Price & Value
The Easee One is £194 cheaper at £405 compared to the Indra Smart PRO at £599.
When you factor in professional installation (typically £400–£600), the total installed cost for the Easee One is approximately £805–£1005, while the Indra Smart PRO comes in at around £999–£1199. Fully installed, the Easee One remains the more affordable option.
If you're eligible for the OZEV grant (available to renters and flat owners), you can claim £350 off the installation cost. That would bring the effective unit-plus-install price down to roughly £455–£655 for the Easee One and £649–£849 for the Indra Smart PRO. Both chargers are OZEV-approved, so eligibility depends on your living situation rather than the charger itself.
Looking at overall value, the Easee One offers a compelling combination of price and features at £405. The Indra Smart PRO at £599 may still be the better buy if its specific feature set — such as indra app — is important for your setup. The best value depends on which features you'll actually use day-to-day.
Power & Charging Speed
Both the Easee One (7.4kW) and Indra Smart PRO (7.4kW) are single-phase chargers, delivering around 7–7.4kW on a standard UK home supply.
On a standard UK single-phase supply, both will charge a Tesla Model 3 Long Range (75kWh battery) from 20% to 80% in approximately 5–6 hours overnight. Even a Tesla Model Y with its larger battery completes a typical daily top-up well within an overnight window. For the vast majority of UK Tesla owners, single-phase 7kW charging is more than sufficient — you'll wake up to a full battery every morning.
Cable length is an often-overlooked consideration. The Easee One comes with a Untethered (use own cable) cable, while the Indra Smart PRO has a 6 metres cable. A longer cable gives you more flexibility for driveway positioning — particularly useful if your charger is mounted on a side wall but your Tesla's charge port is on the rear left. Measure your likely cable run before buying to ensure the cable reaches comfortably without being fully stretched.
For most Tesla owners who plug in when they get home, both chargers provide more than enough power for a full overnight charge. The real-world difference between 7kW and 7.4kW is negligible — roughly 20 minutes over a full charge cycle. Unless you have a three-phase supply and regularly need rapid top-ups during the day, charging speed should not be the deciding factor between these two chargers.
Smart Features
The Easee One offers: Easee app, Dynamic load balancing, Scheduled charging, Built-in eSIM (lifetime 4G), Wi-Fi backup, Expandable (up to 3 chargers). The Indra Smart PRO offers: Indra app, Smart tariff integration, Solar mode (CT clamp included), Dynamic load balancing, Surge protection (SPD) included, RFID lock.
Breaking these down by category: for connectivity, the Easee One uses Built-in eSIM (lifetime 4G), Wi-Fi backup, while the Indra Smart PRO uses its companion app. For energy management, the Easee One provides Dynamic load balancing, compared to the Indra Smart PRO's Dynamic load balancing. Solar and scheduling features are covered in the dedicated sections below.
The most meaningful differentiators: the Easee One uniquely offers Easee app, Scheduled charging, Built-in eSIM (lifetime 4G), Wi-Fi backup, Expandable (up to 3 chargers), while the Indra Smart PRO exclusively provides Indra app, Smart tariff integration, Solar mode (CT clamp included), Surge protection (SPD) included, RFID lock. These unique features often determine which charger is the better fit — if a feature on one charger's exclusive list is a must-have for you, that should heavily influence your decision.
The app experience matters as much as the feature list — you'll use it daily. The Easee app is straightforward and reliable, though it offers fewer analytics than some competitors. The Indra app provides standard charging management features. Both apps are available on iOS and Android, but user reviews suggest the day-to-day experience can vary significantly between brands.
Solar Compatibility
The Indra Smart PRO supports solar integration, allowing you to divert surplus solar energy to charge your Tesla. The Easee One does not have built-in solar diverting. If you have solar panels (or plan to install them), this is a significant advantage for the Indra Smart PRO.
The Indra Smart PRO supports solar diversion through its energy management system. This means it can dynamically adjust the charge rate to match your available solar surplus, minimising grid import. Without built-in solar support, the other charger would need a separate solar diverter or manual scheduling to take advantage of solar generation.
The Indra Smart PRO can work alongside a home battery system to store surplus solar during the day and use it for overnight EV charging, though integration complexity varies. A home battery effectively removes the limitation of only being able to solar-charge while the sun is shining — you generate during the day, store it, and charge your Tesla overnight for free.
A typical 4kW solar array in the UK can provide approximately 1,400–1,700 kWh of free EV charging per year, worth £390–£475 at standard electricity rates (around 28p/kWh). For context, the average UK Tesla owner drives around 8,000 miles per year, requiring roughly 2,400 kWh — so solar could cover 60–70% of your annual charging needs. Over the charger's lifetime, solar diversion can save thousands of pounds and significantly reduce your carbon footprint.
Smart Tariff Support
The Indra Smart PRO integrates with smart energy tariffs, automatically charging at the cheapest off-peak rates. The Easee One doesn't have built-in smart tariff integration — you'd need to set manual charging schedules or rely on your car's built-in timer. If you're on (or considering) a smart tariff, this gives the Indra Smart PRO a meaningful advantage in running costs.
The Indra Smart PRO supports smart tariff scheduling with popular EV tariffs including Octopus Go (~8.5p/kWh) and similar time-of-use plans. The most popular UK EV tariffs include Octopus Intelligent Go (~7p/kWh), Octopus Go (~8.5p/kWh), OVO Charge Anytime (~14p/kWh), and British Gas EV Power+ (~7.9p/kWh). Check compatibility with your specific energy provider before making a decision.
The Indra Smart PRO integrates with smart tariffs to schedule charging during off-peak windows, reducing your per-kWh cost significantly. Without this integration, the Easee One can still charge off-peak using manual schedules or your Tesla's built-in timer — but you lose the automatic optimisation and any extended off-peak windows that provider integration unlocks.
The financial impact is substantial. Switching from a standard variable tariff (~28p/kWh) to Octopus Intelligent Go (~7p/kWh) saves approximately £400–£600 per year for a typical Tesla owner driving 8,000–10,000 miles annually. Even moving to Octopus Go (~8.5p/kWh) or British Gas EV Power+ (~7.9p/kWh) delivers savings of £350–£500 per year. A charger with smart tariff integration ensures you capture these savings automatically, every single night, without having to remember to set timers.
Warranty & Build Quality
The Easee One comes with a 3 years warranty, while the Indra Smart PRO offers 3 years. Both offer the same warranty length, so neither has an advantage here. Both are OZEV-approved and suitable for outdoor installation — a longer warranty provides more peace of mind for a product that lives outside year-round and is exposed to British weather.
For weatherproofing, the Easee One is rated IP54 (weatherproof) (splash-proof — protected against splashing water from any direction), while the Indra Smart PRO is rated IP54 (weatherproof) (splash-proof — protected against splashing water from any direction). A higher IP rating means better protection against rain, hose water, and dust. In practical terms, any rating of IP54 or above is suitable for a UK outdoor installation, but a higher rating provides extra confidence in extreme weather — particularly relevant if your charger is exposed rather than sheltered under a car port.
Build quality is reflected in the materials and construction. The Easee One weighs 1.5 kg with dimensions of 256mm × 193mm × 106mm, while the Indra Smart PRO weighs ~5.0 kg with dimensions of 340mm × 240mm × 115mm. A heavier charger typically indicates more robust construction, though modern chargers use high-quality polycarbonate housings that are both lightweight and impact-resistant. If your charger is in a location where it might get bumped by car doors or footballs, look for IK10 impact resistance in the specs — this is the highest rating and means it can withstand 20 joules of impact (equivalent to a 5kg weight dropped from 40cm).
For extended protection: the Easee One comes with a standard 3 years warranty from Easee. The Indra Smart PRO comes with a standard 3 years warranty from Indra. When comparing warranties, also check what's covered — most warranties cover manufacturing defects and component failure, but may not cover damage from incorrect installation or extreme weather events. Having your charger installed by an OZEV-approved installer typically ensures the warranty remains valid.
Which Should You Buy?
Buy the Easee One if you want the best value for money, or overall quality and user satisfaction matter most, or you want the best value.
Buy the Indra Smart PRO if you have solar panels or plan to install them, or you're on a smart energy tariff like Octopus Intelligent Go, or v2g pioneer.
Our Verdicts
The Easee One is a great choice if you want the simplest, lightest installation and value built-in 4G connectivity. At 1.5 kg it's remarkably light, and the lifetime eSIM means no ongoing connectivity costs. However, it's single-phase only (7.4kW), so don't buy this expecting three-phase 22kW charging. For a simple one-car setup with reliable connectivity, it's excellent value at around £405.
The Indra Smart PRO's killer feature is the included SPD, which genuinely saves you money on installation. If your electrician would otherwise charge £150 for a surge protection device, the Indra effectively costs £449 — making it very competitive. The V2G pedigree is interesting but speculative for now. A practical, honest choice for people who want a solid British-made charger without overpaying for features they won't use.
