Ohme Home Pro vs Enphase IQ EV Charger 2

£539 against £1,050 — and the gap is wider than it looks

The Ohme Home Pro costs £539. The Enphase IQ EV Charger 2 costs £1,050. That is a £511 difference before anyone picks up a drill. Factor in installation — £400–£500 for the Ohme, £900–£1,300 for the Enphase — and the total outlay diverges further still. These are both 7.4 kW single-phase tethered chargers that will add roughly the same miles per hour to a Tesla. The question is what else each one does with your electricity, and whether that justifies the price.

• Ohme Home Pro — £539. Talks directly to Octopus, British Gas and others. Chases cheap half-hours on your behalf. OZEV-approved. Three-year warranty.
• Enphase IQ EV Charger 2 — £1,050. Built to complete an Enphase solar-and-battery system. MID-certified meter, OCPP 2.0.1, 7.5-metre cable, five-year warranty. OZEV approval not confirmed.

The Ohme's tariff advantage is not close

The Ohme Home Pro has direct API integration with Octopus Intelligent Go, Octopus Agile, Octopus Go, and British Gas EV Power. On Intelligent Go, it charges at 8p/kWh across a six-hour off-peak window — and because Octopus can slot extra cheap half-hours outside that window, the effective cost often drops lower. The charger does this without you setting a timer or opening an app. It is Octopus's officially recommended hardware for that tariff.

The Enphase has no equivalent integration with any UK half-hourly tariff. You can schedule it through the Enphase app, but scheduling is not the same as chasing: a fixed timer cannot respond to a price signal that changes every thirty minutes. If your priority is paying less per kilowatt-hour from the grid — and for most EV owners it should be — the Ohme does the job the Enphase cannot, for £511 less.

When the Enphase earns its keep

The Enphase IQ EV Charger 2 exists to be the fourth piece of an Enphase energy system: microinverters, IQ Gateway, IQ Battery, EV charger. Inside that stack, it does things no other UK home charger does. It can chase solar surplus from as little as 1.38 kW, adjusting current in 1A increments roughly every thirty seconds. It can draw from the battery rather than the grid if the Enphase AI decides that is the better source. And it reports everything — generation, storage, EV consumption — in a single app with MID-certified ±1% accuracy.

If you already own that system, the argument is coherent. One app, one vendor, one support call if something breaks. The five-year warranty is two years longer than the Ohme's. The 7.5-metre tethered cable is among the longest on the market — useful if your consumer unit and parking spot are not on the same wall.

But if you do not already own Enphase solar, none of this applies. The charger needs an IQ Gateway on site for full ecosystem behaviour. Without it, you have a well-built but expensive 7.4 kW charger with no smart-tariff integration and no confirmed OZEV approval. At £1,050 for the unit alone, that is a hard sell when the myenergi Zappi GLO offers solar diverting at £599 with OZEV approval and a three-phase option, or the GivEnergy EV Charger pairs with GivEnergy batteries for £444. Solar buyers without an existing Enphase system will find more on the Ohme vs Zappi GLO comparison.

The grant question

The Ohme Home Pro is OZEV-approved. Eligible renters and flat owners can claim the £500 grant, which brings the unit price from £539 to £39 — the grant covers most of the charger and leaves the install to pay for. The Enphase IQ EV Charger 2 is not confirmed on the current OZEV list. If grant eligibility matters to you, the Enphase is a risk; the Ohme is not.

The verdict

Buy the Ohme Home Pro if:

• You want the lowest running cost from a smart tariff — Intelligent Go, Agile, or British Gas EV Power
• You do not have an Enphase solar system and simply need a capable, well-priced charger
• You are eligible for the £500 OZEV grant and want a confirmed-approved unit

Buy the Enphase IQ EV Charger 2 if:

• You already own Enphase microinverters and an IQ Battery and want single-app control over the whole system
• MID-certified metering and OCPP 2.0.1 compliance matter for your setup
• The longer 7.5-metre cable solves a genuine installation problem the Ohme's 5-metre cable does not

For most Tesla owners — which is to say, anyone without an existing Enphase energy system — the Ohme Home Pro is the obvious choice. It costs £511 less, it talks to the tariffs that save you the most money, and it is OZEV-approved. The Enphase is a fine piece of hardware inside its own ecosystem. Outside it, the price makes no sense.
