Cheapest Gas and Electric Suppliers in Ireland: Compare Now

If you’ve ever sat down to compare Irish energy suppliers and felt your eyes glaze over, you’re not alone. The market has shifted dramatically over the past year, with smaller challengers like Yuno Energy regularly undercutting the big players by significant margins. This piece cuts through the noise: we’ll look at what the current cheapest tariffs actually are, which providers keep their prices most consistent, and how to switch without the typical hassle.

Potential savings on switch: up to €600 · Average gas unit rate: 10.25–11.26 cents per kWh · Top comparison sites: Switcher.ie, Bonkers.ie · Key suppliers: Electric Ireland, Energia, Yuno Energy · Dual fuel focus: gas and electricity bundles

The Irish energy market shows a clear three-tier pricing structure: challengers like Waterpower and Yuno Energy lead on price, mid-tier players cluster within €82 of each other, and premium suppliers like Pinergy sit €700+ above the cheapest options.

Who is the cheapest gas and electricity supplier in Ireland?

The answer shifts regularly, but as of April 2026, Waterpower leads for customers using standard direct debit and ebill at €1491 annually for a 4200 kWh usage profile. Yuno Energy sits just €63 behind at €1554 for its 1 Year Variable Plan, with Electric Ireland close at €1558. The spread between the cheapest and most expensive—Pinergy at €2220—represents a potential annual saving of roughly €729 simply by switching.

Yuno Energy

Yuno Energy has become the most frequently cited cheapest supplier across comparison sites, offering competitive rates for both standard and smart meter customers. Their €280 welcome cashback over 12 months for new customers makes them particularly attractive for those willing to commit to a longer relationship. According to Smart Saver’s January 2026 analysis, Yuno Energy’s annual bill of €1289 for 4200 kWh represented a saving of €285 against the market average of €1574.

Electric Ireland

Electric Ireland positions itself as the second-cheapest option at €1558 for 4200 kWh in April 2026, just €4 more than Yuno Energy on the same usage profile. Their market presence and established customer service reputation make them a frequent choice for households seeking stability alongside competitive pricing. New customer deals and straightforward switching processes add to their appeal.

Energia bundles

Energia offers a dual fuel bundle that competes well on price, with their Standard Electricity plan at €1573 as of April 2026 per Switcher.ie. Their official tariff documentation shows a day unit price of 42.13c/kWh including VAT, which drops to 35.81c with their 15% online discount. The urban standing charge of €265.01 annually including VAT makes them particularly competitive for city-based households.

Who has the cheapest gas prices in Ireland?

Gas unit rates in Ireland typically range from 10.25 to 11.26 cents per kWh across providers. The actual cost you’ll pay depends heavily on your usage pattern—whether you’re using gas primarily for heating, hot water, or cooking—and which supplier you choose. Bonkers.ie provides comparison tools using your GPRN (Gas Point Registry Number) to show personalised rates based on actual consumption.

Unit rates overview

Gas pricing varies less dramatically between suppliers than electricity does, but differences still exist. Bord Gáis Energy, SSE Airtricity, and Flogas compete actively for gas customers, with promotional rates available for new switchers. The national average masks these variations, so direct comparison using your own usage figures produces more accurate results than relying on headline rates.

Supplier rankings

Bord Gáis Energy maintains strong market share in gas provision, while Flogas has emerged as a competitive alternative for both gas-only and dual fuel customers. Energia’s gas tariffs complement their electricity offerings, making dual fuel bundles particularly attractive when both fuels are sourced from the same provider. Switching between gas suppliers takes approximately five working days once your new supplier receives your application.

Heating cost impacts

For households using gas for central heating, the difference between suppliers can amount to €100–€200 annually on heating bills alone. Energy efficiency measures—better insulation, thermostat controls, and timing your heating use—compound the savings from switching suppliers. A household spending €1,400 on gas annually could save €140–€280 by moving to a cheaper provider.

Who has the cheapest rates for electricity?

Electricity rates show the most dramatic variation between Irish suppliers. Pinergy’s April 2026 rate of €2220 for 4200 kWh sits €729 above Waterpower’s €1491 for the same usage—the kind of gap that makes comparison not just worthwhile but essential. SSE Airtricity’s day rate hovers around 18c/kWh, placing them in the mid-table alongside Energia’s 42.13c/kWh day unit price before discounts.

Electricity-only tariffs

Electricity-only customers have the most flexibility since they can shop the entire market without coordinating a gas switch. Yuno Energy, Waterpower, and Electric Ireland lead on price, while Pinergy commands the premium end of the market. Smart meter customers access additional time-of-use tariffs that can significantly reduce costs for those able to shift consumption to off-peak hours.

Provider breakdowns

The eight residential electricity suppliers operating in Ireland as of April 2026 each target different customer segments. Yuno Energy and Waterpower focus on price competitiveness, Electric Ireland balances price with service reliability, and SSE Airtricity offers strong dual fuel packages. Pinergy positions itself toward customers willing to pay premium rates for perceived green credentials or flexible contract terms.

Regional variations

Northern Ireland operates as a separate market with five providers—the Consumer Council NI maintains a dedicated price comparison tool for those in the north of Ireland. Republic of Ireland customers cannot access NI-only tariffs, but the comparison methodology and switching process remain similar across both jurisdictions.

Is Airtricity cheaper than Bord Gais?

Comparing SSE Airtricity against Bord Gáis Energy requires looking at both headline rates and the specific tariff you’re eligible for. SSE Airtricity’s day rate around 18c/kWh competes directly with Bord Gáis Energy’s standard offering, but promotional rates and new customer cashback offers can swing the effective annual cost significantly. Neither consistently beats the other across all tariff types.

Direct rate comparison

SSE Airtricity offers tariffs in the 18–22c/kWh range depending on meter type and payment method, while Bord Gáis Energy competes in the same bracket for standard products. Dual fuel customers with Bord Gáis Energy often see the most benefit since the company’s strength lies in coordinated gas and electricity pricing rather than electricity alone. SSE Airtricity’s dual fuel proposition has tightened in recent years as competition in this segment has intensified.

SSE Airtricity plans

SSE Airtricity provides standard, day/night, and smart meter tariffs, with the day/night option offering roughly 30% cheaper electricity during off-peak hours. Smart meter customers on SSE Airtricity’s time-of-use tariffs can achieve meaningful savings by running high-consumption appliances during cheap periods. New customer promotions typically include a discount or cashback offer that runs for the first 12 months.

Bord Gáis Energy offers

Bord Gáis Energy’s competitive positioning centres on their established brand and straightforward switching process. Their gas and electricity bundles frequently appear in comparison site recommendations for households seeking simplicity over maximum savings. Third-place ranking in Smart Saver’s January 2026 analysis at €1345 for 4200 kWh demonstrates their price competitiveness, even if they don’t always claim the cheapest spot.

The implication: Neither supplier consistently wins on price alone—the better question is which offers the most valuable package for your specific situation, accounting for contract length, payment method discounts, and dual fuel benefits.

Bord Gáis Energy vs SSE Airtricity: which supplier is better?

The honest answer depends entirely on what “better” means for your household. If you’re prioritising absolute lowest price, smaller challengers like Yuno Energy or Waterpower typically outperform both major suppliers. If you value brand recognition, established customer service processes, and the convenience of a single company managing both gas and electricity, Bord Gáis Energy and SSE Airtricity both offer reasonable propositions.

Service quality

Both Bord Gáis Energy and SSE Airtricity field regular customer satisfaction surveys, with neither consistently outperforming the other. Complaint rates to the Commission for Regulation of Utilities (CRU) provide one objective measure—check the CRU’s published data quarterly for updated figures. Smaller suppliers sometimes report higher complaint rates simply because they handle fewer cases and have less established complaints processes.

Price stability

Bord Gáis Energy and SSE Airtricity both offer fixed-rate tariffs that lock in prices for 12 months, protecting against mid-contract price rises. Variable tariffs from either supplier track market movements, which can work in your favour during falling markets but expose you to increases during volatile periods. Yuno Energy’s 1 Year Variable Plan offers similar protection at a lower base rate.

Dual fuel options

Dual fuel bundles from both suppliers offer convenience benefits—single bill, one customer service contact, coordinated account management. The discount for bundling gas and electricity with the same supplier typically ranges from 2–5% off the combined bill. Whether this discount outweighs the savings available from choosing separate cheapest suppliers for each fuel depends on your specific usage profile and tariff eligibility.

The pattern: For most households, the mid-tier competitors cluster within €82 of each other, while outliers at either end of the market differ by over €700 annually—making it worth comparing the entire market rather than just major brands.

Five providers dominate comparison site rankings in April 2026, each offering distinct advantages depending on your payment method, meter type, and fuel preferences.

Electricity unit rates and standing charges vary significantly between suppliers, with standing charges alone accounting for €60–€72 in annual costs regardless of consumption levels.

The difference between the cheapest and most expensive unit rate suppliers can exceed €500 annually before considering standing charges or discounts.

How to switch gas and electricity supplier in Ireland

Switching energy suppliers in Ireland is straightforward, but doing it right requires following a few key steps to ensure you’re comparing like-for-like tariffs and avoiding common traps.

1. Gather your numbers. You’ll need your MPRN (Meter Point Reference Number) for electricity and GPRN for gas—found on your current bill. Note your annual consumption in kWh if available, or select a standard usage profile based on your household size.
2. Use a comparison aggregator. Visit Bonkers.ie or Switcher.ie and enter your MPRN/GPRN and usage. These tools pull current rates and calculate your annual cost based on your specific profile.
3. Check eligibility carefully. Some advertised rates apply only to new customers, direct debit payers, or those signing up for 12-month contracts. Read the tariff terms to confirm you’re actually eligible for the headline rate.
4. Calculate total cost, not just unit rate. Multiply the unit rate by your expected consumption, then add the standing charge. This gives you the true annual cost. A lower unit rate with higher standing charges may not save money for low-consumption households.
5. Submit your switch. Once you’ve chosen a supplier, the switching process completes automatically. Your new supplier handles the paperwork with your current provider. You’ll receive a final bill from your old supplier within weeks.
6. Mark your calendar. Most promotional rates run for 12 months. Set a reminder 11 months after switching to compare rates again—staying put while promotional rates expire is one of the most common ways Irish households overpay.

What’s confirmed and what’s still unclear

Based on cross-referencing multiple comparison aggregators and official tariff publications, certain facts emerge clearly. Others remain genuinely uncertain due to the dynamic nature of Irish energy pricing.

• Ireland has 8 residential electricity suppliers (April 2026) with 11 licensed in total per Bonkers.ie
• Comparison aggregators like Switcher.ie and Bonkers.ie lead the market for transparent supplier comparisons
• Waterpower holds the lowest standard rate at €1491 for 4200 kWh as of April 2026 per Switcher.ie
• Yuno Energy offers competitive €280 cashback for new customers per Smart Saver

• Exact current cheapest supplier varies by usage profile and eligibility criteria
• Most expensive supplier ranking shifts as promotional offers launch and expire
• Full dual fuel discount comparison across all 11 suppliers requires individual tariff analysis
• Exit fee terms vary by contract and supplier—specific figures not published universally

Our price comparison shows that bill reductions of as much as €600 can be made in just one year by switching to the deal from the cheapest electricity supplier.

As of April 2026, Yuno Energy offers the cheapest electricity for most Irish households, followed by Flogas and Bord Gáis Energy.

— Smart Saver (Energy Guide)

For Irish households, the choice has narrowed to a clear pattern: challengers like Yuno Energy and Waterpower consistently undercut the established suppliers on price, but the gap closes or reverses when promotional cashback offers and contract terms are factored in. The aggregator tools exist—Switcher.ie and Bonkers.ie both offer free, MPRN-based comparisons—but the savings only materialise if you actually switch and then switch again when promotional periods end.
