Build Quality and Design
The Gen 3 has a clean, slim profile in matte white that sits neatly on a wall without dominating the space. Tesla has put care into the design: it looks considered rather than purely functional, which matters when it is mounted at the front of a property.
The 7.3m tethered cable is one of the longest available on a home charger at this level. It reaches most driveways and garage layouts without needing extensions. The cable is flexible and easy to handle day to day.
The unit carries an IP44 weather rating, suitable for UK outdoor conditions including rain and general exposure. For a sheltered garage wall or covered installation point, it performs reliably.
Installation
The Gen 3 requires a 32A dedicated circuit, standard for any 7.4kW home charger. Any NICEIC or NAPIT-registered electrician can carry out the installation, and the unit is straightforward to mount and wire.
Your installer will add Type A RCD protection and a surge protection device at the consumer unit as part of a complete installation. The charger is designed for fixed wall mounting and suits both indoor and outdoor positions.
Note that the Tesla Wall Connector Gen 3 is not currently OZEV-approved, so it does not qualify for the UK EV Chargepoint Grant. If grant funding is important to your decision, speak to ON-EV and we can help you find the right solution.
Charging Speed
On a standard single-phase UK supply, the Gen 3 delivers 7.4kW, adding roughly 25 to 30 miles of range per hour. For most drivers that means a full charge overnight from whatever state the battery is in when they arrive home.
On three-phase supplies, the unit steps up to 22kW, one of the highest outputs available for a home AC charger. This makes it a strong option for properties with three-phase electricity and vehicles capable of accepting higher AC charging rates.
Charging speed is determined by your vehicle's onboard charger. The Gen 3 is built to supply whatever your car can accept, up to its rated maximum.
App and Smart Features
The Gen 3 connects to the Tesla app via Wi-Fi, giving you full visibility of charging sessions, energy usage, and scheduling from your phone. For Tesla vehicle owners, this integrates directly with the existing app used to manage the car, keeping everything in one place.
Scheduled charging lets you set off-peak windows to take advantage of cheaper overnight electricity rates. The charger also receives over-the-air firmware updates from Tesla, meaning improvements and new features arrive automatically without any engineer visit.
The unit supports power sharing across up to 16 Wall Connectors on a single circuit. This allows multiple chargers to balance the available current automatically, making it well suited to multi-vehicle households and small commercial properties.
Compatibility
Despite being a Tesla product, the UK Gen 3 uses a standard Type 2 connector and is fully compatible with any EV sold in the UK. Whether you drive a Tesla, a Volkswagen ID.4, a BMW iX, or any other electric vehicle, the Wall Connector will charge it.
This makes it a future-proof choice. If you change vehicles down the line, the charger works with whatever you replace it with.
