EV Charging for Home - FAQs
Learn how you can charge your electric car from the comfort of your home
Simply enquire here and our installation team will give you a call to talk through your needs and options.
Smart home batteries could help with the cost by charging when electricity is at its cheapest, meaning you never pay peak prices for your electricity. Another option is solar panels, which can generate free green electricity for car charging or any other use in the home.
During installation, an electrician will check the wiring in your home, including the fuse board, main bonding, and earth conductor. We need to make sure all of these elements conform with the latest national wiring rules before installing a home charger.
Our installation team can help you with this, but it’s essential you get the paperwork for the grant completed before they visit. Visit the SEAI website for more information about getting started.
The electrician completing the work has to sign off on your paperwork for you to receive the grant from the SEAI.
Unfortunately, car charging points cannot be installed roadside due to planning restrictions. However, if this is your only option you should contact the council for a view. If you live on a private estate, then contact the management of the estate to see if they will allow charging points in the parking area.
The electric vehicle charging point will usually supply electricity to your car at a rate of 7.5kWh, while most houses have a capacity of about 14kWh.
This means you’ll likely have no problem charging at nighttime when very little electricity is being used in the home. However, it could cause issues during the day when other electric devices like electric showers, kettles, TVs, computers, ovens, and washing machines could all require power.
That’s why it’s advisable to install a load manager. This allows the electricity load being used inside the house to come first, and the remaining electricity available to go into the car. It means that your new EV car charger won’t cause you problems with your electricity supply into the home, and there is no risk of tripping fuses or causing temporary power outages.
Again, it depends.
If it’s your first EV charging point, you should qualify for a Sustainable Energy Authority of Ireland (SEAI) grant. However, you may need to upgrade your current supply system to allow car charging to operate alongside other electricity needs inside the house.
Don’t worry, all our installations are carried out by qualified electricians who will assess what you need and give you expert advice on the next steps. We have more information on these upgrades below.
It is possible to install low-energy EV chargers without making any changes to your supply, but the downside is that they take twice as long to charge an EV. That means they’re really only suitable for drivers who undertake short journeys. If you live in a rural area, you might need more powerful charging capacity to give you longer range.
If you already have a charging point at home, you cannot get a grant for a second one from the SEAI. However, installing any charging point will usually make adding a second charger cheaper.
This depends on the size of your car’s battery and your electricity tariff. A small electric car typically has a battery of around 60kW, so you can work out the cost of charging it from flat by multiplying it by the kWh rate from your electricity supplier.
With a reduced night-time EV tariff, you can charge your car at the cheapest rate and save a significant amount on the cost.
With rising fuel prices, whatever time you charge your EV you’ll still pay a fraction of the cost of filling up a petrol or diesel alternative.
