The smart-charging and tariff specialist with V2G heritage.
Indra Smart PRO & Smart LUX
Indra is a British company that made its name in intelligent, grid-aware charging, including early work on vehicle-to-grid (V2G) technology, where the car can feed power back to the grid. That heritage shows in its home units: the Smart PRO and the design-led Smart LUX are built around getting the most out of a smart electricity tariff. Both are 7kW, both come tethered or untethered, and both lean on app-led scheduling and tariff integration to shift your charging into the cheapest windows. If you want a charger from a brand that treats tariff optimisation as the point rather than an add-on, Indra is worth a look.

Who the Indra suits
Drivers who want the charger to do the money-saving for them on a smart or dynamic tariff, and who like that Indra has built its name on intelligent, grid-aware charging rather than just a box on the wall.
In short: Pick Indra if you want a smart charger built around squeezing the most out of a tariff, from a brand with genuine grid-aware and V2G heritage; the Smart LUX if you also want the smarter looks.
What stands out
The strengths that tend to matter when people choose the Indra.
Tariff-led by design
Built around smart-tariff charging, so it shifts your charging into cheap overnight or off-peak windows automatically through the Indra app.
Smart-charging heritage
Indra has a track record in intelligent and vehicle-to-grid charging, so grid-aware, cost-cutting behaviour is core to what it does rather than bolted on.
Tethered or untethered
The Smart PRO and Smart LUX both let you choose a built-in cable or a socket, and the LUX adds a more design-led finish if looks matter.
Smart features & tariffs
This is Indra's strong suit. The units integrate with smart and time-of-use tariffs through the app and target the cheapest half-hourly or off-peak slots, so paired with a good EV tariff they do the cost-cutting for you. It sits closer to the tariff-optimising end of the market than to the plug-in-and-forget end.
EV tariffs in NI explainedSolar charging
Indra's focus is tariff-led, grid-aware charging rather than solar surplus diversion. There is app-led smart charging, but if charging primarily from your own panels is the main aim, a Zappi remains the more direct choice.
Compare with the ZappiTethered or untethered?
Both the Smart PRO and the more design-led Smart LUX come tethered or untethered, so you can pick a built-in cable for grab-and-go convenience or a socket for a tidier wall and your own lead. Same charging smarts across the range.
Electrically it makes no difference: it's a 7kW charge either way. Tethered is grab-and-go convenient; untethered keeps the wall tidy and your cable flexible. If you're unsure, note it on your quote and the installer will advise for your driveway.
Things to weigh up
No charger is right for everyone. The points below aren't dealbreakers, just the trade-offs to factor in.
- The big savings come when it is paired with a smart or dynamic EV tariff; on a flat-rate tariff you lose much of its advantage.
- Its calling card is tariff and grid-aware charging rather than native solar surplus matching, so solar-first homes often look at the Zappi.
- The range spans the Smart PRO and the pricier, more design-led Smart LUX, so check which model, and which cable style, you are being quoted for.
Whichever charger you choose, the install must be notified to NIE Networks, which is a legal requirement in NI. Our registered installers handle that paperwork as standard. See the full cost breakdown, check your grant, or see how comparing 3 quotes works.
