Indra Smart PRO vs EVEC VEC03: Where does the £230 go?

£369 vs £599 — and neither price tells the full story

Both the EVEC VEC03 and the Indra Smart PRO play the same trick: stuff protection hardware inside the unit so the electrician's bill drops. The EVEC bundles a Type A RCD with 6 mA DC leakage detection and PEN fault protection — components that typically add around £100 to an install. The Indra bundles a surge protection device (SPD), normally £100–£150 extra, plus a CT clamp for solar. The sticker gap is £230. The gap on the wall, after install, is narrower — but it still favours the EVEC.

• EVEC VEC03 — £369, the cheapest OZEV-approved smart charger on the market. Built-in RCD and PEN protection. No smart-tariff link. App is functional but unreliable by reputation.
• Indra Smart PRO — £599, British-made, with included SPD and CT clamp. Direct scheduling for several UK smart tariffs. App is basic but the tariff hooks work.

What the Indra's £230 buys you

Three things. First, smart-tariff integration. The Indra Smart PRO talks to Intelligent Octopus Go, OVO Charge Anytime, Octopus Go, and EDF GoElectric directly. It can schedule around off-peak windows without you touching the app each night. The EVEC has no tariff API at all — it is not on any supplier's compatible-charger list. You set a timer manually, and if the timer misfires (a reported issue), the car charges at peak rate.

Second, solar diversion out of the box. The Indra's CT clamp is included; the EVEC's is an extra purchase. For a household with panels already on the roof, the Indra is ready to divert surplus generation on day one. That said, buyers whose solar ambitions extend further — battery storage, full ecosystem control — will find the myenergi Zappi GLO or GivEnergy EV Charger more capable, and the Zappi GLO vs Indra comparison covers that ground.

Third, a metre of cable. The Indra's 6-metre tether reaches a little further than the EVEC's 5 metres. Not a headline feature, but it matters if the consumer unit sits at the far end of the garage.

The EVEC's case: cheap enough to not care

The EVEC VEC03 does not try to be clever. It charges at 7.4 kW, it has OCPP 1.6J support (so third-party platforms like Monta can manage it), and its built-in protections shave roughly £100 off the electrician's quote. At £369, it is £36 cheaper than the Easee One and £93 less than the VCHRGD Seven Pro. For grant-eligible buyers — renters and flat owners — the £500 OZEV grant covers the £369 unit outright and contributes toward install costs too.

The trade-off is software. The EVEC app's reliability is the recurring complaint in owner feedback: scheduled sessions that do not start, Wi-Fi drops with no 4G fallback. On a flat-rate tariff like the standard variable, none of that matters much — the car charges overnight regardless. On a time-of-use tariff where hitting the right window saves real money, an unreliable scheduler is a problem. And on a half-hourly variable tariff like Octopus Agile, the EVEC cannot participate at all.

Who should look elsewhere entirely

If tariff optimisation is the priority and you are willing to spend more, the Ohme Home Pro at £535 is the market's strongest tariff charger — and the Ohme vs Indra comparison details why it usually outperforms the Indra on that front too. If you want the cheapest possible tethered unit and do not care about OZEV approval, the Sync Energy Wall Charger 2 undercuts the EVEC at £362.

The verdict

Buy the Indra Smart PRO if:

• You are on a smart tariff — Intelligent Go, OVO Charge Anytime, Go, or GoElectric — and want the charger to schedule itself.
• You have solar panels and want a CT clamp included, not added to the bill.
• Your install quote already includes an SPD line item you can now delete.

Buy the EVEC VEC03 if:

• You are on a flat-rate or simple two-rate tariff and do not need tariff automation.
• You want the lowest possible outlay — £369 for the unit, with built-in RCD and PEN protection trimming the install.
• You are a renter or flat owner eligible for the OZEV grant, where the £500 wipes out the unit price entirely.

For most buyers reading this page — people on a standard tariff, or on a fixed off-peak window they can set once — the EVEC VEC03 does the job for £230 less. The Indra Smart PRO earns its premium only when the tariff integration or the solar CT clamp would otherwise cost you that difference anyway. If neither applies, keep the £230.
