Marketed on V2G readiness. Vehicle-to-grid — the trick where your EV sells stored energy back during peak hours — is still a distant promise in the UK; supporting tariffs, compatible cars, and DNO paperwork all have to line up. The Zaptec Go 2 is the only AC home charger certified ready for it, so if V2G does land in a few years, you won't be replacing hardware to join in. If it doesn't, you've paid a modest premium for a feature you can't yet use.
Set V2G aside and the Go 2 is a quietly capable untethered charger. MID-approved energy meter — legally certified readings, which matter for workplace reimbursement and for any future V2G billing. Subscription-free 4G built in. Auto-switches between 7.4kW single-phase and 22kW three-phase depending on what the supply can deliver. 3.2 kg: the second-lightest mount here after the Easee One, and ahead of the EO Mini Pro 3. Five-year warranty. It is not the cheapest untethered option, and at £638 the specifics have to work hard to earn the £149 gap over the Easee.
Best for: Buyers willing to bet on V2G arriving in the next few years, workplace-reimbursed drivers who need certified metering, or anyone who wants free-for-life 4G in a compact untethered unit.
Installation
Fitting the Zaptec Go 2.
3.2 kg, 240 × 180 × 106 mm — one of the easier units to mount; only the Easee One (1.5 kg) and EO Mini Pro 3 (2.5 kg) are lighter. The charger senses whether your supply is single- or three-phase and adjusts its output accordingly, so a future supply upgrade needs no new hardware. No built-in RCD or SPD; both added at the consumer unit. Subscription-free 4G removes any Wi-Fi-reach concerns about the mounting position. Untethered: the wall stays clean, but you bring your own Type 2 cable. IP54 — fine for sheltered outdoor spots. Full walkthrough in our install guide.

Tariff compatibility
What it costs to run.
Scheduling runs through the Zaptec app. The MID-approved meter matters here: readings are legally certified, which earns its keep if you're reimbursed by a workplace or landlord and anyone asks for receipts. No direct supplier API, so no automatic half-hourly chase on Octopus Agile or extra Intelligent Go slots — that's the Ohme Home Pro's job. Schedule-based integration is fine for Octopus Go and similar fixed-window tariffs. OCPP 1.6J compliance lets the charger plug into third-party energy-management platforms, which will matter more once V2G tariffs arrive. Full pattern in our EV tariff guide.

Less £500 if you qualify for the OZEV grant.
Against the field
How it compares.
Vs Indra Smart PRO: both play in V2G-adjacent territory, but the Zaptec is the one that's actually certified. The Indra throws in a surge protection device instead — a different bet on where the value lives, and £243 cheaper for making it. Vs Easee One: £149 gap for V2G-ready, MID metering, longer warranty, three-phase. Vs Wallbox Pulsar Max: Wallbox is smaller, tethered and £125 less; the Zaptec is lighter, untethered, and V2G-ready.
