Tesla Wall Connector (Gen 3) vs Andersen Quartz

The £197 question: function or furniture

The Tesla Wall Connector (Gen 3) costs £475. The Andersen Quartz costs £672. Both deliver roughly 7 kW on a single-phase home supply. Both are tethered Type 2 chargers that will fill a Tesla — or any other EV — overnight. The £197 gap buys nothing extra in speed. What it buys is everything around the speed: materials, weatherproofing, warranty length, solar awareness, and the right to choose from eleven colour finishes plus Accoya wood or carbon inserts.

That is either a bargain or a waste, depending entirely on what you care about when you look at your driveway wall.

• Tesla Wall Connector — £475, 7.3-metre cable, four-year warranty, IP44. The default for Tesla owners who want the native app and nothing more.
• Andersen Quartz — £672, 5.5-metre cable (8.5 m for £99 extra), seven-year warranty, IP65, built-in solar diversion, eleven finishes. The charger for people who mind what's bolted to their house.

Where the Tesla's simplicity works — and where it doesn't

The Tesla Wall Connector does one thing well: it charges your car, on your schedule, through an app you already have on your phone. Set a departure time or an off-peak window, and it obeys. On a fixed-window tariff like Octopus Go — 8.5p/kWh between 00:30 and 05:30 — that manual schedule is all you need. The 7.3-metre cable is the longest of any charger on the site, which matters if your parking spot and your consumer unit are on different sides of the house.

The limits are plain. IP44 is the minimum outdoor rating — fine under an eave, less convincing on a fully exposed south-facing wall where rain drives sideways. There is no built-in RCD or PEN fault detection, so your installer adds both, nudging the install cost upward. And the charger cannot talk to your energy supplier: it has no Intelligent Octopus Go integration, no OVO Charge Anytime link, no half-hourly rate chasing. If you want a charger that hunts cheap slots for you, the Ohme Home Pro at £539 is the comparison that matters — covered in detail on the Tesla vs Ohme page.

What the Andersen Quartz adds for £197

Three things stand out. First, the seven-year warranty — nearly double the Tesla's four. Over seven years of daily use, that coverage has tangible value; a replacement control board in year five is not a hypothetical expense.

Second, IP65 weatherproofing. The difference between IP44 and IP65 is the difference between "protected against splashing" and "protected against water jets from any direction." For an exposed wall, that rating removes a worry.

Third, solar diversion. The Quartz ships with a CT clamp and Adaptive Fuse logic that routes surplus generation into the car without extra hardware. The Tesla Wall Connector cannot do this at all without a separate diverter. If you have panels and no battery, the Quartz earns back a chunk of its premium by displacing grid imports on sunny afternoons. Buyers whose solar setup is the primary concern may also want to weigh the myenergi Zappi GLO at £599, which treats solar diversion as its entire reason for existing.

The Quartz also integrates with Intelligent Octopus Go and OVO Charge Anytime — a step up from the Tesla's manual-only scheduling, though still not in the same league as the Ohme Home Pro on variable tariffs like Octopus Agile.

Then there is the design. Eleven finishes is not a gimmick; it is the reason Andersen exists as a company. If a charger's appearance on a period property matters to you — stone cottage, listed building, timber-frame barn conversion — the Quartz is one of very few units that won't look like a plastic gadget screwed to the brickwork. If that sentence doesn't describe your house, the premium is harder to justify.

Neither qualifies for the grant

Both the Tesla Wall Connector and the Andersen Quartz sit outside the confirmed OZEV-approved list, so the £500 grant is off the table for either. For renters and flat owners who qualify, this is a significant miss — that £500 would cover a Tesla Wall Connector outright and chip into the install, or knock the Andersen Quartz down to £172 before fitting. But the grant is only available on approved units. If eligibility matters, the Easee One at £489 or the Ohme Home Pro at £539 are the places to look.

The verdict

Buy the Tesla Wall Connector if:

• You want the cheapest path to a reliable overnight charge and the Tesla app is already on your phone
• Your charger sits under cover or in a garage — IP44 is sufficient
• You have no solar panels and use a fixed off-peak tariff

Buy the Andersen Quartz if:

• A seven-year warranty matters more than saving £197 today
• The charger will live on an exposed wall and you want IP65 confidence
• You have solar panels and want diversion without buying a separate box

For most Tesla owners on a standard single-phase supply, the Wall Connector at £475 does the job and nothing more — which is a compliment. The Andersen Quartz is for the smaller group of buyers who care what a charger looks like, how long it is guaranteed, and whether it can absorb afternoon sunshine. That group knows who it is. Everyone else should pocket the £197.
