15 FAQs About EV Chargers in Ireland

Written by Rowan Egan | Jun 27, 2025 8:57:32 AM

As electric vehicles (EVs) become more popular across Ireland, many homeowners and drivers are considering installing home EV chargers. Whether you’re new to the world of EVs or simply trying to make the most of your setup, we’ve compiled a list of frequently asked and a few rarely asked but equally important questions about EV charging in Ireland.

Here’s everything you need to know to get plugged in.

1. Do I Need a Home EV Charger or Can I Use a 3-Pin Plug?

Technically, you can charge your EV with a standard 3-pin socket, but it's not recommended. Charging is extremely slow (often 24+ hours for a full charge) and puts significant strain on the plug, which may not be designed for constant high loads. A dedicated home charger is faster, safer, and future-proofed.

2. How Fast Will a Home EV Charger Charge My Car?

Most home chargers in Ireland are rated at 7.4 kW (single-phase). This usually adds around 30–50 km of range per hour, depending on your car’s battery. Full charges typically take 6–10 hours overnight. If your property supports three-phase electricity, faster 22 kW charging is possible with compatible EVs and chargers.

3. Can I Get a Grant for Installing an EV Charger?

Yes! The SEAI offers a grant of up to €300 for installing an EV home charger. To qualify, you must own an eligible EV and install a smart charger at your primary residence. Check the SEAI website for current criteria and approved installers.

4. Can I Install an EV Charger If I Live in an Apartment?

Yes, but it depends on your building. Apartment dwellers will typically need permission from the property management company or landlord, as chargers require access to shared electrical systems and parking spaces. Newer buildings are often pre-wired for EV infrastructure.

5. Do EV Chargers Work with Solar Panels?

Many do! Brands like Zappi integrate with solar PV systems and allow you to charge your EV using surplus solar electricity. This is a great way to reduce your reliance on grid energy and increase your use of renewables, especially on sunny days.

6. Can I Use My EV Charger During a Power Outage?

Standard EV chargers won’t operate during a power cut. However, some advanced systems (combined with solar + battery storage) can offer limited off-grid charging. It’s rare and expensive, but becoming more possible as home energy systems evolve.

7. Is It Cheaper to Charge at Home or at Public Chargers?

Home charging is almost always cheaper, especially if you’re on a smart electricity tariff or have night rate pricing. Public fast chargers are convenient, but often cost more per kWh. If you can, schedule charging during off-peak times at home to maximise savings.

8. Can I Share My Home Charger with Visitors or Neighbours?

Yes, some chargers allow access control via app, so you can share usage and even set a price if desired. This is handy if you want to offer charging to friends, neighbours, or Airbnb guests. Just make sure your electrical setup can handle the additional load.

9. What Happens If I Move House After Installing a Charger?

You can either leave it behind (as a selling feature!) or take it with you, depending on the installation and mounting style. Tethered units are harder to relocate, while untethered (socket-only) models may be easier to remove and reinstall. However, reinstallation will still require an electrician.

10. Can I Use an Extension Cable with an EV Charger?

No, it’s strongly discouraged. EV charging requires a constant, high-power current, and extension cables are not designed for this load. Using one can cause overheating or even fire. Always plug directly into your charger and follow manufacturer safety guidelines.

11. Will an EV Charger Increase My Electricity Bill Significantly?

It will increase your usage, yes. But not drastically if you're strategic. For example, charging on a night-rate or smart tariff can dramatically reduce your costs. On average, charging an EV costs 70–80% less than fuelling a petrol or diesel car.

12. Are All EV Chargers the Same?

Not at all. There are tethered vs untethered, smart vs basic, and solar-integrated vs standard models. Some work better with certain cars, and others integrate with smart home or energy systems. That’s why choosing the right installer and hardware is key.

13. Can EV Chargers Be Installed Outside?

Yes, nearly all chargers sold in Ireland are weatherproof and safe for outdoor use. However, placement still matters. Avoid spots with excessive moisture, flood risk, or where cables may become trip hazards. Your installer will assess this during a site survey.

14. Do I Need to Upgrade My Home’s Fuse Board?

In some older homes, yes. A charger draws a lot of power, so your fuse board may need upgrading, or a dedicated circuit may be required. WattCharger always performs a safety check and will let you know if upgrades are necessary before installation.

15. What’s the Most Overlooked Part of Buying a Charger?

Future-proofing. Many people only consider their current EV, but you should also think about your next car, solar compatibility, or load balancing needs. Installing a charger with smart controls or solar integration now could save you time and money later.

Final Thoughts

EV chargers are essential for convenient, cost-effective, and efficient electric driving in Ireland. Whether you’re in a detached house, semi-detached, or even a shared building, there are solutions available. And with SEAI grants, smart meter support, and solar-compatible options, it’s easier than ever to get the most from your electric vehicle.
