How Irish electricity pricing works
Every Irish electricity bill has two main charges: a unit rate (charged per kWh of electricity you use) and a standing charge (a daily fixed fee regardless of how much you use). When comparing suppliers, both matter. A supplier with a low unit rate but a high standing charge might cost you more if you use a lot of electricity, and vice versa.
Unit rates vary by supplier and tariff, but typically sit in the range of 28–38 cent per kWh. Standing charges are usually 45–65 cent per day. These numbers shift as suppliers respond to wholesale market changes, so what's cheapest today may not be cheapest next year.
Why Irish electricity prices are among the highest in Europe
Ireland generates around 50% of its electricity from gas — and gas is priced on volatile international wholesale markets. When European gas prices spiked in 2022, Irish electricity prices went with them. That exposure is structural, not accidental.
Other factors: Ireland's grid is small and isolated (no interconnectors to mainland Europe), network infrastructure costs are spread across a relatively small population, and the PSO levy funds renewable energy contracts. All of these add to the unit rate you pay.
The long-term answer is more renewables — Ireland has exceptional wind resources — but building them takes time. In the meantime, reducing how much electricity you use is the most reliable way to cut your bill.
What makes up your bill
Unit rate (per kWh)
The electricity you actually consume. Typically 28–38 cent per kWh depending on your supplier and tariff.
Standing charge
A fixed daily charge — roughly 45–65 cent/day — for being connected to the grid. You pay this even if you use nothing.
PSO levy
Public Service Obligation levy — funds renewable energy support and legacy peat generation. Set annually by the CRU.
VAT
Electricity is charged at the 13.5% reduced VAT rate in Ireland. It applies to the full bill including the standing charge.
Government energy credits
The Irish government introduced electricity credits in response to the energy price crisis. For 2024/25, a total credit of €450 was applied to household electricity accounts in three instalments across the winter billing period. The credits are applied automatically by your supplier — you don't need to apply or claim anything. The amount and structure of credits changes with each Budget, so check the current position at gov.ie when planning your bills.
Gas prices in Ireland
If your home is on mains gas, your bill has the same structure as electricity — a unit rate (in cent per kWh) plus a standing charge. Gas is priced on European wholesale markets and follows the same volatility pattern as electricity: cheap in 2020, extremely expensive in 2022, and still elevated compared to pre-2021 levels.
Switching gas supplier works the same way as switching electricity — same pipes, same gas, just a different billing company. Compare using the same CRU tool at powercomparison.ie. Watch for exit fees on your current contract before moving.
If you're heating with gas and your boiler is old, it's worth looking at the heat pump route — the SEAI grant covers up to €6,500 of the switch cost. See parce.ie/heat-pumps for a full breakdown.
How to read your electricity bill
Three numbers are worth finding on every bill: your unit rate, your standing charge, and your total kWh used in the period. Everything else is either tax or noise.
Your MPRN (Meter Point Reference Number) is also on your bill — you'll need it when switching supplier. It's the unique identifier for your connection to the grid, not your supplier.

Calculate your own annual cost
Take your unit rate (in cent/kWh), multiply by your annual kWh usage, add your standing charge multiplied by 365. That's your base annual cost before VAT and the PSO levy.
(Unit rate × annual kWh) + (standing charge × 365)
e.g. (0.33 × 4,200) + (0.55 × 365) = €1,388 + €201 = €1,589/yr
When to switch
Switching is most worthwhile when your introductory rate expires — usually after 12 months. Most suppliers offer discounts to new customers that revert to a higher standard rate at the end of the first year. If you haven't switched in more than a year, you're almost certainly on an uncompetitive rate.
Switching in Ireland has no downside. Same grid, same reliability, no engineer visit, no interruption to supply. The only risk is an exit fee on your current contract — check your current terms before committing.
How to reduce your electricity bill
Compare tariffs and switch
The CRU (Commission for Regulation of Utilities) operates a price comparison tool at powercomparison.ie. Enter your usage and it shows what you'd pay with each supplier. Watch for cashback offers — they reduce the effective cost but may not show in the headline rate comparison. Also check whether introductory offers have a minimum term.
Switch to a night rate tariff
If you have storage heaters, an electric immersion, or an EV, a night rate tariff can cut costs significantly. Electricity is cheaper during off-peak hours (typically 11pm–8am). You charge storage heaters or your car overnight at the lower rate, and they release heat or provide range during the day. Ask your supplier whether a night rate is available — most offer one.
Get a smart meter
ESB Networks is rolling out smart meters across Ireland. A smart meter records your usage in 30-minute intervals, enabling time-of-use tariffs where you pay less for electricity used at off-peak times. If you haven't had a smart meter installed yet, you can request one through ESB Networks.
Use less — the real long-term answer
Switching supplier saves you money in Year 1. Actually consuming less saves you every year from here. The most effective reductions:
- Solar panels — generate your own daytime electricity. SEAI grant up to €2,400. See parce.ie/solar →
- Insulation — reduces heat loss so you spend less on heating. SEAI grants up to €8,000 for walls. See parce.ie/grants →
- Heat pump — 3–4x more efficient than an oil or gas boiler. SEAI grant up to €6,500. See parce.ie/heat-pumps →
- BER upgrade — improving your home's energy rating directly reduces consumption. See parce.ie/ber →
Common questions
What households most often ask about electricity prices and switching.
What is the average electricity bill in Ireland?▾
An average Irish household uses approximately 4,200 kWh of electricity per year — a figure SEAI publishes as a benchmark. At a typical unit rate of around 30–35 cent per kWh plus a standing charge of roughly 50 cent per day, annual bills land somewhere between €1,500 and €2,000 before any energy credits. Actual bills vary significantly by household size, how much you're at home, and whether you use electricity for heating or hot water.
How do I switch electricity provider in Ireland?▾
You contact the new supplier directly — either online or by phone — give them your MPRN (Meter Point Reference Number, found on your current bill), and they handle the transfer. There's no interruption to your electricity supply. The same wires deliver power regardless of who you're with. The switch typically completes within 2–4 weeks. Check your current contract for exit fees before switching — some introductory offers carry a penalty for leaving early.
What is the PSO levy on Irish electricity bills?▾
The Public Service Obligation (PSO) levy is a charge on every Irish electricity bill that funds public interest objectives — primarily supporting renewable energy generation (wind, solar) and the legacy peat-fired power stations. It appears as a separate line on your bill. The amount is set annually by the CRU and varies each year depending on wholesale market prices and the cost of supporting renewable contracts. In years when wholesale gas prices are high, the PSO can actually become negative, reducing your bill slightly.
Will I lose power when I switch electricity supplier?▾
No. Ireland has a single electricity grid. Switching supplier changes who sends you the bill, not who delivers the electricity. There is no interruption, no engineer visit, and no reconnection needed. The physical infrastructure — the wires, poles, and transformers — is owned and maintained by ESB Networks regardless of which supplier you choose.
How do I reduce my electricity bill in Ireland?▾
The most effective steps: switch to the cheapest available tariff (compare at powercomparison.ie, the CRU's tool), switch to a night rate if you have storage heating or an EV, and reduce the amount you consume. Consuming less is where the real gains are — insulation reduces how much heating you need, solar panels generate your own daytime electricity, and a heat pump is 3–4x more efficient than an oil boiler. SEAI grants cover a large share of the cost of all of these — see parce.ie/grants.
What are Irish gas prices doing in 2025?▾
Gas prices in Ireland track European wholesale markets. After the sharp rises following the 2022 energy crisis, wholesale gas prices came down from their peaks but remain well above pre-2021 levels. Irish suppliers adjust their tariffs in response to wholesale movements — changes typically filter through to household bills with a lag of several months. If you're on gas for heating, the same switching logic applies as for electricity: compare on powercomparison.ie and watch for exit fee clauses.
