The OZEV Grant — Who Is Still Eligible?
The Office for Zero Emission Vehicles (OZEV) EV chargepoint grant was closed to homeowners in April 2022. However, grants remain available in specific circumstances:
- EV chargepoint grant for renters and flat owners: Up to £350 (or 75% of installation cost) for people who rent or own a flat. The property must have dedicated off-street parking
- Landlord EV charging grant: Up to £350 per socket, up to 200 sockets per application, for landlords installing chargepoints at residential properties. A significant opportunity for portfolio landlords
- Workplace Charging Scheme: Businesses and charities can claim up to £350 per socket for workplace chargepoints
To claim any grant, the installer must be OZEV-approved. Prestige Engineers are OZEV-approved installers and can process grant applications on your behalf.
The EV Smart Charge Point Regulations 2021
Since 30 June 2022, all new private EV chargepoints installed in the UK must comply with the Electric Vehicles (Smart Charge Points) Regulations 2021. These regulations require that chargepoints:
- Are capable of smart charging (responding to signals from electricity networks and suppliers)
- Have a randomised delay feature to prevent simultaneous charging at peak times
- Can communicate with smart meters
- Are capable of being controlled remotely
All chargepoints we install comply with these regulations. Non-compliant chargepoints installed before the deadline can remain in use but cannot be replaced with non-compliant units.
PME Earthing and TT Conversion
The most common complication for London properties is the earthing system. Many London homes are supplied via a Protective Multiple Earthing (PME) system, where the neutral conductor is used as the earth return. Under PME, the EV charger must be fitted with an earthing device to prevent the risk of electric shock via the vehicle chassis in the event of a neutral fault.
Options include:
- PEN fault detection device: An electronic device fitted in the charger that disconnects in a PEN fault condition. Required by IET Code of Practice for EV Charging Equipment Installation (4th Edition, 2020)
- TT earthing system: Converting the charger supply to a separate TT earthing system (earth rod) isolates it from PME. Cost: £300-600 for rod installation and rewiring the charger supply
Prestige Engineers carry out an earthing assessment before every installation and recommend the appropriate solution. All installations comply with BS 7671:2018 and the IET Code of Practice.

Frequently asked questions
Can I install an EV charger in a rented property in London?
Yes, if you have the landlord's permission and the property has dedicated off-street parking. You may also be eligible for the OZEV renter grant (up to £350). The installation must be carried out by an OZEV-approved installer.
What is the fastest home charging speed available in London?
Most London homes have a single-phase 100A supply, which supports a maximum of 7.4kW charging (approximately 30 miles of range per hour). Three-phase supplies support 22kW (90 miles per hour) but are uncommon in residential properties. Commercial installations can go higher.
How long does EV charger installation take?
A standard single-phase home EV charger installation takes 3-5 hours including earthing assessment, cable run, consumer unit connection, and commissioning. More complex installations with TT earthing conversion or long cable runs take a full day.
Do I need planning permission for an EV charger in London?
Generally no — EV charger installation is permitted development under Class A of Part 2, Schedule 2 of the GPDO (as amended). Exceptions include listed buildings, certain conservation areas, and where the charger would be within 2 metres of a highway. If in doubt, check with your local planning authority.
