Best prepay electricity in Ireland

Prepay electricity is the one corner of the Irish energy market where the marketing and the maths point in opposite directions. Pay-as-you-go is sold as control — top up before you burn, no bills, no surprises — and the control is real. What the adverts never put beside it is the price of that control: a prepayment service charge of roughly €131–€164 a year that billed customers simply never pay, stacked on unit rates that no new-customer discount ever touches.

This page ranks the four suppliers that sell a household PAYG electricity option — Prepay Power, Pinergy, Electric Ireland and Bord Gáis Energy — by verified all-in year-1 cost at CRU typical usage (4,200 kWh): unit rate, standing charge, prepay service charge, PSO levy and 9% VAT, all in. Where a supplier publishes no all-in figure, we show a dash and say so rather than invent one; those suppliers sit below the verified pair, ordered by our editorial score. The other five suppliers we track — SSE Airtricity, Energia, Yuno, Flogas and Community Power — do not sell a household prepay electricity plan, so they are not ranked here.

The headline you should carry into every prepay decision: the cheapest verified 24-hour prepay plan costs €2,073 a year, while the cheapest verified bill-pay year-1 deal on our books costs €1,295. That is a €778 gap for the same electrons. Prepay earns its keep for spend control, failed credit checks and landlord-fitted meters — never on price. matched.ie is not a CRU-accredited comparison site; the accredited list is on cru.ie if you want a regulated comparator.

How much extra does prepay electricity cost in Ireland?

The prepay premium has three parts, and only one of them is visible on a top-up receipt. First, prepay unit rates sit at or near standard rates — Prepay Power charges 37.62c/kWh and Pinergy’s standard PAYG rate works out at about 41.8c/kWh inc VAT, against 31.95c on Electric Ireland’s discounted bill-pay deal and 24.63c on SSE’s fixed plan. Second, the standing charge still applies — €342.69 a year on Prepay Power. Third, and least visible, the prepayment service charge: a separate daily fee for the privilege of the prepay meter itself.

All figures are Estimated Annual Bills at CRU typical 4,200 kWh, urban (DG1) unless marked rural (DG2), inc 9% VAT and PSO, verified on each supplier’s own site on 28 August 2026. Figures marked * are computed from Pinergy’s published ex-VAT rate sheet (per-day charges × 365, plus 9% VAT). A dash means the supplier publishes no figure and we would not guess one. Prepay Power’s time-of-use plan beats its own 24-hour plans only if you genuinely move load past the 17:00–19:00 peak, which is billed at 46.81c.

One honest nuance: the premium is widest against year-1 teaser deals. SSE’s fixed plan reverts to roughly €2,010 at standard rates in year 2, at which point Prepay Power’s unchanging €2,106 is only about €96 dearer. Prepay plans have no discount to lose, so there is no month-13 cliff — but a bill-pay switcher who re-shops every 12 months (see year 1 vs year 2) keeps the €778 gap open indefinitely.

Prepay Power or Pinergy: which prepay specialist is better?

Prepay Power takes the top spot on price and on both fuels. Its cheapest verified all-in figure is €1,983 (time-of-use) and its realistic 24-hour figures are €2,073–€2,106, all with no teaser to expire — year 1 and year 2 are the same number. It is the only prepay specialist that also sells PAYG gas (€1,783 a year at CRU typical 11,000 kWh), it gives €20 of emergency credit against Pinergy’s €10, and its exit charge — €11.25 for each month left of the first 12, up to about €135 — at least shrinks as the year runs down. The June 2026 rise (+8.8% electricity, its first in about 3.5 years) is priced into every figure above. Full detail in our Prepay Power review.

Pinergy is the better product and the worse deal. The app is genuinely the best in Irish prepay — balance and half-hourly usage data a bill-pay customer would envy — and the 10% sign-up offer lands year 1 at €2,052, marginally under Prepay Power’s 24-hour plans. But the offer expires: year 2 is €2,220, unit rates rise another 7.6% from 14 September 2026, the exit charge is a flat €150 ex VAT (the steepest in the market), and there is no gas, so a gas-heated home keeps a second supplier anyway. Choose it for the data, eyes open, via our Pinergy review.

If you are choosing between the two specialists on price alone: Prepay Power’s keypad Classic plan at €2,073 beats Pinergy’s standard €2,220 by €147 a year, every year. Pinergy only wins the first twelve months, and only on the offer.

What about Electric Ireland and Bord Gáis pay as you go?

Both incumbents sell a PAYG option, and both sit lower in this ranking for the same reason: neither publishes an all-in Estimated Annual Bill for it, so we cannot verify what a typical year actually costs — and we will not guess. The dashes on their cards are not a bug; they are the honest answer this week.

Electric Ireland Smarter Pay As You Go runs on standard unit rates — the same 38.04c-class rates loyal bill-pay customers sit on — plus a daily PAYG meter service charge whose annual total Electric Ireland does not publish as an EAB. Top-up is by Payzone shop, text or app. Its real attraction is structural: you are already inside Ireland’s biggest supplier, so the walk back to a discounted bill-pay plan (€1,612 year 1 on the 16% deal) is short. The Electric Ireland review covers the rest of the brand.

Bord Gáis Energy Pay As You Go is the structural outlier: Bord Gáis offers PAYG on both fuels at its standard tariff, with no premium prepay rate claimed — the pitch is that prepay customers pay what standard-rate billed customers pay. Its standard electricity is dear (41.59c units after the October 2025 rise), and with no published PAYG EAB we cannot rank it on cost, but for a household that must stay on prepay and wants both fuels with one incumbent it is worth a quote. See the Bord Gáis review.

What emergency credit, friendly credit and top-up options do you get?

The nightmare scenario prepay shoppers actually worry about is the meter hitting zero at 21:00 on a Sunday. Two protections stand between you and the dark: emergency credit — a small negative balance the meter lends you, repaid from your next top-up — and friendly credit, windows during which the meter will not disconnect even at zero.

Exact friendly-credit hours vary by supplier and meter, so treat the welcome pack — not this table — as the contract. Two behavioural notes that matter more than any hours list. First, emergency and friendly credit are loans, not gifts: everything used is deducted from the next top-up, so a €20 top-up after a heavy friendly-credit weekend can vanish before the kettle boils. Second, self-disconnection is the risk bill-pay never has. Run out outside protected hours and the supply stops until you top up — no warning letter, no engage-and-negotiate process. A billed customer in difficulty has the Energy Engage Code and repayment plans between them and disconnection; a prepay customer has whatever is on the meter. If you are choosing prepay because money is tight, talk to MABS before accepting that trade.

Who should actually choose prepay electricity?

After all that, prepay still has three honest use cases — and pretending otherwise would be as dishonest as the adverts.

• You cannot pass a credit check. Prepay Power and Pinergy run no credit check and take no deposit; the meter is the guarantee. If a debt flag or thin credit history keeps refusing you bill-pay accounts, prepay is not the expensive option — it is the available one, and this ranking tells you which available option costs least.
• You need hard spend control. A top-up is spending you see; a quarterly bill is spending you discover. For a shared house, a budget under real pressure, or anyone who has been burned by a €600 winter catch-up bill after months of estimates, paying ~€150 a year for a hard ceiling can be a rational purchase — as long as you price it as a purchase.
• The landlord fitted the meter. If the prepay meter came with the tenancy, you may be choosing between prepay suppliers rather than between prepay and bill-pay. You can still switch supplier once the account is in your name, and a previous tenant’s debt does not transfer to you — though a PAYG meter can still hold an old vend or debt setting, so ask the supplier to clear it on day one. Our renters ranking covers the tenancy side.

Who should not choose prepay: anyone who can pass a credit check and simply likes the idea of control. The same discipline is available for free on bill-pay — a smart meter, an app with usage alerts, and a monthly direct debit — without the service charge, and with access to the discounted deals in our cheapest electricity ranking.

How do you leave prepay and move to bill-pay?

Prepay is a door that opens both ways, and the walk back to bill-pay is shorter than most prepay customers assume. The honest maths: moving from Prepay Power’s €2,073–€2,106 to a €1,612 discounted bill-pay deal saves roughly €460–€494 in year 1 — an exit charge of even €135 pays for itself in about four months.

• Check what leaving costs today. Prepay Power’s electricity exit is €11.25 per month left of the initial 12 (so it shrinks every month); Pinergy’s is a flat €150 ex VAT. Past the initial term, leaving is free.
• Check whose meter it is. Renting with a landlord-fitted prepay meter? You need the landlord’s go-ahead to change the metering arrangement — switching supplier is your right, changing the meter type may not be.
• Pick the bill-pay deal first. Start from our cheapest electricity ranking and check the year-2 figure, not just the teaser.
• Sign up with the new supplier and let them drive. You need your MPRN (11 digits, starts with 10) and a meter reading; the new supplier handles the switch with the market registration system. Supply never cuts. The steps live in how to switch energy supplier.
• Use up or reclaim your balance. Run the credit down before the switch date, and ask the old supplier how any remaining balance and the final vend are settled.
• Remember the 14-day cooling-off. Signed up and regretted it? The new contract can be cancelled free within 14 days (30 on some doorstep sales).
