How Much Does an EV Charger Installation Cost?

Installing a home EV charger is a half-day job for a registered electrician in most standard scenarios. The cost reflects the charger hardware, a dedicated circuit from your consumer unit, the cable run to the charger location, and the certification required by Part P Building Regulations.

What the installation involves

The charger requires a dedicated 32 or 40-amp radial circuit from the consumer unit. The cable runs from the consumer unit to the charger mounting position, typically on an external wall of the house or inside a garage. The charger is fixed, the circuit is terminated and tested, and the unit is commissioned.

Every installation ends with an Electrical Installation Certificate and a Part P notification. The certificate is required by insurance policies and by conveyancers when the property is sold.

Cable run length and what it means for cost

The length of cable between the consumer unit and the charger is the main driver of installation time. A consumer unit located directly behind the charging point on the other side of an internal wall is the simplest scenario. A run that goes up through the property, across a loft, and down an external wall adds labour. A run to a detached garage adds more still, and if that requires buried armoured cable, the groundworks add further cost.

Getting an accurate quote requires knowing the cable route. A quick description of the property layout is usually enough to produce a reliable estimate.

7kW versus 3.5kW chargers

Most homes have a single-phase supply capable of supporting a 7kW (32-amp) charger. At 7kW, the car gains roughly 25 to 30 miles of range per hour of charging, which is enough to fully charge most electric cars overnight. 3.5kW chargers are sometimes appropriate for properties with an older 60-amp service fuse where available headroom is limited. An alternative is to request a service upgrade from the Distribution Network Operator, which is free but can take several weeks.

Consumer unit capacity

The new circuit needs a spare RCBO in the consumer unit. Most modern boards have spare ways. Older fuse boards without spare capacity need to be replaced before the EV circuit can be added. If the consumer unit was already due for replacement, doing both jobs together is the efficient approach.

Smart charger functionality

Smart chargers connect to your home Wi-Fi and allow you to schedule charging for off-peak tariff windows, which can significantly reduce running costs. Some integrate with solar inverters to divert surplus solar generation into the car. Some include load balancing, which limits the EV circuit's draw when other large loads are running simultaneously.

The cost difference between a basic tethered unit and a smart charger with these features is modest relative to the potential saving on electricity bills over the charger's lifetime.

What is included in the installation price

A standard installation quote covers: charger unit, dedicated circuit from consumer unit, all cable and containment, mounting hardware, testing, Electrical Installation Certificate, and Part P notification. Groundworks for a buried cable run and any consumer unit replacement work are quoted separately where they apply.
