Cord Zero vs Rolec EVO

The Rolec EVO is £106 cheaper at £449 compared to the Cord Zero at £555. The Cord Zero price is tethered 5m; 8m version £625; untethered £475.

When you factor in professional installation (typically £400–£600), the total installed cost for the Cord Zero is approximately £955–£1155, while the Rolec EVO comes in at around £849–£1049. Fully installed, the Rolec EVO remains the more affordable option.

Both the Cord Zero (7.4kW) and Rolec EVO (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.

The Cord Zero offers: Cord AI app, Scheduled charging, EV tariff integration, Solar compatible, Dynamic load balancing, RFID access control, OCPP 1.6J, Wi-Fi + 4G dual connectivity, Energy monitoring. The Rolec EVO offers: Rolec EVO app, Charge scheduling, Solar integration (Eco + Eco+ modes), Dynamic load balancing (CT clamp included), RFID (2 cards included), Wi-Fi 6 + Bluetooth 5.0 + Ethernet, OCPP 1.6J, Energy monitoring, PME/PEN fault detection, Built-in Type A RCD + 6mA DC protection.

Breaking these down by category: for connectivity, the Cord Zero uses Wi-Fi + 4G dual connectivity, while the Rolec EVO uses Wi-Fi 6 + Bluetooth 5.0 + Ethernet. For energy management, the Cord Zero provides Dynamic load balancing, Energy monitoring, compared to the Rolec EVO's Dynamic load balancing (CT clamp included), Energy monitoring. Solar and scheduling features are covered in the dedicated sections below.

Both the Cord Zero and Rolec EVO support solar integration, allowing you to charge your Tesla using surplus solar energy rather than drawing from the grid. The implementation and sophistication of solar diversion differs between the two, which can significantly affect how much free charging you actually get.

The Cord Zero supports solar diversion through its energy management system. The Rolec EVO supports solar diversion through its energy management system. The key difference is how precisely each charger tracks surplus generation — CT clamp-based systems typically offer more responsive diversion than those relying on smart meter data, which can have a slight delay.

The Cord Zero integrates with smart energy tariffs, automatically charging at the cheapest off-peak rates. The Rolec EVO 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 Cord Zero a meaningful advantage in running costs.

The Cord Zero 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 Cord Zero comes with a 3 years warranty, while the Rolec EVO offers 5 years. The Rolec EVO offers 2 years more coverage, giving you added peace of mind. 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 Cord Zero is rated IP54 + IK08 (weatherproof, impact-resistant) (splash-proof — protected against splashing water from any direction), while the Rolec EVO is rated IP54 + IK10 (weatherproof + highest impact resistance) (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.
