Indra Smart PRO vs Indra Smart LUX: Same Brand, Which One?

Indra Smart PRO vs Smart LUX: Is Indra's Upgrade Worth It?

This is an unusual comparison because both chargers come from the same Worcestershire manufacturer, deliver identical 7.4kW power, carry the same 3-year warranty, and share the same app. On paper, you might wonder why Indra bothers making two products. In practice, the Indra Smart LUX is a meaningful step up from the Indra Smart PRO in almost every way that matters — and the price gap is surprisingly small.

In a nutshell:

• Indra Smart PRO: The no-frills Indra with built-in SPD and solar mode. Gets the job done.
• Indra Smart LUX: Slimmer, tougher, smarter, and barely more expensive. The one most people should buy.

Is the Indra Smart LUX Really Only £16 More?

Pricing here is a bit nuanced. The PRO costs £599 supply-only. The LUX starts at £615 for the 10-metre tethered cable version — just £16 more. If you want the 6-metre LUX cable, that's actually £670, which is £71 more than the PRO. So the answer depends on which cable length you need.

Here's where it gets interesting: the LUX's estimated installation cost is £300–500, while the PRO sits at £400–600. Both include built-in surge protection, but the LUX also packs PEN fault detection as standard. That could shave another chunk off your electrician's bill. When you factor in total installed cost, the LUX may actually work out cheaper despite its higher unit price.

For the 10-metre cable version at £615, this is almost a no-brainer upgrade.

How Much Tougher Is the Smart LUX?

This is where the gap between these two chargers becomes hard to ignore. The PRO carries an IP54 rating — perfectly adequate for a sheltered wall, but not exactly bombproof. The LUX jumps to IP67 plus IK10. That IP67 rating means it can survive temporary submersion. The IK10 impact resistance means a football, a stray wheelie bin, or a careless reversing manoeuvre won't crack it.

If your charger lives on an exposed driveway or a garage wall that takes the weather, the LUX's protection rating is worth the price difference alone. At 78mm deep and 3.6kg, it's also the slimmest tethered smart charger you can buy in the UK — nearly 40mm thinner than the PRO. On a narrow garage wall or beside a front door, that matters more than specs suggest.

Smart Tariff Integration: Does the LUX Do More?

Both chargers support smart tariff scheduling through the Indra app, but the LUX claims integration with over 1,000 UK energy tariffs, including variable-rate tariffs like Octopus Agile. The PRO's tariff integration is described in broader terms — "major UK providers" — without the same specificity.

If you're on a straightforward off-peak tariff like Octopus Go, either charger will schedule your charging just fine. But if you're on Agile pricing and want your charger responding to 30-minute price slots automatically, the LUX's deeper integration is the safer bet. Check our EV tariff comparison to see which tariff suits your driving pattern.

The LUX also supports OCPP 1.6, an open communication protocol that future-proofs it for third-party energy management platforms. The PRO doesn't list OCPP support. For most homeowners today, that's academic. In two or three years, as home energy management gets more sophisticated, it could matter.

Solar Diversion: Both Include CT Clamps

Credit to Indra — both chargers include CT clamps for solar PV surplus diversion at no extra cost. That's a feature some competitors charge £50–80 extra for. If you have solar panels and want to charge your Tesla with excess generation, either the PRO or LUX will handle it. No meaningful difference here.

Which Should You Buy?

Buy the Indra Smart PRO if:

• You want the cheapest possible Indra charger, full stop
• Your charger will live in a sheltered or indoor location where IP54 is fine
• You're on a simple off-peak tariff and don't need Agile-level integration
• You prefer the 6-metre cable and don't want to pay £670 for the LUX equivalent

Buy the Indra Smart LUX if:

• Your charger faces the elements — exposed driveways, coastal locations, anywhere weather hits hard
• You want the slimmest possible unit on your wall
• You're on or considering a variable smart tariff like Octopus Agile
• You want OCPP support for future energy management flexibility
• You'd use the 10-metre cable (at £615, it's barely more than the PRO)

For most Tesla owners browsing our best Tesla home charger guide, the Smart LUX is the obvious pick from Indra's range. It's better built, better protected, and smarter — and the price premium ranges from negligible to non-existent depending on cable length. The PRO isn't a bad charger, but the LUX makes it redundant for all but the most budget-conscious buyers.
