Smart PRO

A quietly practical charger that earns its keep at install time. Indra includes a surge protection device in the box — the component BS 7671 regulations now require, and which most other chargers make your electrician source and install separately for £100–£150. They throw in the CT clamp for solar diversion too. So while the unit says £599 on the sticker, the real-world installed cost usually lands below that of chargers pitched at £450.

Indra themselves are the UK's leading V2G technology developer, though the Smart PRO itself is a standard AC charger — not V2G-capable today. Buying it is a small bet that Indra's V2G kit, when it arrives, will be easier to add to an existing Indra installation than to retrofit from scratch. Outside that optimism, it's a solid British-made charger: 6-metre tethered cable (longer than the Ohme's 5 m), RFID lock, dynamic load balancing, schedule-based smart-tariff support. Not the flashiest unit on the market — the deliberate kind of solid.

Best for: Buyers who'd rather minimise install labour via the included SPD and CT clamp, plus anyone who likes the idea of sitting in Indra's ecosystem for future V2G.

Installation

Mid-sized at 5 kg, 340 × 240 × 115 mm. Tethered 6-metre cable, longer than the Ohme Home Pro's 5 m; an untethered version exists. The install advantages are the bits already in the box. The SPD saves the electrician sourcing, fitting, and charging for a separate surge protection device at the consumer unit — £100–£150 on most jobs, and required by the 18th Edition of BS 7671 for most new charger installations. The CT clamp for solar goes on the meter tails during the standard fit. Dynamic load balancing is built in, so the charger throttles itself rather than tripping your main fuse. No built-in RCD; still added at the consumer unit. IP54 — fine for sheltered outdoor positions. Full walkthrough in our install guide.

Tariff compatibility

Schedule-based integration via the Indra app, compatible with Octopus Intelligent Go, Octopus Go, OVO Charge Anytime, and EDF GoElectric. You set the off-peak window, the charger draws during it. No direct supplier API, so no automatic chase of Agile half-hours or dynamically expanded Intelligent Go slots — the Ohme Home Pro still owns that space. The RFID lock is a quiet extra for shared-drive households and workplace-reimbursement drivers who need per-card usage logs. Full pattern in our EV tariff guide.

Price

Mid-range on the sticker. Real-world cheaper: the included SPD typically takes £100–£150 off install labour, the CT clamp another £50–£100 if you want solar. On a typical job, the effective unit cost lands closer to £399–£449 — territory the Tesla Wall Connector and Easee One play in, with extras most of them don't include. Eligible for the £500 OZEV grant for renters and flat owners.

Against the field

Vs Zaptec Go 2: both sit V2G-adjacent. The Zaptec is the one certified V2G-ready; the Indra is in the V2G-maker's ecosystem without being V2G-capable itself. The Zaptec bets on certification; the Indra bets on the included SPD earning its keep today. Against the Easee One: £194 cheaper on paper, less so after install extras. Against the Tesla Wall Connector: the Tesla's £121 cheaper with a longer cable; the Indra's included SPD often erases that gap at install time.
