You can charge at home without owning the house. The wallbox is another matter: it is fixed to a wall, it draws serious power, and somebody has to own it when you leave. Here is what it costs on this coast in 2026 and what the lease should say before an electrician touches anything.
A 7 kW wallbox with a normal installation runs €800–1,600 in Spain this year. In a communal garage with a long cable run from your meter, €1,000–1,600 is the realistic band; an old fuse board, a three-phase supply or 30 metres of cable can push it past €2,000. Quotes usually include the unit, cable, protections, labour and the electrical certificate. Ask for that certificate by name, because the wallbox is a fixed installation and not a plug-in appliance.
The maths is friendly. Seven kilowatts adds roughly 40–50 km of range per hour for a car that uses 17–19 kWh per 100 km, so an overnight charge of eight hours covers 320–400 km. At €0.20–0.28 per kWh on a Spanish home tariff, 100 km costs €3.40–5.30. A public fast charger at €0.45–0.79 per kWh costs three to five times more, and the expensive part of public charging is rarely the electricity.
Spanish lease law does not have a special article for chargers. It has article 23: works that change the layout or the fixed elements need the owner's written consent. A wallbox drilled into a garage wall is a fixed element. In practice the conversation goes one of two ways. The owner installs and keeps it, which adds value to the house and usually means you pay nothing beyond the electricity. Or you install and pay, and the lease must say whether the box stays, whether it is removed at exit and who patches the wall.
In a communal garage the community cannot refuse a charging point outright under the current property law, but it can set conditions on the cable route and the meter. Since 2018 new or renovated car parks must have pre-installation for charging under the electrical code, ITC BT-52. In an old building you will still be the first person to ask. In a villa there is no community to persuade, only the owner and the supply. A 4.6 or 5.75 kW contracted supply will not carry a 7 kW charger plus air conditioning and a pool pump, so either the potencia goes up or the wallbox gets load management that throttles itself when the house is busy.
A portable charger on a normal Schuko socket gives 2.3 kW, about 10–13 km of range per hour. That is 150 km over a long night, and it heats the socket. In older Maresme houses the garage circuit is often 2.5 mm² cable on a 16 A breaker, sometimes shared with the utility room. Extension leads and adapters are how fires start. Use the slow cable for emergencies and for a plug-in hybrid, not as the permanent answer for a 90 kWh car.
Ask for the last twelve months of electricity bills before you sign. A house that already runs at 700 kWh a month with a pool and air conditioning has little headroom on a 5.75 kW supply, and the upgrade is a fixed charge that follows you for the whole lease.
The MOVES III programme closed on 31 December 2025, so anyone quoting it in a sales pitch is working from an old slide. What remains is a 15% IRPF deduction for installing a charging point, and that deduction is written for the owner of the property, which a tenant usually is not. Regional schemes come and go: Catalonia has run charging grants through ICAEN, and municipalities occasionally add their own. If the owner pays for the box, they claim; if you pay, ask a gestor before you count on anything.
Find the house first, then the electrician. A villa with a garage, a three-phase supply and space beside the meter is a one-day job. A hillside house from 1985 with a 3.5 kW supply and the meter in the kitchen is a project. Get two fixed quotes before signing the lease, put the permission, the ownership and the meter in an annex, and photograph the garage wall on the day you arrive.
Tell us the car, the daily distance and whether the house has a garage. We know which Maresme villas already have a charger, which ones have the supply for one, and which owners will not sign the annex.
