GivEnergy EV Charger vs EVEC VEC03: The £109 battery question

The £109 that only a battery justifies

The GivEnergy EV Charger costs £478. The EVEC VEC03 costs £369. Both are tethered, 5-metre-cable, single-phase, OZEV-approved units with three-year warranties. On paper, they look like two budget chargers separated by £109 and not much else.

That £109 buys exactly one thing: the ability to pull stored energy from a home battery into your car. If you have that battery, the GivEnergy is a specialist tool that few competitors match. If you do not, it is an overpriced charger with an underwhelming app — and the EVEC, for all its own rough edges, does the same job for less.

• GivEnergy EV Charger — £478. The charger for home-battery owners. Battery-to-EV and solar divert through the GivEnergy portal. Ordinary at everything else.
• EVEC VEC03 — £369. The cheapest OZEV-approved smart charger available. Built-in RCD and PEN fault protection trim installation costs. Software is the weak point.

Battery-to-EV: the GivEnergy's only argument

Most chargers with solar divert mode can route live generation to the car. The GivEnergy goes further — it draws from a home battery, not just from panels producing at that moment. Charge the battery overnight at 7p/kWh on Octopus Intelligent Go, then push that stored energy into the car the next afternoon. The car charges from yesterday's cheap rate, the panels refill the battery, and the grid barely notices.

This works with GivEnergy's own batteries and compatible third-party units. It slots into the GivEnergy monitoring portal, so battery state, solar generation, and EV draw sit on one screen. For households already running a GivEnergy storage system, the charger is the obvious — perhaps the only sensible — addition.

Without a battery, the picture changes. The GivEnergy's app is basic compared with the Ohme Home Pro or Hypervolt Home 3 Pro. There is no live supplier API, no half-hourly tariff optimisation, no integration with Octopus Agile. It schedules charges by time window and that is the extent of it. At £478 with those limitations, it is a hard sell against the field — the Easee One at £405 is cheaper and more refined, and the Ohme Home Pro at £535 is smarter by a wide margin.

The EVEC's trade-off: price versus polish

The VEC03's appeal is arithmetic. At £369 it is the cheapest OZEV-approved smart charger on the market. The built-in Type A RCD with 6 mA DC leakage detection and PEN fault protection means the electrician does not need to supply those components separately — typically saving around £100 on installation. Total outlay, charger plus install, can land below £750.

For grant-eligible buyers — renters and flat owners — the £500 OZEV grant covers the £369 unit price outright and chips into the installation bill. That is a low barrier to entry by any measure.

The compromise sits in the software. The EVEC app has earned a reputation for intermittent scheduled charging and Wi-Fi connectivity issues. There is no 4G fallback; if your home network drops, the charger loses its brain. OCPP 1.6J support means you can run it through Monta or another third-party back-end, which is a useful escape hatch — but it requires a degree of tinkering most buyers did not sign up for.

The IP rating confusion — EVEC's own documents cite IP54, IP55, and IP65 in different places — is not confidence-inspiring. It will almost certainly survive a British winter, but the inconsistency suggests documentation that has not kept pace with the product. Worth verifying at point of sale.

Where neither charger is the right answer

If your priority is smart-tariff integration — chasing half-hourly rates on Octopus Agile, or letting Intelligent Go manage your sessions automatically — neither the GivEnergy nor the EVEC belongs on your wall. The Ohme Home Pro at £535 speaks directly to your supplier's API and earns its premium back within a year on a variable tariff. For solar owners without a battery, the myenergi Zappi GLO is the benchmark — our Zappi GLO vs GivEnergy comparison covers that ground in detail.

The verdict

Buy the GivEnergy EV Charger if:

• You already own a GivEnergy or compatible home battery and want battery-to-EV charging
• You use the GivEnergy monitoring portal and want the car on the same dashboard
• Solar divert plus battery drawdown — not just live generation — matters to your energy strategy

Buy the EVEC VEC03 if:

• You want the lowest possible outlay for an OZEV-approved smart charger
• You are on a flat-rate or simple two-rate tariff and need scheduled charging, nothing fancier
• You are grant-eligible and want the £500 OZEV grant to cover the unit and part of the install

For most buyers without a home battery, the honest recommendation is neither of these two. The Easee One at £405 — just £36 more than the EVEC — offers a more reliable app, a lifetime 4G SIM as backup connectivity, and a tidier product overall. It is the better default. The GivEnergy earns its place only in the specific setup it was designed for: a home with stored energy and nowhere else to send it but the car.
