Tesla Wall Connector London — Gen 3 Single-Phase & Three-Phase Install

Wall Connector Gen 3 is the fixed home unit — 7.4kW single-phase or 11.5/22kW three-phase, Type 2 UK connector, Wi-Fi commissioning, daisy-chainable. Universal Wall Connector adds a built-in J1772/NACS adapter so a single unit charges Tesla and non-Tesla EVs — useful for mixed households. Mobile Connector is the portable 7.4kW unit that ships with the car for occasional 3-pin or commando socket use — not a permanent install.

All UK and European Tesla vehicles use the Type 2 (Mennekes) connector for AC charging, including Model 3, Model Y, Model S and Model X. The NACS / J3400 connector is North America only. The UK Wall Connector Gen 3 ships with Type 2 — there is no NACS variant sold here.

Yes. Tesla Wall Connector Gen 3 is on the Octopus Intelligent Go approved charger list. After install we activate OCPP 1.6 firmware and link the unit to Octopus via the Octopus app — they handle scheduling against your car's state of charge and the 6-hour cheap window. Real-world saving is around £600/year for an 8,000-mile-per-year driver moving from a standard tariff.

Up to six Wall Connectors can be daisy-chained on a single circuit using Tesla's built-in load sharing — one unit is designated master, the rest slaves. The bank shares the available current dynamically, charging one Tesla at full speed if only one is plugged in, or splitting across multiple cars. No external OCPP back-office or load-management module is needed for Tesla-only banks.

Out of the box, the Tesla app controls scheduling, energy reporting and firmware updates. For tariff integration with Octopus, OVO or others, the unit runs OCPP 1.6 firmware that lets the third-party tariff app take scheduling control. You can have both: Tesla app for energy stats, Octopus for tariff scheduling. They do not conflict.

4 years from purchase date, provided the install is performed by Tesla or by a qualified electrician following the Tesla installer manual. We are a qualified installer; our installs preserve the full 4-year OEM warranty plus the 2-year workmanship warranty on the install side.

Tesla's in-house install partner is competitively priced but lead times have stretched to 6–10 weeks across London in 2026. As an OZEV-approved alternative installer we usually quote and install inside 2 weeks. Warranty is preserved either way as long as the installer follows the Tesla manual — which we do.

Yes — 22kW requires three-phase electricity at the property. Single-phase domestic supplies in the UK cap out at 7.4kW (32A). If your property already has three-phase (some newer flats, converted commercial, larger detached homes), 22kW is straightforward. If it doesn't, upgrading purely for a faster home charger rarely makes financial sense — 7.4kW fully charges most batteries inside the off-peak window.

Real-world: 7.4kW single-phase adds about 25 miles of range per hour to a Model 3 Long Range — roughly 175 miles across a 7-hour overnight charge. 11.5kW three-phase adds about 35 miles per hour. 22kW three-phase adds about 65 miles per hour, but the car's onboard AC charger is the limit: a Model 3 caps at 11kW AC, so the full 22kW only helps on Model S Plaid or Model Y Performance with the optional 22kW upgrade.

Yes. Tesla Wall Connector Gen 3 meets all five legal requirements: OCPP smart interface, DC residual current detection at 6mA, default off-peak scheduling, randomised charge-start delay (up to 1,800 seconds) and demand-side response capability. We activate the smart-compliance firmware and register the unit at commissioning.
