Is It Worth It?
The Zaptec Go 2 is not the smartest home charger for automated tariff savings. It is not the cheapest. And its headline feature — vehicle-to-grid — cannot yet be used by any UK household.
What it is, is the most future-proofed home EV charging device you can buy in the UK today. The V2G hardware is certified, not hypothetical. The 4G connectivity removes reliance on your home Wi-Fi, which matters in garages and outbuildings. The MID-approved energy meter provides legally certified charge readings — something that most home chargers cannot offer, and that genuinely earns its keep for anyone claiming business mileage.
The Zaptec Go 2 makes most sense when you plan to own it for five years or more, you use it in a location with unreliable Wi-Fi, or you need certified energy data for business purposes.
Charging Performance
Power Output and Auto Phase-Switching
The Go 2’s most technically interesting charging feature is its ability to automatically switch between 7.4kW single-phase and 22kW three-phase depending on your property’s electrical supply. Most UK homes are single-phase, which means you will charge at 7.4kW — the same as any other standard home charger, adding roughly 25 to 30 miles of range per hour.
If your property has three-phase supply, the Go 2 can deliver up to 22kW — approximately 75 miles of range per hour. The auto-switching means you buy one piece of hardware that works optimally on either supply type. Most rivals require you to choose at purchase.
Compact Scandinavian Design
At 240mm x 180mm x 106mm and 3.2kg, the Zaptec Go 2 is one of the most compact and lightweight smart home chargers available in the UK. The minimalist white casing reflects Norwegian design heritage and blends unobtrusively on most external walls.
Untethered Only
The Go 2 is untethered — a Type 2 socket rather than a fixed cable. This adds flexibility but means you must supply your own cable at additional cost (budget £100 to £200 for a good quality cable). Factor this in before comparing prices with tethered competitors.
Weatherproofing
The Go 2 is IP54 rated, protected against water splashing from any direction. This is adequate for most UK outdoor installations but lower than some rivals. If your installation is in a particularly exposed location, IP65-rated chargers offer higher protection.
Smart Features and App
The Zaptec App
The Zaptec app handles scheduling, energy monitoring, and remote control. You can set charging times to align with your tariff’s off-peak window and check live session data. The app connects via Wi-Fi as the primary channel, with 4G as a fallback.
Multiple reviewers describe the app as functional and clear, though less sophisticated than app-first chargers. What it cannot do is automatically optimise for half-hourly variable pricing or communicate directly with your energy provider to claim additional off-peak slots.
MID-Approved Energy Meter
The built-in MID-certified meter’s energy readings are legally certified — the same standards used for utility billing and commercial metering. This matters if you are claiming business mileage reimbursement or require ERE (Electricity Reimbursement Evidence) certification. Most home chargers do not have MID-certified meters. The Go 2 does.
Subscription-Free 4G
Every Zaptec Go 2 includes a built-in 4G SIM with no ongoing subscription cost. The charger uses the mobile network as the primary or fallback connection for app communication, remote monitoring, and OTA firmware updates. For installs in garages, outbuildings, or driveways that are some distance from the router, this is the most immediately useful everyday distinguishing feature.
V2G, Solar and Future-Proofing
What V2G-Ready Means
The Go 2 includes ISO 15118-20 and a Power Line Communication (PLC) module — the hardware and software standard required for vehicle-to-grid energy flow. In a functioning V2G system, your EV’s battery would be able to export electricity back to your home or the national grid during peak demand periods.
When Will V2G Actually Work in the UK?
Not yet — and there is no confirmed UK launch date. V2G over AC requires compatible vehicles (currently very few UK EVs support bidirectional AC charging), approved V2G tariffs from suppliers, and Distribution Network Operator (DNO) approval — none of which are widely available as of April 2026.
Research from Cornwall Insight suggests that by 2030, V2G could earn participating EV drivers an average of £320 per year through grid export. That is a projection, not a current reality.
Buying the Zaptec Go 2 for V2G today means buying hardware that is ready for a feature that does not yet exist in usable form. If V2G becomes mainstream within the next five years, you will not need to replace your charger to join in.
Solar Charging
The Zaptec Go 2 supports solar panel integration to prioritise surplus generation for charging. This feature is available via the Zaptec Sense, an optional add-on that is not included in the base price. Solar integration without the Sense is not supported. Confirm the current cost of the Sense unit with your installer before purchasing.
How It Compares
Zaptec Go 2 vs Humax MX7
Both are V2G-ready home chargers at a similar price range. The Zaptec Go 2 adds subscription-free 4G and a MID-approved energy meter. The Humax MX7 adds RFID access control (with two tags), interchangeable fascia plates, a London Design Award, a tethered cable option, and OTA firmware updates.
If MID metering or 4G connectivity are the priority, the Zaptec has the edge. If RFID access, design recognition, and tethered cable convenience matter more, the Humax is the stronger buy.
Zaptec Go 2 vs Ohme Home Pro
The Ohme Home Pro is the stronger choice if your priority is automated smart tariff savings. Its direct API connection to Octopus Intelligent Go means it can claim additional off-peak slots automatically. The Zaptec Go 2 wins on V2G readiness, three-phase auto-switching, the MID meter, and 4G connectivity.
Zaptec Go 2 vs Easee One
The Easee One is £95 cheaper and also Scandinavian-designed with built-in 4G. The Go 2 adds V2G-ready certification, a MID-approved meter, auto three-phase switching, and a 5-year warranty. The Easee wins on tethered/untethered switching via app and a wider choice of colours.
Frequently Asked Questions
Is the Zaptec Go 2 available to buy in the UK now? Yes. The Go 2 launched in the UK in late 2025 and is available through EV charger retailers and the Zaptec UK website. Installation must be carried out by a qualified electrician.
Does the Zaptec Go 2 work with Octopus Intelligent Go? Schedule-based charging works with Octopus Go and similar fixed-window tariffs. The Go 2 does not have a direct API connection to Octopus Intelligent Go, so it cannot automatically claim additional off-peak slots. For Intelligent Go users who want full automation, the Ohme Home Pro is the stronger option.
What does V2G-ready mean, and when will it actually work in the UK? V2G-ready means the Go 2 includes the hardware and communication protocol (ISO 15118-20) needed for vehicle-to-grid energy flow. The feature is not yet active in the UK. It requires compatible vehicles, V2G energy tariffs from suppliers, and DNO approval — none of which are widely available as of April 2026.
How does the Zaptec Go 2 differ from the original Zaptec Go? The Go 2 adds V2G-ready hardware, a MID-certified energy meter, automatic phase-switching between 7.4kW and 22kW, subscription-free 4G, a built-in display, and a five-year warranty (compared to three years on the original Go).
Is the Zaptec Go 2 OZEV approved? Yes. Eligible renters and flat owners can claim up to £500 off the installation cost through the government’s OZEV grant, which runs until March 2027.
Can the Zaptec Go 2 charge at 22kW on a standard home supply? Only if your property has a three-phase electrical supply. The majority of UK homes are single-phase, which caps the Go 2 at 7.4kW. Your installer can confirm your supply type before purchase.
