Neither supplier needs an introduction, which is precisely the problem — this matchup is usually decided by familiarity rather than arithmetic. Electric Ireland is ESB’s retail arm and the supplier most never-switched homes are still on; SSE Airtricity, with around 460,000 electricity customers (per RTÉ, September 2025), is the big name people meet the first time they shop around. Brand size decides nothing here. At CRU typical usage — 4,200 kWh of electricity, 11,000 kWh of gas, urban standing charges, PSO and 9% VAT included — the two suppliers win different years of the same contract.
Year 1 is SSE Airtricity’s, and not narrowly. Its 30%-off electricity plan prices the year at €1,492 against Electric Ireland’s 16%-off €1,612; its fixed plan undercuts both at €1,294.70, though leaving that one early costs €100 per fuel rather than €50. Gas is a €333 gap — €1,166 vs €1,499 — and dual fuel lands €340 apart at €2,572 vs €2,912. Year 2 reverses the result where it matters most: Electric Ireland’s standard electricity rate works out at about €1,868 a year, SSE’s at roughly €2,010 by our sums, and Electric Ireland has raised prices once since October 2022 (8% electricity, 7.7% gas, from 1 July 2026) against SSE’s two rises in 2025 alone.
So we score Electric Ireland 7.2 and SSE Airtricity 7.1 — a photo finish that splits by behaviour. The household that re-shops every twelve months should take SSE’s deeper discounts and leave before the standard rate starts; the household that knows it will drift should stay near Electric Ireland’s gentler fall-back. Both are on the board in our full energy ranking, and if neither habit sounds like yours, the matcher will place you. matched.ie is not a CRU-accredited price-comparison site — the accredited list lives on cru.ie.

Year 1: SSE Airtricity wins every fuel on the board
Line the sign-up offers against each other at CRU typical usage and there is no contest. Electric Ireland’s headline electricity deal is 16% off units — €1,612 for an urban year — with a 20% smart-meter variant at €1,522. SSE Airtricity answers with 30% off at €1,492, a 30% smart plan at €1,409, and the quiet winner of the whole page: a fixed-rate plan at €1,294.70 that locks the unit rate and standing charge for twelve months. The catch on that last one is real — the exit fee doubles to €100 per fuel — but the price is SSE’s own published figure, not a projection.
The gaps widen off-peak of the argument, on gas and dual fuel. All year-1 urban EABs, checked 28 August 2026:
| Like-for-like plan | Electric Ireland | SSE Airtricity | Gap |
|---|---|---|---|
| 24-hour electricity | €1,612 (16% off) | €1,492 (30% off) | SSE, €120 |
| Fixed-rate electricity | — (not offered) | €1,295 (€100/fuel exit) | SSE only |
| Smart-meter electricity | €1,522 (20% off) | €1,409 (30% off) | SSE, €113 |
| Gas | €1,499 (10% off) | €1,166 (30% off) | SSE, €333 |
| Dual fuel | €2,912 (20% off both) | €2,572 (35% + 30%) | SSE, €340 |
Month 13 flips the table: €1,868 against €2,010
Both suppliers dump you onto their standard variable rate when the twelve months end, and that is where Electric Ireland earns its keep. Its post-July-2026 standard rate is 38.04c/kWh — about €1,868 a year urban. SSE’s is 41.13c/kWh — roughly €2,010 by our calculation. Same house, same kilowatt-hours, €142 apart for doing nothing. The cliffs tell the story more sharply than the totals:
Two honest complications. First, gas: SSE stays cheaper even at standard rates — about €1,542 against Electric Ireland’s €1,633 — so the year-2 crown is an electricity crown. Second, the two-idle-years sum is closer than the cliff suggests: €1,612 + €1,868 puts Electric Ireland at €3,480, SSE’s discount route at €3,502, and SSE’s fixed route at €3,305 — the deep year 1 buys back most of the steep year 2. What that arithmetic cannot buy back is year 3, when both households are on standard rates and the €142-a-year gap runs in Electric Ireland’s favour indefinitely. The mechanics of the cliff — and how to never pay it — are in year 1 vs year 2.
Every meter type vs published honesty
Electric Ireland’s billing case is breadth. It covers every configuration an Irish home can have — 24-hour, NightSaver, smart time-of-use, gas, dual fuel, a wholesale-linked dynamic tariff, and Smarter Pay As You Go prepay with Payzone, text and app top-ups. SSE Airtricity has no prepay plan at all: if a landlord fitted a prepay meter or you budget by topping up, this comparison is over before it starts. We rate Electric Ireland slightly ahead on billing (7.5 vs 7) and further ahead on service (7.5 vs 6.5), where SSE customers report slower complaint resolution in some cases.
SSE’s counterpunch is transparency and conditions worth knowing about. It publishes its Estimated Annual Bills on its own tariff sheets — most of the market makes you dig — which is why the year-1 figures on this page are SSE’s own numbers rather than our reconstruction. But its headline discounts require direct debit and eBilling; pay any other way and the advertised EAB is not your EAB. Electric Ireland’s discounts carry no such gate, and as ESB’s retail arm it is also the CRU-designated electricity supplier of last resort — if any supplier folds, its customers land at Electric Ireland with the lights still on.
€50 everywhere vs €50 — except where SSE is cheapest
On paper the contracts match: twelve months, then no fee to leave, with a 14-day cooling-off window on a normal switch. Electric Ireland charges €50 per fuel to break any fixed-term plan early — €100 on dual — and that is the whole schedule. SSE Airtricity charges the same €50 per fuel on its discount plans, but €100 per fuel on the fixed-rate plans, per the T&Cs we checked on 28 August 2026. So the cheapest plan in this entire comparison, SSE’s €1,294.70 fix, is also the most expensive one to walk out of: €100 for electricity alone, €200 if you ever fix both fuels.
The trap in this matchup: SSE’s fixed plan looks like the free lunch — €317 below Electric Ireland’s best electricity price, immune to mid-term rate rises. But it carries the doubled €100-per-fuel exit fee while you are in it, and the steeper €2,010 standard rate the moment you sleep past month 12 — a €716 jump, the biggest cliff on this page. Take it if you will diary month 11; avoid it if your switching record says otherwise.
100% by certificate vs green as an optional extra
SSE Airtricity leans on its green story harder than any big supplier in the market, and the disclosure is real: 100% renewable electricity in the CRU/SEM fuel-mix report, standard on every plan, backed by a parent that genuinely builds and operates wind farms on this island. Electric Ireland’s standard supply simply follows the disclosed fuel mix; going green there means paying extra for a Green plan. If the badge matters, SSE hands it to you at its cheapest price while Electric Ireland charges admission.
The caveat applies to both, so it decides nothing between them: these are Guarantee of Origin certificates, not different electrons. SSE’s 100% figure is achieved by matching its sales with certificates — the 2024 all-island fuel mix, even with those certificates counted, was 62.35% renewable — and Electric Ireland’s Green plans rest on exactly the same mechanism. Your kettle runs on the same grid either way. Rank the claim honestly and SSE’s version is better evidenced and cheaper than Electric Ireland’s, but if verified Irish community generation is the actual point, neither is the answer — that is Community Power, and the wider field is ranked in best green electricity.
The never-switched household vs the serial switcher
Electric Ireland is the right answer for the household this page will not change: the one that signs once and stays. Its standard rate is among the market’s gentler fall-backs, its one rise since October 2022 left standing charges alone, its exit fee never exceeds €50 a fuel, and it is the only supplier here with prepay. If you are on its standard rate right now, though, you are paying €256 a year over its own new-customer price — the cheapest possible fix is to re-contract where you stand, and the honest one is to price the market first via the matcher.
SSE Airtricity is for the household that treats energy like insurance — shopped annually, never renewed by default. Every one of its year-1 numbers beats Electric Ireland’s, the fixed plan adds protection no Electric Ireland customer can buy, and the green disclosure comes free. The deal expires the day you stop paying attention. One boundary to this verdict: it is strictly a two-horse race. Energia, the other big alternative, prices between these two on electricity and deserves its own arithmetic — see Electric Ireland vs Energia and Energia vs SSE Airtricity rather than treating this page as a three-way.

Choose Electric Ireland if
You know you will not re-shop at month 12 — Electric Ireland’s €1,868 standard-rate year beats SSE’s €2,010, its only rise since October 2022 came in July 2026 with standing charges left untouched, and every plan exits at €50 per fuel. Also the pick if you need prepay: Smarter Pay As You Go has no SSE equivalent.
