Tesla Wall Connector vs Ohme Home Pro: the £57 question

The £57 question

Two tethered 7.4kW chargers, £57 apart. The Tesla Wall Connector at £478 is the official unit, cheaper than most third-party boxes, with a 7.3-metre cable and a four-year warranty. The Ohme Home Pro at £535 talks directly to your energy supplier — Octopus, OVO, British Gas — and schedules itself around the cheap half-hours.

That's the whole pitch, on both sides. The decision sits almost entirely on your tariff.

• Tesla Wall Connector — £478, longest cable here, native Tesla app. Manual scheduling. The quiet default for fixed-window tariffs.
• Ohme Home Pro — £535, supplier-integrated, OZEV-approved, IP65. The charger that does the tariff hunting for you.

Is the Ohme's £57 premium worth it?

It depends which tariff you're on, and whether you plan to switch.

On Octopus Go, the window is fixed: 8.5p/kWh from 00:30 to 05:30, every night. The Tesla's built-in scheduler handles that in ninety seconds of setup. The Ohme's supplier integration adds nothing you can't get with a kitchen timer. Save the £57.

On Octopus Agile, rates move every thirty minutes, with off-peak slots drifting around a 5p/kWh floor. Set-once scheduling can't follow that. The Ohme Home Pro can, because the Ohme app ingests Agile's half-hourly price feed and aims the session at the cheapest slots. Over a year, the saving usually covers the £57 several times over.

On Octopus Intelligent Go, things flip again. Tesla cars have native API integration with Octopus, so a Tesla on Intelligent Go already gets half-hourly smart scheduling through the car itself — no charger intelligence required. The Ohme's advantage collapses here; the Tesla does the job for £57 less. That's the one scenario where being a Tesla owner actively argues against the Ohme.

On OVO Charge Anytime or British Gas Electric Drivers, you need a charger the supplier talks to. OVO's scheme in particular manages charging through the charger rather than a fixed window. The Ohme is on the approved list. The Tesla isn't.

The grant tips the price the other way

The Tesla Wall Connector isn't OZEV-approved, so it doesn't qualify for the £500 grant regardless of who you are. The Ohme Home Pro does qualify — but only if you rent, or own a flat.

For that narrower group of buyers, the £500 wipes out the £535 unit price almost entirely and contributes to the install as well. In that case the Ohme isn't £57 more expensive than the Tesla; it's effectively £478 cheaper. If you're a renter or flat owner on a smart tariff, the decision is made before we start.

For a homeowner with a driveway — most readers — the grant is irrelevant and the £57 gap is real.

Cable, weather, warranty

A few details worth naming.

Cable: 7.3 metres on the Tesla, 5 metres on the Ohme as standard. If the charger is going on the far side of the garage from where the car parks, that's a decisive difference. The Ohme does an 8-metre option but it costs extra, narrowing the price gap further.

Weather: Tesla rates the Wall Connector IP44, Ohme rates the Home Pro IP65. On a sheltered garage wall, IP44 is fine. On an exposed gable in Aberdeen, IP65 earns its keep.

Warranty: four years Tesla, three years Ohme. Neither is class-leading — the Simpson & Partners Home 7 does ten, the Rolec EVO does five — but the Tesla edges it.

Solar: neither charger is the answer for solar households. The Ohme has built-in diverting, which is better than nothing, but serious PV owners should look at the Ohme vs Zappi GLO comparison instead.

The verdict

Buy the Tesla Wall Connector if:

• You're on Octopus Go, Intelligent Go, or any flat-rate tariff
• You need a cable longer than 5 metres without paying extra
• You own a Tesla and want the app you already have to handle everything

Buy the Ohme Home Pro if:

• You're on Agile, OVO Charge Anytime, or plan to switch to a dynamic tariff
• You qualify for the OZEV grant (renter or flat owner)
• Your wall is fully exposed and you want IP65

For the median Tesla owner — driveway, Octopus Go, dry-ish wall — the Tesla Wall Connector at £478 is the charger to put up. For anyone on a tariff that actually moves, the Ohme Home Pro earns its £57 back inside a couple of months and then quietly keeps earning.
