Charging an electric car at home in Ireland: costs, night rates and grants

For most Irish EV drivers the car is now the biggest single electricity user in the house, bigger than the immersion or the tumble dryer. That makes the tariff you charge on matter more than the car’s efficiency. This autumn’s round of price increases hit night and EV rates hardest at some suppliers, so if you signed up to an EV plan a year ago, the sums have changed.

Home charging vs petrol, per 100 km

Per 100 km is the fairest way to compare, ideally with your own numbers. Here is a worked example with two stated assumptions: an electric car using 17 kWh per 100 km (a middling family EV in mixed driving) and a petrol car using 6 litres per 100 km.

The electricity rates are Electric Ireland’s published EV Night Boost prices including VAT and a 5.5% discount. The petrol price is the EU Weekly Oil Bulletin national average. Two lessons stand out. Charging at home at night costs a fraction of petrol. Charging only on public rapid chargers can cost more than petrol.

EV plans after the October increases

Most suppliers now sell a plan with a cheap window for car charging, usually a few hours after 02:00. Electric Ireland’s boost window runs 02:00 to 04:00. Energia’s Smart Drive plan lists an EV rate of 9.42c per kWh from 2am to 6am. But Energia raises prices on 12 October, and Daragh Cassidy of bonkers.ie told RTÉ that its night rates rise 28%, the EV Smart Drive rate by 30%, Smart Drive Plus by 20% and EV standing charges by 28%. Check your supplier’s letter for the new figures rather than relying on last year’s.

What to look at when you compare an EV plan:

• the length of the cheap window (two hours may not refill a large battery from a 7 kW charger);
• the day rate, which you pay for everything else in the house;
• the standing charge, which on some EV plans is higher;
• whether you need a smart meter (you do for all of these).

Our compare page lets you check plans against your actual usage, including the car. A 15,000 km year at 17 kWh per 100 km adds about 2,550 kWh, which can take a house from average to well above it.

Dynamic tariffs

Since June 2026 dynamic price tariffs, with 48 half-hourly prices published the day before, have been available in Ireland. The CRU describes the cheapest periods as typically overnight. An EV with scheduled charging is exactly the kind of flexible load these plans reward, but the price is not fixed and a still, cold evening can be expensive. They suit drivers who check the app and let the car decide when to charge.

The home charger grant

SEAI’s home charger grant is €300 in 2026, half the €600 it was until January 2024. The conditions, as summarised by installer GES in February: you own the home, it has off-street parking and an MPRN, it has not had an SEAI charger grant before, the charger is on SEAI’s Smart Charger Register and a Safe Electric registered contractor installs it. You do not need to own an EV to apply. Do not start the installation before your Letter of Offer arrives, or the claim will be refused, and you then have 6 months from the letter to finish. Apartments have a separate grant with its own conditions. A 7 kW single-phase charger is the usual choice for an Irish house. We could not confirm a typical installed price from an official source, so get two quotes.

Buying the car: grant and VRT in 2026

The SEAI purchase grant for a new battery electric car stays at up to €3,500. Minister Darragh O’Brien announced a change to the price cap: for applications received after 31 July 2026, only cars priced up to €50,000 qualify, down from €60,000. If you are also scrapping an older petrol or diesel car, Wattcharger notes that the ICE2EV scrappage scheme can bring combined support to €8,500 on a battery electric car under €50,000; check the current terms with SEAI before relying on it. Budget 2026 extended VRT relief of up to €5,000 on electric cars until 31 December 2026. Whether that relief continues into 2027 is a Budget 2027 decision, due on 6 October 2026.

Public charging prices

ESB ecars, the largest network, has raised prices by up to 6c per kWh, according to The Irish Times. In the Republic, pay-as-you-go now costs 60c per kWh on chargers up to 50 kW and 72c per kWh above 50 kW. A membership at €4.79 a month (12-month commitment) lowers this to 55c and 67c. Contactless costs 61c and 73c.

The Irish Times compared other networks on 2 September: Applegreen at 68c, Circle K at 69c, Tesla Superchargers at 57c to 64c for non-Tesla drivers, and Ionity between 46c and 81c depending on subscription. Some networks add an access fee per session. For long trips, the membership plans pay off quickly; for a driver who charges at home, pay as you go is usually enough.

Solar and the car

Daytime solar output and overnight charging do not overlap well, so panels alone rarely charge an Irish commuter’s car. Where they do help is for people at home during the day, or with a charger that can divert surplus. If you are considering both, run the solar calculator and read our solar guide before signing either contract.

What to do now

If your EV plan’s rates change in October, compare before the new prices start. Set the car to charge inside the cheapest window rather than when you plug in. And if your fixed EV plan ends next year, a contract alert will remind you before it rolls over.
