OZEV-approved 7kW home EV charger installation.

What's included

• OZEV-approved 7kW single-phase smart charger from a compliant manufacturer (Ohme, Zappi, Hypervolt, Wallbox, Andersen and others - I'll spec against your use case)
• Dedicated 32A radial circuit from the consumer unit to the charger position, in single-core Twin & Earth or SWA depending on route
• Type A RCD as minimum, Type B if the vehicle requires it (some Nissan, Renault and older EV models). Some chargers integrate the Type A/B protection internally and remove the need for external RCD selection.
• Load-management setup where the property supply is 60A rather than 100A (common on older Canterbury properties). Load-management devices (e.g. Zappi Eddi, Ohme Pro, Myenergi Harvi) allow the charger to throttle to whatever headroom the supply has, protecting the main fuse.
• DNO notification to UK Power Networks - G99 pre-notify on any domestic install of an EV charger where the property has other significant load, G98 post-notify on standalone installations
• Smart-charger compliance under the EV Smart Charge Points Regs 2021 - off-peak default charging window, randomised delay, security requirements. All compliant chargers ship with this configured.
• Building Regulations compliance certificate under Part P self-certified within a fortnight
• Registration on the OZEV grant scheme where applicable

The OZEV grant, 2026 status

The original OZEV Electric Vehicle Homecharge Scheme (EVHS) closed to new homeowner applications in April 2022. Since then the grant is restricted to:

• Renters and flat-owners in properties where the person applying does not own the freehold. £350 off the install.
• Landlords for a chargepoint fitted at a rented property. Up to 200 chargepoints per financial year.
• Fleet and workplace installs (WCS is the relevant scheme, not EVHS).

Homeowners with off-street parking who own the freehold do not currently qualify for grant. If you sit inside one of the eligible categories I file the OZEV paperwork as part of the job.

Canterbury-specific notes

Victorian terraces with no driveway. An EV charger install is not viable without off-street parking - even if you could route the cable to the pavement, the OZEV compliance and the DNO both require the charge point to be on private land, not overhanging the highway. Some Canterbury terraces on Wincheap and St Dunstan's have small rear driveways or side alleys off-street where an install is possible.

Hales Place, Thanington, new-build Thanington Park. Straightforward installs - usually side-wall route from the consumer unit under the eaves to the charger position at the front-parking bay.

CT4 village properties. Longer cable runs, sometimes 20–30m from the internal sub-main to the charger, so cable-sizing calculation matters. Voltage drop across the run needs to stay inside 5% at full 32A load.

Listed properties. The charger itself, and any surface cable route across a listed elevation, needs Listed Building Consent. Canterbury City Council are generally supportive of EV charging installs on listed properties provided the fittings are unobtrusive (dark colour, low-profile unit, cable route via a rear elevation not the front face).

Frequently asked

Do I need a special charger for my car?

For a UK 7kW home charge, no. Any Type 2 socket charger from an OZEV-approved manufacturer will charge every current EV sold in the UK. The Type A vs Type B RCD choice depends on the vehicle: most modern EVs are fine with the Type A protection built into the charger, but some older Nissan Leaf, Renault Zoe and specific plug-in hybrid models produce DC leakage current that requires Type B - I'll ask the vehicle model at quote stage.

Can I have two chargers?

On a domestic 100A single-phase supply, two 32A chargers is 64A of charging load alone, which limits everything else in the house. Load-management works but with a Type B or three-phase upgrade needed if both cars want to charge at 7kW simultaneously. Practical answer: one 7kW charger with a switching cable, or split load-management between two chargers each capped at 3.6kW.

Pricing

Standard EV charger install on a Canterbury property with modern consumer unit and headroom in the 100A supply: £720 – £950. Longer cable runs (CT4 villages), listed properties requiring LBC, load-management on a 60A supply, or Type B RCD spec push higher. OZEV grant deducted from the price where eligible. Fixed price quoted in advance after property details and scope. No day-rate creep, no surprise extras.
