Indra Smart PRO vs Rolec EVO: Which UK-Built Charger Deserves Your Wall?

Two British-Made Chargers, One Clear Winner on Value

Here's a matchup that looks close on paper: two UK-manufactured smart chargers, both at 7.4kW, both with solar integration and dynamic load balancing included. But the Rolec EVO at £449 and the Indra Smart PRO at £599 are separated by more than just £150. They differ in warranty length, safety features, connectivity, and design philosophy — and those differences matter.

In a nutshell:

• Indra Smart PRO: Tethered option, built-in SPD, positioned for future V2G upgrades
• Rolec EVO: More features for less money, 5-year warranty, built-in PME fault detection

Does the Rolec EVO's Feature Set Justify Its Lower Price?

This is the unusual comparison where the cheaper product actually has the longer spec sheet. The Rolec EVO includes Wi-Fi 6, Bluetooth 5.0, and Ethernet connectivity — the Indra offers Wi-Fi and Bluetooth only, with no wired fallback. The EVO supports OCPP 1.6J, opening the door to third-party energy management platforms. The Indra doesn't.

Then there's the safety hardware. The Indra Smart PRO bundles a surge protection device (SPD), which typically saves £100–150 at installation. Fair enough. But the Rolec EVO includes built-in PME/PEN fault detection alongside a Type A RCD with 6mA DC protection. That PME detection can eliminate the need for a separate PEN device or earth rod — a saving of £100–200 depending on your installer and property. So when you factor in installation savings, the EVO's effective cost advantage over the Indra stretches well beyond the £150 sticker price difference.

At £449, the Rolec EVO is competitive with chargers on our cheapest EV charger list while offering a feature set that rivals units costing £200 more.

Tethered vs Untethered: Does It Actually Matter?

The Indra Smart PRO comes tethered with a 6-metre Type 2 cable. The Rolec EVO is untethered only — a Type 2 socket where you bring your own cable. For Tesla owners, this is a genuine consideration.

A tethered charger means you walk to the wall, grab the cable, and plug in. No rummaging in the boot, no coiling a cable back up afterwards. It's a small daily convenience that adds up. If your charger is in a garage or driveway where the cable hangs neatly, tethered is the obvious choice for ease of use.

The untethered EVO, on the other hand, offers flexibility. You can use different cable lengths, share the socket between vehicles with different connectors (though all UK Teslas use Type 2), and there's nothing dangling on your wall when the car isn't home. But you'll need to budget £50–100 for a decent Type 2 cable if you don't already have one, which narrows the price gap slightly.

If daily convenience is a priority, the Indra's tethered design is its strongest practical advantage over the Rolec.

Is Indra's V2G Pedigree Worth Paying For?

Indra markets itself as a V2G pioneer, and that's true — they make the Indra V2G charger, one of the few bidirectional units available in the UK. The Smart PRO, however, does not support V2G. The pitch is that buying into the Indra ecosystem now positions you for a future upgrade.

That's a thin argument for spending more today. V2G remains limited to a handful of vehicles, and there's no guarantee that owning a Smart PRO will offer any meaningful upgrade path or discount toward an Indra V2G unit later. Buy the Smart PRO if you like it on its current merits. Don't buy it as a speculative bet on vehicle-to-grid technology.

Warranty and Build Confidence

The Rolec EVO comes with a 5-year warranty. The Indra Smart PRO offers 3 years. For a piece of outdoor electrical equipment exposed to British weather year-round, that extra two years of cover is meaningful. Rolec has been manufacturing EV chargers in Lincolnshire for over a decade, and the EVO earned a Red Dot Award in 2024 — it's a compact, 3kg unit with IK10 impact resistance, the highest rating available.

The Indra is well-built too, but at a heavier 5kg and with a shorter warranty, it doesn't inspire the same long-term confidence. If you're comparing these two chargers as investments in your home, the Rolec's warranty is a tangible edge.

Which Should You Buy?

Buy the Indra Smart PRO if:

• You want a tethered charger with a permanently attached cable
• You're already in the Indra ecosystem or plan to explore V2G later
• Your installer doesn't charge separately for SPD but would charge for PEN fault detection
• You prefer a British brand with a focused product range

Buy the Rolec EVO if:

• You want the most features for the lowest price
• A 5-year warranty matters to you
• You have or plan to add solar panels and want built-in Eco/Eco+ modes
• You want built-in PME fault detection to minimise installation costs
• You're comfortable with an untethered socket

For most Tesla owners, the Rolec EVO is the smarter purchase. It undercuts the Indra by £150, outlasts it on warranty by two years, and includes safety hardware that will likely save you more at installation. The Indra Smart PRO is a perfectly decent charger — but the Rolec simply offers more for less.
