EV Charger Cost in 2025: What to Budget

For most homes in 2025, the all-in cost of an EV charger installation falls between £800 and £1,500 for a 7kW single-phase unit. That range covers the charger hardware, installation, and Part P certification. Several factors can push the cost higher, and a government grant can bring it down.

The main cost drivers

Cable run length is the biggest variable. The EV charger connects to your consumer unit (fuse board). If the consumer unit is in a detached garage, a basement, or on the opposite side of the house from the parking space, the cable run is longer and the installation takes more time. A straightforward run through the loft and down an external wall in a modern semi-detached house is the simplest case. A run of 20 metres or more through solid walls is at the other end of the scale.

Single-phase versus three-phase supply affects both charging speed and cost. Most domestic properties in the UK have a single-phase supply, which limits charge points to 7kW. Some older properties still have a 60-amp fuse from the grid, which would need upgrading by the Distribution Network Operator before a 7kW charger can be installed. That upgrade is free but can take several weeks to arrange.

Charger model and features vary in price. A basic tethered unit from a mainstream manufacturer costs less than a smart charger with app control, solar integration, and load balancing. Smart chargers add to the upfront cost but can meaningfully reduce running costs by automating off-peak charging.

Consumer unit condition matters. If the consumer unit lacks spare capacity for a new 40-amp circuit, it may need to be upgraded as part of the installation. That adds cost, though if the board is due for replacement anyway, combining both jobs in one visit is the efficient way to approach it.

The LEVI grant

The LEVI (Local Electric Vehicle Infrastructure) grant replaced the earlier OZEV EVHS grant. As of 2025, the grant is available for flat owners and those in rented accommodation who meet the eligibility criteria. Owner-occupiers in houses are no longer eligible for the domestic grant, but may qualify under other schemes depending on circumstances.

Check eligibility on the OZEV website before booking, as the scheme changes. An approved installer is required to access the grant.

What is included in a standard quote

A standard installation quote covers the charger unit, a dedicated 32-40 amp radial circuit from the consumer unit, all cable and containment, a weatherproof enclosure where needed, testing, and certification (an Electrical Installation Certificate and Part P notification). It does not include groundworks or significant structural alterations.

Ongoing costs

The charger itself has no ongoing maintenance costs beyond occasional firmware updates from the manufacturer. Running costs come from your electricity tariff. Charging overnight on an EV-specific off-peak tariff significantly reduces the cost per mile compared with charging at standard daytime rates.
