Tesla Wall Connector (Gen 3) vs NexBlue Point 2

The £59 between a known quantity and a forward bet

The Tesla Wall Connector (Gen 3) costs £475. The NexBlue Point 2 costs £534. That £59 gap is small enough to disappear into installation costs — and large enough to buy a meaningfully different charger.

• Tesla Wall Connector — £475, tethered, 7.3-metre cable, manual scheduling through the Tesla app. The default for anyone who values simplicity.
• NexBlue Point 2 — £534, untethered, V2G-ready hardware, tariff automation via EcoPilot, lifetime 4G eSIM, and a five-year warranty. The spec sheet of a charger twice its price.

What the NexBlue's £59 buys you

Start with tariff intelligence. The Tesla Wall Connector lets you set a charge schedule — pick a start time, pick a stop time, done. That is perfectly adequate on Octopus Go, where the cheap window is a fixed 00:30–05:30 block. Set it once; forget it.

On Octopus Agile, rates shift every thirty minutes. A static schedule cannot chase them. The NexBlue's EcoPilot integration can — it reads half-hourly prices and charges when they're cheapest. At Agile's average overnight lows of around 5p/kWh, versus the 20p+ daytime peaks, the maths favours automation quickly. The same applies to Intelligent Go, where the NexBlue can slot charging into the 23:30–05:30 window and accept bonus cheap slots pushed by Octopus.

Then there is V2G. The NexBlue ships with ISO 15118 and OCPP 2.0.1 hardware — the protocols that bi-directional energy flow will run on. No UK home V2G tariff is widely available yet, so this is a bet on the next two to three years rather than a feature you use tomorrow. But it means the NexBlue will not need replacing when that market arrives. The Tesla Wall Connector has no bi-directional capability and no OCPP support at all.

Other details that stack up: the NexBlue includes a CT clamp for dynamic load balancing, has a built-in 4G eSIM with lifetime-free connectivity (no reliance on your home Wi-Fi), and carries IP54 plus IK10 impact resistance — comfortably above the Tesla's IP44. If your charger sits on a fully exposed wall, that rating gap is not trivial.

Where the Tesla Wall Connector still makes sense

Convenience, mostly — and that is not a small thing. The Tesla is tethered with a 7.3-metre cable, the longest in the market at this price. You pull up, plug in, walk away. The NexBlue is untethered only; you supply your own Type 2 cable, coil it, store it. For a daily home routine, tethered wins on ease.

If you own a Tesla, the Wall Connector app integration is native. Charge history, power sharing across up to six units, over-the-air updates — all through the app already on your phone. No second app, no new account, no learning curve.

And the price is simply lower. £475 against £534. On a straightforward fixed-rate tariff like EDF GoElectric at 6.99p/kWh between 23:00 and 06:00, a manual schedule does the same work as the NexBlue's automation. The extra intelligence has nothing to optimise.

The OZEV question

This matters for eligible buyers — renters and flat owners. The NexBlue Point 2 is OZEV-approved; the Tesla Wall Connector is not. The £500 grant applied to the NexBlue's £534 price leaves just £34 for the unit itself, with the rest contributing to installation. Applied to the Tesla? It cannot be — the grant is unavailable. For anyone who qualifies, this alone can settle the decision.

Which to buy

Buy the Tesla Wall Connector if:

• You want a tethered charger with a 7.3-metre cable and zero fuss
• You are on a fixed off-peak tariff where manual scheduling does the job
• You already live inside the Tesla app and do not want another one

Buy the NexBlue Point 2 if:

• You are on a variable tariff — Agile, Intelligent Go — and want the charger to chase cheap rates for you
• You want V2G-ready hardware that will not need swapping in two years
• You qualify for the OZEV grant, which covers the unit price and bites into installation

The honest tension here is brand maturity. The Tesla Wall Connector has years of UK installations behind it; NexBlue does not. A five-year warranty mitigates that, but it does not erase it. If you value a proven track record above all else and your tariff is simple, the Tesla at £475 is the quieter, cheaper choice. If your tariff rewards intelligence — or you want the hardware to be ready for whatever the grid does next — the NexBlue earns its £59 premium.
