Zaptec Go 2 vs EVEC VEC03: The £131 that buys a future

£369 gets you charging. £500 bets on what comes next.

The EVEC VEC03 is the cheapest OZEV-approved smart charger on the UK market — £369, tethered, plug in and go. The Zaptec Go 2 costs £500 and is the only AC home charger in the UK certified V2G-ready. That £131 gap is the price of a technology that barely exists in domestic settings yet.

• EVEC VEC03 — £369, tethered, built-in RCD, the budget baseline. Does the daily job; does nothing clever with your tariff.
• Zaptec Go 2 — £500, untethered, V2G-ready, subscription-free 4G, MID-approved meter. A charger dressed for 2028.

What the EVEC VEC03 does well for the money

The VEC03's strongest card is not the unit price — it is what the unit price *removes* from the install bill. A built-in Type A RCD with 6 mA DC leakage detection and PEN fault protection means your electrician does not need to source and wire a separate protection board. That typically saves around £100 on labour, narrowing the real-world gap with dumb chargers to almost nothing.

OCPP 1.6J support means the VEC03 is not locked to EVEC's own cloud; Monta and other back-ends work. Dynamic load balancing is included. Solar integration via CT clamp is possible, though the clamp is sold separately.

The compromises are in the software layer. The EVEC app has a reputation for intermittent scheduling, and there is no 4G fallback — if your Wi-Fi drops, the charger loses its brain. The 5-metre tethered cable is the shortest in the market; if your parking spot sits any distance from the wall, measure twice. And the VEC03 has no direct integration with any UK smart tariff. You cannot add it to Octopus Intelligent Go or OVO Charge Anytime. A manual timer on Octopus Go — set to the 00:30–05:30 window at 8.5p/kWh — is the best you can do.

What the Zaptec Go 2's £131 actually buys

Three things earn their keep today: a MID-approved energy meter (legally certified readings, useful for company-car reimbursement or landlord billing), subscription-free 4G connectivity, and a 5-year warranty versus the VEC03's three.

The headline feature — V2G readiness — does not earn its keep today. Vehicle-to-grid trials are live in the UK, but commercial domestic V2G tariffs remain scarce, and your car needs to support bidirectional AC charging too. The Zaptec is certified and waiting; the ecosystem is not. If V2G matures within the charger's five-year warranty window, early buyers will look prescient. If it stalls, they paid £131 for a feature they never used. For a deeper look at how the Go 2 stacks up against another V2G contender, the Zaptec Go 2 vs Indra Smart PRO comparison is worth a read.

Note that the Go 2 is untethered. You will need to buy a Type 2 cable separately — typically £60–£120 for a decent 5-metre coiled unit — which pushes the effective gap closer to £200. On the other hand, the untethered format means a tidier wall mount (3.2 kg, smaller than a hardback) and the freedom to swap cable lengths later.

Neither charger talks to your energy supplier automatically. If smart-tariff optimisation matters — and on Octopus Agile it should — both are the wrong choice. The Ohme Home Pro at £535 is the charger that chases half-hourly rates for you. For buyers who want an untethered socket with more software polish and a lower price, the Easee One at £405 sits neatly between these two.

Grant-eligible buyers get an unusual deal on the VEC03

If you rent or own a flat, the £500 OZEV grant covers the VEC03's £369 unit price outright and chips into the installation cost too. That makes it one of the cheapest possible routes onto a compliant home charger. The Zaptec Go 2 is also OZEV-approved, so the same grant brings its effective unit cost to zero — but you still need the cable, and installation for untethered units can run slightly higher if the electrician needs to fit a cable holder or tidy the setup.

The verdict

Buy the EVEC VEC03 if:

• Budget is the deciding factor and you want the lowest all-in cost
• You charge on a fixed-rate or simple two-rate tariff and a manual schedule is fine
• You prefer tethered convenience — cable always attached, no faffing

Buy the Zaptec Go 2 if:

• You want V2G readiness for when the technology arrives domestically
• You need a MID-approved meter for company-car mileage claims or shared billing
• You value 4G backup and a longer warranty over a lower price

For most buyers charging a single car on a standard single-phase supply, the VEC03 does the job and leaves £131 in your pocket — more if you count the cable. The Zaptec is the more interesting product, but interesting and useful are not yet the same thing. Buy the VEC03 now; revisit V2G when it has a tariff attached to it.
