Indra Smart LUX

The Indra Smart LUX is the slimmest tethered smart charger on the UK market, with a depth of just 78mm that makes it sit almost flush against the wall. Designed and manufactured in Worcestershire, it is a genuinely UK-made product from a company that specialises exclusively in smart EV charging and vehicle-to-grid (V2G) technology. The Smart LUX packs a remarkable feature set into its razor-thin profile: smart tariff integration with over 1,000 UK energy tariffs, solar PV surplus diversion, dynamic load balancing, OCPP 1.6J compliance, remote locking, and real-time energy monitoring through the Indra app. The distinctive turbine LED status light on the front face pulses and changes colour to indicate charging status, giving you at-a-glance feedback without needing to check the app. Build quality is a standout: the Smart LUX carries IP67 and IK10 ratings, making it the most protected charger on this list. IP67 means it is fully dust-tight and can survive temporary submersion in water (compared to IP65 on most competitors), while IK10 is the highest impact resistance rating available. If you park in a flood-prone area or want maximum durability in an exposed coastal or industrial location, these ratings are genuinely meaningful. Available with either a 6-metre or 10-metre cable, the Smart LUX is positioned as a premium mid-range charger for buyers who want UK manufacturing credentials, class-leading protection, and deep smart features without the design premium of the Andersen A3.

Best for: UK EV owners who want the slimmest wall profile, best-in-class weather and impact protection (IP67/IK10), and deep smart tariff integration from a specialist UK manufacturer.

Installation

The Indra Smart LUX weighs 3.6 kg with the 6-metre cable (slightly more for the 10-metre version) and measures 201mm x 306mm x 78mm. That 78mm depth is the thinnest of any tethered charger on this list -- for comparison, the Tesla Wall Connector is 124mm deep and the Zappi GLO is 130mm deep. This makes the Smart LUX ideal for installations where the charger would protrude into a walkway, narrow passage, or tight garage space. The IP67 rating is particularly relevant for installation planning: unlike IP65-rated chargers that are protected against water jets, the Smart LUX can handle temporary submersion, making it suitable for low-mounted positions in areas prone to surface water flooding. The IK10 impact rating means the enclosure can withstand 20 joules of impact energy -- equivalent to a 5 kg mass dropped from 400mm -- so it can handle accidental bumps from car doors or wayward footballs. The charger includes built-in SPD (surge protection device) and PEN fault detection as standard, which simplifies installation and can reduce costs. However, it does not include a built-in RCD, so a Type A RCD will need to be added at the consumer unit. Wi-Fi connectivity is standard, but if your Wi-Fi does not reach the charger location, Ethernet and 4G connectivity are available as optional extras at approximately £250 additional cost. For most installations, a Wi-Fi extender is a cheaper solution. For a full walkthrough of the installation process, see our complete guide to home EV charger installation.

Tariff Compatibility

The Indra Smart LUX claims integration with over 1,000 UK energy tariffs, which is the broadest tariff compatibility of any charger on this list. This includes Octopus Energy tariffs (Go, Agile, Cosy, Intelligent Go), OVO, British Gas, EDF, E.ON, and many smaller providers. On Octopus Agile, the Indra app reads the next day's half-hourly prices and can schedule charging into the cheapest slots, similar to the Ohme. On fixed off-peak tariffs like Octopus Go, you set your off-peak window and the charger handles the rest. The depth of tariff integration is impressive on paper, though in practice the Ohme's direct API link with Octopus for Intelligent Go (requesting additional off-peak slots) remains slightly more seamless. The solar PV diversion feature works with a CT clamp fitted to your meter tails, detecting surplus generation and diverting it to your car. This is comparable to the Sync Energy's SolarCharge and a step below the Zappi's three-mode system in sophistication. The OCPP 1.6J compliance means the Smart LUX can also be integrated with third-party energy management platforms, which is useful if you have a home battery or more complex energy setup.

Price Breakdown

At £565 for the 6-metre version, the Indra Smart LUX is priced between the Ohme Home Pro (£535) and the Simpson & Partners Home 7 (£649). The 10-metre cable version at £635 is worth considering if you have a longer reach requirement -- it is significantly cheaper than buying a 5-metre charger and then needing an expensive cable extension or repositioning the charger. The 3-year warranty can be extended to 5 years for an additional £100, which is reasonable and brings it in line with the longest warranties on this list. If you need 4G connectivity, the £250 premium is steep compared to the Ohme's included 4G SIM -- this is an area where the Indra falls short on value. If you are eligible for the OZEV grant, the installed cost drops to as little as £365 for the 6-metre version.

How It Compares

The Indra Smart LUX occupies a unique position in the market thanks to its ultra-slim profile and class-leading protection ratings. No other charger matches its combination of 78mm depth, IP67, and IK10. Against the Ohme Home Pro (£535), the Indra is £30 more expensive but offers better build protection (IP67 vs IP65), a slimmer profile, and broader tariff compatibility (1,000+ tariffs vs Ohme's focused provider list). The Ohme wins on direct Intelligent Go API integration, included 4G connectivity, and the colour display. Against the Zappi GLO (£599), the Indra is comparably priced with comparable smart features, but the Zappi's three-mode solar system (Fast/Eco/Eco+) and myenergi ecosystem (eddi, libbi) give it the edge for dedicated solar households. The Indra's UK manufacturing credentials put it in the same conversation as Simpson & Partners and Andersen, but at a lower price point than either. The main limitation is visibility: Indra is a specialist brand that most EV buyers have not heard of, and the lack of Amazon availability means you cannot benefit from Prime delivery or the easy returns process. For buyers who prioritise slim design, maximum protection, and deep tariff integration from a UK manufacturer, the Smart LUX is an excellent choice.
