EV charger in Ireland: €700–€1,500 installed (7 kW single-phase, Mode 3, Type 2 connector). SEAI grant €300 (subject to scheme). Run a 32 A cable from the house to the charger location at build time — €200 saved vs retrofit. Cable €5–€10/m, total €100–€200 for a typical 10–20 m run. Most Irish self-builds install a 7 kW single-phase charger; 22 kW three-phase is faster but needs a three-phase supply (rare on rural sites). The charger should be sited near the parking space, with a clear cable run from the house consumer unit. ESB Networks is the connection authority; an electrician installs the charger.
