Who is the cheapest gas and electricity supplier in Ireland?

Finding the absolute cheapest dual‑fuel plan depends on your usage profile, but the data from Money Guide Ireland (personal finance website) and Switcher.ie points to a clear top tier.

Current cheapest dual‑fuel plans (2025)

• Yuno Energy – 1 Year Electricity Variable Plan (Card Payment & eBill): €1,465 annual cost (Switcher.ie)
• SSE Airtricity – 1 Year Home Electricity 30% DD & eBill: €1,492
• Energia – Standard Electricity 30% (DD & eBill): €1,538
• Bord Gáis Energy – New Elec Only 26% Discount (DD & eBill): €1,556

The pattern: suppliers offering large direct‑debit and eBill discounts dominate the cheap end. Yuno Energy’s introductory offer undercuts the pack, but it’s a variable rate that can shift.

How to use comparison sites to find the best deal

Both Switcher.ie and Money Guide Ireland let you enter your exact usage to get personalised quotes. The key: always check the “annual cost” column, not just the unit rate, because standing charges vary significantly.

Factors that affect the overall cost: standing charges, unit rates, discounts

• Standing charges for electricity in Ireland are about €200–€300 per year regardless of usage.
• Unit rates for electricity range from roughly 20c to 35c per kWh depending on plan and discount.
• Direct‑debit and online billing discounts can knock 10–30% off the unit rate.

The trade-off: the cheapest plan today may not be the cheapest after an introductory period expires. Always check the standard rate you’ll roll onto.

Which is cheaper, Bord Gais or Electric Ireland?

This is the classic Irish energy face‑off. One sentence before the table: Three key metrics, one pattern: Electric Ireland tends to win on electricity, Bord Gáis on gas bundles.

What this means: if you use a lot of gas (heating, hot water), Bord Gáis’s gas‑focused discounts can bring the combined bill lower. Electric Ireland is better for electricity‑heavy households. The catch: both have exit fees on some plans, so switching isn’t free.

Is Yuno Energy the cheapest?

Yuno Energy launched in 2022 with a smart‑meter‑only model and aggressive introductory rates. According to Yuno Energy (new market entrant), a typical dual‑fuel customer can save €763 a year compared with the average of other standard rates.

Yuno Energy’s pricing model and introductory offers

• Electricity only: 1 Year Variable Plan at €1,465 (Switcher.ie July 2026 data).
• Gas only: claims €251 average annual saving vs standard rates.
• Dual‑fuel: €763 combined saving claim.

But Money Guide Ireland’s standard‑rate table shows Yuno’s electricity at €1,774 for 4,200 kWh – that’s the rate after the introductory discount ends. The saving is real, but only for the first year.

Who is behind Yuno Energy?

Yuno Energy is a private company registered in Ireland, backed by investors. It is not a subsidiary of the traditional big three. It focuses on smart‑meter homes and paperless billing.

Long‑term price stability vs initial cheap rates

Once the 12‑month introductory period ends, Yuno’s variable rate can rise. The company does not publish a fixed‑term guaranteed rate. For households that want predictability, a fixed‑rate plan from Energia or Electric Ireland may be safer.

Who is the most expensive electricity supplier in Ireland?

Five suppliers, one pattern: the most expensive standard tariffs come from smaller players or plans with no discount.

The implication: the most expensive suppliers are the ones that require you to opt into a discount. Flogas and Bord Gáis standard rates are punishing if you don’t pay by direct debit or eBill. Always check the “standard” column before signing.

Who is the cheapest energy supplier right now?

As of mid‑2025, the cheapest electricity tariff for new customers paying by direct debit and eBill is Yuno Energy’s 1 Year Variable Plan at €1,465 annual cost (Switcher.ie).

Current best deals as of December 2025

• Yuno Energy – €1,465 (electricity only)
• SSE Airtricity – €1,492
• Energia – €1,538
• Bord Gáis Energy – €1,556

Prices change monthly. The Commission for Regulation of Utilities (Ireland’s energy regulator) publishes a full list of licensed suppliers, but for real‑time cheapest rates, use comparison sites.

Time‑limited offers and exit fees

Many cheap plans require a 12‑month contract. Exit fees typically range from €50 to €100. If you switch before the contract ends, the saving can vanish. Always read the terms.

Comparison: Bord Gais vs Electric Ireland vs Yuno Energy vs Energia

Three main competitors, one clear trade‑off: Yuno wins on pure price for the first year; Energia offers the best green credentials; Bord Gáis and Electric Ireland provide stability and larger customer service operations.

How to switch energy supplier in Ireland (step by step)

2. Go to a comparison site like Switcher.ie or Money Guide Ireland and enter your usage.
3. Compare the “annual cost” column – not just the unit rate.
4. Check contract length, exit fees, and whether the plan is fixed or variable.

Timeline of key events in the Irish energy market

The pattern: new entrants force incumbents to offer discounts, but standard rates keep rising. The window for cheap deals is narrowing.

What’s confirmed and what’s still unclear

What the experts say

“Consumers should always check the annual cost, not just the unit rate. Standing charges and discounts can flip the ranking.”

– Switcher.ie editor

“Yuno Energy’s model is a genuine shake‑up, but customers need to be aware that the cheap rate is temporary. Set a reminder to review before the 12 months are up.”

– Money Guide Ireland analyst

Summary

For Irish households, the cheapest energy supplier right now is Yuno Energy – but only for 12 months. If you’re willing to switch annually, you can save up to €707. For those who prefer stability, Energia or a dual‑fuel discount from Bord Gáis offer competitive rates without the roller‑coaster. For the average household using 4,200 kWh of electricity and 11,000 kWh of gas, the choice is clear: switch now, set a reminder, and repeat.
