Tesla Wall Connector (Gen 3) vs Indra Smart PRO

The £80 gap that understates the real difference

On paper, the Tesla Wall Connector costs £475 and the Indra Smart PRO costs £395. An £80 difference. Straightforward enough — until you open the Indra's box and find a surge protection device and a CT clamp for solar diversion already inside. Those two items typically add £150–£250 to an install quote. Factor that in and the effective cost gap between these two chargers is considerably wider than the sticker price suggests.

• Tesla Wall Connector — £475. The longest cable at 7.3 metres, the best app if you drive a Tesla, and a four-year warranty. No grant eligibility, no solar hardware, no built-in surge protection.
• Indra Smart PRO — £395. OZEV-approved, SPD and CT clamp included, smart-tariff scheduling, IP54 weatherproofing. Shorter cable at 6 metres, a more basic app, and a three-year warranty.

What the Indra puts in the box — and why it matters

Most home charger installs require a Type A RCD and a surge protection device in the consumer unit. The Tesla Wall Connector ships with neither; your electrician supplies and fits them, and you pay for the privilege. The Indra Smart PRO includes an SPD as standard. That single component routinely costs £100–£150 in parts and labour when added separately.

Then there is the CT clamp. If you have solar panels — or plan to — the Indra's included clamp lets the charger divert surplus generation into the car without buying anything extra. The Tesla Wall Connector cannot do solar diversion at all without third-party hardware. For a household already generating its own electricity, the Indra's £395 price tag starts to look like a quiet bargain. Buyers specifically chasing solar integration at a higher spec should also consider the myenergi Zappi GLO — there is a dedicated comparison with the Tesla if that route appeals.

The Tesla app advantage is real — but narrow

The Tesla app is polished. If you own a Model 3 or Model Y, the charger sits inside the same interface as your car: charge history, scheduling, power sharing across up to six units. No second app, no second login. Over-the-air updates have added features since launch and will likely continue to.

The Indra app does the job — scheduling, solar mode, tariff integration — but it is not in the same league for fit and finish. Owners of non-Tesla EVs will not care; they have no Tesla app to begin with, and the Indra's tariff support covers Octopus Intelligent Go, Octopus Go, OVO Charge Anytime, and EDF GoElectric. That is broader tariff compatibility than the Tesla offers, which relies on manual scheduling or — for Intelligent Go users — Tesla's own server-side integration.

One material difference: the Tesla Wall Connector supports three-phase at 22kW. Fewer than 5% of UK homes have three-phase supply, but if yours does, the Indra is not an option — it is single-phase only.

The grant question

The Tesla Wall Connector is not OZEV-approved. The Indra Smart PRO is. For eligible renters and flat owners, the £500 OZEV grant covers the Indra's £395 unit price outright and chips into the install costs too. That is a significant tilt. If you qualify for the grant and are choosing between these two, the arithmetic barely requires a calculator.

Which to buy

Buy the Tesla Wall Connector if:

• You drive a Tesla and want one app for car and charger
• You need the 7.3-metre cable — the longest in this class
• Your home has three-phase power and you want 22kW charging

Buy the Indra Smart PRO if:

• You want the lowest total cost of charger plus install — the included SPD and CT clamp save real money
• You qualify for the £500 OZEV grant, which the Tesla cannot access
• You have solar panels or intend to add them

For a Tesla owner with no solar panels and no grant eligibility, the Wall Connector remains the default — the app integration is worth the £80 premium, and the extra 1.3 metres of cable matters more than people expect on a deep driveway. For everyone else, the Indra Smart PRO is the harder-headed choice. It costs less to buy, less to install, qualifies for the grant, and diverts solar without an upsell. The app is not as slick. The warranty is a year shorter. Neither of those things costs you £150 on install day.

If neither charger quite fits — perhaps you want stronger tariff automation than the Indra offers but do not need solar — the Ohme Home Pro at £539 is the comparison to make next.
