GivEnergy EV Charger vs Rolec EVO: does the home battery earn £29?

The £29 that only matters if you own a battery

These two sit within touching distance on price — the Rolec EVO at £449, the GivEnergy EV Charger at £478. A £29 gap. But the premium isn't for the charger; it's for a single feature that's either transformative or completely irrelevant, depending on what's already bolted to your wall.

• GivEnergy EV Charger — the battery-to-car specialist. Brilliant if you have home storage, ordinary if you don't.
• Rolec EVO — the quiet value pick. British-built, five-year warranty, and cheaper to install than almost anything at this price.

When the GivEnergy makes sense

The case is narrow and specific: you own a home battery — GivEnergy's own, or a compatible third-party unit — and you want to route cheap overnight electricity through it into the car during the day. Most chargers with "solar mode" can only siphon live generation. The GivEnergy EV Charger draws from stored energy too, which turns a daytime top-up into an overnight-tariff top-up without needing the car plugged in at 2am.

That's a real edge, and nothing at this price matches it. On Octopus Intelligent Go at 7p/kWh, filling a battery overnight and then slowly trickling it into the car during the working day is a legitimate strategy — particularly for households where the car leaves before the off-peak window closes.

Without a battery, though, the argument collapses. You're left with a tethered 7kW charger, a basic app, schedule-based tariff handling, and a three-year warranty — for £478. At that point the Easee One is £73 cheaper, the VCHRGD Seven Pro has more features, and the Ohme Home Pro actually talks to your supplier's API.

Why the Rolec EVO undercuts its own price tag

The £449 sticker understates the value. The Rolec EVO has PME fault detection, a Type A RCD, and surge protection built into the unit — which means your installer doesn't need a separate earth rod, PEN device, or additional RCD in the consumer unit. On most jobs that's £150–£250 off the labour and parts line. Effective unit cost drops well below the Tesla Wall Connector or Ohme Home Pro.

Then there's the warranty — five years, against three on the GivEnergy — from a Lincolnshire manufacturer with a decade of commercial charging behind it. Solar integration is handled through Eco and Eco+ surplus modes, and the CT clamp is in the box. Wi-Fi 6, Bluetooth 5.0 and Ethernet cover connectivity; the one omission worth flagging is 4G, so if your router can't reach the drive, the Cord Zero is the alternative.

The honest caveats: it's untethered only, there's no on-unit display, and the consumer app is still being refined. None of these are deal-breakers, but they're worth knowing before you click buy.

The tariff question

Both chargers do schedule-based tariff charging — set a window, charge in it. Neither has the live API integration that the Ohme Home Pro uses to chase half-hourly prices on Octopus Agile. So if you're an Agile household wanting the charger to hunt the cheapest 30-minute slots on your behalf, neither of these is the answer.

For fixed-window tariffs — Octopus Go, E.ON Next Drive, British Gas Electric Drivers — a scheduler is all you need, and both do it competently. On Intelligent Go, Octopus manages the charging window through the car's API anyway, so the charger's smarts don't much matter.

Solar buyers will find the matchup closer than expected — both do surplus diversion — but the right comparison there is probably the Zappi GLO vs GivEnergy page, where the solar-focused chargers square off properly.

The verdict

Buy the GivEnergy EV Charger if:

• You own, or are installing, a compatible home battery
• You want whole-home energy visibility through the GivEnergy portal
• A tethered cable matters to you (the Rolec is untethered only)

Buy the Rolec EVO if:

• You want the lowest total installed cost at this power level
• A five-year warranty and British manufacturing carry weight
• You're happy to supply your own Type 2 cable

If we had to put one on a wall tomorrow, it's the Rolec EVO. The home-battery use case is excellent, but it applies to a small slice of buyers; for the rest, Rolec delivers more warranty, lower install cost, and better build certification for £29 less. The battery-to-EV trick is the only reason to pay the GivEnergy premium — and if you already own the battery, you'll know it.
