Installing an electric car charger for home use in the UK involves more than simply mounting a unit on the wall. A qualified installer must assess the property’s electrical supply, select suitable protective equipment, check whether load management is required and complete any necessary DNO notification or application.

Choosing a charger designed with installation in mind can nevertheless make the process more straightforward.

Homeowners commonly ask:

• How complicated will the installation be?

• Will the charger need to be dismantled during wiring?

• How long will the work take?

• Will the property need an electrical upgrade?

• Could additional work increase the installation cost?

The answers depend on the charger, cable route, consumer unit, parking location and electrical capacity of the property.

Choosing Between a 7kW and 22kW Home EV Charger

For most UK homes with a single-phase electricity supply, a 7kW home EV charger is the most practical option. It is generally sufficient for overnight charging and is compatible with the charging requirements of most electric vehicles.

An 11kW or 22kW charger normally requires a three-phase electricity supply. Before choosing one, the homeowner should confirm:

• Whether three-phase power is available

• Whether the property’s electrical supply can support the additional demand

• Whether DNO approval or a supply upgrade is required

• The maximum AC charging rate supported by the vehicle

Installing a 22kW charger does not guarantee that every vehicle will charge at 22kW. The actual charging speed is limited by the charger, the property’s electricity supply and the vehicle’s onboard AC charger.

Why Charger Design Matters During Installation

Some wall-mounted chargers require several covers or internal components to be removed before mounting and wiring can be completed. This can add handling steps during installation.

A charger designed around a separate mounting plate and removable main unit can help simplify the physical installation process. However, every charger must still be installed, tested and commissioned by a suitably qualified professional in accordance with current UK electrical and smart charging requirements.

The condition of the property also matters. Additional work may be required if the installation needs:

• A longer cable route

• Consumer unit alterations

• Additional protective equipment

• Load-management equipment

• Groundwork or wall penetration

• A supply upgrade

• DNO approval

• Landlord or freeholder permission

For this reason, installation time and labour costs should always be confirmed following a site assessment.

Injet Eco: Designed for Simpler Installation

The Injet Eco is a compact AC charger designed for residential and other suitable charging environments.

Its enclosure measures approximately 310 × 260 × 115 mm, allowing it to fit neatly on an external wall, inside a garage or in another appropriate charging location.

Depending on the selected model and configuration, available features include:

• 7kW, 11kW or 22kW charging options

• Tethered and untethered configurations

• App-based monitoring and control

• Scheduled charging

• Solar charging support

• Dynamic load management

• Wi-Fi 6 and Bluetooth connectivity

• Optional 4G connectivity

• Outdoor protection suitable for the selected installation

Specifications and protection ratings can vary between versions, so the exact product datasheet should be checked before purchase.

How the Push-to-Install Design Works

The Injet Eco uses a Push-to-Install design intended to reduce unnecessary handling during mounting and commissioning.

The installation structure is based around:

• A wall-mounted backplate

• The main charging unit

• A protective front enclosure

The installer secures the backplate in the selected location, completes the required electrical work and attaches the main charging unit in accordance with the installation manual.

This modular approach can help reduce mounting and assembly steps compared with chargers that require more extensive on-site disassembly. It may also make later maintenance or replacement more convenient.

The actual installation method, number of installers required and time spent on site will still depend on the property and the work identified during the electrical assessment. Installation should only be carried out by an appropriately qualified EV chargepoint installer.

Smart Energy Features for Everyday Home Charging

Once installed and commissioned, the Injet Eco app allows users to monitor charging and set charging schedules remotely.

For households using a fixed time-of-use electricity tariff, charging can be scheduled to take place during the supplier’s published off-peak hours. This can help reduce charging costs without requiring the charger to connect directly to the energy supplier’s tariff or app.

Depending on the installation configuration, the Eco may also support:

• Dynamic load management to help prevent the property’s supply from being overloaded

• Solar charging using available surplus generation

• Charging-current adjustment

• Remote charging control

• Charging history and energy monitoring

Customers using a tariff that requires direct vehicle or charger integration should check the energy supplier’s current compatibility list before switching.

OZEV Grants: Eligible Applicants May Receive Up to £500

From 1 April 2026, several OZEV home and workplace chargepoint grants increased from £350 to a maximum of £500 per socket.

The available schemes include grants for:

• Renters and flat owner-occupiers with private off-street parking

• Eligible households that rely on on-street parking and install an approved cross-pavement charging solution

• Residential landlords

• Eligible workplaces

• State-funded education institutions

A homeowner who owns and lives in a house with private off-street parking does not automatically qualify for a domestic OZEV grant.

The current schemes are funded until 31 March 2027, although the government may change or close them. Applicants should check the latest official OZEV chargepoint grant guidance before ordering a charger.

Checking Whether an Injet Eco Qualifies

OZEV eligibility applies to specific charger models and configurations rather than automatically covering every product made by a brand.

Before ordering an Injet Eco, ask your installer to confirm that:

• The exact model appears on the current OZEV eligible chargepoint list

• The selected configuration matches the approved listing

• The installer is OZEV-authorised for the relevant grant

• The applicant, property, parking space and vehicle meet the scheme requirements

If any of these conditions are not met, the installation may not qualify for funding.

How the OZEV Application Process Works

For renters, flat owners and residential landlords, the process generally involves the following steps:

1. Check which OZEV grant applies to you.

2. Obtain any required permission from the landlord, freeholder, property manager or local authority.

3. Contact an OZEV-authorised installer and request a quotation.

4. Confirm that the exact charger model is eligible.

5. Submit the customer application and supporting documents.

6. Wait until OZEV confirms that you are eligible.

7. Allow the installer to complete the installation.

8. The installer submits the claim and required evidence.

9. If the claim is approved, the grant is paid to the installer and reflected in the customer’s installation cost.

The charger must not be installed before OZEV confirms eligibility. The grant cannot normally be claimed retrospectively.

When searching for “EV charger installers near me,” check that the installer:

• Is appropriately qualified for EV charger installation

• Is OZEV-authorised if you intend to claim a grant

• Can confirm the eligibility of the exact charger model

• Provides a clear quotation covering hardware and installation

• Can complete any necessary DNO notification or application

• Explains whether additional electrical work may be required

Is Injet Eco Right for Your Home?

A suitable home EV charger should combine safe installation, reliable daily operation and the energy-management features required by the household.

The Injet Eco’s compact enclosure, modular Push-to-Install design, connectivity options, scheduling and optional energy-management features make it a practical option for many UK properties.

However, installation requirements vary between homes. Arrange a professional assessment before purchasing so that the installer can confirm the appropriate power rating, cable route, load-management requirements, product configuration and total installed cost.
