Tesla Wall Connector vs Indra Smart PRO: the £121 question

The £121 question

On paper this looks straightforward: the Tesla Wall Connector is £478, the Indra Smart PRO is £599, and the Tesla has the longer cable, the bigger app ecosystem, and the better warranty. £121 less for the obvious choice.

The paper is misleading. What the Indra actually sells is a box with a surge protection device and a CT clamp already inside it — both of which a thorough installer would otherwise add to the Tesla's bill. Whether the £121 is a premium or a rebate depends entirely on the quote your electrician hands you.

• Tesla Wall Connector — the Tesla-owner default. £478, 7.3-metre cable, native app, no grant.
• Indra Smart PRO — British-built, OZEV-approved, with solar and surge protection already in the box.

What the Indra actually includes

The Smart PRO ships with a surge protection device (SPD) and a CT clamp for solar monitoring. On a typical UK install, the SPD adds £100–£150 to labour and parts; the CT clamp another £50–£100 if you ever want solar integration. Tot those up and the Indra's £599 sticker can effectively land below £450 on the wall.

The Tesla Wall Connector has neither. Its spec sheet is explicit that the installer adds the RCD and any surge protection separately, and there is no native solar diverting without third-party hardware. For a bare-bones install on a covered wall, that's fine and the Tesla is cheaper. For a fully weatherproofed outdoor install on a house with — or planning — solar panels, the Indra's bundle does real work.

The tariff and grant picture

Neither charger is the best in class for smart-tariff hunting. The Indra Smart PRO integrates with Octopus Intelligent Go, Octopus Go, OVO Charge Anytime and EDF GoElectric, and does a perfectly competent job on any of them. The Tesla relies on manual schedules, which suits fixed-window tariffs like Octopus Go or E.ON Next Drive and starts to look thin on Octopus Agile.

For buyers whose whole reason for upgrading is tariff automation, the Ohme Home Pro at £535 is the charger to look at — and the Ohme vs Indra comparison sharpens that trade-off. The grant story is clearer: the Tesla isn't OZEV-approved, so renters and flat owners who qualify for the £500 grant cannot use it on the Tesla at all. The Indra is approved and eligible, which for that buyer covers most of the unit cost and chips into install labour too.

When the longer cable wins

The Tesla's 7.3-metre tethered cable is the longest in this round-up. The Indra's 6 metres is respectable and beats the Ohme Home Pro's 5 metres, but if your parking spot is at an awkward angle to the consumer unit — or you ever need to charge a second car parked behind the first — that extra 1.3 metres quietly matters more than any smart feature.

Two other things go the Tesla's way. Power sharing across up to six units on one circuit is useful on driveways with two EVs or in small landlord installs. And OTA updates mean the charger acquires new behaviour without another installer visit, which is a quieter form of future-proofing than the Indra's speculative V2G pedigree — the Smart PRO itself doesn't support vehicle-to-grid today.

The verdict

Buy the Tesla Wall Connector if:

• You own a Tesla and want the native app, no middleman
• The parking geometry wants every inch of cable
• Your tariff is fixed-window and your install is straightforward

Buy the Indra Smart PRO if:

• Your installer would otherwise quote an SPD and CT clamp separately
• You have solar panels or plan to add them
• You qualify for the £500 OZEV grant and need an approved charger

For a Tesla owner on a single-phase supply, with a covered wall and a fixed-window tariff, the Tesla is the charger we'd put up — £121 cheaper, longer cable, app already on the phone. For anyone commissioning an outdoor install with solar in the picture, the maths flips and the Indra lands on the wall for less. Solar-first buyers should also weigh the Zappi GLO comparison, which is the more honest fight for that use case.
