Indra Smart PRO review

The Indra Smart PRO is a low-priced, untethered 7.4kW charger with unusually broad tariff support: Intelligent Octopus Go (IOG), OVO Charge Anytime, EDF Smart Charging and E.ON Next Drive Smart. On features alone it would score well. The problem is the evidence about how it holds up, which is the weakest of any charger in our set.

Price and what’s included

Indra sells the Smart PRO “fully installed from” £899. That is a standard installation, and Indra says about 70% of homes qualify. Non-standard work is quoted first, and a refund is available before installation. The What Car? owner paid £949 fitted for the white version. The charger alone is £435 for the untethered black unit at Electricpoint. We found no Amazon UK listing for the charger.

Indra’s own shop now sells only the untethered Smart PRO, so a charging cable is extra. Tethered Smart PRO units (6m and 9.4m) are still listed at retailers, and Indra’s tethered option is now the Smart LUX. See our installation cost guide for what else can move a quote.

Where to buy (prices seen on 10 October 2026, and they can change):

• Indra direct: From £899 including standard installation
• Electricpoint: Charger only: untethered £435; tethered 6m £358.99; tethered 9.4m £399 (2026-10-10)
• B&Q (sold and shipped by Volta Charge Points Ltd): £450 in a search snapshot; not confirmed live
• Egg (Egg-branded Smart PRO): Indra says Egg-branded Smart PRO units can be linked to IOG; Egg's own offer was not checked

Smart features and tariffs

This is the Smart PRO’s strong suit. Octopus lists it as generally available on IOG, and Indra names integrations with OVO Charge Anytime, EDF Smart Charging and E.ON Next Drive Smart. Under IOG the Indra app no longer shows per-charge costs and Indra’s own schedules are disabled. Our Intelligent Octopus Go explainer covers the tariff.

Solar uses the external CT clamp that comes in the box. Charging starts only when export to the grid is 1.4kW or more, so it runs on genuine surplus. With an IOG integration, “Use Solar” adds solar charging around Octopus’s schedules. The same clamp provides “House Fuse Protection” load curtailment, which drops the charger to 6A if it loses contact with the clamp. Read our solar EV charging guide for how the modes behave.

There is a Boost button on the unit and in the app, remote lock and over-the-air updates. Wi-Fi is standard, and Ethernet and 4G cost extra. Indra added an Enode integration for energy-retailer apps in April 2026. OCPP is not advertised. The Smart PRO is not V2G or V2H capable, because it is unidirectional.

Installation and safety

Indra’s patented protection monitors line-to-neutral voltage (207V to 253V) to meet BS 7671 722.411.4.1 (iv) in its default mode, so there is no earth rod. An optional Mode A uses a 300mm reference electrode, which is a voltage reference and not an earth rod. Indra warns not to fit an additional upstream open-PEN device (it names the Matt:e), because that voids the warranty. See our PEN fault and earthing guide.

An upstream 30mA Type A (or Type F) double-pole RCD or RCBO is required, alongside the built-in 6mA DC detection. The enclosure is IK10, and Indra’s product page says IP65. Indra’s own documents conflict: an October 2025 brochure and user guide say IP54. The unit measures 420 x 200 x 130mm and weighs 3.5kg, so it is bulkier than compact rivals. Indra’s product page gives a three-year warranty. What Car? says the latest chargers have five years, and a 2023 press release claimed five, so confirm the term in writing.

What owners report

In the What Car? owner survey (brand-level, published on a page sponsored by Pod), Indra scored 3 out of 5 and ranked 8th of 11, with a reliability score of 1 out of 5. Some 65% of Indra owners reported a problem, mostly with the wallbox and some with the app, the highest of the 11 brands. Indra fixed most free of charge and installation was well rated, but 22% of issues took more than a month to fix. A What Car? tester with a Smart PRO (£949 fitted) found the first unit’s smart features unreliable and had it replaced free. The replacement trips occasionally, though the smart functions, boost button and app connection work well.

The company is the second concern. Indra’s accounts for the year to 31 March 2025 disclose Generation 1 charger failures, a £7.5m loss, a 32% staff cut and reliance on Gulf Oil International. Gulf Oil International ceased to be a person with significant control on 27 January 2026, and two Isle of Man-based individuals were notified. We did not find the reason, and this is a counterparty-risk flag, not insolvency.

How it compares

The Ohme ePod costs slightly more fitted, has a deeper IOG integration and a milder repair record. The Easee One is similarly priced and compact, with OCPP, though its IOG support is only in testing.

Our verdict

We score the Indra Smart PRO 5.9 out of 10. The score is held up by smart features (8.5) and fitted price (7.1), but reliability is 2.0, the second lowest in our set after EO’s 1.7, and warranty is 4.3. If the price is what draws you, the Ohme ePod costs only slightly more fitted and avoids the reliability and counterparty risks. Choose the Indra only if you specifically need its OVO or E.ON Next integration and have an installer who will support it. See the best home EV chargers roundup for the alternatives.
