Home EV Charger Installation in Cornwall

A home EV charger installation typically costs £850–£1,300 all-in for a 7kW smart charger including the unit, installation, and Part P certificate. The price varies based on the charger brand, the complexity of the cable run from your consumer unit, and whether any consumer unit upgrades are needed. The OZEV grant (up to £500 from April 2026) is now only available for renters and flat owners — not homeowners in houses.

Yes, but it is slow (2.3kW = approximately 8–10 miles per hour of range) and not recommended for regular, overnight use. Standard plug sockets are not designed for continuous high-current loads over 8–12 hours. A dedicated 7kW home charger adds approximately 30 miles per hour and is specifically designed and safety-tested for regular EV charging. It also provides smart features like scheduling, solar integration, and app monitoring.

Most homes have single-phase electricity supply, which supports a maximum 7.4kW charge rate. A 7kW charger is standard and sufficient for overnight home charging. Three-phase supply (available in some rural properties and new builds) supports 22kW charging, which can fully charge most EVs in 1–2 hours. We assess your supply type during the installation survey and recommend the appropriate charger.

Yes — the Zappi charger is specifically designed to integrate with solar panels. In Eco mode, it uses all available solar surplus before drawing from the grid. In Eco+ mode, it only charges when solar surplus is detected. This can significantly reduce EV charging costs for households that generate their own solar electricity. The myenergi Hub connects Zappi with other myenergi devices (Eddi hot water diverter, Libbi battery) for whole-home energy management.

No — home EV charger installations do not require planning permission under current Permitted Development rights. The installation must comply with Part P electrical regulations and BS 7671 wiring standards, which our qualified electricians ensure as standard. All our installations include a Part P Building Regulations certificate.
