Smart LUX

The thinnest tethered smart charger on the UK market — 78 mm deep, so it sits almost flush against the wall. The Tesla Wall Connector is 124 mm deep, the Zappi GLO 130 mm; the Smart LUX is roughly half as proud of the wall as either. For narrow passageways, tight garages, or discreet front-of-house installations, the form factor is the point.

The other headline is protection: IP67 + IK10. IP67 means fully dust-tight and able to survive temporary submersion — unlike the IP65 most weatherproof chargers here carry, which handles water jets but not standing water. IK10 is the highest impact rating available. If you park in a flood-prone area, near a rough driveway, or anywhere the unit will take real-world knocks, this is the most protected home charger you can buy. UK-designed and manufactured in Worcestershire by Indra, the UK's leading V2G developer — though the Smart LUX itself isn't V2G-capable.

Best for: Installations where the charger has to sit discreetly against the wall, or anywhere weather and impact ratings matter more than the average.

Installation

3.6 kg with the 6-metre cable (a touch more with 10 m), 201 × 306 × 78 mm. That 78 mm depth is the headline — the thinnest tethered smart charger in this selection, by a clear margin. Built-in SPD (surge protection) and PEN fault detection usually take £150–£250 off install labour combined, since the electrician doesn't need to source or fit either at the consumer unit. Still needs a Type A RCD adding. Wi-Fi as standard; Ethernet or 4G optional at roughly £250 extra — steep enough that a Wi-Fi extender often makes more sense unless cellular is genuinely required. IP67 means low-mounted positions in areas of surface water or coastal spray are viable; IK10 handles the rest. Full walkthrough in our install guide.

Tariff compatibility

Indra claims integration with over 1,000 UK tariffs, which is the broadest coverage of any charger here on paper: Octopus (Go, Agile, Cosy, Intelligent Go), OVO, British Gas, EDF, E.ON, smaller providers. On Octopus Agile, the app reads next-day half-hourly prices and schedules into the cheapest slots, much as the Ohme Home Pro does. On fixed-window tariffs like Octopus Go, set the window and the charger does the rest. In practice, the Ohme's direct API link to Octopus for Intelligent Go slot-negotiation is marginally cleaner. Solar PV diversion via a CT clamp is comparable to Sync Energy's SolarCharge — a step below the Zappi GLO's three-mode system. OCPP 1.6J compliance opens the door to third-party energy management. Full pattern in our EV tariff guide.

Price

Mid-range. A 6-metre version is also available at variable retail pricing. The optional 4G add-on is steep against the Ohme ePod's included cellular SIM — if 4G is essential, an Ohme is probably the simpler buy. Eligible for the £500 OZEV grant for renters and flat owners.

Against the field

Against the Ohme Home Pro: the Indra is slimmer and tougher (IP67 vs IP65); the Ohme has deeper Intelligent Go integration, a colour display, and bundled 4G. Against the Zappi GLO: similar price territory, but the Zappi's surplus-solar logic is more sophisticated; if solar is the priority, the Zappi. Against Simpson & Partners and Andersen: competes on British manufacturing at a lower price, with different design priorities — slim and protected rather than architectural. The practical limit is brand visibility: no Amazon listing, so buy direct from Indra.
