airtricity at €2,572 for year one at CRU typical usage — is still about €111 dearer than the cheapest pairing of separate electricity and gas contracts. This page ranks every bundle on its combined year-1 estimated annual bill, shows the year-2 figure beside it, and runs the two-supplier maths openly so you can see exactly what the convenience costs. matched.ie is not a CRU-accredited price-comparison site — for the accredited comparators, see the list on cru.ie.

How did we rank these dual fuel deals?

The order is set by one number: the verified combined year-1 estimated annual bill (EAB) at CRU typical usage — 4,200 kWh of electricity plus 11,000 kWh of gas, urban standing charges, with PSO levy, carbon tax and 9% VAT included. Where the supplier publishes a combined dual EAB we use it; Yuno prints its dual deal as two per-fuel cards, so its figure is our sum of the two. Every euro amount was checked on the supplier's own site on 28 August 2026.

Two dual-fuel sellers cannot be priced that way, so they rank last with a dash rather than a guessed number. Energia sells a 26% dual bundle but does not publish a single combined EAB, and the bundle's rates differ from its standalone plans, so we print no figure rather than invent one. Prepay Power will happily put both fuels on one app, but as two pay-as-you-go tariffs — there is no discounted dual bundle to rank. Its two published per-fuel EABs sum to €3,889 a year, which we show for context, not as a bundle price.

And the excluded two, so the omission is not silent: Pinergy and Community Power are electricity-only suppliers. If you are with either and want one bill for both fuels, you have to leave — or, as we argue below, keep them for electricity and shop gas separately, which is often the better sum anyway.

Is dual fuel actually cheaper than two suppliers?

This is the question the whole page hangs on, so here is the working. Take the cheapest verified single-fuel contracts in our dataset this week: SSE's 1 Year Fixed electricity at €1,295 and SSE's 30%-off gas at €1,166. Run them as two separate contracts and year one costs €2,461. Now put every dual bundle beside that pair — the differences are our arithmetic on the suppliers' published figures:

Three honest readings of that table. First, no dual bundle beats the cheapest pair this week — splitting saves €111 to €508 in year one, and the Energia-plus-SSE pairing is also the cheapest year-2 line on the whole page at €3,330. Second, dual fuel is not always the dear option either: SSE's bundle carries a deeper electricity discount (35%) than its own standalone plan (30%), so the bundle at €2,572 actually beats a plain SSE 24-hour electricity + gas pairing at €2,658. Third, the pairs have small print of their own — the fixed electricity plan carries a €100 exit fee, and the Energia Smart Data plan only hits €1,382 if you can shift load off the 17:00–19:00 peak. The saving is real, but so are the conditions.

Which dual fuel deal is cheapest in 2026?

1. SSE Airtricity — €2,572 year 1. The cheapest verified bundle, and the only one whose dual discount is deeper than its single-fuel deals: 35% off electricity units and 30% off gas for 12 months, with direct debit and eBilling required. The catch is the landing: year 2 at standard rates is €3,552, a jump of about €980. Exit is €50 per fuel.

2. Yuno — €2,746 year 1. The cheapest rate card Yuno prints, and our figure is the sum of its two published per-fuel EABs (€1,554 electricity + €1,192 gas). Three conditions: the electricity side needs a smart meter (a one-way move), the gas side needs a credit meter, and every rate is variable — Yuno raised prices mid-contract in July 2026 with notice. The exit fee is €100 per fuel, the dearest here.

3. Bord Gáis Energy — €2,867 year 1. A smart-meter bundle (22% off electricity, 21% off gas) with one flat all-day rate and no peak premium — unusual among smart plans. Bord Gáis also runs a 5% loyalty discount on its single-fuel discount plans after year one, softening the cliff; its published standard dual EAB is €3,510.

4. Electric Ireland — €2,912 year 1. 20% off both fuels on a plain 24-hour meter, plus a €135 welcome bonus we deliberately leave out of the EAB (it is a one-off, not a rate). Its quiet strength is year 2: €3,501 is the least bad standard landing of the five verified bundles, because Electric Ireland's standard rates are among the lower ones.

5. Flogas — €2,969 year 1. 28% off both fuels — but the bundle is exactly its two single-fuel discounts added together, with no extra dual saving, and the year-2 figure of €3,878 is the worst on the page. Flogas's gas-only deal at €1,314 is genuinely competitive; the electricity side is what drags the bundle down.

6. Energia — no verified figure. The 26% bundle exists and Energia advertises average savings of about €760 a year, but it publishes no combined dual EAB and the bundle's rates differ from the standalone plans we could verify, so this row gets a dash, not a guess.

7. Prepay Power — no bundle. Both fuels, one app, but at standard PAYG rates with per-fuel service charges — the two published EABs sum to €3,889 with no year-1 discount at all. Choose it for top-up control, never for bundle value.

Does the dual discount survive into year 2?

No. All five verified bundles are 12-month discounts, and every one lands on standard rates at month 13 — the only cushion is Bord Gáis's 5% loyalty discount, which applies to its discount plans after year one. Here is each bundle's year-1 EAB against its year-2 landing, drawn to the same scale:

Notice how the ranking almost inverts. SSE goes from cheapest year 1 to mid-pack year 2; Electric Ireland, fourth on the teaser, has the gentlest landing at €3,501; the five year-2 totals cluster within €377 of each other while the year-1 totals spread across €397. In other words, the dual discount is a 12-month event on both fuels at once, which makes the month-11 diary reminder twice as valuable here as on a single-fuel plan. The mechanics of the cliff — and what to do at month 11 — are in year 1 vs year 2 energy prices.

Do exit fees double on dual fuel?

Yes — this is the trap the bundle brochure never leads with. Exit fees are charged per fuel, and a dual contract is two fuels, so leaving a bundle mid-term means paying twice. The per-fuel figures below are from each supplier's current terms, checked 28 August 2026:

The doubled fee changes the mid-contract maths. A €100 saving elsewhere is not worth chasing five months into a bundle that costs €100 to leave — but €200 into month 13, when the fee is zero and you are on standard rates, absolutely is. It also cuts the other way when only one fuel has gone bad value: most suppliers will let you switch a single fuel out of a dual account, paying one fee, not two. None of this applies inside the 14-day cooling-off window, when leaving is free.

Is one direct debit actually worth anything?

Honestly weighed: yes, a little — and for some households more than the spreadsheet shows. One supplier means one app, one bill to read, one set of credentials, one customer-service queue when something goes wrong, and one switch to manage every 12 months instead of two staggered contract anniversaries. If a €100–€300 annual difference is what it costs to be certain you will actually re-shop on time — rather than letting one of two separate contracts silently roll onto standard rates — the bundle can be the rational pick. A forgotten single fuel on a standard rate can burn through the two-supplier saving in a few months.

But price the convenience before you buy it. A quick checklist:

• Add up the bundle's combined year-1 EAB — the table above, or the supplier's own plan card at CRU typical usage.
• Add up the best separate pair from cheapest electricity and cheapest gas — this week that pair is €2,461.
• Compare both year-2 totals too — the bundle you can forget about is the one whose landing matters most.
• Count the exit fees: two fuels, two fees, and Yuno's €200 is quadruple the €50 singles elsewhere.
• Decide who manages the diary. One supplier, one month-11 reminder; two suppliers, two.

If the sums land close, take the bundle and enjoy the single bill. If they are hundreds apart, two suppliers and two direct debits is a small price for the difference — the switching itself is genuinely easy either way, as how to switch energy supplier walks through. Supply never cuts, and the new supplier does the paperwork for both fuels.

Do rural homes pay more for dual fuel?

Yes, and the premium comes entirely from the electricity half of the bundle. Rural (DG2) electricity standing charges are higher than urban (DG1) because ESB Networks charges more to serve rural connections; gas standing charges on the cards we checked are the same everywhere the network reaches. Only two suppliers publish rural dual EABs: SSE's bundle is €2,639 rural against €2,572 urban in year one — €67 more — and Yuno's is €2,811 against €2,746, a €65 gap. Electric Ireland does not print a rural dual figure, but its electricity plans show the same pattern: the DG2 standing charge is €314.98 against €250.76 urban, about €64 a year.

Two practical notes for rural readers. The rural premium is a standing charge, so no discount touches it — the new-customer percentage comes off unit rates, and the €65-odd gap survives into year 2 unchanged. And the deeper caveat: a rural home is also less likely to have piped gas at all. If your GPRN does not exist because the network does not reach you, dual fuel is moot — you are an electricity-only shopper, and the flagship ranking is the better page.
