The Indra Smart Pro is a British-made 7.4kW smart home EV charger priced from £899 installed, combining broader UK tariff compatibility than most rivals with genuine CT-clamp solar surplus matching. It suits drivers on a named smart tariff — Octopus Intelligent Go, OVO Charge Anytime, E.ON Next Drive and many others — and solar households who want their car to charge from surplus without switching charger brands. The one meaningful caveat: vehicle-to-grid (V2G) and vehicle-to-home (V2H) remain trial-only; buyers who need bidirectional charging today should look elsewhere.
- Power: 7.4kW single-phase (32A)
- Cable options: 6m or 10m tethered, or untethered socket
- Price from: £899 installed (verify current pricing at indra.co.uk)
- Editor score: 8.7 / 10
Indra Smart Pro verdict: is it the right charger for you?
Buy it if:
- You are on or plan to switch to a UK smart EV tariff — Octopus Intelligent Go, OVO Charge Anytime, British Gas Electric Driver, EDF GoElectric, or E.ON Next Drive
- You have solar panels and want surplus-matching charging via a CT clamp without buying a myenergi Zappi
- You want a British-made product with a 3-year manufacturer warranty
- You value tariff breadth over design flair
Skip it if:
- You need full V2G or V2H bidirectional charging today — the Smart Pro trial is not a commercial product
- You want the absolute cheapest option and are happy with a simpler unit: see the cheapest EV chargers UK guide
- You want Ohme’s deeply integrated Octopus IG extended-window behaviour — the Ohme ePod is more tightly coupled to the Octopus API

2026 smart tariff compatibility
Indra markets the Smart Pro as compatible with over 1,000 UK energy tariffs. That claim reflects the charger’s flexible scheduling architecture rather than 1,000 individually tested integrations — in practice it means the app can work with any tariff that provides an off-peak window or rate schedule, not just a pre-approved list. For a broader guide to choosing a smart tariff, see our UK EV smart tariff guide.
The key integrations for 2026:
| Tariff | Off-peak window | Off-peak rate (indicative April 2026 — verify with supplier) | Smart Pro integration | Notes |
|---|---|---|---|---|
| Octopus Go | 00:30–05:30 | ~8.5p–9.5p/kWh | Yes, via Octopus API | Fixed window, simple setup |
| Intelligent Octopus Go | 23:30–05:30 (extendable) | ~7p/kWh | Yes, Intelligent API | Extended cheap windows via demand management |
| OVO Charge Anytime | Anytime (EV load only) | ~7p/kWh | Yes, via OVO API | Add-on to standard OVO tariff |
| British Gas Electric Driver | 00:00–05:00 | ~8p–9p/kWh | Yes, scheduled | Schedule-based, no live API |
| EDF GoElectric | 00:00–05:00 | ~9p/kWh | Yes, scheduled | Verify current 2026 product name |
| E.ON Next Drive | 00:00–07:00 | ~6.7p–9p/kWh | Yes, scheduled | Longer window than most |
| Indra Energy (own-brand) | Varies | Check supplier | Yes, native | Available via Indra customer journey |
Rates are indicative April 2026 estimates. Always verify current rates on the supplier’s website before switching.
The native Intelligent Octopus Go integration is the headline integration. Octopus manages the dispatch of cheap windows for enrolled chargers via its API; the Smart Pro participates in this ecosystem, meaning on nights when Octopus extends the cheap window for grid demand management, the Smart Pro charges at 7p beyond the standard 05:30 cut-off.
For the Ohme ePod, that extended-window behaviour is the deepest in the market. The Smart Pro delivers it well, though Ohme’s implementation is sometimes credited with marginally faster response to Octopus dispatch signals.
Solar diversion and surplus matching
Solar charging is where the Indra Smart Pro differentiates itself most clearly from budget smart chargers. A CT clamp installs at your consumer unit and measures the direction and size of energy flow at the grid connection. Three modes are available:
Solar-only (Eco mode): The charger waits for surplus solar to be detected and starts charging when surplus reaches the minimum threshold — approximately 1.4kW. It modulates its draw up as surplus increases and scales back as it decreases. If surplus drops below 1.4kW, charging pauses. This mode maximises self-consumption and is the right choice on clear, consistent sunny days.
Eco blended mode: The charger charges from solar surplus and supplements with grid power if surplus alone is insufficient to maintain a minimum charge rate. This avoids the stop-start cycling that Solar-only mode produces on cloudy or variable days, delivering steady charging progress.
Boost mode: The charger charges at full 7.4kW from the grid, ignoring solar status. The physical Boost button on the unit itself triggers this mode — a rare and genuinely useful feature that means you do not need to open the app to force a fast charge when you are in a hurry.
For a broader look at solar charging options, see our solar EV charging guide and the best solar EV chargers UK comparison. On solar integration alone, the myenergi Zappi still leads the market with its Eco+ mode’s real-time modulation. The Smart Pro closes the gap and wins on tariff breadth.
Worked savings example: A household with a 4kWp solar array generating approximately 3,400kWh per year, an EV doing 8,000 miles at 3.5 miles/kWh (consuming roughly 2,285kWh), and solar self-consumption of around 1,000kWh into the car (roughly a third of EV consumption from solar at a self-consumption rate of ~30%). At an avoided import rate of 27p versus a 10p export rate, that is a 17p saving per kWh: approximately £170 saved versus exporting the same energy. The precise figure varies with your usage profile, panel orientation, and tariff. Treat this as directional.
App, scheduling and day-to-day use
The Indra app handles scheduling by tariff window, by manual time window, or by a cost-per-charge cap. The interface is functional rather than polished — it shows you what you need but does not have the refined UX of the Hypervolt or Ohme apps. Key day-to-day features:
- Schedule charging by tariff, time window, or cost cap
- Live energy readout: grid, solar, and car in real time
- Physical Boost button on the unit (not just in the app — a practical advantage)
- OCPP 1.6J support for third-party management system integration
- Firmware updates over-the-air via Wi-Fi or Ethernet
- Optional 4G dongle for installations with unreliable or absent Wi-Fi at the driveway
The Ethernet port and 4G dongle option are rarely offered by competitors at this price point. For driveways remote from the router, the 4G module removes the Wi-Fi coverage issue entirely.
Installation: what the £899 price includes
The standard Indra installation price covers:
- Up to 15m of cable run from the consumer unit to the charger mounting position
- Connection at the consumer unit (existing board assumed suitable)
- Wall mounting of the unit
- Earth rod if required by the installer’s assessment
- Commissioning and app setup
Extras commonly quoted separately:
- Consumer unit upgrade if the existing board is full or outdated
- Cable runs over 15m
- Trenching or surface trunking across hardstanding
- Bollard mount instead of wall mount
- DNO notification handling if your total load approaches 100A
A realistic fully-installed cost with one or two extras is typically £950 to £1,150. The OZEV chargepoint grant (up to £350) applies for residents of flats and rented accommodation — confirm eligibility at gov.uk before purchasing.

Indra Smart Pro vs rivals
| Indra Smart Pro | myenergi Zappi | Ohme ePod | Hypervolt Home 3 Pro | |
|---|---|---|---|---|
| Tariff integration | Broadest — 1,000+ including IG native | Octopus Flux native | Octopus IG native (deepest) | Octopus IG native |
| Solar modes | Three (Solar, Eco blend, Boost) | Three + Eddi surplus diversion | Limited (CT clamp only) | Three |
| Physical Boost button | Yes | No | No | No |
| V2G | Trial only | No | No | No |
| UK-made | Yes | Yes (Lincolnshire) | UK-designed | UK-designed |
| Approx. unit price | ~£899 installed | ~£1,099 + install | ~£899 RRP | ~£899 RRP |
| Warranty | 3 years | 3 years | 3 years | 3 years |
Smart Pro vs Zappi: If solar self-consumption is the primary driver, the Zappi’s Eco+ mode is the strongest implementation in the UK market — particularly when combined with the Eddi hot water diverter. The Smart Pro wins on tariff breadth and costs less when comparing installed prices.
Smart Pro vs Ohme ePod: Ohme’s Octopus Intelligent Go API integration is the most precisely tuned in the market for extended cheap-window charging. For drivers who exclusively use Octopus IG and have no solar, Ohme is the cleaner solution. For drivers who want to future-proof across multiple tariffs or add solar later, the Smart Pro has the wider base.
Smart Pro vs Hypervolt Home 3 Pro: Hypervolt leads on design and app UX; the Smart Pro leads on tariff breadth and has the physical Boost button advantage. Neither has a home battery product; both are well-suited to solar households.

Frequently Asked Questions
Is the Indra Smart Pro a good charger? Yes, particularly for tariff-led buyers and solar owners. The combination of broad UK tariff compatibility (including native Intelligent Octopus Go integration), CT-clamp solar matching, and British manufacture gives it a strong value case at its price point. The main limitation is the trial-only V2G status and app UX that lags behind Ohme and Hypervolt.
Does the Indra Smart Pro work with Octopus Intelligent Go? Yes. The Smart Pro has native Intelligent Octopus API integration — Octopus controls the charge window, and the off-peak 7p rate applies during those windows. On nights when Octopus extends the cheap window for grid demand management, the Smart Pro continues charging at 7p beyond the standard 05:30 cut-off.
Can the Indra Smart Pro charge from solar panels? Yes, via an installed CT clamp. Three modes (Solar-only, Eco blended, Boost) let you choose between surplus-only charging, grid-supplemented charging, and full grid. Solar-only mode modulates between 1.4kW and 7.4kW to match available surplus. A CT clamp must be fitted at the consumer unit during installation for solar modes to function.
How much does the Indra Smart Pro cost to install in the UK? From £899 including a standard installation (up to 15m cable run). Typical real-world cost is £950 to £1,150 with minor extras such as consumer unit work or longer cable runs. The OZEV chargepoint grant of up to £350 reduces this for eligible flat and rented accommodation residents.
Does the Indra Smart Pro support V2G or V2H? Not as a commercial product. Indra has run V2G and V2H trials, but the current Smart Pro unit is a unidirectional charger. Buyers who need bidirectional charging should verify the current status of Indra’s V2G programme at indra.co.uk, or consider an alternative product.
