Indra Smart LUX vs Rolec EVO: slim and tough, or cheap and British?

Slim and tough, or cheap and British?

Two UK-built chargers, £166 apart. The Indra Smart LUX is the thinnest tethered smart charger you can buy — 78mm of Worcestershire engineering with IP67 and IK10 ratings. The Rolec EVO is £449 from a Lincolnshire manufacturer with a decade of commercial EV charging behind it, and a five-year warranty as standard.

The shortest version:

• Indra Smart LUX — £615. Tethered, exceptionally slim, weatherproof to a degree most homes will never test.
• Rolec EVO — £449. Untethered, quietly excellent, and the smart money if you don't need a fixed cable.

Where the £166 actually goes

It is tempting to read the Smart LUX premium as paying for a brand — it isn't. You are paying for a tethered cable, a 78mm depth that most competitors can't match, and an IP67 rating that means the unit is rated to be submerged. The Rolec EVO, for comparison, is IP54 — fully weatherproof, but not submersible. Both share the same IK10 impact rating, so neither loses a dignity contest with a football.

On smart features the gap narrows dramatically. Both run OCPP 1.6, both do dynamic load balancing, both integrate with solar via an included CT clamp, both authorise with RFID. The Indra Smart LUX claims integration with over 1,000 UK tariffs and will follow half-hourly pricing on something like Octopus Agile; the Rolec app is newer and still maturing through OTA updates, which is the honest case against it. If tariff agility is central to your setup, the Ohme Home Pro at £535 is the more proven tool for that specific job.

The install-cost footnote that changes the maths

Both chargers fold protective hardware into the unit itself. The Rolec EVO includes PME/PEN fault detection, a Type A RCD, and surge protection built in — Rolec's own indication is £150–£250 off install labour on a typical job. The Indra Smart LUX similarly includes SPD and PEN fault detection, worth roughly £150 off labour.

Effective fitted cost on the Rolec settles close to £850 on an easy install. The Smart LUX sits closer to £1,025 fitted direct from Indra. That £175-ish delivered gap tracks the £166 unit gap almost exactly — meaning the question is which charger you want on the wall, not which install quote looks kinder.

Tethered vs untethered, which matters here

This is the cleanest fork in the road. The Smart LUX is tethered only — no socket version exists. The EVO is untethered only — no tethered option. If you have one EV that lives in one driveway, tethered is the quieter life: plug straight in, no cable to fetch from the garage. If you have two EVs with different connector preferences, a future car in mind, or an aesthetic preference for a clean socket when idle, untethered wins.

Cable length on the Smart LUX is 6 metres standard or 10 metres for £55 more. With the EVO you buy your own cable, typically £120–£180 for a good five-metre Type 2, which narrows the price gap by around a third if you need one.

Renters and flat owners

Both chargers are OZEV-approved, so the £500 grant applies if you qualify. Against the Rolec EVO at £449, the grant covers the unit outright and chips into the install. Against the Smart LUX at £615, it takes the unit down to £115 on the nose and the install still has to be paid. The grant flatters the cheaper charger, as it usually does.

The verdict

Buy the Indra Smart LUX if:

• You want a tethered cable and a slim profile on a visible wall
• Your install location is exposed — coastal, open, unsheltered
• You prefer buying direct from a UK manufacturer with strong tariff coverage

Buy the Rolec EVO if:

• You want an untethered socket and don't mind supplying your own cable
• Five-year warranty as standard matters more than a three-year one
• You want the lower out-of-pocket cost after install savings

On a wall, we'd put the Rolec EVO. £449, five-year warranty, Red Dot–awarded casework, built in Boston — it is the harder charger to argue against for most single-EV households. The Smart LUX is the right answer in specific cases: tethered preference, tight garage walls, punishing weather. Those buyers will know it. Everyone else should keep the £166.
