Octopus Energy has launched the Mercury Trust Mark, a groundbreaking certification designed to ensure that home energy devices—including electric vehicle (EV) chargers—are fully compatible with flexible home grids. This initiative aims to accelerate the nationwide shift to smarter, cleaner energy usage.
Acting like the “Bluetooth” of clean technology, the Mercury Trust Mark provides consumers with a clear and trusted signal that their devices can seamlessly connect to the grid and communicate reliably with other systems. It removes the guesswork often involved in choosing smart energy products, ensuring compatibility and performance in real-world conditions.
The first chargers to receive Mercury certification are the Zaptec Go 2, Easee One, and Octopus Charge. These pioneering products have already seen over a million installations across Europe, bringing smart energy technology directly to homes and driveways.

Unlike existing EV charging standards such as OCPP, which focus primarily on device connectivity, Mercury goes further by certifying how devices actually behave once connected. This means consumers can trust their chargers to interact optimally with the grid, making energy use more efficient and cost-effective.
While the initial focus is on EV chargers, the Mercury Trust Mark is set to expand to other household technologies including home batteries, electric vehicles themselves, as well as heating and cooling systems. This reflects a broader vision of integrating all smart energy devices under a unified, reliable certification.
Alex Schoch, Group Director of Flexibility & Electrification at Octopus Energy Group, emphasized the importance of this development: “An EV charger is not just a plug on the wall. Done right, it is the vital link between a customer’s car, their home, and a cleaner, cheaper grid. Mercury certification helps make that link easier to trust, so customers can reap the full financial rewards of smart charging without needing a degree in energy engineering to understand what is happening behind the scenes.”
Devrim Celal, Co-Chair of the Mercury Consortium, added, “Consumers shouldn’t have to become grid flexibility experts to know whether the tech they buy is future-proof. The Mercury mark makes that trust beautifully simple. These first certified chargers prove that smart energy devices can be tested once, recognized instantly by the market, and used to unlock cheaper, cleaner energy for households.”
