The Short Answer
Charging an EV at home in Ireland costs roughly €3-5 per 100km on a night rate tariff. Compare that to €10-12 per 100km for petrol, and you're looking at savings of €800-1,500 per year depending on how much you drive.
Let's break down exactly where these numbers come from.
Home Charging Costs
Electricity Rates in Ireland
The cost of charging at home depends on your electricity tariff:
- Standard rate: ~€0.30-0.35/kWh
- Night rate (smart meter): ~€0.16-0.20/kWh
- EV-specific tariffs: Some providers offer even lower night rates
With a smart meter and night rate tariff, you can charge your EV for roughly half the cost of standard rates. This is why scheduling your charger for off-peak hours makes such a difference.
Cost Per Charge
A typical EV battery is 50-70 kWh. Here's what a full charge costs:
- At night rate (€0.18/kWh): €9-13 for a full charge
- At standard rate (€0.32/kWh): €16-22 for a full charge
Most daily commuters only need to top up 20-30%, costing €2-4 per day on night rates.
Cost Per Kilometre
Using the average EV efficiency of 15 kWh per 100km:
- Night rate: €0.027/km (€2.70 per 100km)
- Standard rate: €0.048/km (€4.80 per 100km)
Compare that to a petrol car at 6L/100km and €1.70/L — that's €10.20 per 100km, roughly four times more expensive.
Home vs Public Charging
Public charging is more expensive than home charging:
- Slow public chargers (AC): €0.35-0.45/kWh
- Fast chargers (DC): €0.50-0.70/kWh
- Ultra-rapid chargers: €0.60-0.80/kWh
For a full 60 kWh charge:
- Home (night rate): ~€11
- Slow public: ~€24
- Fast public: ~€36
Home charging is 2-3x cheaper than public charging. This is the single biggest financial argument for installing a home charger.

Additional Savings You Might Not Know About
Motor Tax
EVs in Ireland pay a flat €120/year motor tax. Petrol cars typically pay €200-600/year depending on emissions. That's a saving of €80-480 per year.
Maintenance
Electric vehicles have far fewer moving parts than petrol or diesel cars. No oil changes, no exhaust systems, regenerative braking reduces brake wear. Typical EV maintenance savings: €200-400/year.
Toll Discounts
Some Irish toll roads offer discounts for electric vehicles. Check with individual toll operators for current offers.
Tips to Minimise Charging Costs
- Get a smart meter — if you don't have one, contact your electricity provider. Night rates can halve your charging costs.
- Schedule charging for off-peak hours — most smart chargers let you set this automatically. With Volt Éire's charger, you set it once in the app.
- Use the right tariff — compare EV-specific tariffs from providers like Electric Ireland, SSE Airtricity, and Bord Gáis.
- Don't charge to 100% daily — for battery health and efficiency, charging to 80% for daily driving is recommended by most EV manufacturers.
The Bottom Line
Home EV charging in Ireland costs roughly €3-5 per 100km — about a quarter of what you'd spend on petrol. A home charger pays for itself in under a year for most drivers, and saves thousands over its lifetime.
