Compare Electricity Rates: Cheapest Ireland Providers
Irish households are routinely overpaying for electricity — many haven’t reviewed their tariff in years while 11 suppliers now compete fiercely for custom. The cheapest standard bill-pay plan as of April 2026 costs €1,491/year; the cheapest prepaid alternative runs roughly €362 more. This gap is the entire argument for switching.

Who has the cheapest electricity rates in Ireland?
When it comes to standard bill-pay electricity, the market leader as of April 2026 is Waterpower, offering an annual cost of €1,491 for customers paying by direct debit and e-billing (Switcher.ie comparison platform). This figure is based on an average household consumption of 4,200 kWh per year — the industry standard used across Irish comparison platforms (MoneyGuideIreland.com financial guide).
Current top providers
Several suppliers cluster tightly below the €1,600 mark for standard variable plans. Energia’s Standard Electricity 30% discount plan costs €1,538 annually, while Yuno Energy’s 1-Year Variable Plan comes in at €1,554 (Switcher.ie comparison platform). Bord Gáis Energy’s New Elec Only 25% Discount plan sits at €1,574 per year. The spread between the cheapest and fifth-cheapest is roughly €83 — significant enough to justify comparison shopping.
Bonkers.ie (CRU accredited for precision using smart meter data) and Switcher.ie dominate the comparison space, offering tools that filter by payment method, discount type, and contract length (Bonkers.ie CRU-accredited comparison tool, Switcher.ie comparison platform). Kilowatt.ie provides a tariff-only listing excluding prepaid options, while Power to Switch positions itself as an impartial comparison service covering all Irish suppliers (PowerToSwitch.ie impartial comparison service).
Factors affecting rates
Electricity costs depend on three variables: unit rate (price per kWh), standing charge, and meter type (standard, day/night, or smart) (WeSwitchU.ie switching guide). Discounted “introductory” tariffs often last 12 months before reverting to standard rates — a detail comparison shoppers should verify before signing. No single provider wins across all usage profiles, which is why independent aggregators exist to surface the best fit for individual consumption patterns.
Who is the most expensive electricity provider in Ireland?
Electric Ireland frequently appears at the higher end of standard tariffs, particularly for customers on non-discounted plans (WeSwitchU.ie switching guide). This isn’t necessarily a flaw — Electric Ireland serves a substantial portion of the market and offers Smart PAYG options — but for cost-conscious households, the published standard rates can be misleading if not compared against discounted equivalents.
Highest unit rates
Prepaid electricity providers generally carry higher unit rates than bill-pay counterparts. Pinergy, one of two companies specializing exclusively in prepaid electricity alongside PrepayPower, charges a basic unit rate of 33.97 cent before VAT with an annual standing charge of €410, bringing the estimated annual cost to €2,044 for 4,200 kWh usage (MoneyGuideIreland.com financial guide). This compares unfavorably to Waterpower’s €1,491 — a difference of €553 per year.
Avoidance tips
Standard (non-discounted) tariffs from any major supplier typically run 20–40% higher than their discount equivalents. The fix is straightforward: use a comparison tool every 12 months, or when a discount tariff expires. Bonkers.ie and Switcher.ie both allow filtering by “discounted only” to surface only active offers. For households currently on a standard tariff with any provider, switching to a discounted plan within the same supplier can yield immediate savings without requiring a meter change.
Which is the cheapest prepaid electricity in Ireland?
PrepayPower holds the title of cheapest pay-as-you-go electricity supplier, with an estimated annual bill of €1,853.06 including VAT as of March 2026 (Selectra.ie energy comparison site). This figure reflects a unit rate of 30.84 cent before VAT and an annual service charge of €435 (MoneyGuideIreland.com financial guide). The prepayment service charge itself runs at 45.04 cent per day, a cost unique to PAYG customers (PrepayPower.ie official pricing page).
Pay as you go options
PAYG electricity includes an extra Prepayment Service Charge that bill-pay customers don’t pay, making prepay inherently more expensive per unit of energy consumed (Selectra.ie energy comparison site). Main PAYG providers are PrepayPower, Pinergy, Electric Ireland, and Bord Gáis Energy (Selectra.ie energy comparison site). Smart PAYG options are available from Bord Gáis Energy, Electric Ireland, Pinergy, and PrepayPower, offering more flexible top-up mechanisms than traditional coin-operated meters (Switcher.ie prepaid guide).
Top PAYG suppliers
Two companies specialize exclusively in prepaid electricity: PrepayPower and Pinergy, both installing meters at no upfront fee (MoneyGuideIreland.com financial guide). For households facing financial hardship, five additional suppliers — Bord Gáis Energy, Electric Ireland, Energia, Flogas, and SSE Airtricity — offer PAYG with free meter installation (MoneyGuideIreland.com financial guide). Other suppliers charge at least €100 for prepay meter installation if hardship criteria aren’t met.
Who is the cheapest electricity supplier right now?
The honest answer is that “cheapest” depends on your payment method, meter type, and whether you’re willing to commit to a discount tariff. As of April 2026, Waterpower holds the lowest position for standard variable plans at €1,491/year (Switcher.ie comparison platform). Yuno Energy and Bonkers-affiliated plans compete closely, with Yuno’s 1-Year Variable Plan at €1,554 annually — notably competitive for a fixed-term product that offers billing predictability.
Live rankings
Switcher.ie maintains what amounts to a live leaderboard of electricity tariffs, updated regularly to reflect market changes (Switcher.ie comparison platform). Bonkers.ie adds a layer of credibility through CRU accreditation, using smart meter data to generate personalized savings estimates rather than relying solely on average-consumption benchmarks (Bonkers.ie CRU-accredited comparison tool). Power to Switch covers the full Irish supplier landscape impartially, without commercial relationships that could bias recommendations (PowerToSwitch.ie impartial comparison service).
Regional variations like Dublin
Unit rates and standing charges don’t vary by geography within the Republic of Ireland — the national grid means all customers pay the same network charges regardless of location (Switcher.ie comparison platform). What does vary is discount availability and local customer support presence. Dublin-based customers may find more provider options for smart meter installation, but the price comparison process remains identical to rural areas. Northern Ireland operates as a separate market with only 6 licensed providers — significantly fewer than Ireland’s 11 — with the Consumer Council providing an official comparison tool that excludes promotional offers (ConsumerCouncil.org.uk official comparison tool).
Who is the cheapest of the Big Six energy suppliers?
The “Big Six” label is a UK market construct — it refers to the six large suppliers that dominated Britain’s gas and electricity market before deregulation. Ireland’s market operates differently: there are 11 licensed electricity suppliers with no equivalent “Big Six” grouping (Bonkers.ie licensed supplier count). If you’re looking for the cheapest option among Ireland’s largest providers, however, the contenders are Electric Ireland, Bord Gáis Energy, SSE Airtricity, Energia, Flogas, and PrepayPower.
Big Six breakdown
Among these six, the April 2026 data shows Energia (€1,538/year) and Bord Gáis Energy (€1,574/year) offering competitive discounted rates, while Electric Ireland’s non-discounted standard tariffs typically run higher (Switcher.ie comparison platform). SSE Airtricity and Flogas occupy middle positions, though exact figures depend on available promotions at any given time. PrepayPower appears in this group only because of its market presence, but its prepaid model makes direct price comparison with bill-pay suppliers misleading.
2026 projections
Electricity prices in Ireland have been subject to regulatory scrutiny, with the Commission for Regulation of Utilities (CRU) overseeing market fairness (Bonkers.ie licensed supplier count). No major structural changes are expected in 2026, but discounted introductory tariffs routinely expire and revert to standard rates — a mechanism that drives “bill shock” for customers who haven’t reviewed their plan recently. The practical implication for 2026: whichever large provider you choose, the discount duration and post-discount rate matter as much as the headline price.
The table below summarizes the cost picture for the most relevant plans across both bill-pay and prepaid categories based on 4,200 kWh annual usage.
| Supplier | Plan type | Annual cost (4,200 kWh) | Key feature |
|---|---|---|---|
| Waterpower | Standard (DD & eBill) | €1,491 | Cheapest standard plan |
| Energia | 30% Discount (DD & eBill) | €1,538 | Low discounted rate |
| Yuno Energy | 1-Year Variable (Card & eBill) | €1,554 | Fixed-term predictability |
| Bord Gáis Energy | 25% Discount (DD & eBill) | €1,574 | Dual fuel available |
| PrepayPower | PAYG (Smarter Prepay) | €1,853–€1,937 | Cheapest prepaid option |
| Pinergy | PAYG (Basic) | €2,044 | Prepaid specialist |
The spread between the cheapest bill-pay plan and the most expensive prepaid option amounts to €553 per year for identical usage — a premium worth understanding before committing to any meter type.
Pinergy charges roughly €553 more annually than Waterpower for the same 4,200 kWh of consumption — a premium driven primarily by higher unit rates and standing charges baked into the PAYG model.
The next table details the rate components for the two dedicated prepaid suppliers alongside a representative bill-pay option for comparison.
| Provider | Unit rate (cent/kWh) | Standing charge | Prepayment service charge |
|---|---|---|---|
| PrepayPower | 30.84 (pre-VAT) | €435/year | 45.04 cent/day |
| Pinergy | 33.97 (pre-VAT) | €410/year | Included in standing |
| Waterpower | Varies by tariff | Varies | N/A (bill-pay only) |
| Bord Gáis Energy | Varies by tariff | Varies | Available for hardship |
| Electric Ireland | Varies by tariff | Varies | Smart PAYG option |

Frequently asked questions
How do I compare electricity rates online?
Visit an accredited comparison tool like Bonkers.ie (CRU accredited) or Switcher.ie, enter your estimated annual consumption (the industry standard is 4,200 kWh), and filter by payment method. Both platforms allow you to compare all 11 licensed Irish suppliers in one view, including current discounted rates and standing charges.
What affects electricity rates in Ireland?
Three variables determine your annual bill: unit rate (price per kWh), standing charge, and meter type (standard, day/night, or smart). Discount duration also matters — introductory tariffs typically last 12 months before reverting to standard (higher) rates.
Are there fixed rate electricity plans?
Yes. Yuno Energy and some other suppliers offer fixed-term plans that lock in your unit rate for a set period, typically 12 months. These provide billing predictability but may not always be the cheapest option if market prices drop during the contract term.
How to switch electricity suppliers?
Use a comparison site to identify the best current rate, apply directly through the supplier’s website (or via the comparison platform), and provide your MPRN (Meter Point Reference Number). The switch is handled administratively — there’s no physical visit required for standard meters, and it’s free in most cases.
What are dual fuel discounts?
Dual fuel plans bundle electricity and gas from the same supplier, often offering a combined discount of up to €391 annually versus separate contracts. Switcher.ie and Bord Gáis Energy are prominent dual fuel providers in Ireland.
Is prepaid electricity cheaper?
No. Prepaid electricity includes a Prepayment Service Charge that bill-pay customers don’t pay, making PAYG inherently more expensive per unit. The cheapest bill-pay plan (€1,491/year) costs roughly €362 less annually than the cheapest PAYG option (€1,853/year) for identical usage.
