Indra Smart LUX vs Cord Zero

£73 separates two lesser-known chargers — and the cheaper one is harder to fault

The Indra Smart LUX costs £546. The Cord Zero costs £473. Both deliver 7.4 kW on single-phase, both are OZEV-approved, and neither brand is a household name. The gap between them is £73, but the real divergence is in what each charger treats as essential: the Indra prioritises physical build; the Cord prioritises staying connected.

• Indra Smart LUX — 78 mm deep, IP67-rated, built in Worcestershire. The slimmest and toughest tethered smart charger on the UK market. No built-in 4G unless you pay roughly £250 extra.
• Cord Zero — dual Wi-Fi plus 4G with automatic failover, included in the price. Bulkier at 132 mm deep, IP54 only, but currently ships with a free five-year warranty.

The Cord Zero's connectivity advantage is worth more than £73

Wi-Fi reach is the single most common complaint in home-charger forums. The charger sits outside; the router sits inside; the signal has to cross a wall, a garage door, or both. The Cord Zero sidesteps the problem entirely. Its multi-network 4G SIM activates the moment Wi-Fi drops, and it does so without the owner lifting a finger. That failover is baked into the £473 price.

The Indra Smart LUX ships with Wi-Fi only. Ethernet is optional, 4G is an add-on costing around £250. So a connectivity-matched Smart LUX runs close to £800 — suddenly a different conversation. If your Wi-Fi reaches the driveway without trouble, the point is moot. If it doesn't, the Cord has already answered the question.

When the Indra Smart LUX earns its premium

Two scenarios favour the Indra. The first is a tight mounting location. At 78 mm deep and 3.6 kg, the Smart LUX barely protrudes from the wall — almost half the depth of the Cord Zero's 132 mm. On a narrow side passage or a wall beside a pedestrian path, that matters.

The second is exposure. IP67 plus IK10 is the highest protection combination on any home charger we catalogue. IP67 means submersible — not just rain-resistant — and IK10 means it can absorb a serious knock. The Cord Zero's IP54 plus IK08 is adequate for most sheltered UK installations, but a wall that takes direct weather and the occasional football needs something sturdier. The Smart LUX is that something.

Both chargers bundle built-in PEN fault detection and surge protection, which typically shaves £150 or more off install labour. On that front, they are level. The Indra quotes install costs of £300–£500; the Cord, £400–£500. In practice, the difference depends on your installer and cable run, not the charger itself.

Tariff support and solar — close enough to call a draw

Both chargers claim broad EV tariff integration. The Indra cites over 1,000 tariffs; the Cord names Octopus Go, Intelligent Go, OVO Charge Anytime, British Gas EV Power, and EDF GoElectric explicitly. For a fixed off-peak window — set the schedule, forget it — either charger does the job.

For half-hourly tariffs like Octopus Agile, neither charger has the track record of the Ohme Home Pro, which remains the benchmark for automatic slot-by-slot optimisation. If Agile is your tariff, the Ohme Home Pro vs Indra Smart LUX comparison is the more useful page.

Both offer solar compatibility, though neither matches the myenergi Zappi GLO for surplus-only diversion. The Indra ships with a CT clamp for PV diversion; the Cord's solar support is more basic. If solar is the primary reason you are upgrading, both are compromises.

Warranty: the Cord's promotional edge

The standard warranty is three years on both. But the Cord Zero currently ships with a free upgrade to five years. Indra charges £100 for the same extension on the Smart LUX — pushing its total to £646 for equivalent warranty cover. That promotional five-year deal may not last, but while it runs, it tilts the maths further in the Cord's favour.

Which to buy

Buy the Indra Smart LUX if:

• You need the slimmest possible wall profile — 78 mm is unmatched
• Your charger will sit on a fully exposed wall with no canopy or recess
• You already have strong Wi-Fi at the mounting point and don't need 4G

Buy the Cord Zero if:

• Your Wi-Fi is unreliable near the driveway or garage
• You want 4G failover included, not as a £250 add-on
• You prefer the lower upfront cost and a five-year warranty without paying extra

For most UK driveways — sheltered enough, Wi-Fi patchy enough — the Cord Zero at £473 is the more practical buy. It costs less, connects more reliably out of the box, and currently matches the Indra's extended warranty for free. The Smart LUX is the better charger for a narrow passage or a wall that takes everything the British climate can deliver. But that is a specific problem, not a common one.
